3 1/2
2 1/4+ 1 1/4 = 3 2/4
or 3 1/2
4x = (130 - 2x) so x = 65/3
(3y + 40) + (130 -2x) = 180 because the angles are supplementary
plug in x
3y + 40 + 130 - 2(65/3) = 180
so 3y = 95/3
therefore y = 95/6
The answers would be letter b
Answer:
Step-by-step explanation:
The zeros are the values of x for which y=0.
The zero of this graph is x=1.
