Answer:
y=2x+1
Step-by-step explanation:
First you have to find the slope:
5-1/2 so 4/2 or 2
Then you write it in point-slope: (I used the point (0,1))
y-1=2x
Simplify than:
y=2x+1
Answer:
6m-mn, or 5m-n.
7y+42+5y+30, or 12y+72.
Not sure exactly what you're asking for the third and fourth, but these are the first two simplified.
Answer:
about 3141.59 cm^3
Step-by-step explanation:
V of cylinder = (pi)(r^2)(h)
radius = 10 cm
height = 10 cm
V = pi x 10^2 x 10
V = 3141.59 cm cubed
The number of years past when Alan was twice Vanessa's age is 14 years.
Current ages :
- Alan = 30 years
- Vanessa = 22 years
<u>We can set up an equation where, x = number of years when Alan was 2 times Vanessa's age thus</u> :
30 - x = 2(22 - x)
30 - x = 44 - 2x
Collect like terms
-x + 2x = 44 - 30
x = 14
Therefore, 14 years ago, Alan's age was twice Vanessa's age.
