Y<2 is the answer that I got
Answer:
w = 9r - g/ t
Step-by-step explanation:
subtract g
divide t
Answer:
y > -x -3
Step-by-step explanation:
The graph is shaded <em>above</em> the <em>dashed</em> line, indicating y-values in the solution are greater than those on the line, so your inequality will start with ...
y >
The y-intercept of the line is (0, -3), so the "b" value in ...
y > mx +b
will be -3.
The line has a rise of -3 for a run of 3 (between the marked points), so the slope is ...
m = rise/run = -3/3 = -1
Then the inequality you want is ...
y > -x -3
Answer:
<h2>The lifeboat has coordinates (5,10).</h2>
Step-by-step explanation:
The equation
represents the light beam from Ship A, which has coordinates
.
The equation
represents the light beam from Ship B, which has coordinates
.
This problem models a system of linear equations, because we need to find the coordinates of the lifeboat, which is a common points for both ships. So, basically, we just need to find the solution for the system formed by both equations.

We multiply the first equation by -1, and then sum


Now, we use this value to find the other one

Therefore, the lifeboat has coordinates (5,10).
The image attached shows the solution graphically.
Answer:
x= 57/2 or 28.5
Step-by-step explanation:
2x + 123 = 180
2x = 180 - 123
2x = 57
x = 57/2 (fraction form) or 28.5 (decimal form)
