Y=5x+2 is the line for neither parallel nor perpendicular
1x=-1
that means whererever you see x, you replace it with -1
x is a placeholder for an unknown number
so repolace it
-1+5=4
5-1=4
true
Answer:
20 meters
Step-by-step explanation:
The shadow of the building will look like a right triangle. In this problem, the hypotenuse of the triangle is 25 meters, and one of the sides is 15 meters. What we are trying to find is the length of the other side.
We can do this by using pythagoreans theorem.

So, the last side (or the height of the building) is 20 meters.
Answer: $110
Step-by-step explanation:
Given: At Simba Travel Agency, the price of a climbing trip to Mount Kilimanjaro includes an initial fee plus a constant fee per meter.
F(d)models the fee (in dollars) for climbing d meters.

To find the initial amount, substitute d=0 int the above function, we get

Hence, the initial fee= $110.
Y belongs to ( 1 to 6) if x is zero
