HERE IS YOUR ANSWER
Step-by-step explanation:
The standard form of a linear equation is
Ax+By=C,A,B≠0Ax+By=C,A,B≠0
Before you can graph a linear equation in its standard form you first have to solve the equation for y.
2y−4x=82y−4x=8
2y−4x+4x=8+4x2y−4x+4x=8+4x
2y=4x+82y=4x+8
2y2=4x2+822y2=4x2+82
y=2x+4
(-1, -7), (3/4, 0),(1,1),(2,5) are the points in the coordinate plane that lie on the graph of the linear equation 4x - y = 3.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given points in the coordinate plane that lie on the graph of the linear equation 4x - y = 3.
For (-1,-7)
4(-1)-(-7)=3
3=3
So the point (-1, -7) lie on the line.
(0,3)
4(0)-3=3
-3=3
the point (0,3) does not lie on the line.
For point (3/4, 0)
4(3/4)-0=3
3=3
the point (3/4,0) lie on the line.
For point (1,1)
4-1=3
3=3
The point (1,1) lie on the line.
For point (2,5)
8-5=3
3=3
The point (2,5) lie on the line.
For point (4,-1)
16+1=3
17=3
For point (4,-1) does not lie on the line.
Hence, (-1, -7), (3/4, 0),(1,1),(2,5) are the points in the coordinate plane that lie on the graph of the linear equation 4x - y = 3.

Step-by-step explanation:
Does (-3, 3) make the equation y = -3x true?
========================================================
Explanation:
The point (-3,3) means x = -3 and y = 3 pair up together
So plugging in x = -3 should lead to y = 3 if (-3,3) was a solution
Plug x = -3 into y = -3x to find that
y = -3x
y = -3*(-3)
y = 9
So x = -3 and y = 9 should be the actual pair (not x = -3 and y = 3)
---------------
Put another way
y = -3x
3 = -3(-3) ... replace x with -3 and y with 3
3 = 9 ... which is false
This shows (x,y) = (-3,3) is not a solution

Answer:
2) V = 2000·1.07^t; $6317.63 after 17 years
3) D = 950·0.82^t; 2 months to a balance of $650
Step-by-step explanation:
Exponential equations are not so difficult. They are generally of the form ...
f(t) = (initial value) × (growth factor)^t
where t is the number of time periods to which growth factor applies. (I problem 2, that is years; in problem 3, that is months.)
The growth factor can be written different ways. In terms of growth rate, it is ...
growth factor = 1 + growth rate
Often, the growth rate is expressed as a percentage. It may be positive or negative.
__
2) The initial value is $2000, and the growth rate is 7% = 0.07. So, the exponential equation for value is ...
V = 2000·1.07^t
The value after 17 years is ...
V = 2000·1.07^17 = 6317.63
__
3) The initial value is $950, and the growth rate is -18% = -0.18. That means the growth factor is 1-0.18 = 0.82. So, the exponential equation for the remaining debt is ...
D = 950·0.82^t . . . . . where t is in months
We want to find the value of t when D=650, so we put that in the equation and solve for t. Logarithms are required.
650 = 950·0.82^t
650/950 = 0.82^t . . . . . . . . . . divide by 950
log(650/950) = t·log(0.82) . . . take logarithms
log(650/950)/log(0.82) = t ≈ 1.91
It will take about 2 months for the balance to be about $650.

Answer:
A
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse h is equal to the sum of the squares on the other 2 sides, that is
h² = 20² + 20² = 400 + 400 = 800 ( take the square root of both sides )
h = [tex]\sqrt{800}[/tex] ≈ 28 in ( to the nearest whole number )

D. -2i
Answer:
[tex] - 2i[/tex]
Step-by-step explanation:
[tex]f(x) = { \times }^{3} + 3 {x}^{2} + 4x + 12 \\ = ( {x}^{3} + 3x^{2}) +(4x + 12) = \\ {x}^{2} (x + 3) + 4(x + 3) = \\ ( {x}^{2} + 4)(x + 3) [/tex]
Point Q lies on segment ST, where point S is located at (- 3, - 3) and location of point T is unknown. If SQ : QT = 4 : 3, and point Q is located at (3, 0) on the segment ST, select a place on the coordinate grid to plot point T and name its coordinate.
Answer:
The location of point T is [tex]\vec T = (7.5, 2.25)[/tex]. Graph is included at the end of the explanation as attachment.
Step-by-step explanation:
The SQ : QT ratio means that there are 4 units of SQ for each 3 units of QT. Vectorially speaking, we notice that:
[tex]\overrightarrow {SQ} = \frac{4}{7}\cdot \overrightarrow {ST}[/tex] (Eq. 1)
[tex]\overrightarrow{QT} = \frac{3}{7}\cdot \overrightarrow {ST}[/tex] (Eq. 2)
Now, we eliminate [tex]\overrightarrow{ST}[/tex] by equalizing (Eq. 1) and (Eq. 2):
[tex]\frac{7}{3} \cdot \overrightarrow{QT} = \frac{7}{4}\cdot \overrightarrow{SQ}[/tex] (Eq. 3)
From Linear Algebra, we know that:
[tex]\frac{7}{3}\cdot (\vec T - \vec Q) = \frac{7}{4}\cdot (\vec Q-\vec S)[/tex] (Eq. 3b)
And we clear [tex]\vec T[/tex]
[tex]\frac{7}{3}\cdot \vec T -\frac{7}{3}\cdot \vec Q = \frac{7}{4}\cdot \vec Q -\frac{7}{4}\cdot \vec S[/tex]
[tex]\frac{7}{3}\cdot \vec T = \frac{49}{12}\cdot \vec Q - \frac{7}{4}\cdot \vec S[/tex]
[tex]\vec T = \frac{3}{7}\cdot \left(\frac{49}{12}\cdot \vec Q-\frac{7}{4}\cdot \vec S\right)[/tex]
[tex]\vec T = \frac{7}{4}\cdot \vec Q-\frac{3}{4}\cdot \vec S[/tex]
If we know that [tex]Q(x,y) = (3, 0)[/tex] and [tex]S(x, y) = (-3,-3)[/tex], then we have that [tex]T(x,y)[/tex] is:
[tex]\vec T = \frac{7}{4}\cdot (3, 0) - \frac{3}{4}\cdot (-3, -3)[/tex]
[tex]\vec T = \left(\frac{21}{4}, 0 \right) + \left(\frac{9}{4},\frac{9}{4}\right)[/tex]
[tex]\vec T = \left(\frac{21+9}{4},\frac{0+9}{4} \right)[/tex]
[tex]\vec T = \left(\frac{15}{2}, \frac{9}{4}\right)[/tex]
[tex]\vec T = (7.5, 2.25)[/tex]
At last we plot the segment with all points described on statement. We can check the result in the attachment set below.
Why would your savings account “lose value” if the rate of return you receive is lower than the rate of inflation?
Answer:
Inflation is the continuing reduction of the purchasing power or price level rise in a given time period.
Therefore, keeping money in a savings account that gives an interest rate that is lower than the inflation rate, in a period of high inflation will result in a reduction of the purchasing power of the amount of money plus interest in the savings account.
If the interest rate is 10%, the amount, A, in the account after a given time will be 1.1A
If the inflation rate is 15%, the value of the goods sold initially at A, will become 1.15A after the given period and the amount in the account will no longer be able to purchase the goods it was initially able to purchase, or the amount in the savings account will lose value
Step-by-step explanation:
In this exercise, we have to know some finances concepts in order to explain the problematized situation in this way we can say that:
Inflation exist the ongoing decline of the ability to purchase or price level rise fashionable a likely time period.
Explaining this concept of finance in a deeper way, we find that:
Inflation exist the ongoing decline of the purchasing power or price level rise fashionable a likely an age.
Therefore, consistency services in a account for saved money that gives an sum charged for use of money that is to say inferior the swelling rate, in a period of extreme swelling will influence a decline of the ability to purchase of the amount of services plus interest in the account for saved money.
If the sum charged for use of money exist 10%, the amount, A, fashionable the or charges after a likely opportunity will exist 1.1A
If the swelling rate exist 15%, the value of ability sold out at first at A, will evolve into 1.15A following in position or time the given extent of time and the amount fashionable the or charges will not any more within financial means purchase the goods it exist at first able to perform well to purchase, or the amount fashionable the account for saved money will lose value

How many four-digit counting numbers are not multiples of 5?
Answer:
1000 to 9999 are all of the 4-digit counting numbers
1 to 9999 gives 9999 counting numbers, but we are leaving out 999 of them
9999-999=9000 counting numbers that are 4-digit numbers
9000-1800=7200 4-digit numbers that are not multiples of 5
Step-by-step explanation:
There are 7,000 four-digit counting numbers that are not multiples of 5.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find the number of four-digit counting numbers that are not multiples of 5, we need to find the total number of four-digit counting numbers and then subtract the number of four-digit counting numbers that are multiples of 5.
There are 9 choices for the first digit (it cannot be 0, since we are looking at four-digit numbers), and 10 choices for each of the remaining three digits (they can be 0-9).
So, the total number of four-digit counting numbers is:
9 × 10 × 10 × 10
= 9,000
To find the number of four-digit counting numbers that are multiples of 5, we need to consider the last digit.
Since a number is a multiple of 5 if and only if its last digit is 0 or 5, there are 2 choices for the last digit.
The first three digits can be any of the 10 digits, so there are:
10 × 10 × 10 × 2 = 2,000
four-digit counting numbers that are multiples of 5.
Therefore, the number of four-digit counting numbers that are not multiples of 5 is:
9,000 - 2,000 = 7,000
Thus,
There are 7,000 four-digit counting numbers that are not multiples of 5.
