Answer:
x = 6
Step-by-step explanation:
An inverse variation is
xy = k where k is the constant of variation
8*9 = k
72 = k
xy = k
Let y = 12
x*12 = 72
Divide each side by 12
12x/12 =72/12
x = 6
Let m be the slope:
m=(y₂-y₁)/(x₂-x₁)
solve for c:
1/6=(9-c)/(1-7)
1/6=(9-c)/-6
-1=9-c
-10=-c
c=10
Answer: x = 22
Step-by-step explanation:
We must isolate the x by itself.
We need to add 5 to both sides of the equation so it cancel out from the side with x.
So x = 22
9514 1404 393
Answer:
26.4% decrease
Step-by-step explanation:
The amount of change is ...
2500 -1840 = -660
As a percentage of the original price, that is ...
-660/2500 × 100% = -26.4% . . . . . negative change = decrease
The decrease is 26.4%.
Answer:
B = 5 and F = 5
Step-by-step explanation:
Step 1: B = 5 because 350(5) = 1750
Step 2: F = 5 because 525(5) = 2625
Step 3: 2625 + 1750 = 4375
