Answer:
y = 10/2x + 0
Step-by-step explanation:
Slope Int Form: y = m(slope)x + b(y-intercept)
The number before the x is the slope. To find the slope, count how far up or down and how far to the right or left. The b in the equation is the y-int so find the y-int of the graph.
Answer:
C
Step-by-step explanation:
x = 7 cos (2pi/3) y = 7 sin (2pi/3)
x = -7/2 y = 7 sqrt(3) /2
Answer:
Step-by-step explanation:
45 = (b(4b - 2))/2
90 = 4b2 - 2b
4b2 - 2b - 90 = 0
(2b + 9)(2b - 10) = 0
2b + 9 = 0
2b = -9
b = -9/2
If we were looking for zeroes, this would be an answer, but since we're looking for measurement, we don't use negative numbers.
90 = 4b2 - 2b
4b2 - 2b - 90 = 0
(2b + 9)(2b - 10) = 0
2b + 9 = 0
2b = -9
b = -9/2
For the second problem the answer D, -9, -11
