Answer:
x^2-16x=13
x^2-16x+64=13+64
x^2-16x+64=77
(x-8)^2=77 or (x-8)^2-77=0
Adding 64 came from doing (b/2)^2 where b is the constant in ax^2+bx+c, I hope this helps.

How many 5-digit numbers are there in which three of the digits are 6, or two of
the digits are 9 ?
Answer:
The value is [tex]Z = 80[/tex]
Step-by-step explanation:
From the question we are told that
The total number of digit is n = 5
The total possible number of 6 is k = 3
The total possible number of 9 is a = 2
Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 3 of the digit are 6 is mathematically represented as
[tex]N = ^ nP_k[/tex]
Here P stands for permutation hence we are going to be making use of the permutation function in our calculators
[tex]N = ^ 5P_3[/tex]
=> [tex]N = 60[/tex]
Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 2 of the digit are 9 is mathematically represented as
[tex]M = ^ nP_a[/tex]
[tex]M = ^ 5P_2[/tex]
=> [tex]M = 20[/tex]
Generally the number of 5-digit numbers there are in which three of the digits are 6, or two of the digits are 9 is mathematically represented as
[tex]Z = M + N[/tex]
=> [tex]Z = 60 + 20[/tex]
=> [tex]Z = 80[/tex]

Answer:
There are 5 terms in the series.
Step-by-step explanation:
[tex]S=a\frac{1-r^{n} }{1-r}\\a=-3\\r=6\\-4665=-3\frac{1-6^{n} }{1-6}\\1555=\frac{1-6^{n} }{-5}\\\-7775=1-6^{n}\\6^{n}=7776\\[/tex]

Solve this system of equations, then determine what y equals.
x + 5y= 7
2x + 4y = -4
y=-18
y=3
y=8
y=-8
Answer: [tex]y = 3[/tex]
1. First, solve for unknown x.
[tex](x+5y=7)2[/tex]
2. Balance the equation.
[tex]2x+10y=14[/tex]
[tex]\mathrm {2x + 4y = -4}[/tex]
3. Now, we subtract.
[tex]6y = 18[/tex]
[tex]6[/tex] × [tex]3 = 18[/tex]
4. Finally, divide.
[tex]18/6=3[/tex]

6. The Awesome Bowl Factory makes two kinds of bowls. They produce a
basic bowl every 9 minutes and a gigantic bowl every 12 minutes. They
start at 8:00 A.M. At what time are the basic bowl and the gigantic bowl
first produced together?
Answer: 8.36 a.m
Step-by-step explanation:
To solve this, first we need to calculate the lowest common multiple of 9 and 12.
Multiples of 9 = 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108.
Multiples of 12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120.
Here, the lowest common multiple = 36
Therefore, we will add 8.00am plus 36 minutes. This will be:
= 8:00 a.m + 36 minutes
= 8.36 am
The time that the basic bowl and the gigantic bowl are first produced together is 8.36 am.
The regular price of a laptop computer is $914.00. This week, it is on sale for $886.00 of
What is the sale price of the computer?
Answer:
3.1%
Step-by-step explanation:
Subtract.
914 - 886 = 28
Divide by the original price.
28/914 = 0.0306345...
Multiply by 100%.
0.0306345... * 100% = 3.06345%
Round if needed.
3.06345% -> 3.1%
Best of Luck!

A home improvement store advertises 60 square feet of flooring for $287.00 including an $80.00 installation fee. How much does each square foot of flooring cost?
50 POINTS *GIVEING BRAINLIEST*
60 square feet= $287.00 + $80.00
= $367
1 square feet= $367 / 60
= $6.116666667
= $6.12 (to 2dp) ( answer)
Answer:
60 square feet for 287 = 287/60 = 4.78 per square foot
so ur equation would be : y = 4.78x + 80

Brandon enters bike races.
He bikes 8 /2 miles every 1/2 hour.
How fast did he go
Answer:
He goes 8 miles an hour
Step-by-step explanation:
8/2 is equal to 4. If Brandon bikes 4 miles in half an hour and keeps a constant speed he ends up biking 8 miles in an hour since two halves of an hour make one.

Find the slope of the line through the
given points: (5,-4) & (-1,-4).
Answer:
m=0
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
Since -4-(-4)=0, we know that the slope has to be zero since the numerator is zero.

What is the answers help me please part A B C
Giving extra points
Correct answer
Answer:
A, 38, 40
Step-by-step explanation:
a. A has to be the first graph because it starts at $ 25 and it rises as more work needs to get done
b.if you go from 50 up until you get to the line, then look left at the axis is about $38
c. C=25+s*0.25, substitute c=35 and find s
35=25+s*0.25 subtreact 25 from both sides
35-25= s*0.25
10=s*0.25 divide both sides by 0.25
10/0.25=s
40=s
