Use the vertical-line test to determine whether each graph represents a function.
Answer:
14) Not a function 15) Function 16) Function
Step-by-step explanation:
The vertical line test is when you draw a line on the graph to see if it passes the function. The rule is that you can only have one intersection per line
for number 14, if you draw a line, it intersects the function twice each time
for 15, no matter what kind of vertical line you draw, each line will only intersect the function once and the same for 16 (except 16 is more of a linear function)
Answer:
Well a function can’t be on the same one as each other so thats why the vertical line test is used.
For number 14 if you’d draw a vertical line, you’d see there would be 2 answers So that can’t be a function.
For number 15, if you draw a vertical line, none of the given have 2 questions so number 15 is a function.
Whilst in number 16 if you’d draw a vertical line, there wouldn’t be anything that have 2 answers of that overlap. So it is a function

Greg and George bought shoes at a local store. Greg bought one dress shoe and 4 sneakers and spent less than $400.
George bought one dress shoe and 6 sneakers and spent more than $400.
Inequality signs < and > denote less than and greater than respectively.
To solve the above inequalities in order to find x and y prices, a pair of solutions will be the result since linear inequalities with two variables will have a range of solutions
In other words, to find x and y for the inequalities we find a point (x,y) that satisfies the inequality.
Example: if the price of a dress shoe is $80 and the price of a sneaker is $60, it satisfies the system of inequalities for Greg and George since their shoe expenses stay below and above $400 respectively.
We could then say that the point (80,60) is one of the solutions to the inequalities.
We could graph the inequalities in order to find points on the graph that satisfy the inequalities. To graph the inequality we make the equation a linear equation x+4y=400 and plot a straight line in accordance to the inequality. All points above the line satisfy George's inequality and vice versa.

A line passes through the points (4, 4) and (6, 10). What is its equation in slope-intercept form?
Answer:
3x-8
Step-by-step explanation:
math
Answer:
y=3x-8
Step-by-step explanation:
The slope of this is the rise over the run. Using the points, we can do (10-4)/(6-4) to get the slope. After solving this, we get 3 as the slope! Slope intercept form is in y=mx+b where m is the slope and b is the y-intercept.
So, y=3x+b
We can insert any of those coordinates into this equation and solve for b to get the y-intercept. If we insert (4,4), then we get 4=3(4)+b
: 4=12+b
:-8=b
Now that we have -8 as the y-intercept, we can insert that as b to get y=3x-8 as the equation in slope intercept form.

Answer:
x = 21 and both sides are 53 units long
Step-by-step explanation:
They are congruent, so they are equal, so
3x-10=x+32 then solve for x
2x=42
x=21
then plug x into each side to get its length
3x-10=3(21)-10=53
x+32=21+32=53
You would expect them to be the same since they are congruent

The absolute measurement specifies the magnitude of the difference
which may be positive or negative.
The completed table is presented as follows;
[tex]\begin{tabular}{|l|c|c|c|}&\textbf{Apple}&\textbf{Grapefruit}&\textbf{Watermelon}\\\textbf{Keiko's measurement}&15 cm&24 cm& \underline{81 cm}\\\textbf{Actual measurement}&\underline{10 cm}&30 cm&90 cm\\\textbf{Absolute difference}&5 cm&\underline{6 cm}&9 cm\\\textbf{Percent error}&\underline{50\%}&\underline{20\%}&\underline{10\%}\end{array}\right][/tex]
Reasons:
The formulas for the inputs in the table are;
Absolute difference = Keiko's measurement - Actual measurement
The difference between Keiko's measurement and the actual measurement can be positive or negative while the absolute difference is always positive
[tex]\displaystyle Percent \ error = \mathbf{\frac{Keiko's \ measurement - Actual \ measurement}{Actual \ measurement} \times 100}[/tex]
Therefore;
[tex]\displaystyle Percent \ error = \frac{ \mathbf{Absolute \ difference}}{Actual \ measurement} \times 100[/tex]
Which gives for Apple;
The actual measurement for Apple = 15 cm - 5 cm = 10 cm
[tex]\displaystyle Percent \ error \ for \ Apple = \frac{5 \, cm}{10 \, cm} \times 100 = \mathbf{50\%}[/tex]
Grapefruit column of the table;
Absolute difference for Grapefruit = |24 cm - 30 cm| = |-6 cm| = 6 cm
The absolute difference for Grapefruit = 6 cm
[tex]\displaystyle Percent \ error \ for \ Grapefruit = \mathbf{\frac{6 \, cm}{30 \, cm} \times 100} = 20\%[/tex]
Percent error for Grapefruit = 20%
Watermelon column of the table;
Keiko's measurement = Absolute difference + Actual measurement
Using the given options, we have, 90 - 9 = 81
Therefore, the difference = -9, while the absolute difference = 9
Keiko's measurement for Watermelon = 90 cm - 9 cm = 81 cm
[tex]\displaystyle Percent \ error \ for \ Grapefruit= \frac{9 \, cm}{90 \, cm} \times 100 = 10\%[/tex]
The completed table is as follows;
[tex]\begin{tabular}{|l|c|c|c|}&\textbf{Apple}&\textbf{Grapefruit}&\textbf{Watermelon}\\\textbf{Keiko's measurement}&15 cm&24 cm& \underline{81 cm}\\\textbf{Actual measurement}&\underline{10 cm}&30 cm&90 cm\\\textbf{Absolute difference}&5 cm&\underline{6 cm}&9 cm\\\textbf{Percent error}&\underline{50\%}&\underline{20\%}&\underline{10\%}\end{array}\right][/tex]

Since there is a right angle, this is a right-angled triangle and we can solve for x using Pythagoras Theorem that goes [tex]a^2+b^2=c^2[/tex], where c is the hypotenuse (longest side of the triangle).
In this case, x would be the c.

Find an equation of the line passing through the point (2, 7) with slope m= 6.
Answer:
y - 7 = 6(x - 2)
Step-by-step explanation:
1. Since we're given one point and the slope of a line, we can use the point slope form: [tex]y-y_1=m(x-x_1)[/tex]
m = slopey_1 = first y-coordinatex_1 = first x-coordinate2. (Plugging in values)
[tex]y-7=m(x-x_1)[/tex] [tex]y-7=6(x-x_1)[/tex] [tex]y-7=6(x-2)[/tex]Therefore, one equation of the line is y - 7 = 6(x - 2).
Choose the steeper line.
y=1/2x-3
or
y=1/4x -8
Hello there!
y=1/2x-3 is steeper than y=1/4x-8
The bigger the slope, the steeper the line.
