Answer:
x=17 or x=19
Step-by-step explanation:
(x−18)^2=1
First, simplify both sides of the equation.
x*2−36x+324=1
Then subtract 1 from both sides.
x^2−36x+324−1=1−1
x^2−36x+323=0
Factor left side of equation.
(x−17)(x−19)=0
Then set factors equal to 0.
x−17=0 or x−19=0
x=17 or x=19
Answer:
Its either x=17 or x=19

Find the slope of the line without graphing using the 2 points below.
(-2 , 1) & (-5 , 5)
m=____
Answer:
-4/3
Step-by-step explanation:
m = slope = (difference in y)/(difference in x)
m = (y2 - y1)/(x2 - x1)
m = (5 - 1)/(-5 - (-2))
m = 4/(-5 + 2)
m = -4/3

Question 9 options:

As your question is missing some information, so after some research I was able to find the potential question you wanted to ask which is:
Point A is located at negative 4 over 6 and point B is located at negative 1 over 6. What is the distance between points A and B?
So, I am going to answer you based on the complete question I was able to find, which anyways would clear your concept.
Answer:
The distance between A and B will be: [tex]\frac{3}{6}[/tex]
Step-by-step explanation:
From the question statement, it is clear that
Point A is located at negative 4 over 6 i.e. -4/6, and
point B is located at negative 1 over 6 i.e. -1/6.
As we know that we can determine the distance between two negative numbers on a given line by finding the distance by taking the absolute value of the difference between those numbers.
so,
Distance between A and B will be:
[tex]\left|-\frac{4}{6}-\left(-\frac{1}{6}\right)\right|=\left|-\frac{4}{6}+\frac{1}{6}\right|[/tex]
[tex]=\left|\frac{-4+1}{6}\right|[/tex]
[tex]=\left|-\frac{3}{6}\right|[/tex]
[tex]=\frac{3}{6}[/tex]
Hence, the distance between A and B will be: [tex]\frac{3}{6}[/tex]
point A is located at -2, 5
point B is located at 5,5
the distance is 7 units

Find the number if 5/6 of it is 55.
Answer:
The unknown number is 66.
Step-by-step explanation:
We know that we need to find the number that is 55 when calculated as 5/6 or the whole number. First, we must divide 55 by 5.
55 ÷ 5 = 11
This means that 1/6 of the unknown number is 11.
Now, let's multiply 11 by 6.
11 x 6 = 66
Therefore, the unknown number is 66.
Hope this helps! :)

pile of sand has weight of 90kg the sand is put into a small bag, medium bag and a large bag in the ratio 2:3:7
work out the weight of sand in each bag
Answer:
Sand in small bag = 2x = 2(7.5) = 15 kgSand in medium bag = 3x = 3(7.5) = 22.5 kgSand in a large bag = 7x = 7(7.5) = 52.5 kgStep-by-step explanation:
Total weight = 90 kg
As 90 kg has been distributed in 3 bags in the ratio 2:3:7
Let the small bag contains = 2x
Let the medium bag contains = 3x
Let the big bag contains = 7x
so the equation becomes
2x+3x+7x = 90
12x = 90
x = 90/12
x = 7.5
Thus,
Sand in small bag = 2x = 2(7.5) = 15 kgSand in medium bag = 3x = 3(7.5) = 22.5 kgSand in a large bag = 7x = 7(7.5) = 52.5 kgSOLUTION CHECK
15+22.5+52.5=90 kg
A pool is in the shape of a rectangular prism. On Monday, water was pumped out of the pool at a constant rate, starting at 12:00 p.m. At 12:15 pm, the water in the pool was 45 inches deep. At 12:25 p.m., the water in the pool was 41 inches deep. Write an equation that represents y, the depth of the water (in inches), after x minutes.
Answer:
y = 51-0.4x
Step-by-step explanation:
From the question, we can see that the amount of water left in the pool was 45 inches deep within 12:15-12:00 = 15 minutes
However, within 10 minutes there was a loss of 45-41 = 4 inches
So what this means is that per minute, the amount of loss expected is 4 inches/10 minutes = 0.4 inches per minute
what we are saying is that a loss of 4 inches depth of water is needed per minute
So we want to write an equation, representing the depth after x minutes
So what we have here is that the total inches at present will be;
45 + 0.4(15) = 45 + 6 = 51 inches
The pool was 51 inches deep initially before the pumping out began
That will be;
y = 51-0.4x
where is the depth and x is the number of minutes
Answer:
24 inches

Mary has $65,000 to invest in two accounts. The first account is a private savings offering 6% annual interest and the second account is a government savings account offering 4% annual interest. How much money should Mary invest in each account to make $3520 in total annual interest.
Answer:
first account with 6% interest ( x ) = $46000
second account with 4% interest ( y ) = $19000
Step-by-step explanation:
Principal = $65000
first interest rate = 6%
second interest rate = 4%
assuming ; X = money invested in first account , Y = money invested in second account
hence :
( 65000 - y ) * 6% + ( 65000 - x ) * 4% = 3520
3900 - 0.06 y + 2600 - 0.04 x = 3520
0.04 x + 0.06 y = 3900 + 2600 - 3520
0.04 x + 0.06 y = 2980 ----- ( 1)
x + y = 65000 ------- ( 2 )
solve equation 1 and 2 simultaneously by elimination method
0.04 x + 0.06 y = 2980 ------ ( 3 )
0.06 x + 0.06 y = 3900 ------- ( 4 )
subtract equation 3 form equation 4
0.02 x = 920 , hence x = $46000
therefore y = $65000 - $46000 = $19000

Shaq invested $900 into a savings account that pays annual simple interest. At the end of 9 years, he earned $461.70 in interest. What is the interest rate on the savings account? Round to the nearest tenth of a percent.
Answer:
Interest = $900 * x * 9 years with "x" = interest rate
If interest = 461.70 then
461.70 = 900 * 9 * x
x = 461.70 / 8,100
x = interest rate = .057 = 5.7%
Double Check
Interest rate of 5.7 per cent equals
.057 * 900 = $51.30 per year
Nine Years = 9 * 51.30 equals 461.70
So, it's correct!!!

The Anderson family is preparing for a family reunion. They think they will need 22 juice boxes for every 6 children who attend. How many juice boxes will they need if they are expecting 15 children?
Answer:
52
Step-by-step explanation:
26 divided 4 multiplied by 8 equals 52
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
1 children = 22/6 juice boxes
15 children = 55 juice boxes
The number of juice boxes that are needed for 15 children is
55 juice boxes.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
They think they will need 22 juice boxes for every 6 children who attend.
This can be written as,
6 children = 22 juice boxes
Divide 6 on both sides.
1 children = 22/6 juice boxes
Multiply 15 on both sides.
15 children = 15 x 22/6 juice boxes
15 children = 5 x 11 juice boxes
15 children = 55 juice boxes
Thus,
The number of juice boxes that is needed for 15 children is
55 juice boxes.
