Answer: 
.
Step-by-step explanation:
If a line passing through two points, then
Endpoints of segment MN have coordinates (0, 0) and (5, 1).
Slope of MN 
The endpoints of segment AB have coordinates 
and 
.
.
Slope of AB 
Product of slopes of two perpendicular segments is -1.
Slope of MN × Slope of AB = -1
Therefore, the value of k is .
Answer:
D
Step-by-step explanation:
The letter D includes a curved line, unlike the letters X, M, and F.
X-6y=6 slope: 1/6 y-intercept (0,1)
X= 0,6 y= -1, 0
X+3y+12=0 slope: 1/3
Y-intercept (0,4) x= -12, 0 Y= 0,4
8a-9b= 9/8 slope (0 ,7/8) x= -1,1 Y= -1/4,2
3a+b=7 1/3 (0,7/3) x= 4,7 Y=1,0
The line cuts the X axis at 
and is parallel to the Y axis.
Thus the equation of the line is $\boxed{x=3}$
Company A charges a $125 annual fee plus $7 per hour car share fee.
Company B charges $110 plus $10 per hour. The minimum number of hours that a car share needs to be used per year to make company A a better deal is 6 hours.
A: y=125+7 x
B: y=110+10 x
for A to be a better deal than B, 125+7 x<110+10 x has to be true
subtract 7x from both sides and subtract 110 from both sides of the inequality: 15<3 x
divide by 3: 5<x
so x has to be greater than 5 , im pretty sure it's 6 hours but it might also be 5 depending on how it's taught for you.
Equations are not always balanced on both sides using a "equal to" symbol in mathematics. Sometimes it can be about a "not equal to" relationship, meaning that something is superior to or inferior to another. In mathematics, an inequality is a relationship between two numbers or other mathematical expressions that results in an unequal comparison. Inequalities are the name given to certain algebraic mathematical expressions.
