Question 3
a pair of equations is shown below:
y = 7x − 8
y = 5x − 2
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)

Which equation results from adding the equations in this system? x+6y=9 and -x+2y=-15

Give the functions f(x) = |x + 2| - 3, what is the domain? a,b,c, or d all real numbers x > 2 x < -2 all real numbers and x cannot equal to 2

Worth 100 points need the answers asap first row -x^2 2x^2 (x/2)^2 x^2 x is less than 2 x is greater than 2 x is less than or equal to 2 x is greater than or equal to 2 second row -5 -5/2 4 5 •2 is less than x& x is less than 4 •2 is less than or equal to x & x is less than or equal to 4 •2 is less than or equal to x& x is less than 4 •2 is less than x& x is less than or equal to 4
