Answer:

Step-by-step explanation:

$7+4y=39\\\\\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides}\\7+4y-7=39-7\\\\\mathrm{Simplify}\\4y=32\\\\\mathrm{Divide\:both\:sides\:by\:}4\\\frac{4y}{4}=\frac{32}{4}\\\\Simplify\\y =8$

Answer:

<em />

Step-by-step explanation:

7 + 4y = 39

Rearrange:

4y + 7 = 39

Subtract 7 from both sides:

4y + 7 = 39

- 7 -7

4y = 32

Divide both sides by 4:

4/4 = y

32/4 = 8

Answer:

Step-by-step explanation:

(1). A = π r²

A = 4 π

Area of shaded region is $\frac{4\pi *260}{360}$ = $\frac{26}{9} \pi$ or $\frac{26\pi }{9}$

(2). C = 4 π

In this case, the length of the bigger arc and the area of shaded region happen to be the same.

The length of the arc ADB is $\frac{26}{9} \pi$ or $\frac{26\pi }{9}$

What is the inverse of y= 3/2x -2

Mashcka [7]

Answer:

f^-1(x) = (2x + 4) / 3

Step-by-step explanation:

- switch 'y' with 'x'

x = 3/2y - 2

- solve for 'y'

x + 2 = 3/2y

- multiply each side by 2

y = (2x + 4) / 3
