Answer:
45, 46, 47Step-by-step explanation:
n, n + 1, n + 2 - three consecutive integers
The equation:
138 - n = (n + 1) + (n + 2)
138 - n = n + 1 + n + 2 combile like terms
138 - n = 2n + 3 subtract 138 from both sides
-n = 2n - 135 subtract 2n from both sides
-3n = -135 divide both sides by (-3)
n = 45
n + 1 = 46
n + 2 = 47
The three consecutive integers in question are 45, 46, and 47. This was solved by setting up and solving a simple algebraic equation.
Explanation:Solution:Let the three consecutive integers be x, x+1, and x+2. According to the problem, the sum of the second and third integers is equal to 138 minus the first one. This can be written mathematically as:
x + (x + 1) + (x + 2) = 138
Solving this equation gives:
3x + 3 = 138
3x = 135
x = 45
Hence, the three consecutive integers are 45, 46, 47.

Jackie is selling smoothies at a school fair. She starts the day with $15 in her cash box to provide change to her customers. If each smoothie costs $3.75, which graph represents the balance of the cash box, y, after Jackie sells x smoothies?
the answer would be D
Answer with Step-by-step explanation:
Jackie is selling smoothies at a school fair. She starts the day with $15 in her cash box to provide change to her customers.
Each smoothie costs $3.75, then cost of x smoothies is: $3.75x
Then, y=3.75x+15
When x=0 y=15
when x=4 y=3.75×4+15
i.e. y=30
The only graph which satisfies y=0 at x=0 and y=30 at x=4 is D.
Hence, the correct graph is:
D.

A. Quadratic monomial
B. Not a polynomial
C. Cubic binomial
D. Fourth-degree trinomial
Answer:
D. Fourth-degree trinomial
Step-by-step explanation:
I think this would be the correct answer because the highest degree the polynomial is raised to would be 4 (hence the fourth degree). It would be a trinomial because of 9x^4, 3x, and 4

Which expression is equivalent to (-3y-x)-(5y-8x)
A.-8y-8x
B.-8y+7x
C.2y-7x
D.8y+8x
Multiply the negative sign into the second bracket and get rid of both brackets
-3y-x-5y+8x
Collect like terms
-8y+7x
Answer:
B: -8y + 7x
Step-by-step explanation:
Start with (-3y-x)-(5y-8x). This is a subtraction problem. Subtract 5y from -3y, obtaining -8y. Next, subtract -8x from -x; this is equivalent to -x - (-8x), or 7x.
Then the difference -x + 8x = 7x.
Combining the x and y results, we get B: -8y + 7x.
PLEASE HELP DETAILS ARE BELOW I WILL RATE BRAINIEST CHORD AND ARCS FIND THE MEASURE OF ARC CD DETAILS BELOW
Wouldn’t it be 36.7 because that’s the arch am I right?
Answer:
The measure of arc CD is 114.6°.
Step-by-step explanation:
Let the center of the circle be O and OP is perpendicular to CD at point point P.
The perpendicular line from the center of circle divide each chord in two equal parts. so, CP=DP.
[tex]CP=\frac{CD}{2}=\frac{36.7}{2}=18.35[/tex]
In a right angles triangle,
[tex]\sin\theta =\frac{opposite}{hypotenuse}[/tex]
In a right angles triangle OPC,
[tex]\sin\angle POC =\frac{18.35}{21.8}[/tex]
[tex]\angle POC =\sin^{-1} (\frac{18.35}{21.8})[/tex]
[tex]\angle POC \approx 57.3[/tex]
In triangle OPC and OPD,
[tex]OC=OD[/tex] (Radius)
[tex]OP=OP[/tex] (Reflexive property)
[tex]CP=DP[/tex] (Altitude on chord from center)
By SSS postulate
[tex]\triangle OPC\cong \triangle OPD[/tex]
[tex]\angle POC\cong \angle POD[/tex] (CPCTC)
[tex]\angle POC=\angle POD[/tex]
The measure of angle COD is
[tex]\angle COD=\angle POC+\angle POD[/tex]
[tex]\angle COD=2\angle POC[/tex]
[tex]\angle COD=2(57.3)[/tex]
[tex]\angle COD=114.6[/tex]
Therefore the measure of arc CD is 114.6°.

Mr Johnson, the store owner, ordered 48 boxes of jawbreakers. Each box contained 392 pieces of candy. How many lawbreakers did Mr. Johnson order?
Answer:
Mr. Johnson would have ordered 18816 jaw breakers.
Step-by-step explanation:
Multiply 392 by 48
Mr. Johnson ordered a total of 18816 jawbreakers by multiplying the number of boxes (48) by the number of pieces of candy per box (392).
The question involves calculating the total number of jawbreakers Mr. Johnson ordered. To do this, we need to multiply the number of boxes ordered by the number of pieces of candy per box.
Step-by-step calculation:
Identify the number of boxes ordered: 48 boxes.
Identify the number of candies per box: 392 pieces.
Multiply the number of boxes by the number of candies per box to find the total: 48 boxes × 392 pieces/box = 18816 jawbreakers.
Therefore, Mr. Johnson ordered a total of 18816 jawbreakers.

The total cost of a dress,including tax, was $121.37. If 6% tax was added to the sale price, what was the sale price before taxes?
Answer:
We have
sale price + 6% x sale price = $121.37;
Then
(106/100) x sale price = $121.37;
sale price = $121.37 x 100 / 106;
sale price = $12137 / 106;
sale price = $114.50;
Step-by-step explanation:
To find the sale price of a dress before a 6% tax added up to a total of $121.37, divide the total by 1.06. The original sale price was $114.50.
The student is asking how to calculate the sale price of a dress before tax when the total cost, including a 6% tax, was $121.37. To find the sale price before taxes, you need to divide the total cost by 1 plus the tax rate expressed as a decimal.
First, convert the percentage to a decimal, which gives us 0.06 for a 6% tax. Then, add 1 to the tax rate (1 + 0.06 = 1.06) and divide the total cost by this sum to get the original price:
Sale price = Total cost / (1 + Tax rate)
Sale price = $121.37 / 1.06
Sale price = $114.50 (rounded to the nearest penny)
Therefore, the original sale price of the dress was $114.50.

Jack made $200 for working 40 hours. Saida made $242 for 44 hours of work. Are the pay rates proportional?
Answer:
No.
Step-by-step explanation:
If they are proportional, they equal each other.
We can use a proportion.
200/40 = 242/44
Simplify.
5 = 5.5
So they are not proportional.
Which function results after applying the sequence of transformations to
f(x) = x^5?
• stretch vertically by 3
• translate up 1 unit
• translate left 2 units
Answer:
The resulting function after the sequence of transformations is [tex]f(x)=3(x+2)^5+1[/tex]
Step-by-step explanation:
Given a function f(x)
the function a*f(x) will be a vertical stretch of factor a, given a > 1 the function f(x) + b will be the translated function vertically up b unitsthe function f(x+c) will be horizontally translated function of the original by c units leftRemembering these points, we can apply the rules to [tex]x^5[/tex].
Strech vertically by 3 would be [tex]3x^5[/tex]translate up 1 unit would be [tex]3x^{5}+1[/tex]translate left 2 units would make it [tex]3(x+2)^5+1[/tex]Hence the new function would be [tex]3(x+2)^5+1[/tex]
Answer:
f(x) = 3(x+2)⁵+1

A bookshop has a sale.
A book normally costing $39.95 is priced at $23.97.
By what percentage has the price been reduced?
please show working out
Answer:
The price been reduced by a percentage of 40%
Step-by-step explanation:
we know that
$39.95 -----> represent the 100%
so
The difference of prices is equal to ($39.95-$23.97)=$15.98
Using proportion
Find the percentage of the difference
100/39.95=x/15.98
x=100*15.98/39.95
x=40%
Answer:
40% is the percentage decreased.
Hope it helped!

Find the slope intercept form of the equation for the line that goes through (3, 5) and is parallel to y=5x - 1.
Answer:
y=5x-10
Step-by-step explanation:
slope intercept form is y=mx+b
since we know it is parallel to y=5x-1, we know that it has the same slope of 5.
So, we plug it in:
y=mx+b
y=5
x=3
(taken from point (3,5))
m=5
(taken from parallel line)
5=(5)(3)+b
5=15+b
b=-10
The equation would be y=5x-10
