The answer is -14. Since it says to find h(-8) that means that x = -8 so then plug in the values and solve.

Answer:

The equation in point-slope is $\mathbf{y+5=3(x-6)}$

Step-by-step explanation:

We need to write the point-slope form of the equation of the line passing through the point (6,-5) and perpendicular to the line $y=-\frac{1}{3}x+4$

The general form of point-slope is; $y-y_1=m(x-x_1)$

where m is slope and $(x_1,y_1)$ is the point

We need to calculate slope.

We are given equation of line $y=-\frac{1}{3}x+4$ that is perpendicular to the required line.

The equation is given in slope-intercept form $y=mx+b$ where m is slope.

Comparing both equations we get m= -1/3

But we know that when lines are perpendicular their slopes are opposite reciprocal of each other i.e $m=-\frac{1}{m}$

So, slope of required line is m = 3 (opposite reciprocal of -1/3)

Now, the equation in point-slope form having slope m=3 and point (6,-5) is

$y-y_1=m(x-x_1)\\y-(-5)=3(x-6)\\y+5=3(x-6)$

So, The equation in point-slope is $\mathbf{y+5=3(x-6)}$

Name the property of real numbers illustrated by the equation -3(x + 4) = -3x -12

vivado [14]

Answer:

Distributive Property

Step-by-step explanation:

They distributed the -3 to x and 4. In this case, to distribute the -3, you multiply it to each term.

-3 × x = -3x.

-3 × 4 = -12.

-3x - 12

Tina has a rectangular planter box. She decides that she needs more planting space so she triples the length, doubles the width

kirill [66]

Answer:

Step-by-step explanation:

The volume is proportional to length, so tripling the length multiplies the volume by 3.

The volume is proportional to width, so doubling the width multiplies the volume by 2.

Tina's new planter box is 3×2 = 6 times the volume of the original.
