In the function f(x) = (x^2 -6x + ___) + 20, what number belongs in the blank to complete the square?
Answer:
blank = -11
Step-by-step explanation:
The given function is :
[tex]f(x) = (x^2 -6x+x)+20[/tex]
We need to find the number x such that it forms the complete square.
If x = -11, then it will becomes,
[tex]f(x) = (x^2 -6x+(-11))+20\\\\f(x)=x^2-6x+9[/tex]
We can write it as follows :
[tex]f(x)=x^2-2(1)(3x)+(3)^2[/tex] ..(1)
We know that,
[tex](a-b)^2=a^2-2ab+b^2[/tex] ...(2)
Comparing (1) and (2).
[tex]f(x)=(x-3)^2[/tex]
So, if we put the blank equals -11, then it will become the perfect square.
Tiana uses 1 3/5 oz of detergent for each full load of laundry. How many full loads of laundry can she do with 100 oz of detergent? Show your work.
Answer:
63 Full loads of laundry
Step-by-step explanation:
We have been told in the question that 1 3/5 oz or 8/5 oz of detergent is used for a full load of laundry.
So,
1 full load of laundry requires 8/5 oz of detergent
Then,
x full loads of laundry require 100 oz of detergent
100 = 8/5x
x = 100 * 5/8
x = 63 Full loads of laundry (to the nearest whole number)

how many solutions does 3x+4=3x-2 have?
Answer: 2
Step-by-step explanation:
Answer:
No solutions.
Step-by-step explanation:
3x+4−3x=3x−2−3x
4=−2
4−4=−2−4
0=−6
0 does not equal -6, so there are no solutions.

The dimensions of a standard tennis court are 36 ft. × 78 ft. with a net that is 3 ft. high in the center. The court is modified for players aged 10 and under such that the dimensions are 27 ft. × 60 ft., and the same net is used. Use similarity to determine if the modified court is similar to the standard court.
Answer:
Modified court is not similar to the standard court
Step-by-step explanation:
Given that :
Dimension of standard tennis court:
36ft by 78ft
Net height = 3 ft
Dimension of Modified Court :
27ft by 60ft
Net height = 3ft
To examine similarity :
We obtain the dilation factor for width and length :
(Standard court length / modified court length)
= 36 ft / 27 ft
= 4 / 3
Width :
Standard court width / modified court width)
= 78 ft / 60 ft
= 13 / 10
Since the dilation factor for the width and length are different, then we can conclude that the standard and modified court are not similar

Nolynn mixes 4 3/4 cups of water with 2/3 cup of lemonade concentrate. How many cups of
water did Nolynn mix per cup of lemonade concentrate?
Answer:
7 1/8 cups of water
Step-by-step explanation:
You can multiply 2/3 by 3 to get 2 and do the same to 4 3/4 to get 14 1/4. You then divide 2 by 2 and 14 1/4 by 2 to get 7 1/8 per cup of lemonade concentrate.

Answer:
y = - 2
Step-by-step explanation:
Locate x = 2 on the x- axis, go vertically down to meet the graph at (2, - 2 )
Then when x = 2, y = - 2
Answer:
According to the above graphical figure it is found that,
When the input value of x is 2, output value of y is -2.
Location on the graph → (2,-2).

Answer:
ead the excerpt from "The Most Dangerous Game,” by Richard Connell.
His foot touched the protruding bough that was the trigger. Even as he touched it, the general sensed his danger and leaped back with the agility of an ape. But he was not quite quick enough; the dead tree, delicately adjusted to rest on the cut living one, crashed down and struck the general a glancing blow on the shoulder as it fell; but for his alertness, he must have been smashed beneath it. He staggered, but he did not fall; nor did he drop his revolver. He stood there, rubbing his injured shoulder, and Rainsford, with fear again gripping his heart, heard the general's mocking laugh ring through the jungle.

Answer:
y = 3x -5
Explanation:
Since it's parallel, it will have the same slope: 3.
So you'll have y = 3x + a, and we need to find a.
Plug in the values for the point we are given:
7 = 3(4) + a
7 = 12 + a
a = -5
So there you have it: y = 3x - 5Answer:
y=3x-5
Step-by-step explanation:
y=3x+6
since the line is parallel, the slope will be the same (but y int is still unsolved)
so plug in x,y from (4,7) in y=mx+b or y-y1=m(x-x1)
i used y=mx+b
7=3(4)+b
7=12+b
b=(-5)
so the final answer is y=3x-5
