Answer:
159.75
Step-by-step explanation:
23.50×5=117.5
117.5+42.25=159.75
1) Line should be parallel to y = 3x+6, so slope of this line should be =3.
y=mx +b
y=3x +b
Now we have to find b (y-intercept), using the point (-10, 2.5).
2.5 = 3*(-10)+b
b=2.5+30=32.5
y=3x + 32.5
2) The line should be perpendicular to y = -4x -2, so its slope is going to be negative reciprocal m= 1/4.
Now we have to find b (y-intercept), using the point (-16, -11).
y=(1/4)x +b
-11=(1/4)*(-16) + b
-11 = -4 +b
b = -7
y=(1/4)x - 7
The one that makes the most sense is C
24 ^ 2/3 = (8 ^ 2/3) * (3 ^ 2/3)
cancle out the 8^2/3 and you get (3 ^ 2/3) * (3 ^ 4/3) = 3^2 = 9
