Answer:
y = 6.5
Step-by-step explanation:
Using a ratio
10 13
----- = -----------
10+5 13+y
10 13
----- = -----------
15 13+y
Using cross products
10(13+y) = 13*15
10(13+y) = 195
130+10y = 195
Subtract 130 from each side
10y = 65
Divide by 10
y = 65/10
y = 6.5
No, is not a function because for the same value of X it has two different values of y, that’s not the definition of function.
Answer:
B) 2n + 1
Step-by-step explanation:
Each term increases by 2 units so the common difference is 2. Then plug in 1 into the equations that have a slope of 2 and see if you get 3 out. You do for 2n + 1.
Answer:
Step-by-step explanation:
Givens
P is (2,8)
Q is (-6,-6)
Equation
Midpoint = (x1 + x2)/2,(y1 + y2)/2
Solution
x1 = - 6
x2 = 2
y1 = -6
y2 = 8
M = (-6 + 2)/2, (-6+8)/2
M = -4/2, 2/2
M = -2 , 1
Just to make sure that you know that the answer is reasonable, I've put the midpoint (-2,1) on a graph with the two endpoints. You could print the points out and check it with a ruler.
