Answer:
Step-by-step explanation:
9x - 77 = 7x - 43
2x - 77 = -43
2x = 34
x = 17
9(17) - 77 = 153 - 77 = 76
7(17) - 43 = 119 - 43 = 76
z + 76 = 180
z= 104
Answer:
-6/7
Step-by-step explanation:
The slope of DE is ...
(change in y)/(change in x) = (y2 -y1)/(x2 -x1) = (-3-4)/(1-7) = -7/-6 = 7/6
The slope of the line perpendicular to DE is the negative reciprocal of this:
perpendicular slope = -1/slope = -1/(7/6) = -6/7

Answer:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). Watch this video to learn more about it and see some examples. Created by Sal Khan.

Is it a multiple choice question? I mean, 10/80?..
Answer:
£3,543.54
Step-by-step explanation:
Amount after 2 years = Principal + interest
Get the interest
Interest = PRT/100
Interest = 3003 * 9 * 2/100
Interest = 3003 * 18/100
Interest = 30.03 * 18
Interest = 540.54
Amount after 2 years = 3003 + 540.54
Amount after 2 years = £3,543.54
