Answer:
Only graph X represents a function.
Step-by-step explanation:
Use the vertical line test for testing out if the graph represents a function. If the line passes through two or more points when drawn through a single x value, then it is not a function. The only graph that is a function is graph X.
Because of a heavy spring runoff, the shoreline of a lake increased from 10.0 miles to 13.8 miles. What was the percent of increase
in the shoreline?
Answer:
The percent of increase in the shoreline was 38%.
Step-by-step explanation:
Given that the shoreline increased from 10 miles to 13.8 miles because of the spring runoff, to determine the percentage by which the shoreline increased, the following calculation must be performed:
10 = 100
13.8 = X
((13.8 x 100) / 10) = X
(1,380 / 10) = X
138 = X
Thus, since 138 - 100 is equal to 38, the percentage by which the shoreline increased was 38%.

Tina can grow 2 plants with every seed packet. How many seed packets does Tina need to
have a total of 14 plants in her backyard?
Answer:
7 is the answer
Step-by-step explanation:
2x7=14
Answer:
7
Step-by-step explanation:
14/2 is 7. Every packet is 2 plants. So in order to find the amount of packets, you just needed to divide the amount of seeds per packet from the total she wanted

PLEASE HELPPP Will Give brainliest if it help :) The question : You are at an amusement park with your friend. You spend $11.00 on a stuffed animal
for your little brother. Then you and your friend ride the roller coaster several times
together for $4.00 each. Write a system of linear equations that represents this
situation. Will you and your friend spend the same amount of money? Explain.
Answer:
y= 4x + 11 and no.
Step-by-step explanation:
Because you spent the 11 dollars extra and rode the rides meanwhile your friend only went on the rides. If (x) equals the amount of rides and (y) means the total amount. Then your friends equation with be y= 4x. But, you already spent 11 dollars additionally so therefore your equation with be y=4x + 11.
I hope this helped.
Friend y=4x
You y=4x + 11

How is a system of equations created when each linear function is given as a set of two ordered pairs. Explain
Answer:
Please check the explanation.
Step-by-step explanation:
If each linear function is given as a set of two ordered pairs, all we need is to find a slope between two lines and put one of the points in the slope- intercept form of the line equation to find the y-intercept 'b' and then writing the equation in the slope-intercept form. This is how we can generate a system of equations.
For example, let suppose a linear function has the following ordered pairs:
(1, 1) (2, 3)Finding the slope between two points
[tex]\left(x_1,\:y_1\right)=\left(1,\:1\right),\:\left(x_2,\:y_2\right)=\left(2,\:3\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{3-1}{2-1}[/tex]
[tex]m=2[/tex]
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Now, substituting the slope m = 2 and the point (1, 1) to determine the y-intercept
[tex]y=mx+b[/tex]
[tex]1 = 2(1)+b[/tex]
[tex]b = 1-2[/tex]
[tex]b = -1[/tex]
Now, substituting the slope m = 2 and the value of y-intercept in the slope-intercept form of the line equation
[tex]y=mx+b[/tex]
[tex]y=2x+(-1)[/tex]
[tex]y=2x-1[/tex]
Thus, the equation of a line with the linear function having the points (1, 1) and (2, 3) is:
[tex]y=2x-1[/tex]This is how a system of equations created when each linear function is given as a set of two ordered pairs.
Answer:
Sample response: Use the two points of a linear function to write an equation in slope-intercept form by first finding the slope of the function, and then using a point and the slope to determine the y-intercept. Write the equations in slope-intercept form.

Which is the same function as -3x + 7 = y?
A) f(x) = -3x + 7
B) f(-3x) = 7
C) f(7) = -3x
D) f(x) = -3 + 7
The solution is: A) f(x) = -3x + 7 is the same function as -3x + 7 = y.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
given that,
the function is: -3x + 7 = y
now, we have to find the same function as -3x + 7 = y.
now, let, the function is represented by f(x)
so, we have,
y = f(x)
so, we get,
f(x) = y = -3x + 7
we get,
f(x) = -3x + 7
so, f(x) = -3x + 7 is the same function as -3x + 7 = y.
Hence, A) f(x) = -3x + 7 is the same function as -3x + 7 = y.
