2x - y = 7

y = 2x - 7 this line has slope = 2

Perpendicular lines, slope is opposite and reciprocal so slope = -1/2

Answer

A . -1/2

2x - y = 7

Put this equation in slope intercept form, y = mx + b.

Solve for y by subtracting 2x from both sides.

- y = 7 - 2x

Divide both sides by -1.

y = -7 + 2x

---

Perpendicular lines have opposite reciprocal slopes, so flip the slope of the line and change the sign.

The slope of this line: y = -7 + 2x is 2, so find the reciprocal and add a negative sign.

2 becomes -1/2, so your answer is:

A) -1/2

Determine whether the sequence converges or diverges. If it converges, give the limit: 72, 18. 9/2, 9/8, ...
kakasveta [241]
Answer: The sequence converges. The limit it converges to is 0.

-------------------------------------------------------------------------------------------

The sequence is a geometric sequence with a = 72 and r = 1/4. Because 0 < r < 1, this means that the sequence gets smaller and smaller. The terms get closer to 0. They don't actually get there but the limiting value is 0.

Two angles form a linear pair. the measure of one angle is 26∘26∘ greater than the measure of the other angle. find the measure
Mashcka [7]
A linear pair is a pair of angles that form a line. And since they form a line, when added, they equal 180.

x = one angle....y = the other one
x + y = 180
x = y + 26
time to sub
y + 26 + y = 180
2y + 26 = 180
2y = 180 - 26
2y = 154
y = 154/2
y = 77 <=== this is one angle

x = y + 26
x = 77 + 26
x = 103 <=== and the other one
