Given the function f(x) = 2x + 5, what would the input be with an output of 21

1. horizontal shrink by factor of 2/3 means multiply outside the f(x) or outside the x^2 by 2/3:

   (2/3)•f(x)

2. translation left 5 units means "x+5" inside:

   (2/3) • f(x+5)

3. tranlate down 2 units means "-2" outside:

      (2/3) • f(x+5) -2

or    (2/3) (x+5)^2 - 2

[tex]\frac{2}{3}\cdot f(x+5)-2[/tex]   or   [tex]\frac{2}{3}\cdot (x+5)^2-2[/tex]

Answer:

X = 7

Step-by-step explanation:

because of you do 5+2 = 7 then you minus 3 which you get 4.

the. if you have a production of around 10 you will get 7.

or you can do.

3+2 which is 5 and then you multiply that by 2 which is 10 and then you comprised that number therefore you will get 6 but you have to find X so we youndelie (think that's how u spell it) X which will equal to 1 and 6+1 is 7. once you get it it's quite simple

Answer:

The slope of f(x) is equal to the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).

Step-by-step explanation:

F(x) is already given to you on the graph. You need to plot the x and g(x) graph. (remember g(x) is just a fancy way of saying y)

Once this line is plotted, you will see that f(x) and g(x) are parallel to one another. G(x) is below f(x), so its y-intercept is lower.

Answer:

y= 2x - 11

Step-by-step explanation:

(-7 +1 )/ (2-5) = 2

y= 2x +b

-1 = 2* 5 + b

solve for b and you get -11 so the equation of the line is :

y = 2x -11

Answer:

It should be 4.

The inequality expression of the statement is |2s - 7| >= -1

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

The mathematical statement is given as

|2s - 7| is bigger than or equal to -1

The term "bigger than or equal" means greater than or equal to

In mathematics, the term greater than or equal to is represented as >=

So, we have the representation of the mathematical statement to be

|2s - 7| >= -1

From the question, we are not instructed to simplify the expression

This means that we leave the expression |2s - 7| >= -1 unsimplified

Hence, the mathematical statement as an expression is |2s - 7| >= -1

1. to divide 3 by 4,500.

after dividing 3 and 4,500 you get

1,500

The money he will make over a five-month period will be $7,500.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

A rec center worker procures a similar sum every month. In the wake of laboring for a considerable length of time, he procured $4,500.

The amount of money that he earns each month is given as,

⇒ $4,500 / 3

⇒ $1,500 per month

Then the money he will make over a five-month period will be given as,

⇒ $1,500 x 5

⇒ $7,500

The money he will make over a five-month period will be $7,500.

Answer:

Perpendicular

Step-by-step explanation:

Both lines intersect and form a right angle when they intersected each other. Non co-planar means essentially means "on different planes", but both lines do lie on the same plane. Parallel lines don't intersect at all! However lines a and d are intersecting. Skewed means neither parallel nor perpendicular (meaning they intersect and don't form a right angle).

Answer:

It would be perpendicular.

Step-by-step explanation:

Perpendicular lines form a 90-degree angle.

Skew lines are on different planes and do not intersect.

Since A and D intersect with a 90-degree angle they're perpendicular.

18,000 lbs

Step-by-step explanation:

Assuming the table attached with C in inches and S in pounds, we see that the first differences in S are ...

 180, 540, 900

These are not constant, so the relation is not linear.

Second differences are ...

 360, 360

These are constant, so the relation is quadratic. With a short trial, we find that a suitable equation is ...

 S = 180·C²

The safe load for C=10 is then ...

 S = 180·10² = 18,000 . . . pounds

Step-by-step explanation:

Answer:

x-intercept: (-4, 0)

y-intercept: (0, 6)

Step-by-step explanation:

4y - 6x = 24

To find the x-intercept, set the y value equal to 0.

4(0) - 6x = 24

Simplify by removing 4(0) since it just equals 0.

-6x = 24

Divide both sides of the equation by -6

x = -4

Since we set y equal to 0 and we know that the x value is -4, we can create a coordinate for the x-intercept of the equation.

(x, y) = (-4, 0)

Repeat the process for finding the y-intercept, but set x equal to 0.

4y - 6(0) = 24

4y - 0 = 24

4y = 24

Divide both sides of the equation by 4

y = 6

Write as a coordinate/intercept.

(x, y) = (0, 6)
