319 is the term
Step-by-step explanation:
Please give me brainliest :)
Y = 3x
y = 4x - 1
3x = 4x - 1
<u>-4x -4x </u>
-x = -1
x = 1
y = 3(-1)
y = -3
(x, y) = (1, -3)
cos = adjacent/hypotenuse
cos 31° = 20/x
Cross multiply.
0.8571673007x = 20
Divide both sides by cos 31°.
x = 23.3 (rounded to nearest tenth).
