Answer:
The equation you are given is a quadratic. The standard form of a quadratic is y = a(x-h)2 + k where (h,k) is the vertex of the graph, which is a parabola. Vertically moving the graph 4 units upward means that you are moving k +4 units.
y = a(x-h)2 + k standard form
y = 5x2 - 4 original equation
y = 5(x-0)2 - 4 re-written in standard form
h = 0 k = -4
Four (4) units up is k + 4--->-4 + 4 = 0.
Therefore, f(x) = 5x2 + 0--->f(x) = 5x2.

Step-by-step explanation:
Let's make the number we're finding to be
. So, it says that it will be divided by 4 and then added by 12 if we want this in algebraic expression it will be
. It's also telling us that that expression is the same thing as our number divided by 3 and subtracted by 5. If we want an expression out of it it well be
. Since they are the same, we have the equation below.

All we have to do now is to find
.

<h3>Answer:</h3>
Our number must be
. I think
Answer:
Step-by-step explanation:
place x = 19
f(19) = 3 / 19 + 2 - Sqrt 21 - 3
= 3/21 - 4
= - 81/21
= - 27/7
