Answer:

(- 8, 8 )

Step-by-step explanation:

Given ( ?, 8 ) is a solution. To find x substitute y = 8 into the equation, then

- 4x - 8 = 24 ( add 8 to both sides )

- 4x = 32 ( divide both sides by - 4 )

x = - 8

Thus solution is (- 8, 8 )

I really need help pleaseee

Answer:

P=163,487,500

Step-by-step explanation: P=Ae^(kt)

151000000=145000000*e^(k5)

151000000/14500000=e^(k5)

1.04137931=e^(k5)

Ln 1.04=Ln e^(k5)

0.04=k5

k= 0.008

P=145,000,000*e^(.008*15)

P=145,000,000*e^0.12

e=2.71828

P=145,000,000*1.12749685

p=163,487,500

What is AE?<br> Enter your answer in the box?

Nataly [62]

Answer:

AE = 18 units

Step-by-step explanation:

Δ AEB and Δ DEC are similar , then corresponding sides are in proportion, that is

$\frac{AE}{DE}$ = $\frac{AB}{DC}$ , substitute values

$\frac{2x+4}{x+8}$ = $\frac{12}{10}$ ( cross- multiply )

10(2x + 4) = 12(x + 8) ← distribute parenthesis on both sides

20x + 40 = 12x + 96 ( subtract 12x from both sides )

8x + 40 = 96 ( subtract 40 from both sides )

8x = 56 ( divide both sides by 8 )

x = 7

Then

AE = 2x + 4 = 2(7) + 4 = 14 + 4 = 18 units
