Answer:
- y = -1/7x
- y = 2x -7
Step-by-step explanation:
1. The slope of the given line is the x-coefficient, 7. The slope of the perpendicular line is the negative reciprocal of this: -1/7. Since the line goes through the origin, the y-intercept is zero.
y = -1/7x
__
2. The first part of this problem is to find the solution to the given system of equations. We can substitute for x to do that:
3(5 -y)-2y = 10
15 -5y = 10 . . . simplify
-3 +y = -2 . . . . divide by -2
y = 1, x = 4 . . . add 3 to find y; subtract y from 5 to find x
__
The second part of this problem requires we note the slope of the parallel line. It is the x-coefficient, 2. The y-intercept can be found from ...
b = y -mx = 1 -2(4) = -7
So, the desired line in y=mx+b form is ...
y = 2x -7

Answer:
5^18
Step-by-step explanation:
Multiply 6 and 3 together.
Answer:
A and D both have a value of -4
Step-by-step explanation:
A. (-4) = -4
B. |-4| = positive value of what is inside = 4
C. |4|
= positive value of what is inside = 4
D. -|4| = -positive value of what is inside = -4
The two inside angles add up to the external angle's total. The m∠1 will be 69°. Option D is correct.
<h3>What is angle measurement?</h3>
An angle measure is the measurement of the angle created by two rays or arms at a shared vertex in geometry. A protractor is used to measure angles in degrees (°).
From the exterior angle property, the sum of the exterior angle is the sum of the two interior angles.
The m∠1 will be 69°.
Hence, option D is correct.
