Only the first one works
y = 3(-1)-2 = -5
y = -(0) -6 = -6 not -2
This is a substitution problem...
Answer:
THE answers to both questions are A
Step-by-step explanation:
Answer:
-129
Step-by-step explanation:
2x+5=0
x=-5/2 [By the remainder theorem]
f(-5/2)=8(-5/2)^3+4(-5/2)^2+13(-5/2)+3
=-125+25-65/2+3
=-129.
Answer:
x = 12, y=7
x=30, y=25
x=15, y=10
Step-by-step explanation:
We have : y = x - 5
x = 12 then y = 7, y = 12 - 5 = 7
x = 30 25 = x - 5, x = 25 + 5 = 30
x = 15, y = 15 - 5 = 10, y = 10
