The chapter 7 test will have 20-30 questions on it. Novanet!
Answer:
19xy + 16z
Step-by-step explanation:
combine like terms
7xy +1 2xy= 19xy
8z - 2z + 10z = 16z

D it is d my guy you have fun with that
Easiest way is if you substitute each point (x,y) into each set of equations and both points work for both equations in the system of equations, then it is the correct answer
Otherwise substitute one equation for y in the other equation:
2x + 6 = x^2 + 5x + 6
-2x - 6. -2x -6
0 = x^2 + 3x. Factor
0 = x (x + 3)
Solve: x = 0. x + 3 = 0. ——> x = -3. Substitute into one original equation to get y value for
y = 2x + 6.
y = 2(0) + 6. y = 2(-3) + 6
y = 6. y = -6 + 6 —-> y = 0
(0 , 6) And. (-3 , 0)
A goes between -1 and -1/2
