The little lines crossing the sides of the triangle mean that the 2 sides are identical.

When 2 sides are identical the 2 bottom angles are the same, so 73 and 8y-7 are both 73 degrees. 73 +73 = 146 degrees.

This would mean the third angle ( 6x+4) needs to equal 180 - 146 = 34 degrees.

Now we can find X:

6x+4 = 34

Subtract 4 from each side:

6x = 30

Divide each side by 6:

x = 30/6

X = 5

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

Step-by-step explanation:

<u>Step 1: Define</u>

Point (16, -11)

Point (7, 0)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute [SF]:                    m=\frac{0+11}{7-16}
  2. Add/Subtract:                      m=\frac{11}{-9}

Jess deposited $5,000 into an account that earns simple interest. After 9 years, Jess had earned $3,150 in interest. What was th
musickatia [10]

Answer:

The interest rate of Jess's account was 7%

Step-by-step explanation:

A = P * (1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

Replacing with the values we know:

A =  P * (1 + rt)

8,150 = 5,000 * (1 + r * 9)

8,150/5,000 = 1 + 9r

1.63 = 1 + 9r

1.63 - 1 = 9r

0.63 = 9r

r = 063/9

r = 0.07 = 7%

The interest rate of Jess's account was 7%
