In order to find the y-intercept you have to plug in 0 for x in the equation, so:
f(0) = -1.4(0) - 15
When you solve, you would get y-intercept = -15
In order to find the x-intercept you have to set the equation equal to 0, so:
0 = -1.4x - 15
Solve for x and you would get -10.714...
f(15) = -1.4(15) - 15
f(15) = -36
-1.4x - 15 = 12.44
Add 15 to both sides
-1.4x = 27.44
Divide both sides by -1.4
x = -19.6
Answer:
576 feet
Step-by-step explanation:
I'm going directly off the graph but it looks like the y-coordinate of the vertex is 576, which would make 576 feet the maximum height. Hope that helps :)
Answer:
c:10
Step-by-step explanation:
7^2+ =
= 25
x =5 (but that is only 1/2 of the length you are looking for
5*2 = 10
Answer:
Factor each coefficient into primes. Write all variables with exponents in expanded form.
List all factors—matching common factors in a column. ...
Bring down the common factors that all expressions share.
Multiply the factors as in (Figure).
Step-by-step explanation:
Well, -11/10 is also -1.1. So, it goes right next to -1 on a number line.
