<h3>x intercept is -3 and y intercept is 9</h3>
<em><u>Solution:</u></em>
<em><u>Given equation of line is:</u></em>
y = 3x + 9
<u>Find the x intercept:</u>
Substitute y = 0 in given
0 = 3x + 9
3x = -9
Divide both sides by 3
x = -3
Thus x intercept is -3
<u>Find the y intercept:</u>
Substitute x = 0 in given
y = 3(0) + 9
y = 0 + 9
y = 9
Thus the y intercept is 9
By solving a system of equations, we will see that m measures 12 units.

How to get the measure of m?</h3>
Notice that we have 3 right triangles.
Then we can write the equations:
cos(a) = 6/m
For the small triangle on the left, where m is the hypotenuse.
cos(a) = m/(6 + 18)
For the larger triangle (the one composed of the two triangles).
Where in both equations, angle "a" is the one in the top left.
Then we have the system of equations:
cos(a) = 6/m
cos(a) = m/(6 + 18)
Then we can write:
6/m = m/(6 + 18)
If we simplify the expression, we get:
6*(6 + 18) = m^2
6*(24) = m^2
144 = m^2
√144 = m = 12
Then we conclude that m measures 12 units.

What do you mean? What’s the question?
Answer:
37.7
Step-by-step explanation:
The orginal answer is 37.699
But you want to round the tenth
So 9 to the 6 you want to rasie the score
6 turns into a 7 and the numbers behind it (9 and the other 9) turn into a zero
37.7 or 37.700
