Answer:
The expression for the change received = $20 - 3 J
Step-by-step explanation:
The cost of 1 juice bottle = $3
Let us assume the number of juice bottles bought = J
The amount of bill paid = $20
Now, the cost of J juice bottles = J x ( Coat of 1 juice bottle)
= J x ( $3) = 3J
Now, the Change Returned = $20 bill - The cost of J juice bottles
= $20 - 3 J
or, Change Returned = $20 - 3 J
Hence, the expression for the change received = $20 - 3 J
Answer: x=5
Step-by-step explanation:
2(3x−6)=12+6
Step 1: Simplify both sides of the equation.
2(3x−6)=12+6
(2)(3x)+(2)(−6)=12+6(Distribute)
6x+−12=12+6
6x−12=(12+6)(Combine Like Terms)
6x−12=18
6x−12=18
Step 2: Add 12 to both sides.
6x−12+12=18+12
6x=30
Step 3: Divide both sides by 6.
6x
6

x=5
Answer:
x=5
Answer:
I got 17.
Step-by-step explanation:
Because it takes 4 days to make 20 small frames, it takes 8 days to make 40. And because it takes 3 days to make 21 frames, and 21 multiplied by 3 is 63 (one less than 64), it would take 9 days (3 times the amount for 21) to make 64 large frames. In all, it would take APPROXIMATELY 17 days (9 +8 is 17)
Answer:
f'(x) = 2x +
Step-by-step explanation:
differentiate using the power rule
( a ) = na
Given
f(x) = x² - + 9 = x² - 4 + 9 , then
f'(x) = 2x + 12 = 2x +

Hi! :)
The graph shows f(x) = [1/2]^x and its translation, g(x). Which describes the translation of f(x) to g(x)?
Translation of four units up! The f(x) function cannot possibly be f(x)=1/2, though, because that would be a horizontal line through y = 1/2 and that function is clearly not a horizontal line. So whatever f(x) is really, add 4 to the tail end of it to show its translation!
