Answer:

A. -6.5°C/km

Step-by-step explanation:

It's easier to find slope if we can locate two points.

Looking at the graph, it looks like it passes through the points (4, -10) and (7,-30).

To find the slope, we divide the difference of the y-coordinates by the difference of the x-coordinates. Here, the difference in the y-coordinates is:

-10 - (-30) = -10 + 30 = 20

The difference in the x-coordinates is:

4 - 7 = -3

So, the slope is:

20/(-3) = -20/3 ≈ -6.67

This is the closest to the first answer choice, -6.5°C/km, so that is the answer.

I need help on this question, not to good with graph. Anybody help pleaseee!!
LenKa [72]

y = -3x - 2

Since a < 0 we have a decreasing line, so it can be only the first or the last

And if we solve the equation for y = 0 we have

0 = -3x - 2

3x = -2

x = -2/3

So, the last one is the right

1.7 In the following diagram, angle 7 equals 61°.
gladu [14]
1.7) < 7 and < 8 form a linear pair....which means, when added, they equal 180 degrees. So if < 7 = 61, then < 8 = (180 - 61) = 119 <=

1.8) angles that are supplementary will add up to 180. So if one of the angles is 38, then the other one is (180 - 38) = 142 <==

1.9) < 3 = < 5 (vertical angles are congruent)
1.10) < 2 = < 8 (vertical angles are congruent)
1.11) < 7 = < 1 (vertical angles)
1.12) < 6 = < 4 (vertical angles)

Solve for the missing side in the following right triangle: hypotenuse = 17, leg = 8, leg = ?.
krek1111 [17]
Hyp^2 = leg1^2 + leg2^2
hyp^2  -leg1^2 = leg2^2
17^2 - 8^2 = leg2^2
leg2^2 = 289 -64
leg2^2 = 225
leg2 = 15

How do you solve this? 18 " n=21
dalvyx [7]
18 ^{n} =21

log(18) ^{n}=log(21)

n*log(18)=log(21)

n= \frac{log(21)}{log(18)}

n=1.053

What slope would a line have to be perpendicular to a line with a slope of 1/4 ?
denpristay [2]

Answer:

A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line. The negative reciprocal of the original line is –2, and is thus the slope of its perpendicular line.
