Find equation where line passes through (7,8) and perpendicular to line y=8

1 answer:

5 0

Since in y=8, the slope is 0 (because there is no x) and b is 8 in y=mx+b, we know that the perpendicular line is x=(something) because the perpendicular lines of y=<number> are x=<number> due to that y=<number> equations are strictly horizontal while x=<number> equations are strictly vertical. Since we know that x=<number> has to pass through (7, 8), x =7

The perimeter of the square kitchen floor measures 48 feet. What is the area of the kitchen floor? A. 32 feet B. 96 square feet

exis [7]

Answer:

C. 144 square feet

Step-by-step explanation:

step 1

we know that

The perimeter of a square is given by the formula

$P=4a$

where

P is the perimeter

a is the length side of the square

we have

$p=48\ ft$

substitute in the formula

$48=4a$

solve for a

divide both sides by 4

$a=12\ ft$

step 2

Find the area

The area of a square is given by the formula

$A=a^2$

we have

$a=12\ ft$

substitute

$A=12^2=144\ ft^2$

Write a linear equation in slope- intercept form given 2x +5y =35

prohojiy [21]

Answer:

(0,−7)

Explanation:

To find the y-intercept of an equation, set x equal to 0 and solve: In the case of 2x−5y=35, let's replace all instances of x in the equation with 0 and solve for y: 2(0)−5y=35−5y=35−5y−5=35−5

y=−7

Thus, the y-intercept is at (x y)=

(0,−7).
