“y” is a part of a straight angle, so
131 + y = 180
y = 180 - 131
y = 49 [degrees].

The coordinate grid shows points A through K. What point is a solution to the system of inequalities? y &lt; −2x + 10 y &lt; 1 o
VashaNatasha [74]

The graph that represents the system of inequalities will be y ≤ −2x + 3; y ≤ x + 3

<h3>How to depict the graph?</h3>

The equation of the line will be:

y = mx + b

In this case, we can observe that both lines have the same y intercept and that the lines are solid.

Hence, graph that represents the system of inequalities will be y ≤ −2x + 3; y ≤ x + 3. The graph is attached.

When the coordinate grid shows points A through, the point that is a solution to the system of inequalities is negative 6 point G at negative 3, negative 10 point H at negative 4.

Finally, the graph that represents the following system of inequalities: y ≤ −3x + 1 y ≤ 1 over 2x + 3 is the graph of two intersecting lines where both lines are solid.

One line of x passes through points negative 2, 2 and 0, 3 and is shaded above the line. The other line g of x passes through points 0, 1 and 1, negative 2 and is shaded above the line.

Does - |-4| = | -(-4)?
Marta_Voda [28]
The first is an absolute value sign.  But there is a - outside the first one so the -4 does become positive but then becomes negative again so you have -4 

The second value is basically saying the same thing as -1x-4 which become a negative times a negative which is positive. You end up with 4.  

So no it does not equal each other. 

I do see an extra absolute value symbol though on the right side of the equal sign.  But it looks like either way it would be -4 = 4 and that's not true.  So either way it should be false.

If y=kx, where k is a constant, and y=24 when x=6, what is the value of y when x=5?A. 6B. 15C. 20D. 23
Marizza181 [45]

First, we will find the value of k

We can do this by sybstituting y=24, x=6 in;

y=kx and then solve for k

24= k(6)

divide both-side of the equation by 6

24/6 = k

4 = k

k=4

Then when x = 5, we will substitute x=5 and k=4 in; y=kx and then solve for y

y= (4)(5)

y = 20
