The given function is
f(x) = 4x - 3/2
where
f(x) = number of assignments completed
x = number of weeks required to complete the assignments
We want to find f⁻¹ (30) as an estimate of the number of weeks required to complete 30 assignments.
The procedure is as follows:
1. Set y = f(x)
y = 4x - 3/2
2. Exchange x and y
x = 4y - 3/2
3. Solve for y
4y = x + 3/2
y = (x +3/2)/4
4. Set y equal to f⁻¹ (x)
f⁻¹ (x) = (x + 3/2)/4
5. Find f⁻¹ (30)
f⁻¹ (30) = (30 + 3/2)/4 = 63/8 = 8 (approxmately)
Answer:
Pedro needs about 8 weeks to complete 30 assignments.
Answer:
3/8 tablespoons
Step-by-step explanation:
When we add fractions, we have to make each fraction a common denominator.
So we get 1/4 into 2/8 and we have 1/8
So we add and get 3/8
I think its C HOPEFULY THISIS RIGHT GOOD LUCK!!!!!!!!!!!!!!!!!!!1
.75 because the more numbers after the decimal point the smaller it gets
Answer:
![18\ pieces](https://tex.z-dn.net/?f=18%5C%20pieces)
Step-by-step explanation:
step 1
Divide each large candy bar into thirds
so
![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Now for each large candy bar you have 3 pieces of ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
step 2
Find the total number of candy bars pieces by proportion
![\frac{1}{3}\frac{bar}{pieces} =\frac{6}{x}\frac{bar}{pieces}\\ \\x=6*3\\ \\x=18\ pieces](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%5Cfrac%7Bbar%7D%7Bpieces%7D%20%3D%5Cfrac%7B6%7D%7Bx%7D%5Cfrac%7Bbar%7D%7Bpieces%7D%5C%5C%20%5C%5Cx%3D6%2A3%5C%5C%20%5C%5Cx%3D18%5C%20pieces)
