The circumference is 9 or approximately 28.26.
Let y = 0 to find the x-intercept(s).
0 = 45 − 4x
*Then subtract 45 from both sides*
-45 = -4x
*Next, DIVIDE both sides by -4*
-45
—— = x
-4
*NEXT, realize that TWO NEGATIVES MAKE A POSITIVE *
45. 4
——— = x {FLIP} x=——-
4. 45.
y-Intercept
Let x = 0 to find the y-intercept(s).
y = 45 −4(0)
NEXT, SIMPLIFY:
y=45
(8/4) = (10/x)
8x = 4 x 10
8x= 40
x = 40/8
x=5
It will take 5 hours.
C, as they are on the same plane, (it is uncommon to find non co-planar lines)
D, as that symbol means parallel
A is untrue as they are on the same plane
B is untrue as that symbol means perpendicular
E is untrue as perpendicular means the two lines intersect and form 90 degree angles
F is untrue as parallel lines never intersect
<span>5(x - 2) + 2x
= 5x - 10 + 2x
= 7x -10
