B, if you distribute you get 2(times) 9x which is 18x and 2x-3 which is -6

so that would be 18x-6

A, B, & E

A because 16.4x + 1.6x equals 18x.

B and E require that you use te distributive property therefore 2 times 9x equals 18 x and 2 times -3 = -6. For E 6 times 3x = 18x and 6 times -1 = -6

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from table.

Point (-1, -1)

Point (0, -5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m. Rate of change and slope are identical.

Substitute [SF]: $m=\frac{-5+1}{0+1}$
Add: $m=\frac{-4}{1}$
Divide: $m=-4$

astraxan [27]

The investment value will be $465.15.The amount he invested will be $200.

<h3>What is compound interest?</h3>

Compound interest is computed on a loan or deposit based on the starting principle and the preceding period's accrued interest.

Money invest one time in six months = $20

Interest = 17%

Compounded type = semi-annually

The principal amount invested:

Money invested = $ 20 in 6 month

If he invests for 5 years, in 5 years there are 10 times she invests;

Investment(principal)=$ 20 × 10

Investment(principal)=$ 200

The compound interest:

$A= 200(1+\frac{0.17}{2})^2.5 \\\\ A=$ \ 452.2$

A =P+CI

452.2=200+CI

CI=252.2

The final balance is $452.2.

The total compound interest is $252.2.

Hence, the investment value will be $452.2.
