Y = -3x + 7

The 7 is where the graph touches the y-axis (so when x = 0); in this case, it crosses (0 , 7). The value next to 'x', or the coefficient, is the slope of the line. The slope is the change in y for a certain n change in x. It's -3 in this graph.

40 degree, 3x, and 4x solve for x

Answer:

The value of x would be 20

Step-by-step explanation:

To solve this triangle, we need to first note that all triangles have 180 degrees. So we can add these all together and set equal to 180.

40 + 3x + 4x = 180

40 + 7x = 180

7x = 140

x = 20
