Answer:
f(x)=-3/2x+1
Step-by-step explanation:
y=mx+b
m=slope
b=y intercept
y=f(x)
The answer is 78 because when you add all the numbers it equals 780 and you need to divide the end sum by the amount of numbers added to get it. So in the end there were 10 numbers added to equal 780 so 780\10 equals 78
we are given that
two triangles are similar
so, the ratio of their sides must be same
we get

now, we can solve for x
step-1: Cross multiply both sides

step-2: Simplify left side

step-3: Subtract both sides by 2x


step-4: Divide both sides by 4

so,

Answer:
The correct answer is option A.120
Step-by-step explanation:
Let's start by analyzing the information they have given us.
We know that the stereo has a list price of $ 150, but at the time of payment, we are told that it has a 20% discount.
Now we must find out what the discount was applied to know the final price of the stereo.
One way to calculate the percentage would be multiplying 150 by 0.20
150.0.20 = 30
The discount applied is $ 30, so now we just have to subtract that amount from the original price:
150-30 = 120
Therefore, the correct answer is option A.
