Answer:
b
Step-by-step explanation:
5(0)-3(-4)=12 that simply's to 0+12=12
its no subtraction sign cause cant have a double negative

replace f(x) wih y
solve for x
replace x with f⁻¹(x) and y with x
so
f(x)=3x+5/7
replace
y=3x+5/7
solve for x
minnus 5/7 both sides
y-5/7=3x
divide both sides by 3

=x
replace with f⁻¹(x)
f⁻¹(x)=
<span>y = mx + b ; where m=slope of the line.
You want the slope to go downhill from left to right, that would mean that m = (-)...
so the answer is D</span>
First multiply the big numbers. 3*1.20= ($3.60) and 5*1.20= ($6)
Now the fractions, 1/12 would equal 10 cents. 5/12 + 1/12= 6/12 which would also equal (60 cents). 3.60+6.00+.60= $10.20
