Answer:
A coefficient is a number in front of a variable. For example, in the expression x 2-10x+25, the coefficient of the x 2 is 1 and the coefficient of the x is -10. The third term, 25, is called a constant.
Step-by-step explanation:
Answer:
bni already took this it was correct
Step-by-step explanation:
Remember you can do anything to an equaiton as long as you do it to both sides
7x-4=5x+15
minus 5x both sides
2x-4=15
add 4 both sides
2x=19
divide by 2
x=19/2
Answer:
The vertex is the point 
Step-by-step explanation:
we have

we know ow that
The equation of a vertical parabola into vertex form is equal to

where
(h,k) is the vertex of the parabola
Convert the equation into vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares

therefore
the vertex is the point
