A pair of equations is shown below: y = 3x - 5
y = 6x - 8
Part A: Explain how you will solve the pair of equations by substitution or
elimination. Show all
the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the
two equations intersect? Explain your answer. (5 points)

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
