Express your answer as a polynomial in standard form.

Juli2301 [7.4K]

Answer:

(f o g)(x) = -2x² - x + 4

Step-by-step explanation:

f(x) = -x + 6

g(x) = 2x² + x + 2

To find (f o g)(x), you need put g(x) into f(x).

f(x) = -x + 6

(f o g)(x) = -(2x² + x + 2) + 6

(f o g)(x) = -2x² - x - 2 + 6

(f o g)(x) = -2x² - x + 4

2. If GFE~GJH, find the value of FG.

Alex73 [517]

Answer:

77 units

Step-by-step explanation:

Given two similar triangles.

Corresponding parts of similar figures have same ratio.

Use ratios to find the value of x:

(4x - 5)/(x + 7) = 35/12.5
(4x - 5)/(x + 7) = 14/5
5(4x - 5) = 14(x + 7)
20x - 25 = 14x + 98
20x - 14x = 98 + 25
6x = 123
x = 123/6
x = 20.5

Find the value of FG:

FG = 4*20.5 - 5 = 77

Apples cost $3.60 for 3 lb. At that rate, how many pounds of apples can you buy for $8.40?

irinina [24]

Apples cost $3.60 for 3 pounds . The rate can be calculated as follows

$\begin{gathered} 3\text{ pounds = \$3.60} \\ 1\text{ pounds = ?} \\ \text{rate = }\frac{3.60}{3} \\ \text{rate}=\text{ \$1.2 per pound} \end{gathered}$

The amount of pounds you can buy for $8.40 can be computed below

$\begin{gathered} \text{rate}=\frac{8.40}{\text{pounds}} \\ 1.2=\frac{8.40}{\text{pounds}} \\ weight\text{ in pounds = }\frac{8.40}{1.2} \\ \text{weight in pounds = 7 Ib} \end{gathered}$
