y = f(2x)  ⇒ Shrink the graph of function f(X) by half horizontally .

What is function and example?

A function is a type of rule that produces one output for a single input.This is represented by the equation y=x2. Any input for x results in a single output for y. Considering that x is the input value, we would state that y is a function of x.Four main categories can be used to classify various types of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element.

y = f((1/2)x)) ⇒ Stretch the graph of f(x) horizontally by factor 2 .

y=2f(2x)  ⇒ Shrink the graph of f(X) by half horizontally .

Which of the following transformations would make corresponding line segments between a pre-image and image not be parallel?

Answers

The transformation of rotating 90° around a point not on the line segment would make corresponding line segments between a pre-image and image not be parallel.

We have a line segment.(a) Suppose we have another line parallel to the given line segment. If we take the reflection of the line segment over the line, it will result in a parallel line segment only.(b) Suppose we have an arbitrary point which is not on the line segment. We rotate the line segment by an angle of 90° about the point. This will change the direction of the line segment.(c) If we translate the line segment in a direction perpendicular to the line segment, it will just change its position, but it will still remain parallel.(d) Suppose we have an arbitrary point which is not on the line segment. We rotate the line segment by an angle of 180° about the point. This will make the line segment again parallel to what it was before.

algebra 1. g(x)=x^{2}-x, g(3b)

Answers

The output value of g( 3b ) in the function g( x ) = x² - x is 9b² - 3b.

What is the value of g( 3b ) in the function?

A function is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.

Given the data in the question;

g( x ) = x² - xg( 3b ) = ?

To determine the output value of g( 3b ), replace all the occurrence of x with 3b in the function and simplify.

g( x ) = x² - x

g( 3b ) = (3b)² - 3b

Apply product rule

g( 3b ) = 3²b² - 3b

Raise 3 to the power of 2

g( 3b ) = 9b² - 3b

if you placed $5 into an account that paid interest at a rate of 5%, and compounded interest yearly, how much would that account be worth in 100 years

Answers

After adding interest the sum would be worth $657.51 .

Interest is the amount paid over and above the original amount to a lender or depositor by a borrower or deposit-taking financial institution at a predetermined rate in the domains of finance and economics (the amount borrowed).

Interest differs from any fees the borrower may be required to pay to the lender or another party.interest also contrasts from a dividend, which is cash distributed to shareholders (owners) by a corporation from its profit or reserve, but not at a predefined rate or proportionally; rather, it is a portion of the reward or interest gained by risk-taking businessmen when revenue is made that surpasses all expenditures.

Interest when the principal is $5 , time is 100 years and rate is 5%.

We know that from compound interest:

Amount = principal (1 + rate)ⁿ

Therefore

Amount = 5 (1 +0.05)¹⁰⁰

Amount = $657.5062...

Amount ≈ $657.51

Therefore adding interest the sum would be worth $657.51

3.48; The line of best fit underpredicts the temperature change.

Answers

Answer:  Choice D

residual = 3.48

The line of best fit underpredicts the temperature change.

============================================================

Explanation:

If s = 1.3, then ŷ is...

ŷ = -2.6s + 1.1

ŷ = -2.6*1.3 + 1.1

ŷ = -2.28

This is the estimated or predicted y value based on the input s = 1.3

Let's now compute the residual

e = residual error

e = (observed y value) - (predicted y value)

e = y - ŷ

e = 1.2 - (-2.28)

e = 1.2 + 2.28

e = 3.48 is the residual

A positive residual means that the predicted y value, aka ŷ, is an underestimate compared to the true observed value. In other words, the observed y value is higher than the ŷ value. Therefore, the line of best fit under-predicts the temperature change.

Find WI if IE = 3
EW and YG are medians of AXYW

Answers

Based on the median and the centroid theorem, the length of WI is 6 units.

What is the Median of a Triangle?

The line that joins the vertex of a triangle to the midpoint of the side it is directly opposite is called the median of a triangle.

According to the centroid theorem, since J is the centroid of triangle XYW, then:

the length of IE is 1/3 of the length of segment EW.

Thus, the equation that relates the length of the segments is;

IE = 1/3(EW)

Given that:

IE = 3 units

Now Substitute the value of IE into the equation:

3 = 1/3(EW)

3(3) = EW

9 = EW

EW = 9 units

Therefore:

The Length of WI = the length of EW - the length of IE

Substitute;

Length of WI = 9 - 3

Length of WI = 6 units.

can someone pls explain to me how to find y intercept

Answers

Answer:

(0, -5)

Explanation:

The function is represented by f(x), and the line graphed would be y= f(x). In slope-intercept form, the equation of a line is given by y= mx +c, where m is the slope and c is the y-intercept.

Since we know that the line is linear, any two points along the line would give us the same slope value. Since y-intercepts occur at x= 0, let the y-intercept be (0, y).

[tex]\boxed{ \text{slope} = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

Slope between (-3, 1) and (1, -7)= slope between (-3, 1) and (0, y)

[tex] \frac{1 - ( -7 )}{ - 3 - 1} = \frac{y - 1}{0 - ( - 3)} [/tex]

[tex] \frac{1 + 7}{ - 4} = \frac{y - 1}{0 + 3} [/tex]

[tex] \frac{8}{ - 4} = \frac{y - 1}{3} [/tex]

[tex] - 2 = \frac{y - 1}{3} [/tex]

Multiply both sides by 3:

-2(3)= y- 1

-6= y -1

Add 1 to both sides:

y= -6 +1

y= -5

Thus, the y-intercept is (0, -5).

__________

Based on the image, however, we are to find the equation of the linear function in slope-intercept form.

The first step would be to find the slope between any two points, which would be -2. This is found using the slope formula, and we have calculated it above.

Substitute the value of the slope into y= mx +c:

y= -2x +c

The y-intercept can be found by substituting a pair of coordinates the line passes through.

When x= -3, y= 1,

1= -2(-3) +c

1= 6 +c

c= 1 -6

c= 5

Thus, the equation of the line is y= -2x +5.

PLEASE MARK AS BRAINLIEST IF YOU FOUND IT HELPFUL BECAUSE IT MAKES ME FEEL GOOD!

Step-by-step explanation:

Linear Standard Form

y = mx + c;

The m equals the change in y divided by the change in x. If you choose left to right for y then you must do the same for x as well.

Δy = ( - 7 ) - ( - 15 ); Δx = 1 - 5;

Δy = - 7 + 15;

Δy = 8;

Δx = - 4;

m = 8 / - 4;

m = - 2;

y = - 2x + c;

Point Substitution

Pick a point (x, y) and sub it into the equation. Make sure to use brackets when subbing.

- 7 = - 2( 1 ) + c;

- 7 = - 2 + c;

Add 2 to both sides.

- 7 + 2 = - 2 + 2 + c;

- 5 = c;

c = - 5;

The c is the intercept.

the greatest common divisor of two integers is $(x 2)$ and their least common multiple is $x(x 2)$, where $x$ is a positive integer. if one of the integers is 24, what is the smallest possible value of the other one?

Answers

The greatest common divisor (24,6) is 6 and the least common multiple (24,6) is 24.

As per the question statement, the greatest common divisor of two integers is (x+2) and the least common multiple x(x+2). It is given that one of the integers is 24.

Let us assume that "b" is the value of other one.

greatest common divisor(24,b) = (x+2)

least common multiple(24,b) = x(x+2)

Formula:

greatest common divisor(24,b)*least common multiple(24,b) = 24*b

24*b = (x+2)*x(x+2)

[tex]b = \frac{x(x+2)^{2} }{24} \\[/tex]

The sedan gets 1090 miles per gallon on average, according to the ratio equation.

What exactly is a ratio?

A ratio is an ordered pair of numbers a and b, denoted by the a / b, where b is not equal to zero.

What is a ratio example?

If there are eight oranges and six lemons in a bowl of fruit, the orange-to-lemon ratio is eight to six.

Given: When the gas tank is 75% full, the mileage is recorded as 15,121.

A sedan tank is typically 18.5 gallons in size. So it holds 13.875 gallons of gas if it is 75% full. If it traveled 15,121 miles, the mileage per gallon is 1090, rounded to the nearest whole number.

The calculation of miles per gallon using the ratio equation:

Let, x = miles per gallon

15121:13.875 is the ratio.

x/1= 15121/13.875

13.875x = 15121

x = 15121/13.875
