Answer:
speed = 67/6 miles per hour
Step-by-step explanation:
To find the average speed, we divide the distance by the time
d/t = 134 miles/ 12 hours
speed = 134/12 miles per hour
We can simplify this fraction by dividing the top and bottom by 2
speed = 67/6 miles per hour
Answer:
Range : { -5,1,7}
Step-by-step explanation:
Take the values in the domain and substitute into the equation
x = -3
y = -2(-3) +1 = 6+1 =7
x = 0
y = -2(0) +1 = 0+1 =1
x = 3
y = -2(3) +1 = -6+1 =-5
The range is the y values
We put then in order from smallest to largest
Range : { -5,1,7}
Answer:
I think it is the second one I guess so.
Answer:
Step-by-step explanation:
If a point is dilated by a scale factor 'k' centered at the origin,
Coordinates of the image point becomes as,
(x, y) → (kx, ky)
By this rule,
Coordinates of the vertices of the image triangle, when preimage is scaled by a factor of 5 about the origin will be,
T(-1, -2) → T'(-5, -10)
U(2, -2) → U'(10, -10)
V(-1, 1) → V'(-5, 5)
