Answer:
Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.
Step-by-step explanation:
to find the distance between two point A(-4, -2) and B(-7, -7) we use the following distance formula

x1=-4, x2=-7
y1=-2, y2=-7
so,

Answer:y = -2x
Step-by-step explanation:
slope-intercept form is as follows
y = mx + b
You are given that the slope is -2 and since the line passes through the origin, there is no y-intercept
So you just plug in the slope
y = -2x + b
And since there is no y-intercept, you can take that out.
y = -2x
Set up;
(15^2)(CB) = (7.5^2)/(ST)
(15^2)/(5) = (7.5^2)/(ST)
Cross-multiply to find ST.
Answer:

Step-by-step explanation:
1. Blue region. The boundary blue line passes through the points (0,-7) and (3,8), then its equation is

This line is solid, so the sign for the inequality should be with the notion "or equal to".
From the diagram you can see that the origin belongs to the blue region, then its coordinates satisfy the inequality. Thus,

2. Green region. The boundary green line passes through the points (6,-1) and (0,3), then its equation is

This line is solid, so the sign for the inequality also should be with the notion "or equal to".
From the diagram you can see that the origin doesn't belong to the blue region, then its coordinates satisfy the inequality. Thus,

3. The system of linear inequalities that represents these graphs is
