Answer:
119 degrees
Step-by-step explanation:
17x + (-2 + 9x) = 180
17x - 2 + 9x = 180
26x = 182
x = 182/26 = 7
17x = 17(7) = 119 degrees
So the shop is offering 65% off, by taking 100% - 65%, we only have to pay for 45%. In fact, 45% = 45/100 = 0.45
So here's the equation y = 0.45x
That's the point-slope form of the equation of a line.
Answer:
11 and 2/3.
Step-by-step explanation:
6 and 3/12 = 72/12 + 3/12 = 75/12.
5 and 5/12 = 60/12 + 5/12 = 65/12.
75/12 + 65/12 = 140 / 12 = 70 / 6 = 35 / 3 = 11 and 2/3.
Hope this helps!
Use the slope form:
m= (y2-y1)/(x2-x1)
Plug in two sets of points from table 4. (0,9) (2,4)
m= (4-9)/(2-0)
m= -5/2 or -2.5
Do the same for the second table. I can't see it very well, so I am assuming that number under 1 is 5. (0,3) and (1,5)
m= (y2-y1)/(x2-x1)
m= (5-3)/(1-0)
m= 2/1 or 2
I hope this helps!
