Answer:
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to
where
a is a coefficient
x1 an x2 are the roots or x-intercepts
In this problem we have
substitute
with the y-intercept (0,-48) find the value of a
substitute
The equation is equal to
Answer: fx=3(x-8)(x+2) or answer C
Step-by-step explanation:
bc i said so
-7x + y = -22
-7*4 + y = -22
y = -22 + 28
y = 6
parenthesis, exponents, multiplication, division, addition, subtraction.
(14)/(7)(5)(-3)^2 solve exponent first and then the multiplication part (7x5)
(14)/(35)(9) 14 divided by 35 is .4
(.4)(9)=3.6 .4 multiplied by 9 is 3.6 <- that's the answer for 7
remember parenthesis first so we will do 6-1 first which is 5. after parenthesis, well do exponents. 5^2 is 25.
we will finish the big parenthesis which is the brackets, and 30-25=5. now it's 5 +5=10<- that is the answer for 9. Do I need to explain more/ if not i hope this helps you better understand this.
