We have ax - bx = 1;
Then (a - b)x = 1;
If a - b is not 0, then x = 1 / (a-b);
-1 and 1 are opposites, not decimals, and not fractions. Please mark Brainliest!!!
They are actually asking for 1.5 and -2 so the answer will be coordinated at approximately half past 1 and on -2 which is located on the right lower quadrant
Answer:
56 hours
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
Let
x -----> the number of hours
y ----> the amount earned in dollars
This problem represent a proportional relationship between the variable x and the variable y
Find the value of the constant of proportionality k
For (3,27) ---->
For (9,81) ---->
For (21,189) ---->
The constant of proportionality k is 9
The linear equation is
For y=$500
substitute in the equation and solve for x
Divide by 9 both sides
