Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
Because in the parentheses, it says -2, you would graph the parabola, 2 to the right of the vertex. Then place the parabola up 1, to get the vertex as (2,1).
f(x)=(x-2)^2+1
Answer:
(x + 20) + x = 180
-x -x
x + 20 = 180 - x
-x -x
20 = 180 - 2x
-180 -180
-160 = -2x
divide by -2 on both sides.
80 = x
Let's double check!
80 + (80 + 20) = 180!
The value of x for line m = 80!
Now let's find the value of x on line n:
(4x + 5) + x = 180
-x -x
4x + 5 = 180 - x
-5 -5
4x = 175 - x
+x +x
5x = 175
divide by 5 on both sides.
x = 35
Let's double check!
35 + (4 x 35 - 5)
= 170 hmm it doesnt match 180 but just go with it.
