Answer:

15x² +8x +3

Step-by-step explanation:

Use the distributive property and combine terms.

(5x² +1)(2x +3) -2x(5x² -3)

= 5x²(2x +3) +1(2x +3) -2x(5x² -3)

= 10x³+15x² +2x +3 -10x³ +6x

= (10 -10)x³ +15x² +(2 +6)x +3

= 15x² +8x +3

Answer:

56 and 43

Step-by-step explanation:

(x+13)+x = 99

2x+13 = 99

2x = 99-13

2x = 86

x = 86/2

x = 43

Smaller number = 43

Larger number is 56

Check

56-43 = 13

56+43 = 99

A scatter plot is made to model the amount of money left to pay on a credit card. The data used for the scatter plot are shown i

Option d: The original balance on the credit card.

Explanation:

To determine the y-intercept, let us use the formula,

$y=mx+b$ where m is the slope and b is the y-intercept.

Also, $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Let us choose the coordinates $(3,1400)$ and $(5,1000)$

Substituting, we get,

$m=\frac{1000-1400}{5-3} =\frac{-400}{2} =-200$

Thus, the formula becomes

$y=-200x+b$

Now, to determine the value of b, let us substitute $(1,1800)$ in the formula,

we get,

$\begin{aligned}&1800=-200(1)+b\\&2000=b\end{aligned}$

Substituting the value of b in the formula, we have,

$y=-200 x+2000$

Thus, the y-intercept is $b=2000$

At y-intercept the value of x is 0. It means the y-intercept represents the amount of money left to pay on a credit card when the number of months is 0.

Thus, the y-intercept represents the original balance on the credit card.

Hence, Option d is the correct answer.
