Answer:
Adding the 2 known angles: 60° + 100° = 160° We subtract this from 180°. 180° – 160° = 20°. Our missing angle is 20°. To find a missing angle in a triangle we subtract the two known angles from 180°.
Step-by-step explanation:
<span>4x+2y=-6
2y = -4x - 6
y = - 2x - 3
slope = -2
</span><span>y-intercept when x = 0
so y = -3
answer
slope = -2
</span><span>y-intercept (0,-3)</span>
I would personally take the number three and trow it out the window but that's not what we are talking about
Twice a number (2x) decreased by 7 (- 7).
2x - 7
Two times a specfic number (x) subtracted by 7.
