Question:
Correctly complete this sequence: 131, 517, ?, 123
Answer:
The completed sequence: 131, 517, 192, 123
Step-by-step explanation:
Given sequence is 131, 517, ?, 123
Step 1: Now, write the given numbers without any commas as below,
131517?123
Step 2: Then, split it into two digit numbers as 13, 15, 17, _ _, 23
Step 3: Fill the sequence with the missing two digit odd numbers. So, we can write as below
13, 15, 17, 19, 21, 23
Step 4: Again, rewrite and form the sequence without any commas.
131517192123
Step 5: Place the class after every three digits.
131, 517, 192, 123
Step 6: At last, found that the missing number is 192.
This is a simple addition sequence. The next number in the sequence would be 903, resulting from the addition of 386 to the previous term 517. So, the completed sequence is 131, 517, 903, 123.
Explanation:The sequence in question appears to be a simple addition sequence between consecutive terms. If you subtract the first number from the second number, you get 386 (517-131 = 386). Assuming this addition pattern continues, you can find the next number in the sequence by adding 386 to 517. So, the next number in the sequence would be 903 (517 + 386).
This means the completed sequence should read: 131, 517, 903, 123. Always remember to check the difference between your terms when working with sequences like this one.

Write a linear function f with the values f(2)=4 and f(−7)=9. A function is f(x)=
Answer:
f(x) = -5/9 x + 5 1/9
Step-by-step explanation:
f(2)=4 and f(−7)=9 means the line pass through (2,4) and (- 7,9)
f(x) = mx + b
m = (y-y') / (x-x') = (9 - 4) / (- 7 - 2) = - 5/9
for (2,4) : b = f(x) - mx = y - mx = 4 - (- 5/9) x 2 = 4 + 10/9 = 46/9 = 5 1/9
f(x) = -5/9 x + 5 1/9
check for (-7, 9) f(-7) = (-5/9) * (-7) + 5 1/9 = 35/9 + 46/9 = 81/9 = 9
Final answer:
The linear function that satisfies the given points f(2)=4 and f(-7)=9 is f(x) = (-5/9)x + (46/9).
Explanation:
To write a linear function f(x) that satisfies f(2)=4 and f(-7)=9, one must determine the slope and y-intercept of the line. A linear function has the form y = mx + b, where m is the slope and b is the y-intercept.
First, let's find the slope using the two points (2, 4) and (-7, 9):
Slope (m) = (y2 - y1) / (x2 - x1) = (9 - 4) / (-7 - 2) = 5 / -9.
Now we have the slope which is -5/9. We can use one of the points and the slope to find the y-intercept (b). Let's use the point (2, 4):
4 = (-5/9)(2) + b
b = 4 + (10/9) = 46/9
Therefore, the linear equation of the function is:
f(x) = (-5/9)x + (46/9).
Shawn hike 12 miles and 4 hours at the same rate what is the total number of miles he could hike in 9 hours
Answer:
27 miles
Step-by-step explanation:
Find the rate or speed that Shawn hikes at. Find this reduced to lowest terms.
speed = distance / time
speed = 12 miles / 4h
speed = 3miles / h
Every hour, Shawn hikes 3 miles.
Multiply speed by time to find distance.
3mph X 9h = 27 miles
Therefore Shawn could hikes 27 miles in 9 hours.

Answer:
(x, y ) → (x + 6, y + 12 )
Step-by-step explanation:
We require to determine the horizontal and vertical shift to go from one of the points on the line to the corresponding point on the image
Consider point V with x- coordinate - 8 and y- coordinate - 2
The corresponding point is V'
with x- coordinate - 2 and y- coordinate 10
Thus V → V' is 6 units right in the horizontal direction and 12 units up in the vertical direction.
These are the same shifts for W → W'
Thus the translation rule is
(x, y ) → (x + 6, y + 12 )
The equation which correctly represents this situation is
A) x2 = 306
B) 2x2 = 306
C) x2 + x = 306
D) 2x2 + x = 306
Answer:
C) x2 + x = 306
Step-by-step explanation:
x2 + x = 306
x2 + x - 306 = 0
x2 + 18x - 17x + 18 * (-17) = 0
x ( x + 18) - 17 (x +18) =0
(x + 18) (x - 17 ) = 0
x = -18 or 17
What is the area of this triangle in square inches?
area of triangle = 1/2bh
area = 1/2(120)(252) = 15120 in²
answer: C
Answer:
C) 15,120 square inches
Step-by-step explanation:
To solve this problem we first need to convert both legs of the triangle to inches. 10 ft * 12 is 120 and 7 yards is roughly 21 ft and that times 12 is 252. All we have to do now is to plug these values into the formula for area of a triangle: 1/2(b x h) = 1/2(252 * 120) = 1/2(30240) = 15,120 square inches.

Step-by-step explanation:
42. 7x + 13 ≥ 55
⇒ x ≥ 6
So, it matches graph a.
43. 12x - 8 > 4(3x + 2)
⇒ 12x - 8 > 12x + 8
Hence, d. not possible.
44. [tex]\frac{x}{- 4} - 3 < - 1[/tex]
⇒ [tex]\frac{x}{- 4} < 2[/tex]
⇒ x > - 8
Hence, graph e matches.
45. - 4(- 2x + 3) ≤ 5 + 8x
⇒ 8x - 12 ≤ 5 + 8x
⇒ - 12 ≤ 5
This is true for all values of x, hence that matches graph c.
46. - 4(x + 3) > 8(x + 3)
⇒ - 4x - 12 > 8x + 24
⇒ 12x < - 36
⇒ x < - 3
Hence, graph b matches the situation. (Answer)

Separate the number 41 and the two parts so that the first number is eight more than twice the second number what are the two numbers
The two numbers are 30 and 11
Solution:
Given that we have to separate the number 41 into two parts
Let the second number be "x"
Given that first number is eight more than twice the second number
first number = eight more than twice the second number
first number = 8 + twice the "x"
first number = 8 + 2x
So we can say first number added with second number ends up in 41
first number + second number = 41
8 + 2x + x = 41
8 + 3x = 41
3x = 41 - 8
3x = 33
x = 11
first number = 8 + 2x = 8 + 2(11) = 8 + 22 = 30
Thus the two numbers are 30 and 11

.
Answer:
A. The Number of Lost games = 154 Games
B. Number of games won is greater than the number of games lost.
Step-by-step explanation:
A. how many games did they lose in both years?
Total Number of games = 104 tournaments x 3 Games in each tournament
Total Number of games = 312 Games
The No. of Lost games= Total Games in 2 years - Games won in 1st year - Games won in 2nd year
The No. of Lost games = 312 - 55 - 103
The No. of Lost games = 154 Games
B. Is the number of games won greater than the number of games lost?
Total Number of Games won = 158 Games
Total Number of Games lost = 154 Games
Hence, Total Number of Games won is greater than the Total Number of Games lost.

QUESTION 5 of 10: Your laptop died and you need a new one for work NOW! The one you need will cost $500. You do not have the cash in
your checking account, so you decide to borrow the money from your savings account. You have $9,000 in your savings account gaining
3% interest per year. If you don't replace the $500 in the savings account, how long will it take before the balance again reaches $9,000?
a) 1 year
b) 2 years
c) 5 years
Answer:
B
Step-by-step explanation:
9000-500 = 8500
8500 × (3/100) =255
8500 + 255 = 8755
8755 × (3/100) = 262.65
8755 + 262.65 = 9017.65
hence, the answer is B
*please correct me if im wrong ^^
Answer:
b) 2 years
Step-by-step explanation:
If you have $9000 in the saving account, and you take $500, you are left with:
$9000 - $500 = $8500
in one year you will have 3% more of the 8500 which is:
8500/100*3 = $255
so in one year the number on your savings account is:
8500 + 255 = $8755
and by the next year you will have 3% more of the 8755 which is:
8755/100*3 = $262.65
so in two years the number on your savings account is:
8755 + 262.65 = $9017.65
which is a little bit more than the $9000.
so it will take 2 years until the calance again reaches $9000

Step-by-step explanation:
x^2 + 10x − 25 = 0
we can solve this by finding out the value of x
lets assume the equation is a\times x^{2}+b\times x+c=0
x=-b\pm \sqrt{(b^{2}-4ac)}\div 2a
x=-10\pm\sqrt{100+4*25}\div2
x=-5\pm5\sqrt2
then we get both real value of x

h(x)= 1/8x^3-x^2
What is the average rate of change of h over the interval −2≤x≤2?
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [a, b ] = [ - 2, 2 ], thus
f(b) = f(2) = [tex]\frac{1}{8}[/tex] × 2³ - 2² = 1 - 4 = - 3
f(a) = [tex]\frac{1}{8}[/tex] × (- 2)³ - (- 2)² = - 1 - 4 = - 5
average rate of change = [tex]\frac{-3-(-5)}{2-(-2)}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]
The average rate of change of h over the interval −2≤x≤2 is 1/2.
Here,
The function is [tex]h(x)= \frac{1}{8} x^3-x^2[/tex] and the interval −2≤x≤2.
We have to find, the average rate of change of h over the interval −2≤x≤2.
What is Average rate?
The Average rate of change of function f( x ) in the close interval [a, b ]
is, [tex]\frac{f(a)-f (b)}{b-a}[/tex]
Now,
The function is [tex]h(x)= \frac{1}{8} x^3-x^2[/tex] and the interval −2≤x≤2.
Hence, [tex]h(-2) = \frac{1}{8} *(-2)^{3} -( -2)^{2} = -5[/tex]
And, [tex]h(2) = \frac{1}{8} *(2)^{3} -( 2)^{2} = -3[/tex]
So, Average rate of change of function h(x) = [tex]\frac{-3-(-5)}{2-(-2)} = \frac{2}{4} = \frac{1}{2}[/tex]
The average rate of change of h over the interval −2≤x≤2 is 1/2.

If 10 minutes is how long it took Lisa to walk 1/4 of the way home, how long does it take to walk 2/3 of the way home?
Answer:
[tex]26\frac{2}{3}[/tex] minutes (or 26 minutes 40 seconds)
Step-by-step explanation:
This problem can be very easily solved with ratios and proportions.
We can create two ratios and equate them. Then we cross multiply and find the unknown.
Let the time it takes to walk 2/3rd of the way be "t".
We will keep minutes on top (numerator) and the fractional way on the bottom (denominator) when creating our ratios.
Simply put, 10 mins = 1/4th of the way, so "t" mins means 2/3rd of the way. Thus we can write:
[tex]\frac{10}{\frac{1}{4}}=\frac{t}{\frac{2}{3}}\\\frac{1}{4}t=10*\frac{2}{3}\\\frac{1}{4}t=\frac{20}{3}\\t=\frac{\frac{20}{3}}{\frac{1}{4}}\\t=\frac{20}{3}*\frac{4}{1}\\t=\frac{80}{3}\\t=26\frac{2}{3}[/tex]
sO, IT IS GOING to take [tex]26\frac{2}{3}[/tex] minutes to go 2/3rdof the way.
Or, 26 minutes and 40 seconds
Final answer:
To find out how long it takes to walk 2/3 of the way home, set up a proportion using the information given. so 26.7 minutes take to walk.
Explanation:
To find out how long it takes to walk 2/3 of the way home, we can set up a proportion using the information given. If 10 minutes is how long it took Lisa to walk 1/4 of the way, we can say that:
10 minutes = 1/4 of the way
To find out how long it takes to walk 2/3 of the way, we can set up another proportion:
x minutes = 2/3 of the way
We can cross multiply the proportions to solve for x:
10 * (2/3) = x * (1/4)
20/3 = x/4
To solve for x, we can multiply both sides of the equation by 4:
80/3 = x
So, it takes approximately 26.7 minutes to walk 2/3 of the way home.

one half the cost of a dress decreased by $12 is the same as 2/5 the cost of a dress. What is the cost of the dress?
Answer:
$120
Step-by-step explanation:
Let the cost of the dress be "c"
ONE HALF the cost DECREASED by 12, can be written as:
[tex]\frac{1}{2}c-12[/tex]
2/5th the cost of dress, can be written as:
[tex]\frac{2}{5}c[/tex]
Now, we equate both parts and solve for c to get cost of dress. Shown below:
[tex]\frac{1}{2}c-12=\frac{2}{5}c\\\frac{1}{2}c-\frac{2}{5}c=12\\\frac{5-4}{10}c=12\\\frac{1}{10}c=12\\c=\frac{12}{\frac{1}{10}}\\c=12*10\\c=120[/tex]
Thus,
The ccost of the dress is $120
