X=-0.6 or -2/3

Substitute y for 0

multiply both sides of the equation by 2
Move the variable to the left-hand side and change its sign

Divide both sides of the equation by -3

Perpendicular = opposite sign and reciprocal slope
Y = 3/2x + 1
The slope is 3/2, opposite sign = -3/2 now reciprocal = -2/3
Y = -2/3x + b
Plug in the point (6,-2)
-2 = -2/3(6) + b
-2 = -12/3 + b
-2 = -4 + b, b =2
Solution: y = -2/3x + 2

Stels [109]

Answer:

y = -7/6x +7

Step-by-step explanation:

To get y by itself, divide by its coefficient.

(42 -7x)/6 = y

We can simplify this and swap sides to get ...

y = -7/6x +7

A new parabola, g(x), is translated from f(x) using the translation T(-3, 7).

andriy [413]

Answer:

We can predict the vertex point of $g(x)$ by vectorial sum, which is equal to $V_{G}(x,y) = (h - 3, k + 7)$ .

Step-by-step explanation:

The vertex of $g(x)$ is equal to the vectorial sum of the vertex of $f(x)$ and the translation vector:

$V_{G}(x,y) = V_{F}(x,y) + T(x,y)$ (1)

Where $T(x,y)$ is the translation vector.

If we know that $V_{F} (x,y) = (h,k)$ and $T(x,y) = (-3, 7)$ , then the formula for the vertex of $g(x)$ is:

$V_{G}(x,y) = (h,k) +(-3, 7)$

$V_{G}(x,y) = (h - 3, k + 7)$

If a rectangular prism with a length of 12 feet and a width of 9 feet has a surface area of 930 square feet find its height

WINSTONCH [101]

Answer:

The height is 17 ft

Step-by-step explanation:

The surface area of a rectangular prism is

SA = 2(LW +WH + LH)

where L = length, W = width, and H = height

We know SA = 930, L = 12, and W = 9

930 = 2(12*9 +9H + 12H)

Divide each side by 2

930/2 = 2/2(12*9 +9H + 12H)

465 = (12*9 +9H + 12H)

Combine like terms

465 = 84+21H

Subtract 84 from each side

465-84 = 84-84+21H

357 = 21H

Divide by 21

357/21=21H/21

17 = H

The height is 17 ft
