A division problem is -64 divided by -4 which equals 16 since 16 points was deducted from 100 points
Answer:
b
Step-by-step explanation:
I believe its b, because1.5 is 10 times 0.15
and 6.3 is 10 times 0.63
Answer:
C.g(x) = 5x²
Step-by-step explanation:
To find the equation for the function g(x), use the format for a quadratic equation. Without any up/down and left/right shifts, the form is y = ax².
Substituting "x" and "y" into the equation tells you if a point is on the graph.
"a" tells you the vertical stretch (greater than 1) or compression (greater than 0, less than 1).
In f(x) = x², a = 1 even though it's not written.
<u>Use the point (1, 5) on g(x) and substitute it</u> into the form for a quadratic function. Remember points are (x, y), so x = 1 and y = 5.
g(x) = ax²
y = ax² In function notation, g(x) replaces the "y". Switch it back to "y".
5 = a(1)² Substitute x = 1 and y = 5
5 = a(1) Solve the exponent first. (1)² = 1
5 = a When you multiply "a" by 1, the answer is just "a".
a = 5 Solved for "a". Put variable on left side for standard formatting.
With the quadratic form, substitute "a" into g(x).
y = ax²
g(x) = 5x²
Answer:
Step-by-step explanation:
if S=2*Π*r*h
h=S/(2*Π*r)
Given equation y=7x+25.
where x represents number of people being served and y represetns number of minutes it takes to prepare a meal.
Number of people can be taken for x variable are 1,2,3,4...
From the given equation if we plug x=0, it gives y=7(0)+25= 0+25=25.
So, fix number of minutes is 25 minutes to prepare a meal.
If we take x=1, that means we are taking 1 extra person and if we plug x=1 in original function, we get y=7(1)+25= 7+25.
So, it is taking 7 extra minute to prepare a meal.
Let us check by adding one more person. For that we need to take 1+1=2 number of person.
On plugging x=2, we get y=7(2) +25 = 14+25 = 7+7+25.
So every time if we add extra person, the time increase by 7 minutes to prepare a meal.
Therefore, Option "C) For every extra person served, the time it takes to prepare a meal increases by 7 minutes." is correct option.
