F(x)= x - 10
f(-7) = - 7 - 10
f(-7) = - 17
Answer:
VW = 3
Step-by-step explanation:
From the diagram, we know that UW = 11.
We also know that UV + VW = UW, because UW is the length of the whole segment.
Using substitution (knowing 2 of the line segments), we find that 8 + VW = 11.
If we subtract 8 from both sides using inverse operations, we find that VW = 3, which is the answer.
Hope this helps!
Answer:
20%
Step-by-step explanation:
To find what percentage is $10 out of $50, we divide 10 by 50:

Step-by-step explanation:
Answer: 113.0cm²
Step-by-step explanation:
The surface area if a square is calculated as:
= 4πr²
where, radius = 3cm
Surface area = 4πr²
= 4 × 3.14 × 3²
= 4 × 3.14 × 9
= 113.04
= 113.0cm²
Therefore, the surface area is 113.0cm²
