Answer:
1 C
2 G
Step-by-step explanation:
First you need to solve for "x": 6x+3=8x-21, 3=2x-21, 24=2x, x=12.
Then plug in number 12 to your equation: 6(12)+3=75;
Just to make sure that I solved correctly for x, plug in 12 into the second equation: 8(12)-21=75.
Yahoo, the x is 12 and angle measure is 75°.

Answer:
7.4 seconds
Step-by-step explanation:
878 = 16 t^2 divide both sides of the equation by 16
54.875 = t^2 take positive sq rt

Answer:
y = 1x + 2
Step-by-step explanation:
To fill in slope intercept form(y = mx + b) identify the initial value(b) and slope(m).
The initial value is the y coordinate when the x coordinate is 0. It is also known as the point where the line crosses the y axis. This point on the graph is (0, 2). So, the initial value is 2.
Slope is identified by finding a point on the graph that the line passes through and creating a right triangle to a point that is even with both point. Then, divide the y coordinate of that point by its x coordinate. One coordinate you could use is point (-2, 2). 2 divided by -2 is -1. But, since the line has a positive association, the slope is going to be a positive number. So, the slope is 1.
Now fill in the the slope intercept form.
y = mx + b ---> y = 1x + 2
