Answer:
-86
Step-by-step explanation:
simplify each equation as much as possible
f(x)= 4x(2+9) add
4x(11) multiply
f(x)=44x
substitute given numbers into each equation
44(-2)=-88 3(4)-14= 12-14=-2
combine equations
-88-(-2)= -86 add since you are subtracting a negative number
Answer:
6 hours. ( I DID IT USING PROPORTIONS!)
Step-by-step explanation:
houses/hours
130/2.5= 312/x
(cross multiply)
130x = 780
130x/130 = 780/ 130 (divide each by 130)
6 = h
The y-intercept (where the line hits the y-axis) will move from (0, 1/2) to (0, -2)
Answer:
91
Step-by-step explanation:
I used a calculator and if you add 76, 93, 89, 71 to 91 it equals 420 and if you divide that by 5 it is 84.
Hope this helps!
In pretty sure it’s D , making each side equal to 6
