If you are describing transformations with respect to the graph of f(x) = x:
f(x) = x has no transformation
g(x) = (x+2) - 3 is the graph of f(x) translated 2 units left and 3 units down
2(h(x) = x-1) is the graph of f(x) vertically expanded by a factor of 2 and then translated 1 unit right
d(x) = 1/2x + 2 is the graph of f(x) vertically compressed by a factor of 1/2 and then translated 2 units up
Answer:
for #14, x=10
Step-by-step explanation:
in the graph, 6x = 5x +10 so if x was 10 it would be 60 = 60 so x = 10
Answer:
Variance = 25
Step-by-step explanation:
<em>Standard deviation is the under root of variance.</em>
<em>Variance is the square of standard deviation.</em>
<u>Data:</u>
Mean = 70
Variance = ?
Standard deviation = √variance = 5
Variance = 5²
Variance = 25.
Therefore, the variance is 25.
Answer:
Step-by-step explanation:
Well the first fact is that you can solve H and J with 1 equation. Two remote (unconnected to) one of the exterior angles when summed, equals the unconnected exterior angle.
H + j are not connected to the exterior angle at I.
Put more directly
2x + 3x = 150 Combine
5x = 150 Divide by 5
x = 150/5
x = 30
So H = 2 * 30 = 60
and J = 3*30 = 90
All triangles have interior angles that add up to 180
We have already accounted for 150.
JIH + 150 = 180 Subtract 150
jIH = 180 - 150 = 30
Summary
x = 30
JIH = 30
H = 60
J = 90
