Write f(x) = 2x2 – 44x 185 in vertex form. to write f(x) = 2x2 – 44x 185, factor out from the first two terms. next, form a perfect square trinomial keeping the value of the function equivalent: f(x) = 2(x2 – 22x 121) 185 – 242 the function written in vertex form is f(x) = (x – )2 .
The quadratic function given when converted to vertex form will be: [tex]f(x) = 2(x-11)^2 -57[/tex]
What is vertex form of a quadratic equation?If a quadratic equation is written in the form
[tex]y=a(x-h)^2 + k[/tex]
then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)
We first take out coefficient of x squared, and then inside the bracket, we try to make perfect square like situation.
For this case, the given quadratic function is:
[tex]f(x) =2x^2 -44x + 185\\[/tex]
Converting this to the vertex form, we get:
[tex]f(x) =2x^2 -44x + 185\\\\f(x) = 2(x^2 -22x) + 185\\f(x) = 2(x^2 -2 \times 11 \times x + 11^2 - 11^2) + 185\\f(x) = 2((x-11)^2 -121) + 185\\f(x) = 2(x-11)^2 -242 + 185\\f(x) = 2(x-11)^2 -57[/tex]
Thus, the quadratic function given when converted to vertex form will be: [tex]f(x) = 2(x-11)^2 -57[/tex]

Given f(x) = 3x-1 and g(x)=2x-3, for which value of x does g(x)=f(2)? Ox=3/2 Ox-2 Ox=5/2 Ox=4
====================================================
Work Shown:
First find f(2)
f(x) = 3x-1
f(2) = 3(2)-1 ... replace every x with 2
f(2) = 6-1
f(2) = 5
--------------
The equation g(x) = f(2) is the same as g(x) = 5 since f(2) = 5
g(x) = 2x-3
5 = 2x-3 .... replace g(x) with 5
2x-3 = 5
2x = 5+3 ... add 3 to both sides
2x = 8
x = 8/2 .... divide both sides by 2
x = 4
The value of x that satisfies the equation g(x) = f(2) is x = 4.
What is a function?A relation is a function if it has only One y-value for each x-value.
We are given two functions f(x) and g(x), and we need to find the value of x that satisfies g(x) = f(2).
We know that f(x) = 3x - 1, so f(2) = 3(2) - 1 = 5.
Therefore, we need to find the value of x that makes g(x) equal to 5.
Setting g(x) equal to 5, we get:
2x - 3 = 5
Add 3 to both sides.
2x = 8
Divide both sides by 2:
x = 4
Therefore, the value of x that satisfies the equation g(x) = f(2) is x = 4.

Mrs. Rodger got a weekly raise of ₫145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of ₫ 145.
So after completing the 1st week she will get ₫ (x+145).
Similarly after completing the 2nd week she will get ₫ (x + 145) + ₫ 145.

If PT=u and QS=u–28, what is the value of u?
Answer:
u = 56
Step-by-step explanation:
the midsegment QS is half the length of the third side PT , that is
QS = [tex]\frac{1}{2}[/tex] PT ( substitute values )
u - 28 = [tex]\frac{1}{2}[/tex] u ( multiply through by 2 to clear the fraction )
2u - 56 = u ( subtract u from both sides )
u - 56 = 0 ( add 56 to both sides )
u = 56
Ellie has been training for the Cedar Ridge Off-Road Race. The first week she trained, she ran 3 days and took the same two routes each day: 2. 5 miles on a path in the woods in the morning and a longer route at the park in the afternoon. By the end of the week, Ellie had run a total of 24 miles. Which equation can you use to find how many miles, x, Ellie ran each afternoon?
The distance that Ellie ran each afternoon is 5.5 miles for a whole week.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the distance that Ellie ran each afternoon, since she ran 24 miles, hence:
3(2.5 + x) = 24
7.5 + 3x = 24
x = 5.5 miles
The distance that Ellie ran each afternoon is 5.5 miles for a whole week.

if 3x + 28 = 46 what is the value of 2x + 6
Answer:
18
Step-by-step explanation:
3x + 28 = 46
Subtract 28 from each side
3x + 28 = 46
3x+28-28 = 46-28
3x=18
Divide each side by 3
3x/3 = 18/3
x = 6
Find 2x+6
2(6)+6
12+6

Hey there!
3x + 28 = 46
SUBTRACT 28 to BOTH SIDES
3x + 28 - 28 = 46 - 28
CANCEL out d 28 - 28 because it give you 0
KEEPs 46 - 28 because it help solve for the x-value.
NEW EQUATION: 3x = 46 - 28
SIMPLIFY IT!
3x = 18
DIVIDE 3 to BOTH SIDES
3x/3 = 18/3
CANCEL out: 3/3 because it give you 1
KEEP: 18/3 because it give you the x-value.
NEW EQUATION: x = 18/3
SIMPLIFY IT!
x = 6
Now that we have your x-value we can substitute it into the equation of: 2x + 6
SIMPLIFYING:
2x + 6
= 2(6) + 6
= 12 + 6
= 18
Thus, your answer is: 18
