Select the correct answer.

zysi [14]

Answer:

A. -5x = -23

Step-by-step explanation:

First you have to simplify the equation - 4(x - 5) + 8x = 9x - 3

-4x + 20 + 8x = 9x -3

9x - 4x = 20 + 3

5x = 23

=> equivalent to answer A.

Tema [17]

Answer:

Step-by-step explanation:

$\boxed{area \: of \: sector = \frac{1}{2} {r}^{2} θ }$

Radius= diameter ÷2

r= 32 ÷2

r= 16

$\frac{1}{2} {r}^{2} θ = \frac{512\pi}{3}$

Substitute r= 16,

$\frac{1}{2} ( {16}^{2} )(θ) = \frac{512\pi}{3}$

$128 \: θ = \frac{512\pi}{3} \\ θ = \frac{512\pi}{3} \div 128 \\ θ = \frac{512\pi}{384}$

Divide the denominator and numerator by 128:

$θ = \frac{4\pi}{3}$

Thus, the answer is B.

Nina [5.8K]

Answer:

c = 8.14 million×(0.9166)^t

4.83 million

Step-by-step explanation:

Data:

t = y - 2007

c₀ = 8.14 million

c₃ = 23 % less than c₁

Part 1. Calculate c₃

c₃ = c₀(1 - 0.23) = 0.77c₀

Part 2. Calculate r

c₃ = c₀r^t

0.77c₀ = c₀r³

0.77 = r³ Divided each side by c₀

r = 0.9166 Took the cube root of each side

The explicit decay model is c = 8.14 million×(0.9166)^t

Part 3. Prediction

t = 2013 - 2007 = 6

c = c₀r^t = 8.14 million×(0.9166)⁶ = 8.14 million × 0.5929 = 4.83 million

The model predicts that there will be 4.83 million cars for sale in 2013.
