How would i know if a line on a graph has passed the vertical line test?
Answer:
The vertical line will only pass the graph line once.
Step-by-step explanation:
For example, I found an example online. The vertical line intersects a circle twice. But on a horizontal squiggly line, it only touches it once. So the circle is NOT a function but the squiggly line IS a function.

Which fraction represents the solution to -6/5/(-3/25) in simplest form?
A. -10
B. -18/125
C. 10
D. 18/125
The fraction represents the solution to (-6/5)/(-3/25) in the simplest form will be 10. Then the correct option is C.
What is Algebra?Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to answer the problem correctly and precisely.
The fraction numbers are given below.
-6/5 and -3/25
Then the division of the numbers -6/5 and -3/25 will be given by putting a division sign between them. Then we have
⇒ (-6/5) ÷ (-3/25)
⇒ (-6/5) / (-3/25)
⇒ (6/5) x (25 / 3)
⇒ 150 / 15
⇒ 10
The part that addresses the answer for (- 6/5)/(- 3/25) in the most straightforward structure will be 10. Then the right choice is C.

My question is in the picture
1. Geneva has 24 points. Then her spin lands on blue. What is her score now? Explain.
Blue = + 4. This means that you will need to add 4 to 24, causing Geneva's new amount of points to be 28. You could put down,
Geneva now has 28 points. Blue is equal to +4, so I added 24 + 4 to get 28.
2. Geneva and Juan start a new game. Each player has 0 points.
a. Geneva's first two spins are yellow and red. What is her score now? Explain.
Geneva's score is now -2. Yellow is equal to -4, red is equal to +2. -4 + 2 = -2.
b. Juan's first two spins are red and green. What is his score now? Explain.
Red is equal to +2 and green is equal to -1. That means that Juan has 1 point because 2 + -1 = 1.
c. Which player has a greater score now? Explain.
Juan has a greater score. He has a greater score because 1 is greater than -2.

In line 2, I replaced r with 2t because the radius r is increasing at a rate of 2 cm per second. So if t is the number of seconds, then 2t is the radius in cm at time t.In line 4, I multiplied both sides by 3 to clear out the fractions. On the next line, I divided both sides by 4pi.kyle has $1.60 in change in his pocket. He has the same number of quarters as nickels. He has 4 more dimes than quarters.

A speed limit is 35 mph. A car is travelling 10 mph over the speed limit. I’d that a sum of 0
Answer:
The car is going 45 mph
Step-by-step explanation:
Since the speed limit is 35 mph and the car is 10 mph over the speed, we can add them to find out how fast the car is going. We can solve 35+10 which will give us 45. So it is not a sum of 0 but instead a sum of 45.

How many solutions does the following equation have?
3x + 7 + 2x = 5x + 7
One. Many. None
Answer:
Infinite/many
Step-by-step explanation:
3x + 7 + 2x = 5x + 7
3x + 2x + 7 = 5x + 7
5x + 7 = 5x + 7
5x - 5x + 7 = 7
7 = 7
Infinite solutions
Answer: many (all real numbers)
Step-by-step explanation:
1) add 2x and 3x to give you 5x
You now have 5x+7=5x+7
2) you can simplify this by subtracting 7 on both sides and dividing by 5
3) you are then left with x=x
Write an equation in slope-intercepts form for the line that passes through (5, -4) and is perpendicular to the line described by 2x-10y=0
EXPLAIN what you did in each step to arrive at your answer plz
Answer:
y = -5x + 21
Step-by-step explanation:
First, put 2x - 10y = 0 into slope intercept form to find the slope:
Subtract 2x from both sides:
-10y = -2x
Divide each side by -10:
-10y = -2x
y = 1/5x
So, the slope of the line is 1/5.
Perpendicular lines have opposite reciprocal slopes, so the slope of the other line will be -5.
Then, use the equation y = mx + b to plug in the slope and the point given.
Solve for b:
y = mx + b
-4 = -5(5) + b
-4 = -25 + b
21 = b
Lastly, plug in the slope and b into y = mx + b to create the equation in slope intercept form:
y = -5x + 21 is the equation

Step-by-step explanation:
My friend Dubble got 10 rews and corazs for about $32. Rews for $2 each and some corazs for $8 each
Answer:
"Dubble" bought 10 rews for $2.00 each and 1 corazs for $8.00 each
-I put quotation marks on Dubble bc i didnt know if it was a boy or girl name sorryyy its.. um.. unique :) -
Step-by-step explanation:
The price for the rews is 10x 2 because the price of each is $2 and he got 10 so he spent $20 on rews.
Then you subtract the total amount of money "Dubble" used buying these things and the amount of money "Dubble" used on the rews which is 32-20=8
The last step is that you divide 8 by the pice of each corazs which is 8 divided by 8 so the answer is 1.
Hope this helped you sorry im a little late bubs.<3

Given FGH with vertices F(-1, 3), G(-5, 1), and H(-3, 5) reflected by Rx-axis
Find the coordinate of vertices F'G'H the image of FGH
1, F(-1, 3), G(-5, 1), and H(-3, 5)
2, F(-1, -3), G(-5, -1), and H(-3, -5)
3, F(1, 3), G(5, 1), and H(3, 5)
4, F(-1, 3), G(-5, 1), and H(-3, -5)
Answer:
Option F is true.
Step-by-step explanation:
The rule of reflection across the x-axis
P(x, y) → P'(x, -y)
For example, when a point P with coordinates (1, 2) is reflected across the x-axis, the coordinates of the image of point P will be: P'(1,-2).
i.e.
P(x, y) → P'(x, -y)
P(1, 2) → P'(1, -2)
Now, given FGH with vertices F(-1, 3), G(-5, 1), and H(-3, 5) reflected by Rx-axis.
Using the rule of reflection across the x-axis
P(x, y) → P'(x, -y)Thus, the coordinate of vertices F'G'H the image of FGH will be:
F(-1, 3) → F'(-1, -3)
G(-5, 1) → G'(-5, -1)
H(-3, 5) → H'(-3, -5)
Hence, option F is true.
