Answer:
y=9x-17; x=17/9 or x=1 8/9 or x=1.8
y=x+23; x= -23
Step-by-step explanation:
y=9x-17
0=9x-17 (Move variables to the left-hand side and change its sign)
-9x=-17 (Divide both sides of the equation by -9)
x=17/9, x=1 8/9, or x=1.8
y=x+23
0=x+23 (To find x-intercept/zero, substitute y=0)
-x=23 (Move variable to the left-hand side and change its sign)
x= -23 (Change the signs on both sides of the equation)
x= -23
Answer:
x = 5
y = 28
the expressions both equal y so they are equal to each other. so you right the equation as
9x - 17 = x + 23
then you subtract x from both sides
and then add 17 to both sides
the final step is to divide 8 on both sides and that gives you the answer x = 5. then you plug that back into the problem so...
y = 5 +23
so y = 28.
hope this helped!
