65.8 + 13.4 = 79 .2. So the answer is c
Y = 2x - 17, comparing to y = mx + c, slope m = 2.
If perpendicular, the new slope would be -1/2, that is the negative reciprocal of 2.
And passing through (-8 , 1).
using y = mx + c, and x = -8, y = 1, m = -1/2
1 = -1/2*-8 + c
1 = 4 + c
1 - 4 = c
c = -3
y = mx + c, substituting m = -1/2, and c = -3, y = -(1/2)x - 3.
Option C.
Answer:
0.25
Step-by-step explanation:
5x-3 > 15x-11/2
5x-15x > 3-11/2
-10x > -2.5
x > -2.5/-10
x > 0.25
Given data:
The given distance Jadwiga runs in a day is 875 m.
The expression for the given statement is,
1d=875 m
Multiply the above expression by 7 on both sides.
7(1 day)=7(875 m)
=6,125 m
=6.125 km
Thus, Jadwiga covered 6.125 km in 7 days.
