(5y - 1) + (-2y + 4) = 5y - 1 - 2y + 4
= 5y - 2y - 1 + 4
= 3y + 3 [OPTION B]
The best answer would be B or 785, hopefully this helped you
I take it you meant θ angle, anyway.
we know the tan(θ) = -4/7... alrite, we also know that 270° < θ < 360°, which is another to say that θ is in the IV quadrant, where the adjacent side or "x" value is positive whilst the opposite side or "y" value is negative.
Answer:
x = 20
Step-by-step explanation:
the sum of the interior angles of a triangle is 180°
add expressions for each angle then combine 'like terms':
6x - 5 + 2x - 3 + x + 8 = 180
9x - 8 + 8 = 180
9x = 180
x = 180/9
x = 20
Answer:
y = 7x
Step-by-step explanation:
1: slope (m)- as the x-variable goes up by 1, the y-variable goes up by 7. So, the ∆y/∆x = 7. Therefore,<em> the slope is 7</em>.
2: y-intercept (b)- When x = 0, <em>y also has to be 0</em>, since all of the x-variables multiplied by 7 gives the related y-variable, without any adding.
3: plug in- y = 7x + 0 --> y = 7x
