Answer:
Step-by-step explanation:
[tex]f(x)=2x^2-44x+185\\\\=2(x^2-2*11*x)+185\\\\=2(x^2-2*11*x+11^2)+185-2*121\\\\\boxed{f(x)=2(x-11)^2-57}\\\\vertex\ is\ (11,-57)[/tex]
Answer:
f(x) = 2(x - 11)² - 57
Step-by-step explanation:
Given
f(x) = 2x² - 44x + 185 ( factor out 2 from the first two terms )
f(x) = 2(x² - 22x) + 185
To complete the square
add/ subtract ( half the coefficient of the x- term )² to x² - 22x
f(x) = 2(x² + 2(- 11)x + 121 - 121 ) + 185
= 2(x - 11)² + 2(- 121) + 185
= 2(x - 11)² - 242 + 185
f(x) = 2(x - 11)² - 57 ← in vertex form
and engineers didn’t answer 68 questions correctly on a 170 question trigonometry test what percent of the questions did she answer correctly?
Answer:
60%
Step-by-step explanation:
You see how many answers she got got right and to do that you subtract 170-68 and get 102. That's how many she answered correctly. Then you need to find the percentage and to do that you divide 102 by 170 which gives you 0.6, which can be read as 60%. Hope that helps! :)

If Y is the midpoint of R and T. and RY = 3x - 2 and YT = 8x - 22. Find the
value of RT. *
Your answer
Answer:
11x-24
Step-by-step explanation:
All you have to do is add (3x-2)+(8x-22)=11x-24.
Answer:
RT = 20
Step-by-step explanation:
Since Y is the midpoint of RT , then
RY = YT , that is
3x - 2 = 8x - 22 ( subtract 8x from both sides )
- 5x - 2 = - 22 ( add 2 to both sides )
- 5x = - 20 ( divide both sides by - 5 )
x = 4
Then
RT = RY + YT = 3x - 2 + 8x - 22 = 11x - 24 , so
RT = 11(4) - 24 = 44 - 24 = 20

Solve each for X. Show your work
10-1/2x = 6 + 3x
Answer:
[tex]x = \frac{8}{7} [/tex]
Step-by-step explanation:
[tex]10 - \frac{1}{2} x = 6 + 3x[/tex]
[tex]20 - x = 12 + 6x[/tex]
[tex]20 - x - 6x = 12 + 6x - 6x[/tex]
[tex]20 - x - 6x = 12[/tex]
[tex] - x - 6x = 12 - 20[/tex]
[tex] - 7x = 12 - 20[/tex]
[tex] - 7x = - 8[/tex]
[tex]x = \frac{8}{7} [/tex]
if a + b + c is cast 20 and a + b is equal to 14 , then c is what by process
Answer:
6
Step-by-step explanation:
[tex]a + b + c = 20[/tex]
[tex]a + b = 14(i)[/tex]
Putting value (a + b) in the above equation
[tex]14 + c = 20[/tex]
[tex]c = 20 - 14[/tex]
[tex]c = 6[/tex]

-16 + the quotient of a
number and -4 is -3
Answer:
76
Step-by-step explanation:
let the number be x
Then 16 + x/-4 = -3, so
x/-4 = -16-3 = -19 (add -16 on both sides)
x = -4*-19 = 76 (multiply by -4 on both sides)
