Answer:
x = 9(a+g)
Step-by-step explanation:
x/9 - g = a
Add g to each side
x/9 - g+g = a+g
x/9 = a+g
Multiply each side by 9
x/9 * 9 = 9(a+g)
x = 9(a+g)
The single line marks indicate the two lines have the same length. Thus, the unknown length is 3 cm. 15 mm = 1.5 cm, 25 mm = 2.5 cm. The rest is trivial.
<u>it is the first one</u>, because y CAN be 1-3x, so the line is solid. then, it is a simple matter of placing it correctly based on the y-intercept, which is one. the shading goes under the line because it is <u>less than </u>or equal to
