Finding the zeros is just factoring the equation. It is also where the parabola crosses the x- axis.
First you need to find two numbers that mutliply to give you -21 and add to give you 4 then you put it into this form:
(x +7)(x-3) set each part equal to zero
x+7=0 and x-3=0 you get:
x=-7 and x=3 your zeros
Answer:
c=y-3x^2-18x
axis of symmetry:
X=-3
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
add 5 to 13 then divide 9 by that number and that is what x equals
Type A: $20.20 ÷ 10 gal = $2.02 per gal
Type B: $$26.04 ÷ 12 gal = $2.17 per gal
Type C: $ 28.14 ÷ 14 gal = $2.01 per gal
Type D: $30.45 ÷ 15 gal = $2.03 per gal
Type B costs less per gallon.
Hope this helps!!
It would be: 8 - (1 1/4 + 2 3/8)
8 - (5/4 + 19/8)
8-29/8
64-29/8
35/8 inches OR 4.375 is your answer
