Answer:
B = 115
Step-by-step explanation:
Since A and B are supplementary, they add up to 180 degrees.
Thus, 65 + B = 180, and B = 115
Answer:
1. Missing the point - unanswerable
2. A and C
3. A
Step-by-step explanation:
Recall the slope of a line is parallel if the same slope and perpendicular if it is the negative reciprocal.
For number 1, each equation has the same slope as the function and will be parallel. Without the point, you cannot determine which one.
For number 2, find an equation that has slope -5/2. Both A and C have this property when converted to slope intercept form.
5x+2y=4 5x+2y = -3
2y=4-5x 2y= -3-5x
y=2-5/2 x y=-3/2 -5/2 x
For number 3, the slope will be the same as the equation for parallel. Convert the equation 4x-5y=-1 to find the slope.
4x-5y=-1
-5y = -1-4x
y=1/5 + 4/5 x
A is the solution.
You are correct. the slope of the line is 6/5 and the y-intercept is 2
