Answer:
Step-by-step explanation:
These are physical measurements, which must be zero or greater. These restrictions are the reason for your having a total of four inequalities.
F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
I made the denominators the same
8/16=1/2
I subtracted 1/16 from 8/16
8/16 - 1/16+ 7/16
Yahir has 7/16 of a gallon of milk left
(10,84)(20,159)
slope(m) = (159 - 84) / (20 - 10) = 75/10 = 7.5
y = mx + b
slope(m) = 7.5
use either of ur points...(10,84)...x = 10 and y = 84
now we sub and solve for b, the y int
84 = 7.5(10) + b
84 = 75 + b
84 - 75 = b
9 = b
so ur equation is : y = 7.5x + 9...with each shirt costing $ 7.50 and the one-time set up fee costing $ 9.00...with y being the total cost and x being the number of shirts bought
for 30 shirts......x = 30
y = 7.5(30) + 9
y = 225 + 9
y = 234 <== cost of an order of 30 shirts
Answer:
the slopes are 1=2 2=1 3=-6 4=-1 5=5 6=undefined 7=0 8=0 9=-4 10=undefined
