Answer:
105
Step-by-step explanation:
One way to get this is by multiplying 15 by seven because the key says that one cm equals 7 km
Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}
{(2,4), (8,-3), (-5,-1), (4,6), (6,7), (9,0)}
The domain is the input and the range is the output
domain is { 2,8,-5,4,6,9} and the range is {4,-3,-1,6,7,0}
We put the numbers in order from smallest to largest
y − 1 = -2 (x − 3)
Point slope form is:
y − y₁ = m (x − x₁)
where m is the slope and (x₁, y₁) is a point on the line.
Given that m = -2 and (x₁, y₁) = (3, 1):
First problem. If you want a parallel to a given line, you keep the slope.
Then we use the point-slope form of a line
and we plug in there everything we need.
The second is quite similar. This time we want the perpendicular. It means that the product of the slopes has to be -1.
At this point we have everything, let's replace and write down the line in a better looking form
The product of 1/2 and the sum of x and y. Or 1/2 times the quantity of x+y
A sum is the answer to an addition problem and the product is the answer to a multiplication problem, sorry I don't really know how to explain it
