Answer:
y = 5x - 3
Step-by-step explanation:
As we move from the point (-2, -13) to the point (1, 2), we see the x-value (the 'run') increasing by 3 and the y-value (the 'rise') increasing by 15. Therefore the slope of the line passing thru these two points is m = rise / run = 15/3, or m = 5.
Using the slope-intercept formyula y = mx + b, we find the y-intercept as follows, using 1 for x, 2 for y and 5 for m:
2 = 5(1) + b, or
b = -3
Then the desired equation is
y = 5x - 3
1st angle = 3x
2nd angle = x
3rd angle = 65 +x
3x + x +65+x = 180
5x+65 = 180
5x=115
x = 115/5 = 23
2nd angle = 23 degrees
1st angle = 23 x 3 = 69 degrees
3rd angle = 65 +23 = 88 degrees
Answer:
Step-by-step explanation:
1/16 + 1/2 = 1/16 + 8/16 = 9/16
Answer:
79-22=8h
Step-by-step explanation:
She can earn the rest by babysitting for only 8 hours,
so take 22 from 79, divide the total by 8 and that is how much she gets per hour (8h)
Negative 3x over the power by four
