Answer:
80°
Step-by-step explanation:
exterior angle = sum of two remote interior angles
27 + 53 = 80
Answer:
add it up to see if it's 180
Answer:
25
Step-by-step explanation:
okay, so we plug our numbers into the equation:
2a+3b = 2x8+3x3
2x8 = 16
3x3=9
16+9 = 25
Answer:
a) the same line
Step-by-step explanation:
The first equation is the "slope-intercept form" of the equation of a line with slope -3 and y-intercept +1. The second equation is the "point-slope form" of the equation of <em>the same line</em>. The "point" in this form is (x, y) = (2, -5), which is a point that satisfies the first equation:
y = -3x +1
-5 = -3(2) +1 . . . . true
The two equations represent the same line.
