As we know the formula to calculate the slope is m = y2 - y1 divided by x2 - x1.
Where m is the slope. y2 is the second y co ordinate. y1 is the first y co ordinate. x2 is the second x co ordinate. x1 is the first x co ordinate.
So to calculate we can write it out as -7 = v - (-5) / 5 - 7, which further becomes -14 = v + 5 and v comes out to be -19.
Answer:
A= 65 C= 65 and D= 115
Step-by-step explanation:
given a parallelogram .
interior angles sum is 360 degree.
sum of adjacent angles is 180degree.
opposite angles are congruent (B=D).
A + B + C + D = 360
(A + D) + C + 115 = 360 since A and D are adjacent angles .
180 + 115 + C = 360
295 + C = 360
C = 360 - 295
C = 65
D = 115
A = 65
a+b+c+d=360
65 + 65 + 115 + 115 = 360
130 + 230 = 360
360 = 360
A. The relation is a function if one x-value goes out to one <em />y-value. We can check the graph for that. Does any x-value come out to more than one y-value? No, so, therefore, yes, the relation is a function.
B. The domain is all the x-values shown in the relation. Therefore, it is Domain:{-4, -3, -2, 0, 2, 3}
C. Like the domain question, it is the y-values shown. Therefore, the range is Range: {2, 0, -1, 2, -3, 3}
D. The value of y is at x=2 is the y-value of the point that it shows in the relation when x = 2. We find the point where x=2 (the fifth one from the left), and the y-value there is -3
