Answer:
y=-3/4x-1
Step-by-step explanation:
y=mx+b; y is the y coordinate; m is the slope; x is the x coordinate; you have to find b. So you replace all the numbers out which is given to you;
-4=-3/4(4)+b (you multiply -3/4 by 4 and get -3)
-4=-3+b (you add 3 to both sides and get -1)
-1=b (you now found b so plug it into the equation)
y=-3/4x-1
Identify the property of equality that justifies the missing step in solving the equation below
Answer:
property of equality that justifies the missing step is Division property of equality
Step-by-step explanation:
We need to Identify the property of equality that justifies the missing step
[tex]28=4x-8\\28+8=4x\\36=4x[/tex]
Now, we divide both sides by 4 using division property of equality as it states that [tex]\frac{a}{c}=\frac{b}{c}[/tex]
[tex]\frac{36}{4}=\frac{4x}{4}\\9=x[/tex]
So, The property of equality that justifies the missing step is Division property of equality
what is the value of x?
help would be so appreciated!
Answer:
x =23
Step-by-step explanation:
ok first, the full degree of a straight line is 180°
subtract 38° out of 180°
180-38= 142
so 6x+4= 142°
subtract 4 from both sides of the equation
6x +4 -4= 142-4
6x=138
divide 6 from 6x and 138
x=23
Is ( ¬ (( ∨ ( ∧ )) ∨ ( → ))) logically equivalent to (¬ ((( ¬ (¬)) ∨ ) ∨ ))?
Answer:
of course
Step-by-step explanation:
On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?
That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)

solve linear equation
[tex] \Large{\boxed{\sf x = 4}} [/tex]
[tex] \\ [/tex]
Explanation:Solving this equation means finding the value of 'x' that makes the equality true.
[tex] \\ [/tex]
Given equation:
[tex] \sf -12 + 5x - x = x - 7 + 7 [/tex]
[tex] \\ [/tex]
Combine like terms:
[tex] \sf -12 + (5x - x) = x + (-7 + 7) \\ \\ \sf -12 + 4x = x [/tex]
[tex] \\ [/tex]
Now, we move the variables to the right side of the equation by subtracting 4x from both sides:
[tex] \sf -12 + 4x - 4x = x - 4x \\ \\ \sf -12 = -3x [/tex]
[tex] \\ [/tex]
Finally, divide both sides of the equation by the coefficient of the variable, -3:
[tex] \sf \dfrac{-12}{-3} = \dfrac{-3x}{-3} \\ \\ \\ \boxed{\boxed{\sf x = 4}} [/tex]
[tex] \\ \\ [/tex]

Answer:−589.86
Step-by-step explanation:
let unknown number be x
Solve for x
655.4+x=65.54
Subtract 655.4 from both sides.
x=65.54−655.4

Question 4
Ralph deposited $10,500 in an CD account that pays 1.75% simple interest for 30 months.
How much interest will this CD have earned after 30 months?
$
What is the new balance at maturity (30 months)?
2 pts
The CD will earn $459.375 interest in 30 months and the balance at maturity will be $10,959.375.
Here, we are given that Ralph deposited $10,500 in an CD account that pays 1.75% simple interest for 30 months.
Simple interest can be calculated using the following formula-
Simple interest = Principle(P) × Time(t) × Rate(r)/ 100
Here,
P = 10,500
t = 30/12
r = 1.75
Thus,
Simple interest = 10,500 × 30/12 × 1.75/ 100
= 10,500 × 5/2 × 175/ 10000
= 10,500 × 5/2 × 7/ 400
= 26,250 × 7/ 400
= $459.375
Thus, the CD will earn $459.375 interest in 30 months.
Balance on maturity will be-
$10,500+ $459.375 = 10,959.375
Thus, the balance at maturity will be $10,959.375.

Help me out from 25-32 also show work (Geometry)
Answer:
Step-by-step explanation:
25.
x + 2x -75 = 90
3x = 90+75
3x = 165
x = 55
Measure of A = 55
Measure of B = 2(55) - 75 = 110 - 75 = 35
28.
2x+10-x+55 = 90
x = 90-65
x = 25
measure of A = 2(25) +10 = 60
measure of B = -25+55 = 30
31.
2x+3+3x - 223 = 180
5x -220 = 180
5x = 400
x = 80
measure of A = 163
measure of B = 17
32.
-4x+40+x+50 = 180
-3x +90 = 180
-3x = 90
x= -30
measure of A = -4(-30) +40 = 160
measure of B = -30+50 = 20

Read the excerpt from The Crisis, Number I by Thomas Paine.
“I once felt all that kind of anger, which a man ought to feel, against the mean principles that are held by the Tories: a noted one, who kept a tavern at Amboy, was standing at his door, with as pretty a child in his hand, about eight or nine years old, as I ever saw, and after speaking his mind as freely as he thought was prudent, finished with this unfatherly expression, ‘Well! give me peace in my day.’ Not a man lives on the continent but fully believes that a separation must some time or other finally take place, and a generous parent should have said, ‘If there must be trouble, let it be in my day, that my child may have peace;’ and this single reflection, well applied, is sufficient to awaken every man to duty.”
Which is a central idea of this excerpt?
Paine feels that everyone should be able to speak freely, which is why he supports independence.
Paine believes that colonists should fight for independence so their children can live in peace.
Paine believes that some people are selfish and place their needs above others.
Paine felt anger for the first time when he saw an interaction between a Tory and a child.
Nicole bought six pounds of apples at $1.50 per pound. The store had a discount of $2 off her total purchase. Nicole and her friend then divided the cost of the purchase evenly. Which expression can be used to determine how much Nicole and her friend each paid for the apples?

Answer:
Answer: (A) [(6 x 1.5) - 2] ÷ 2
Step-by-step explanation:
Find the cost of 6 pounds of apples:
1 pound = $1.50
6 pounds = 6 x 1.5

Can someone explain these two?
Answer:
I believe you cancel out values if there are the same ones for the numerator and dominator.
For example:
[tex]\frac{x^4+x^2+x-3}{x^4+x^3-3}[/tex]
Since both the numerator and dominator have [tex]x^4[/tex] and -3, you are able to cancel them out.
This would leave you with [tex]\frac{x^2+x}{x^3}[/tex]
Notes: the exponents have to be the same number in order to cancel out the values.
Answer:
11. C) x +1
12. B) x -1
Step-by-step explanation:
You want the simplified form of a couple given rational expressions.
Each of the polynomials can be factored by pairs. Common factors can be cancelled.
11.Factoring numerator and denominator pairwise, we have ...
[tex]\dfrac{x^3+2x^2-x-2}{x^2+2x-x-2}=\dfrac{x^2(x+2)-1(x+2)}{x(x+2)-1(x+2)}=\dfrac{(x^2-1)(x+2)}{(x-1)(x+2)}\\\\=\dfrac{x^2-1}{x-1}=\dfrac{(x+1)(x-1)}{(x-1)}=\boxed{x+1}[/tex]
12.Factoring the numerator pairwise,, we have ...
[tex]\dfrac{x^5-x^4+x^3-x^2+x-1}{x^4+x^2+1}=\dfrac{x^4(x-1)+x^2(x-1)+1(x-1)}{x^4+x^2+1}\\\\=\dfrac{(x^4+x^2+1)(x-1)}{(x^4+x^2+1)}=\boxed{x-1}[/tex]
