Answer:
x = 
Step-by-step explanation:
Distributive Property:
3 (x - 4) = 12x
3x - 12 = 12x
Combine like terms and isolate the variable:
3x - 12 = 12x
-12 = 9x
= x
x = 
Answer:
y=2x+6
Step-by-step explanation:
y=mx+b
your two point that are [-1, 4] with 1 as x and 4 as y
replace y with 4 then replace m with 2 then put your negative one in () it should look like this
4=2(-1)+b then do what in Parentheses
that will give you -2 then add 2 to 4 and that will give u 6
y=2x+6
Area= l * b
12= 5 * b
b = 12/ 5
b= 2.4 ft
Answer:
I believe the answer would be 323/40=$8.07/hr
Answer:
When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.
