Graph the equations to solve the system y=-x-2 y=2x+4

Mathematics
1 answer:
Nady [450]3 years ago
6 0

Answer:

The solution is (-2, 0).

It is very easy to graph these two equations. You have the y-intercept for the first equation which is -2, and the slope -1/1. The y-intercept for the second equation is 4, and the slope is 2/1.

When you graph these two equations, you will see that they intersect at the point (-2,0); this is the answer.

Find x and round to nearest tenth
Lesechka [4]

Answer:

x=13.5

Step-by-step explanation:

Using the formula:

Sin theta=opposite/hypotenuse

Where theta=57 degrees

opposite =10.8

hypotenuse =x

Sin57=10.8/x

Xsin57=10.8

x=10.8/sin57

x=10.8/0.8

x=13.5

Which graph shows the solution to the system of linear inequalities?
V125BC [204]
<h2><u>Answer:</u></h2>

Which ordered pairs are in the solution set of the system of linear inequalities?

y > Negative one-halfx

y < One-halfx + 1

On a coordinate plane, 2 straight lines are shown. The first solid line has a negative slope and goes through (0, 0) and (4, negative 2). Everything above the line is shaded. The second dashed line has a positive slope and goes through (negative 2, 0) and (2, 2). Everything below the line is shaded.

(5, –2), (3, 1), (–4, 2)

(5, –2), (3, –1), (4, –3)

<h2><u>(5, –2), (3, 1), (4, 2)</u></h2>

(5, –2), (–3, 1), (4, 2)

The sum of the measures of angle LMN and angle NMP is 180 degrees
Vaselesa [24]

Answer:

angle LMN is 153 degrees.

Step-by-step explanation:

180 = 15g + 18 +3g; combine like terms

180 = 18g + 18; subtract 18 on both sides

162 = 18g; divide 18 on both sides

g = 9

plug in: 15(9) + 18 = 153
