Mr. brown is creating examples of systems of equations. he
completes the steps to find the solution of the equation
below.
5x +2y=8
- 4(1.25 x + 0.5 y = 2)
5x +2y=8
- 5 x - 4y = -8
0 = 0

a(4,4)
b (0,0)
c. no solution
d. infinitely many solutions

Step-by-step explanation:

The given system of equation is

Mr. Brown multiplies the second equation by -4 and then he sums them up

This result indicates that the sysmte has infinitely many solutions, because both equations represent the same line. Or you can see it as the lines are one on the other.

Therefore, the right answer here is D.

n

step-by-step explanation:

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
