Write an equation that will satisfy the x and y values in the table below.
Answer:
The equation that will satisfy x and y values in the table is y = 2x + 3
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the line that represents the equation b is the y-intercept, value y at x = 0The rule of the slope of the line is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the lineFrom the given table
∵ x = 0 and y = 3, x = 1 and y = 5
∴ x1 = 0 and x2 = 1
∴ y1 = 3 and y2 = 5
→ Substitute them in the rule of the slope above
∵ m = [tex]\frac{5-3}{1-0}[/tex] = [tex]\frac{2}{1}[/tex]
∴ m = 2
∵ b is the value of y at x = 0
∵ y = 3 at x = 0
∴ b = 3
→ Substitute the values of m, b in the form of the equation above
∴ y = 2x + 3
∴ The equation that will satisfy x and y values in the table is y = 2x + 3
Which equations represent functions?
2x + 3y = 10
4x = 16
2x − 3 = 14
3y = 18

Answer:
transitive property of equality
Step-by-step explanation:
The transitive property of equality says ...
if a = b and b = c, then a = c.
Here, we can use this form with ...
a = 2x+4
b = y
c = 3x-6
__
We have ...
a = b ⇒ 2x +4 = y
b = c ⇒ y = 3x -6
so, ...
a = c ⇒ 2x +4 = 3x -6 . . . . transitive property of equality.
_____
On the other hand, ...
The substitution property of equality says ...
if a = b, we can use b wherever 'a' is seen.
We can use this with ...
a = y
b = 3x -6
and do the substitution in the equation ...
2x +4 = y
Replacing y with its equal, we get ...
2x +4 = 'a' ⇒ 2x +4 = 'b' ⇒ 2x +4 = 3x -6 . . . . substitution property of equality
_____
Additional comment
These are two different ways to say that anything can be replaced by its equal.
P(x) = 2x3 – x2 + 4x + 5 is divided by x + 2. Choose the correct option from each drop-down menu.
When P(x) is divided by x + 2, the remainder is [ ] P(–2) = [ ]. The Remainder Theorem is [verfied/not verified] ]
The remainder of the division of polynomial, P(x) = 2x3 – x2 + 4x + 5 by (x + 2) is; -23
The remainder of the division of the polynomial, P(x) = 2x3 – x2 + 4x + 5 by (x + 2) can be evaluated by the remainder theorem.
This involves adding evaluating the value of the polynomial at, x = -2.
Since, (x +2) is the Divisor, we evaluate, P(x) at x = -2Therefore, we have;
P(-2) = 2 ×(-2)³ -(-2)² + 4(-2) + 5P(-2) = -16 -4 -8 +5P(-2) = -23.Therefore, the remainder when P(x) = 2x3 – x2 + 4x + 5 is divided by (x + 2) is; -23

Answer:
(h-g)(x) = x^3 - 5x -5
Step-by-step explanation:
h(x)= x^3 - 2x and g(x)= 3x +5
(h-g)(x) = x^3 - 2x -( 3x +5)

The bar chart shows the percent of times each color marble was drawn from a bag after 1000 draws with replacement after each draw. If there are 20 marbles in the bag, predict how many are red, how many are blue, and how many are white. Explain your reasoning.
Answer:
Following are the solution to this question:
Step-by-step explanation:
In this question, the graph file is missing so, its solution can be defined as follows:
When the bag includes 20 marbles, each will be drawn 5% of the time on average.
The bar chart shows that nearly 50% of the workforce red marbles are drawn, and about 25% of the time blue and white marbles are drawn. so, the equation is:
[tex]\to \frac{50\%}{5\%}= \frac{50 \times 100}{5\times 100}=\frac{50}{5} = 10 \ red \ marbles\\\\\to \frac{25\%}{5\%}= \frac{25 \times 100}{5\times 100}=\frac{25}{5} = 5\ blue \ marbles[/tex]
[tex]\to 5[/tex] white marbles are available in the bag.

Answer:
Step-by-step explanation:
this is a 30 60 90 triangle.. b/c 2 of the angles are given and you know the total is 180 around a triangle so the last angle is 30
also you know the hypotenuse of this triangle is 10 so use cos and sin to figure out the other sides
Use SOH CAH TOA to remember how the sin and cos functions fit on the triangle
CAH = Cos(Ф) = Adj/ Hyp we are given the Ф angle and we know the hypotenuse so solve for the Adj side
Hyp*Cos(Ф)= Adj
10 * Cos(60) = Adj
5 = Adj = y
Use Sin for the other side and the mnemonic to remember how it fits on the triangle and solve for the Opposite , since we don't know that .. yet
Sin(Ф) = Opp/ Hyp
Hyp * Sin (Ф) = Opp
10 * Sin(60) = Opp
10 *[tex]\sqrt{3}[/tex]/2 = Opp
5*[tex]\sqrt{3}[/tex] = Opp = x
:) I know Sin(60) = [tex]\sqrt{3}[/tex]/2 from a table and also my memory .. know that one from memory

Let us consider a rectangle [tex]ABCD[/tex] as shown in the attached image in the answer area.
We are given the two adjacent sides of a rectangle and we have to find diagonal of the rectangle.
To find the diagonal, we can use the Pythagorean Theorem.
We are given the base and perpendicular of the right angled triangle and we have to find the hypotenuse.
According to Pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}[/tex]
[tex]Diagonal = 20^2 + 32^2\\\Rightarrow Diagonal = 400 + 1024\\\Rightarrow Diagonal = \bold{37.7\ ft}[/tex]

The following rectangle has an area of 3x^2-5x-12. What are the possible side lengths, in terms of x? Explain your answer and justify how you know that the sides you found are possible lengths
Answer:
the possible side lengths:
3x+4 and x-3
Step-by-step explanation:
factorize the the expression and you will get two expressions in terms of x. those expressions are the lengths of the rectangle
[tex]3 {x}^{2} - 5x - 12[/tex]
1) write -5x as a difference
[tex]3 {x}^{2} + 4x - 9x - 12[/tex]
2) factor out x from the expression 3x²+4x
[tex]x(3x + 4) - 9x - 12[/tex]
3) factor out -3 from the expression -9x-12
[tex]x(3x + 4) - 3(3x + 4)[/tex]
4) factor out 3x+4 from the expression
[tex](3x + 4)( x - 3)[/tex]
the possible lengths are 3x+4 and x-3
to check whether the answer is correct, you can just multiply the both lengths using the area of rectangle formulae
area of rectangle formulae
[tex]length \times height[/tex]
(3x+4)(x-3)
= 3x²-9x+4x-12
= 3x²-5x-12 ( proven )

Total = 18 + 12 + 20
Total = 50
Then the percentage of the students who chose vanilla as their favorite ice cream flavor will be given as,
P = (20 / 50) x 100
P = 0.40 x 100
P = 40%

The number of camera phones shipped globally can be modeled by the function y = 1.28e 1.31x where x is the number of years since 1997 and y is the number of camera phones shipped (in millions). How many camera phones were shipped in 2002? Please helpASAP
Answer:
895 million camera phones
Step-by-step explanation:
Since the function is modeled by;
y=1.28e^1.31x
Now between 1997 - 2002 we have 5 years. This means that x =5. So we have to substitute x = 5 into the function to obtain the number of camera phones shipped in 2002.
Therefore;
y=1.28e^1.31(5)
y = 895 million camera phones
