Answer:
Step-by-step explanation:
So, it's x*x+x*-3+-4*x+3*-3
That simplifies to x^2 - 7x + 12
Answer:
y= x^2 + 6
Step-by-step explanation:
y= x2 + 6 (which should be written as y= x^2 + 6) has the form y - k = a(x - h)^2. For y= x^2 + 6, h = 0 and k = 6. Thus the vertex is (0, 6)
You can solve an easy equation in your head by using the multiplication table.
Answer:
Step-by-step explanation:
The mean (or average) of a set of numbers can be found with the following formula:

For this problem, we have five numbers, so we add them together and divide by 5:




= -7 Multiply both sides by 10
x = -70
C. x = -70
