Find the slope of the line that is perpendicular to y= -1/2x+11
Answer:
The slope is 2
Step-by-step explanation:
The sign changes and the slope will be be the reciprocal (flipped)
Answer:
2
Step-by-step explanation:
hi! to find the perpendicular slope, you have to flip the fraction to its reciprocal and use the opposite sign (- or +).
-1/2's reciprocal is -2, and its opposite sign is +, so the slope of the line that is perpendicular to this line is 2.

Write the equation of the line with the slope of 10 that goes through the point 8,-2 in point slope form
Answer:
y=10x+28
Step-by-step explanation:
y=10x+28
y=(10*-2)+28
y=-20+28
y=8
The linear equation of the line is y + 2 = 10(x - 8)
How to determine the line equation?The slope is given as:
m = 10
The point is given as:
(x1, y1) = (8, -2)
The equation in point slope form is calculated as;
y - y1 = m(x - x1)
So, we have:
y + 2 = 10(x - 8)
Hence, the linear equation of the line is y + 2 = 10(x - 8)

What is the difference in the steps you take to evaluate (-7)2 and -72 ? What is the
difference in the values?
Answer:
58
Step-by-step explanation:
because it is
Answer:
Sample Response:
To find (–7)2, the base –7 is multiplied by itself: (–7)(–7) = 49. To find –72, the base 7 is multiplied by itself: 7 • 7 = 49. The negative sign is then applied to get –49.
what is the answer to 8-5x=-37
Answer:
x=9
Step-by-step explanation:
Subtract 8 from both sides.
−5x=−37−8
Subtract 8 from −37 to get −45.
−5x=−45
Divide both sides by −5.
x= -45/-5
Divide −45 by −5 to get 9.
x=9
Answer:
9
Step-by-step explanation:
Step 1:
8 - 5x = - 37 Equation
Step 2:
8 = - 37 + 5x Add 5x on both sides
Step 3:
45 = 5x Add 37 on both sides
Step 4:
x = 45 ÷ 5 Divide
Answer:
x = 9

Ralph wants to build a rectangular deck with a predefined area of 66 feet squared. One side of the deck will be 5 feet longer than the other. To find the side lengths, he first writes the equation (x)(x+5)=66 and later simplifies (x-6)(x+11)=0 it to , where x is the length of the shorter side. Which of these are the side lengths, in feet, of the rectangular deck? Select all that apply
Answer:
The shorter side is 6 ft and the longer side is 11 ftStep-by-step explanation:
The options are not given, but we could solve and arrive at an answer
say the shorter side is x
and the longer side is x+5
we know that the area of a rectangle is given as
x*(x+5)=66
open the bracket
x^2+5x=66
x^2+5x-66=0
Find two factors of -66 whose sum equals the coefficient of the middle term, which is 5 .
the factors are 11 and -6
splitting the middle term using the two factors 11 and -6
x2 +11x - 6x - 66=0
x(x+11)-6(x+11)=0
(x-6)=0
x=6
(x+11)=0
x=-11
The shorter side is 6 ft and the longer side is 11 ft
