Answer:

x = 1

Step-by-step explanation:

3(2) = $\sqrt{4^{2} + 20 x }$

6= $\sqrt{16+20 x}$

square both side

36 = 16 +20x

20 = 20x

Suppose that x and y vary inversely, and x = 2 when y = 9. Write the function that models the inverse variation

stiv31 [10]

Answer: 18/3 or 6

Step-by-step explanation:

y= x/k

[as y various inversaly with x]

y=9;x=2

k=yx=9×2

k=18

y= x/18

Which of the following describes the graph of y = StartRoot negative 4 x minus 36 EndRoot compared to the parent square root fun

RoseWind [281]

Answer:

stretched by a factor of 2, reflected over the y-axis, and translated 9 units left

Step-by-step explanation:

The given function is $y=\sqrt{-4x-36}$

We can rewrite this function by factoring -4 in the radicand to get:

$y=\sqrt{-4(x+9)}$

We further simplify the square root of 4 to get:

$y=2\sqrt{-(x+9)$

The parent function is $y=\sqrt{x}$

When we compare to the parent function, there is a stretch by a factor of 2, reflection over the y-axis, and translation 9 units left

The last option is correct

Answer:

87 degrees

Step-by-step explanation:

9x+6 + 7x-2 = 148

16x+4 = 148

16x = 144

x = 9

Plug into 9x+6

9(9)+6 = 87
