We need the ordered pairs to choose an answer, but if you want to do it yourself you plug in the x and y values (x,y) and test to see if the equation is true, and equals -19.
The Statue of Liberty and its pedestal are 92.99 meters tall. The pedestal is 0.89 meter taller than the statue. Let s represent the height of the Statue of Liberty. So, s + 0.89 represents the height of the pedestal. Equation: s + (s + 0.89) = 92.99
s + (s + 0.89) = 92.99 2s + 0.89 = 92.99
– 0.89 = – 0.89 2s = 92.10
s = 46.05
The Statue of Liberty is 46.05 meters tall.
The vertex of the absolute value function f(x) = |x| is (0,0).
What about <span>f(x)=-|x+2|-2? This can be re-written as f(x) = -|x-(-2)| -2.
Three things happen here: first, the graph of f(x) = |x| must be inverted, so that it opens down instead of up; second, the resulting graph must be translated 2 units to the left; and third, the resulting graph must be translated 2 units down.

Answer:
2 hours=120 mins
120-(45+25)
120-(70)
50
Ron has enough time to finish his homework and walk the dog before his lesson. Ron should overestimate the total time needed. Since Ron has 50 minutes to spare he could add 25 to home work time and another 25 to walking his dog. he still ha time to do both.
A linear function has the form y=mx+b
if you insert the point (0,5) in this you receive:
5=m*0+b
5=b
(remember b is the distance to the x axis at x=0, so you can read it directly of)
To get m you insert (4,8) and the previous b:
8=m*4+5
3=4m
3/4=m
your line is: y=3/4x+5
(also this question is a duplicate of #3469085 by you :) )
