Answer:
Step-by-step explanation:
2b^2 - 3b + 4a^2........a =-6 and b = 8
now we sub
2(8^2) - 3(8) + 4(-6^2)
2(64) - 24 + 4(36)
128 - 24 + 144
272 - 24

Answer:
x≤-2
Step-by-step explanation:
To solve the inequality, we have to add 1 on each side:
5x-1≤11
+1 +1
And then we get:
5x≤-10.
To find x, we have to divide each side by 5:
5x/5≤-10/5
After we do that, we get:
x≤-2.
Step-by-step explanation:
y= 1
when x=2
here
when x= 3
y=4
