Answer:
2x+7
Step-by-step explanation:
3x +(-x) = 3x - x, so it's 2x
12 + (-5) is the same situation, just being 12 - 5, so it's 7.
putting them together leaves you with 2x+7
The distributive property says that a(b+c)= ab+ac.
2(b+5)= 2*(b)+2*(5) =2b+10
Final answer: 2b+10
Answer:
The vertex is at (2,4)
Step-by-step explanation:
The parabola is given in the form
y = a(x-h)^2 +k
where (h,k) is the vertex
y=2(x-2)^2+4
The vertex is at (2,4)
