Answer:

9x^2y^2

Step-by-step explanation:

Ok so to find the area of a square we have to square the side length. So 3xy*3xy = 9x^2y^2 because 3*3=9, x*x=x^2, and y*y=y^2.

Which equation describes a line that passes through (-5,-8) and is perpendicular to y= 5/4x + 10
lara31 [8.8K]
Answer: y = -4/5x - 12

1. First find slope. Since you are trying to find a line perpendicular to y = 5/4x + 10, the slope would be the negative reciprocal of 5/4x.

slope = - 4/5x

2. plug in (-5,-8) and the slope of -4/5 to the point slope form equation
(y-y2) = slope (x-x2)

= y+8=-4/5(x+5)

3. solve and simply y+8=-4/5(x+5)

y = -4/5x - 12 is your answer

Which of the following describes graphing y ≥ |x| + 4?
kolbaska11 [484]

Answer:

Translate  y=\left|x\right| up 4 units and shade inside the V

Step-by-step explanation:

we know that

The function y=\left|x\right| has the vertex at point (0,0)

The function y=\left|x\right|+4 has the vertex at point (0,4)

so

the rule of the translation is

(x,y)------> (x,y+4)

That means

The translation is 4 units up

The solution of the inequality  y\geq\left|x\right|+4

is the shaded area inside the V

see the attached figure to better understand the problem

therefore

the answer is

Translate  y=\left|x\right| up 4 units and shade inside the V
