A scale factor of 3 was used, because Figure B's measurements are 3 times Figure A's measurements.
Hope that helped!
Answer:
-5cd
Step-by-step explanation:
<u>Simplifying:</u>
- -3cd - d(2c - 4) - 4d = ⇒ parenthesis
- -3cd - 2cd + 4d - 4d = ⇒ simplify like terms
- -5cd ⇒ answer
The first choice is correct one.
Answer:
- y = 6/7 x - 6 Your answer could be
- y = 0.857 x - 6
Step-by-step explanation:
Remark
- Start by solving for y. Divide both sides by 7
- y = 6/7 x - 14/7
- y = 6/7 x - 2
- Parallel lines all have the same slope. What you know so far is that the slope of the new line must be 6/7
- y = 6/7x + b
- Now you use the given point to solve for b
Givens
Solution
- 0 = 6/7 * 7 + b Reduce the fraction
- 0 = 6 + b Subtract 6 from both sides
- -6 = 6 -6 + b
- b = - 6
Answer
- y = 6/7 x - 6 Your answer could be
- y = 0.857 x - 6
Answer:
2m/s/s
Step-by-step explanation:
It was 0 m/s/s before, and now it is 10 / 5 = 2 m/s/s
Answer:
71 degrees.
Step-by-step explanation:
m < CED = 180 - 152 = 28 degrees ( adjacent angles).
m <BAC = 28 degrees( alternate angles).
m < ACD = 28 + 43 = 71 degrees (external angle theorem).
