<span>8.7 = 3.5m - 2.5(5.4 - 6m
3.5m - 2.5(5.4 - 6m) = 8.7
18.5m - 13.5 = 8.7
18.5m - 13.5 + 13.5 = 8.7 + 13.5

Im sorry i can’t help you but you can use photomath and also Aaa HANGE
Answer:
Two straight lines with slopes m and m' are parallel when m = m'
Two straight lines with slopes m and m' are perpendicular when m × m' = - 1.
Step-by-step explanation:
Let us assume that the two non-vertical lines in the slope-intercept form are
y = mx + c ........... (1) and
y = m'x + c' ............ (2)
If those two lines are parallel then we can say the slope of them will be the same i.e. m = m'
Now, if given two straight lines (1) and (2) are perpendicular to each other and neither of them is parallel to the axes, then we can write m × m' = - 1. (Answer)
Answer:
The answer to your question is 7.8 mi
Step-by-step explanation:
Data
H (4,3)
G (10, 8)
Process
1.- Use the distance between to points formula to find the distance
dHG =
x1 = 4 y1 = 3
x2 = 10 y2 = 8
2.- Substitution
dHG =
3.- Simplification
dHG =
dHG =
dHG =
4.- Result
dHG = 7.8 mi
