Using Pythag,
= Missing side length.
Answer:
m=-3
Step-by-step explanation:
first multiply every thing out
3-18-4m=m
simplify
-15-4m=m
get all m's on one side
-15=5m
divide both sides by 5 to isolate m
-3=m

Answer:
$8.75
Step-by-step explanation:
25 × 0.65 =16.25
25 -16.25=8.75
Answer:
Step-by-step explanation:
For the line ax+by=c, solving for y gives ...
y = (-a/b)x +c/b
The slope in this slope-intercept form is the coefficient of x, -a/b. The y-intercept is c/b.
a) For the first line, the slope is ...
-a/b = -(-2)/3 = 2/3
__
b) For the second line, the slope is ...
-a/b = -4/1 = -4
__
c) The y-intercept of the first line is ...
c/b = 6/3 = 2
__
d) The y-intercept of the second line is ...
c/b = 12/1 = 12
__
e) The slopes of the lines are different, so there is one (1) solution.
