Answer:
x = - 16 , x = 24
Step-by-step explanation:
Given
f(x) = 0.5| x - 4 | - 3 and f(x) = 7, then equating gives
0.5|x - 4 | - 3 = 7 ( add 3 to both sides )
0.5| x - 4 | = 10 ( divide both sides by 0.5 )
| x - 4 | = 20
The expression inside the absolute value can be positive or negative, that is
x - 4 = 20 or - (x - 4) = 20
solving both
x - 4 = 20 ( add 4 to both sides )
x = 24
or
- (x - 4) = 20
- x + 4 = 20 ( subtract 4 from both sides )
- x = 16 ( multiply both sides by - 1 )
x = - 16
Answer: C, 2 3/5
Step-by-step explanation:
- Let's start by making these fractions easily subtractable
7 1/5 = 6 6/5 (1 is equal to 5/5 so we take that from the 7 and add it to the fraction)
4 3/5 remains the same because this is what we are subtracting
7 1/5 - 4 3/5 will be subsituted for 6 6/5 - 4 3/5=? because it's equivilant
I like to break this into two parts to make it less complicated, fraction then number
- Fraction: 6/5-3/5=3/5
- Whole Number 6-4=2
- Combine back into a mixed number
This will give you the proper fraction for the result of your equation
2+3/5=2 3/5
2 3/5
Answer: 0
