Answer:10
Step-by-step explanation:
9/5=18/x
90=9x
X=10
(5/8)+(2/5)=
so you need a common den so in this case its 40
so we multiply to get 40 like
(5/5)(5/8)+ (2/5)(8/8)=
25/40 + 16/ 40 = 41/40
Answer:
All of them except B
Step-by-step explanation:
Bisecting is splitting a line in half
Parallel lines never touch each other
Intersecting lines intersect
Corresponding lines are 2 parallel lines with a line that is going through them
Answer:
m = -1/3
Step-by-step explanation:
y = 3x-4
This is in slope intercept form
y = mx+b m is the slope and b is the y intercept
The slope is 3 and the y intercept is -4
We want the slope of a line that is perpendicular
Perpendicular lines have slopes that multiply to -1
Let m be the slope of the line that is perpendicular
3 * m = -1
Divide each side by 3
3m/3 = -1/3
m = -1/3
A line with an undefined slope would be vertical, meaning the x-coordinate will not change regardless of where the y-coordinate is.
Therefore, the equation would simply be x= -2
This is b/c x does not ever change (it is a vertical line)
while y could be any number on that line
