Answer:
∠ ELM = 149°
Step-by-step explanation:
∠ KLM = ∠ KLE + ∠ ELM , substitute values
17x - 1 = 20 + 15x - 1
17x - 1 = 15x + 19 ( subtract 15x from both sides )
2x - 1 = 19 ( add 1 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
Then
∠ ELM = 15x - 1 = 15(10) - 1 = 150 - 1 = 149°
Plot the points on a graph and join them to form a closed figure. two sides that are parallel shows it is a trapezoid
Step-by-step explanation:
Just graph it and see if the descriptions fit the graph
(see attached)
A. We can see from the graph that the possible x-values are -∞ ≤ x ≤ +∞ . Hence limiting to domain to x≤ -2 this is obviously not true.
B. We can see from the graph that the vertex is y = 6 and that the entirety of the graph is under this point, hence range y<6 is true
C. We can see that the vertex is located at x=-2. Every part of the graph to the left of this point has a positive slope, hence the function is increasing for negative infinity to this point x=-2 is true
D) We can see that for the interval -4<x<∞, the graph actually increases between -4<x<-2, and then decreases after that. Hence this statement is not true.
E. it is obvious that the y intercept is y=2 which is positive. Hence this is true.
A) 40
B) 30
C) 20
a) 10 and 4
b) 10 and 6
c) 10 and 8
Answers:
C) 20 —-> a) 10 and 4
B) 30 —-> b) 10 and 6
A) 40 —-> c) 10 and 8
Explanation:
20: 10 x 2 = 20 ; 4 x 5 = 20
30: 10 x 3 = 30 ; 6 x 5 = 30
40: 10 x 4 = 40 ; 8 x 5 = 40
