Answer:
lines 1 and 3
Step-by-step explanation:
y = 2 is a horizontal line parallel to the x- axis
x = - 4 is a vertical line parallel to the y- axis
Then these 2 lines are perpendicular to each other
y = 15x - 3 ( in the form y = mx + c ) with m = 15
y + 1 = - 5(x + 2) ( in the form y - b = m(x - a) with m = - 5
For the lines to be perpendicular the product of their slopes = - 1
However
15 × - 5 = - 75 ≠ - 1
The 2 lines 1 and 3 are perpendicular

Angelica needs to sell 20 TVs.
Steps:
Step 1: You divide 5,000 and 250.
5,000/250 = 20
Check: You multiply 250 and 20.
250 x 20 = 5,000
Number one: Just plot down on the number like the numbers you have. Just took the test for this.
Answer: 80.5
Step-by-step explanation:
Given that,
Base of Triangle = 23 ft
Height of Triangle = 7 ft
We know,
Area of Triangle
= 0.5 × Base × Height unit^2
=(0.5 × 23 × 7) ft^2
= 80.5
