Answer:
angle 5 = angle 7 = 127°
Step-by-step explanation:
here , in the given figure ;
angle 2 + angle 5 = 180°
( pair of co-interior angles )
so, 53° + angle 5 = 180°
=》angle 5 = 180° - 53° = 127°
hence angle 5 = 127°
and angle 5 = angle 7 ( vertical opposite angles )
so, angle 5 = angle 7 = 127°
Answer:
y=5x+3
Step-by-step explanation:
You have the points (1,8) (2,13) (3,18) (4,23)
first you want to find the slope. The equation to find a slope is y2-y1 / x2-x1
your points (1,8) and (2,13) are really all you need
1 would be your x1 and your 2 would be your x2.
8 would be your y1 and 2 your y2
so you want to plug those into your equation y2-y1/x2-x1
13-8 /2-1 you get 5/1
Simplify your answer is 5 for your slope
Now finding the y intercept or "b" I normally just find the pattern of the sequence so in this case when you add one to the top your adding five to the bottom like
x 1 2 3 4
y 8 13 18 23
so to get to your y intercept which is (0,y)
subtract 1 from the top to get zero and subtract 5 from the bottom to get 3 so your y intercept is 3.
Hope this helps.

Answer:
Exact: $574 (3 sf)
Ordinary: $582 (3 sf)
Step-by-step explanation:
Exact:
253/365 × 7700 × 10.75/100
= $573.7554795
= $574 (3 sf)
Ordinary:
253/360 × 7700 × 10.75/100
= $581.7243056
= $582 (3 sf)
