Answer:
1/10 in first row
1/20 in second row
1/5 in third row
Step-by-step explanation:
it is simple, take first row, and look what is required to get 1,
here 5*2 is 10, so to get 1 we need to divide with 10
in second row, 20*1 is 20, so we need to divide with 20
and in third row 10* ½ is 5, so we need to divide with 5
Answer:
y = 3x + 6
Step-by-step explanation:
The domain is you x values. You need to substitute the x values into both functions to see which one produces the plots on the graph.
<h3>y = 2x + 4</h3>
when x = -3, y = 2(-3) + 4 = -6 + 4 = -2
when x = -2, y = 2(-2) + 4 = = -4 + 4 = 0
when x = -1, y = 2(-1) + 4 = = -2 + 4 = 2
when x = -0, y = 2(0) + 4 = 0 + 4 = 4
<h3>y = 3x + 6</h3>
when x = -3, y = 3(-3) + 6 = -9 + 6 = -3
when x = -2, y = 3(-2) + 6 = = -6 + 6 = 0
when x = -1, y = 3(-1) + 6 = = -3 + 6 = 3
when x = -0, y = 3(0) + 6 = 0 + 6 = 6
The points on the graph are (-3, -3), (-2, 0), (-1, 3) and (0, 6)
This is same as the results from the function y = 3x + 6
Answer:
c
Step-by-step explanation:
right now 15 is the mode because there are 3 of them
if we made it so that there was another 8 there would also be 3 of them
this would mean that there are two modes

Answer:
∠A = 90
∠B = 30
∠C = 60
Step-by-step explanation:
Let ∠B = x
∠A = 3x
∠C = x + 30
Angle sum property of triangle: Sum of three angles of triangle is 180
x + 3x + x + 30 = 180 {Combine like terms}
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 130/5
x = 30
∠A = 3*30 = 90
∠C = 30 + 30 = 60
