Answer:

(g◦f)(-6) = -9

Step-by-step explanation:

(g◦f)(-6) means g(f(-6))

Put the number where the variable is and evaluate.

f(-6) = 3/2(-6) +5 = -9 +5 = -4

g(f(-6)) = g(-4) = 7 -(-4)² = 7 -16 = -9

Then ...

(g◦f)(-6) = -9

(Round to the nearest tenth of a percent.) In 2011, the IRS increased the deductible mileage cost to

RUDIKE [14]

Answer:

$\%Change = 8.8\%$

Step-by-step explanation:

Given

$Initial = 51\ cents$

$Final = 55.5\ cents$

Required

Determine the percentage change

Percentage change is calculated as;

$\%Change = \frac{Final - Initial}{Initial} * 100\%$

$\%Change = \frac{55.5 - 51 }{51 } * 100\%$

$\%Change = \frac{4.5}{51} * 100\%$

$\%Change = \frac{4.5* 100\%}{51}$

$\%Change = \frac{450\%}{51}$

$\%Change = 8.8\%$

<em>Hence, the percentage change is approximately 8.8%</em>

R^2+8r=-7<br>solve the equation with the quadratic formula showing work

Yuliya22 [10]

Answer:

Step-by-step explanation:

r²+8r=−7

Step 1: Subtract -7 from both sides.

r²+8r−(−7)=−7−(−7)

r²+8r+7=0

Step 2: Use quadratic formula with a=1, b=8, c=7.

r= $r=\frac{-b+or-\sqrt{-4ac} }{2a}$

$r=\frac{-8+or-\sqrt{(8})^2-4(1)(7) }{2(1)}$

What value of x makes the equation 3(x-6)-8x= -2+5(2x+1) true

QveST [7]

Answer:

x= −7/5

Step-by-step explanation:

Step 1: Distribute and combine like terms

3(x−6)−8x=−2+5(2x+1)

(3)(x)+(3)(−6)+−8x=−2+(5)(2x)+(5)(1)(Distribute)

3x+−18+−8x=−2+10x+5

(3x+−8x)+(−18)=(10x)+(−2+5)(Combine Like Terms)

−5x+−18=10x+3

−5x−18=10x+3

Step 2: Subtract 10x from both sides.

−5x−18−10x=10x+3−10x

−15x−18=3

Step 3: Add 18 to both sides.

−15x−18+18=3+18

−15x=21

Step 4: Divide both sides by -15.

Hope this helps! :)
