Step-by-step explanation:
When x = -2 and y = 3,
10y + 2(3x + 2)
= 10(3) + 2[3(-2) + 2]
= 30 + 2(-4)
= 30 - 8
= 22.
Answer: 8x^4.5, 4x^3
Step-by-step explanation:
We want to get out x's together on the right side of the inequality.
So, subtract <em>x </em>from both sides to get 9 < 3x.
Now divide both sides by 3 and we get 3 < x.
I personally like to have my variables on the left so we can move the 3 to the left and the <em>x</em> to the right but if we do that, we have to switch the inequality sign.
So we can rewrite this as x > 3.
Answer:
First solve I will divide both sides by the coeeficient (the number attached to the vairable) -3. then I will have my answer of x = -4
