Parallel lines have the same slope so for the new line we m=-2 and the point (2,2) we will substitute this info into our line to solce for b the y intercept.
Y=-2x+b
(2)=-2(2)+b
2=-4+b
2+4=-4+4+b
6=b
Now we put it all together using the slope m=-2 and the y intercept of 6
Y=-2x+6
Answer:
length=12cm breadth=7cm
Step-by-step explanation:
l=5+b
P=2(l+b)
38=2(5+b+b)
19=5+2b
14=2b
b=7
l=5+7=12
Answer:
t^2+4
Step-by-step explanation:
The perimeter of the table can be given by the equation 2l+2w, and we know the length is 2t-3, meaning 2(2t-3)+2w=2t^2+4t+2, as we know 2t^2+4t+2 is the perimeter. Simplifying we get:
4t-6+2w=2t^2+4t+2
4t+2w=2t^2+4t+8
2w=2t^2+8
w=t^2+4
This means that the table's width is t^2+4
Answer: 
<u>Step-by-step explanation:</u>
Monica has some cookies: x
She gave seven to her sister: x - 7
Then she divided the remainder into 2: 
She still had five cookies left: 
To solve, multiply both sides by 2, then add 7 to both sides.
