- You buy a bunch of 12 bananas and pay $6 and want to know how much each banana costs.
- You pull into a gas station where the gas is $2.50 a gallon. You want to know how much you would need to fill up your 35 gallon tank.
- You drove 300 miles to visit your cousin in another state. It takes you 4 hours. You want to know how many miles you drove per hour.
f(x) = 6x
To find the inverse, replace f(x) with Y:
y = 6x
Now switch the variables:
x = 6y
Solve for Y by dividing both sides by 6:
y = x/6
Now replace y with f^-1 (x):
f^-1 (x) = x/6
Answer:
angle j = 90
angle k = 29
angle L = 61
Step-by-step explanation:
180 = 90 + (4x-19) + (5x+1)
90 = 9x - 18
108 = 9x
x = 12
We know that the sum of measures of internal angles in each quadrangle is 360°.
Look at the picture.
Therefore we have:
Answer: θ = 141 deg.
