F(t)
= t2 + 4t − 14
y + 14 + 4 = (
t2 + 4t +4)
y + 18 = ( t +
2)^2
so the vertex
of the parabola is ( -2 , -18)
<span>the axis of
symmetry is y = -18</span>
Answer:
In geometry, you can use deductive rules to prove that a given statement or conjecture is true or false using deductive reasoning.
Step-by-step explanation:
speed=d/t=200X2/5=80km/hr
d=sXt=13X80/4=260km
865/110=173/22hr=173X60/22=173X30/11=467min
Answer:
Step-by-step explanation:
f(x) = -1 is actually the same as y = -1. Find y = -1 on the y axis and then draw a horizontal line through this point. The resulting graph is that called for here.
Answer:
The answer is 3x+2
Step-by-step explanation:
2(3x-1)-3x+4
I did distributive property on 2(3x-1) how I did that was I multiplied 2 times 3x which is 6x (2 times 3x=6x). Then I multiplied 2 times -1 which equals -2 (2 times -1=-2).
new expression:
6x-2-3x+4
I combined all the numbers with the variables (6x and -3x) and by subtracting both of them you get 3x (6x-3x=3x). After that you combine -2 and 4 which equals 2 (-2+4=2).
This is now the final expression (your answer):
3x+2
