The erea of a concrete rectangular pathway is 350 m2 and its perimiter pathway is 90m. what is the length of the pathway

Let length = L m and width = W m. Then:-

LW = 350

2L + 2W = 90

from the above equation:-

L = (90 - 2W) / 2

Substituting for L in the first equation:-

W(90 - 2W) / 2 = 350

90W - 2W^2 = 700

2W^2 - 90W + 700 = 0

(2W - 70)(W - 10) = 0

W = 35 , 10

therefore L = 10, 35

Answer Length = 35m and width = 10 m

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
