Slope of the line = 4 / 4.5 = 8/9
and it passes through the point (-4.-1) so we have

y - -1 = 8/9)x - -4)

y + 1 = 8/9 x + 32/9

* through by 9:-

9y + 9 = 8x + 32

9y = 8x + 32 - 9

8x - 9y = -32 + 9

8x - 9y = -23 is ur answer.

he value of y varies directly with the value of x. When y = 32.5, x = 5. What is the value of y when x = 10? A) 1.5 B) 2.2 C) 37

xz_007 [3.2K]

Answer:

D) 65

Step-by-step explanation:

The formula for direct variation is

y = kx

where k is the constant of variation.

If we know y=32.5 and x=5, we can substitute in to calculate k

32.5 = k * 5

Divide each side by 5

32.5/5 = k

6.5 = k

So the equation is

y = 6.5k

Given x =10

y = 6.5*10

y = 65

3(x-6)^4+11=15 solve for x

Tamiku [17]

Answer:

x = 7.07 or 4.925

Step-by-step explanation:

3(x-6)^4+11=15

3(x-6)^4=15-11

(x-6)^4=4/3

x-6 = + $\sqrt[4]{4/3}$ or - $\sqrt[4]{4/3}$

x= + $\sqrt[4]{4/3}$ +6 or - $\sqrt[4]{4/3}$ +6

x = 7.07 or 4.925
