Answer:
x = 4,
x = -2
Step-by-step explanation:
( x - 4 ) ( x + 2 ) = 0
Find out when the equation is 0,
When x = 4,
substitute in 4 for x,
( 4 - 4 ) ( 4 + 2 ) = 0
(0) ( 6) = 0 (any number multiplied by 0 is 0).
When x = -2
Substitue in -2 for x,
( -2 - 4 ) ( -2 + 2 ) = 0
(-6) (0) = 0 (again, any number multiplied by 0 is 0).
Replace x with 5, and evaluate the expression.
Remember to follow the correct order of operations.
100 - 15x =
= 100 - 15 * 5
= 100 - 75
= 25
Answer:
$84.75
Step-by-step explanation:
Given that she earns $9.75 per hour plus 10% of the parking fees that are collected, her income is of 2 folds; an hourly rate and an amount collected based rate.
If the shift is for 5 hours, her income based on
Hourly rate = 5 * $9.75
= $48.75
The amount collected based rate
= 10% * $360
= 10/100 * $360
= $36
Her total earnings will be
= $48.75 + $36
= $84.75
We are asked to write an expression that uses partial products to multiply 8 and 64. In this case, we can break 8 into 2 x4 and 64 into 8x8. In this case, multiplying these factors equal to 512. Any factors will do actually since it will yield the same product
