find the value of x so that f(x)=7.
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.
What is Function?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.

Jenny has 3 guitars. Steve has 4 guitars. If the
ratio of guitars is 4:3, who is first in the ratio?
Answer:
Steve is first
Step-by-step explanation:
Steve is first in the ratio if the ratio of guitars is 4:3.
What is Ratio?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.

Solve the inequality.
8(x – 2) + 9 < 3(x – 1) + 5x
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.

Which of the following is the best example of a system of equations that should be solved by the elimination method?
Question 2 options:
8x + 3y = 2
5x + 8y = -11
2x - 4y = -16
y = 5x + 13
-8x - 9y = -17
16x - 4y = 12
12x + 7y = -17
9x + 11y = -7
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

What is an equation in point slope form of the line that passes through (7, 1) and (-3,9)
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:
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.

(PLEASE ANSWER ILL GIVE YOU 20 POINTS) Determine if the relation is a function. If the relation is a function, find the domain and range.Required to answer. Single choice.
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

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)
A college accepted new applicants, of whom 56% were male and 44% were female. The board of directors was not pleased that males were being accepted at a greater percentage than females. A private company investigated and found each department accepted a greater percentage of females over males. What may make this claim possible?
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.
