X = 12400
20/100 = 1/5
2480 x 5 = 12400
In a graph, it is when two variables move in an upwards direction.
Answer:14-1/3 if that makes sense to you
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
we have f(x) = -(x-7) + 3
and we want to find f(4)
essentially, f(4) means that the input is 4 and to find the output we plug in the value of the input where ever x is and evaluate.
So for f(x) = -(x-7) + 3
To find f(4) we replace all x's with 4
f(4) = -(4-7) + 3
we now evaluate
==> subtract 7 from 4
f(4) = -(-3) + 3
==> apply two negative rule ( basically if there are two negative signs they cancel out and the number turn positive )
f(4) = 3 + 3
==> add 3 and 3
f(4) = 6
Answer:
x = 5
Step-by-step explanation:
y = -4x + 5 4x + y = 10
substitute the y in the second equation with
(-4x +5).
4x + (-4x + 5) = 10 then add like terms.
x + 5 = 10 solve for x.
10 - 5 = 5 make sure to check your answer.
5 + 5 = 10
