Answer:
We can not see all the graphs, so i will just do a graph of the system of inequalities, and you can select the option that matches it.
We have the system:
y ≥ 2x + 1
(to represent this, we need to have a solid line y = 2x + 1, and shade all the region above this)
y ≤ 2x - 2
(to represent this, we need to have a solid line y = 2x - 2, and shade all the region below this)
The graph of this system is shown below:
Answer:
An equation of a line is written in the form y=mx+b. ”m” is the slope and “b” is the y-intercept.
Slope: 4
y-intercept: -7 or (0,-7)
:)
The answer would be the second picture. Also, if you have any questions like these you can go on desmos and put in the equation to see the answer. Hope this helps!
Probably the coordinate plane, since there are 2 number lines (which is the x and y axis). Therefore, it it perpendicular and forms a right angle. Hope this helps!
Answer:
4) d = 60; e = 90
5) f = 30
6) h = 120
Step-by-step explanation:
4)
d + d + d = 180
3d = 180
d = 60
e + e + e + e = 360
4e = 360
e = 90
5)
70 + (180 - 100) + f = 180
70 + 80 + f = 180
f = 30
6)
45 + 75 + (180 - h) = 180
300 - h = 180
-h = -120
h = 120
