The function 2x + 3 is equivalent to g(x) + f(x) if the g(x) = (9x + 1) and f(x) = (-7x + 2)
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
h(x) = (3x - 4)
f(x) = (-7x + 2)
g(x) = (9x + 1)
Find h(x) + g(x):
= (3x - 4) + (9x + 1)
= 12x -3
Find g(x) + f(x):
= (9x + 1) + (-7x + 2)
= 2x + 3
Thus, the function 2x + 3 is equivalent to g(x) + f(x) if the g(x) = (9x + 1) and f(x) = (-7x + 2)

In which direction must the graph of f(x) = x be shifted to produce the graph of g(x) = x - 16?
Answer: Option C.
Step-by-step explanation:
The equation of the line in slope-intercept form is:
[tex]y=mx+b[/tex]
Where the slope is "m" and the intersection of the line with the y-axis is "b".
Given the function f(x) in the form [tex]f(x)=x[/tex], you can identify that:
[tex]m=1\\b=0[/tex]
This means that the line passes through the origin (0,0)
And from the function g(x) in the form [tex]g(x)=x-16[/tex], , you can identify that:
[tex]m=1\\b=-16[/tex]
This means that the line of the function g(x) and the line of the function f(x) have the same slope, but the line of g(x) passes through the point (0,-16)
Therefore, the graph of f(x) must be shifted 16 units down to produce the graph of g(x)

What’s the distance between (-3,-22) and (-13,-23)
Answer:
d = sqrt(101)
Step-by-step explanation:
To find the distance between two points, we use the formula
d =sqrt ((x2-x1)^2 + (y2-y1)^2) where (x1,y1) and (x2,x2) are the points
d = sqrt ((-13--3)^2 + (-23--22)^2)
d = sqrt ((-13+3)^2 + (-23+22)^2)
d = sqrt((-10)^2 + (-1)^2)
d = sqrt(100)+1)
d = sqrt(101)
What is the missing value in the equation shown □ x1/10=0.034
Answer:
0.34
Step-by-step explanation:
Do the inverse operation so;
0.034 / 1/10 = 0.34
Now go back and subsitute,
0.34 * 1/10 = 0.034
In the equation □ x 1/10 = 0.034, the missing value is 0.34 as obtained by isolating □ on one side, i.e., □ = 0.34.
Explanation:The equation presented in the question is □ x 1/10 = 0.034. The missing value is the number that should be multiplied by 1/10 to result in 0.034. To solve for this missing value, we can rearrange the equation using the basic algebraic method. We isolate the missing value (□) on one side by dividing both sides of the equation by 1/10. This results in □ = 0.034 / (1/10), which simplifies further to □ = 0.34. Therefore, the missing value in the equation □ x 1/10 = 0.034 is 0.34.

So changing value of "a" changes the amplitude of the sine graph.
A transformation T : (x, y) → (x + 3, y + 1). Find the preimage of the point (4, 3) under the given transformation. (7, 4) (1, 2) (4/3, 3) (-1, -2)
Answer:
(1, 2)
Step-by-step explanation:
Remember that the final shape and position of a figure after a transformation is called the image, and the original shape and position of the figure is the pre-image.
In our case, our figure is just a point. We know that after the transformation T : (x, y) → (x + 3, y + 1), our image has coordinates (4, 3).
The transformation rule T : (x, y) → (x + 3, y + 1) means that we add 3 to the x-coordinate and add 1 to the y-coordinate of our pre-image. Now to find the pre-image of our point, we just need to reverse those operations; in other words, we will subtract 3 from the x-coordinate and subtract 1 from the y-coordinate.
So, our rule to find the pre-image of the point (4, 3) is:
T : (x, y) → (x - 3, y - 1)
We know that the x-coordinate of our image is 4 and its y-coordinate is 3.
Replacing values:
(4 - 3, 3 - 1)
(1, 2)
We can conclude that our pre-image is the point (1, 2).
Final answer:
The preimage of the point (4, 3) under the transformation T : (x, y) → (x + 3, y + 1) is (1, 2), found by reversing the transformation.
Explanation:
The transformation T : (x, y) → (x + 3, y + 1) maps each point in the plane to a new point that is 3 units to the right and 1 unit up from the original point. Finding the preimage of the point (4, 3) means determining which original point would be mapped to (4, 3) by this transformation. To do this, we set up the equations x + 3 = 4 and y + 1 = 3 and solve for x and y. Solving these equations gives us the preimage (1, 2).
Here's the step-by-step math:
Set up the equations based on the transformation T:
x + 3 = 4
y + 1 = 3
Solve for x:
x = 4 - 3 = 1
Solve for y:
y = 3 - 1 = 2
Therefore, the preimage of the point (4, 3) under the given transformation is (1, 2).

2x - 5 = x - 7
and i need the steps to solve the problem
2x - 5 = x - 7
First, let's subtract x from both sides:
2x - x - 5 = x - x - 7
x - 5 = -7
Now, let's add 5 to both sides:
x - 5 + 5 = -7 + 5
x = -2
Answer:
x = -2
Step-by-step explanation:
2x - 5 = x - 7
2x - x - 5 = -7
2x - x = -7 + 5
Now we have isolated x
2x - x = 5 - 7
2x - x = -2
x = -2
Marco buys a certain brand of shampoo for a supplier $7.25 per bottle he sells it to his customers at a makeup 25% what would the makeup be
Answer:
Markup= 1.81
Sale price =9.06
Step-by-step explanation:
The markup is the original prices times the markup rate
markup = 7.25 * 25%
= 7.25 * .25
=1.8125
We round this to the nearest cent
=1.81
The new sale price will be the original price + the markup
7.25+1.81
9.06
Answer:
9.06, or real explanation.
Step-by-step explanation:
"Marco buys a certain brand of shampoo for a supplier $7.25 per bottle he sells it to his customers at a makeup 25% what would the makeup be"
I am going to assume makeup is supposed to be markup, but I will answer all there is.
To find how much higher he charges people for the shampoo, we can multiply the original cost by the percent of increase, so in our case 7.25*.25
7.25*.25=1.8125, or $1.81
1.8125 is the total extra he charges people for the soap.
NOW FOR THE TOTAL COST-------------------
For the total cost we take the original + the added cost
1.8125+7.25=9.0625, or 9.06

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.

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°.
