find the value of x so that f(x)=7

The answer is:

x = 5

The value of x such that f(x) = 7 is 5.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given a graph of a function f(x).

The graph is a straight line where there is a unique value of y for each value of x.

We have to calculate the value of x when y = 7.

Taking the y coordinate to 7, the x coordinate corresponding to the y coordinate is 5.

Hence the value of x is 5.

Answer:

Steve is first

Step-by-step explanation:

Steve is first in the ratio if the ratio of guitars is 4:3.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other. A set of data points can be used to observe the constant relationship. A set of data with a constant relationship between two values is a comparison of miles traveled to hours traveled. A special type of ratio is the comparison of two different quantities.

The general form of expressing a ratio between two quantities say 'a' and 'b' is a: b

Jenny has 3 guitars. Steve has 4 guitars.

The ratio is 4:3, which represents 4/3 or 4 parts Steve to 3 parts Jenny.

Hence, Steve is first in the ratio.

Answer:

y= -4/5x+33/5

Step-by-step explanation:

for questions like these, the slope is always defined as the change in y over the change in x or use the equation m=y2-y1/x2-x1.

x1=7 and y1=1

x2=-3 and y2=9

now plug these numbers in to the equation. m= 9-1 / -3-7 Or m= 8/-10 simplified to m= -4/5

now that we have the slope you can plug it in to the equation y=mx+b and get y= -4/5 + b.

to find b, the y-intercept, you can use either of the two points and the answer will be the same. for this one, I'll use (7,1).

1= -4/5 x 7+b. b= 33/5

Answer:

Simson paradox

Step-by-step explanation:

In Simpson paradox, the trend that appears in the combined data reverses or disappears in the results of the several individual groups that make up the combined data

In the question, given that the percentage of female applicants accepted = 44% while the percentage of male applicants = 56%, and that the private company found that each department accepted a greater percentage of females over males

The above claim can occur when there is a confounding variable, which is the number of applications from female or male

The percentage used or the data provided to by the private company in each department are percentage in proportion of number of accepted females to total number of female applicants and percentage in proportion of number of accepted males to total number of male applicants, whereby, when there are fewer number of female applicants to each department and more were accepted, their percentage will be larger than the percentage of the male applications that have a lower percentage but larger number of applications, such that the accepted male applicants still outnumber the female when that total number of applications are considered.

Answer:the answer -8x-9y=-17

16x-4y=12

Step-by-step explanation:

divide 16x-4y=12 with 2

8x-2y=12

Then add the equations

-8x-9y=-17

8x-2y=12

0-11y=-23

You can’t do this with the other equations provided.

Answer:

9) x=3

10)x=8.5

Step-by-step explanation:

Because M is a midpoint, for both questions, the equations on M's either sides are equal.

9) 5x+9=24

Subtract 9 from both sides

5x=15

Divide by 5 on both sides

x=3

10) 3x-7=x+10

Add 7 to both sides and subtract x from both sides

2x=17

Divide by 2

x=8.5

Answer:

infinate solution

Step-by-step explanation:

8(x - 2) + 9 < 3(x - 1) + 5x

Distribute

8x - 16 + 9 < 3x - 3 + 5x

Combine like terms

8x - 7 < 8x - 3

Subtract 8x to both sides

-7 < -3

Since -7 is less than -3, there are many infinitely solutions to this equation.

Rational number

Answers:

The relation is a function

Domain = {-2, -1, 0, 1, 2}

Range = {-2, 0, 2}

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

Explanation:

The blue points shown are

(-2,-2)

(-1,0)

(0,2)

(1,0)

(2,-2)

Note how the x values do not repeat themselves. Visually this graph passes the vertical line test. It is impossible to draw a single straight vertical line through more than one blue point at a time. It tells us that any x input leads to exactly one y output.

The relation is a function

The domain is the set of x coordinates of the points

Domain = {-2, -1, 0, 1, 2}

The range is the set of y coordinates of each point

Range = {-2, 0, 2}

Toss out any duplicate items that may occur in the range.

Answer:

The relation is a function.

The domains are 2, 1, 0, -1, -2.

The ranges are -2, 0, 2, 0, -2

A'(1, -4)

B'(3, 2)

C'(4. -2)

Step-by-step explanation:

Given

Triangle ABC with coordinates

A(1, 4), B(3, -2), C(4, 2)

To find

Coordinates of the image A'B'C' after a reflection over the x-axis

Solution

Rule for reflection over x-axis is

R(x) = (x, y) → (x, -y)

The coordinates will change as follows

A(1, 4) → A'(1, -4)

B(3, -2) → B'(3, 2)

C(4, 2) → C'(4. -2)

Answer:

Total interest = A - P = $2,223.00

Total amount = $10,023.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 9.5%/100 = 0.095 per year.

Solving our equation:

A = 7800(1 + (0.095 × 3)) = 10023

A = $10,023.00

The total amount accrued, principal plus interest, from simple interest on a principal of $7,800.00 at a rate of 9.5% per year for 3 years is $10,023.00.

Answer:

a geometric transformation would mean to make some changes in any given geometric shape. In geometry, transformations relate to the movement of figures on a plane. Each transformation follow a rule

Step-by-step explanation:

For example 4 to the felt and 3 to the top, (x,y) (x-4, y+3)

2 down and 4 to the right, (x.y) (x-2, y+4)

Basically if you see an image on a graph, its the preimage and you need to create the new image the same size and shape as the the original.
