Step-by-step explanation:
The mean is given as 7. That is the only information given, and it is not enough to determine the number of raisin in each scoop.
Suppose the total number of raisins was given, then the total number of raisins is easily given as (total number of raisins) ÷ (mean)
= (total number of raisins) ÷ 7
Answer:
x = 100
It is on a straight line and so, it equals to 180.
180 - 80 = 100
You have to create and equivalent EXPRESSION in the equation that have equal bases then solve for x
SO THE ANSWER IS 12<span />
Answer:
A) (-5, -34)
Step-by-step explanation:
f(x) = x^2 + 10x - 9
We complete the square to get the equation in vertex form
Take the coefficient of the x term and divide by 2 then square it. We add it and then subtract it not to change the value of the equation
f(x) = x^2 + 10x +(10/2)^2 - (10/2)^2 - 9
f(x) = x^2 +10x +25 -25 -9
f(x) = (x^2 +10x +25) -34
The term in parentheses simplified to (x+10/2) ^2
= (x+5)^2 -34
= (x - -5)^2 -34
This is in the form (x-h)^2 +k
The vertex is (h,k) h=-5 and k=-34
(-5,-34)

v : (7 - u)
