Answer:
A.
Step-by-step explanation:
Rotations preserve shape <u>and</u> size, but a dilation with a factor of 3, no matter where in the sequence of transformations it is, results in a shape 3 times larger. So rotation followed by the dilation will end up being a rectangle similar to the original but 3 times its size.
Which of the following relationships represents a function?
Answer: B
The best way to solve this one is with a proportion:
(15 steps) / (5 minutes) = (75 steps) / ('x' minutes)
Cross-multiply the proportion: 15 x = 5 x 75
Divide each side by 15 : x = 5 x 5 = <em>25 minutes</em>.
You are correct, and Paul walks very slowly.
Answer:
slope is -5
Step-by-step explanation:
This equation is in slope-intercept form:
where m is the slope and b is the y-intercept.
In the given equation, the slope is -5 and the y-intercept is 1.
Answer:
158
Step-by-step explanation:
Simplify the following:
2×5×3 + 2×5×8 + 2×3×8
5×3 = 15:
2×15 + 2×5×8 + 2×3×8
5×8 = 40:
2×15 + 2×40 + 2×3×8
3×8 = 24:
2×15 + 2×40 + 2×24
2×15 = 30:
30 + 2×40 + 2×24
2×40 = 80:
30 + 80 + 2×24
2×24 = 48:
30 + 80 + 48
