The two angles shown ( 134 and X) make a straight line.
A straight line equals 180 degrees.
To find X subtract 134 from 180.
X = 180 - 134
x = 46
Answer:
check my explanation
Step-by-step explanation:
yes it is c.
by adding the ones on screen
it is option C
Square D because 2/8 are not shaded. 2/8=1/4 and 1/4=25%
The answer is y = -1/5x + 5
Perpendicular means the opposite reciprocal of the slope. The reciprocal of 5 would be 1/5. The opposite sign would be negative, so -1/5.
The equation that you use is y - y1 = m(x - x1)
The point is (-15,8).
x1 = -15
y1= 8
m= -1/5
y - 8 = -1/5(x - (-15)).
The 15 becomes positive.
y - 8 = -1/5(x+15)
Distribute
y - 8 = -1/5x - 3
Add 8 to both sides
y = -1/5x + 5
Answer:
f-1(x) = (x+4) / 2
Step-by-step explanation:
given f(x) = 2x – 4
let y = f(x) and rearrange to express x in terms of y
y = 2x – 4 (add 4 to each side)
y + 4 = 2x (divide both sides by 2)
(y+4) / 2 = x (rearrange)
x = (y+4) / 2
f-1(y) = (y+4) / 2
hence
f-1(x) = (x+4) / 2
