Write the equation of the following graph in intercept form.
Answers
I’ll start with option 2.
(x-2)=0
(add 2 to both sides)
x=2
(x+5)=0
(subtract 5 from both sides
x=-5
Judging by the graph, option 2 has the opposite of the zeroes needed, and thus option 3 will be the correct choice.
If you want to check option 3 further though...
(x+2)=0
x=-2
(x-5)=0
x=5
These are the correct zeroes. Option 3 is correct.

What is parabola equation intercept form?The intercept form of parabola can be expressed using the following expression.
\(f(x)=a(x-p)(x-q)\)
Here, a is the constant, (p, q) are the x-values on the graph, where y is zero.
In the given graph, the point (-2,0) is the point, where the value y is zero. Here, the value of x is -2. Therefore,
\(p=-2\)
The other point, where the value of y is zero is (5,0). Thus the value of q is,
\(q=5\)
The value of constant a is,
\(a=-\dfrac{p}{q}\\a=-\dfrac{-2}{5}\\a=0.4\)
Put these values in the above equation, we get,
\(f(x)=0.4(x+2)(x-5)\)

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

If a car rolled down a 25-meter ramp, continued rolling another 20 meters at the bottom, then reversed and went back to the top of the ramp, what is the car's displacement? What is the car's distance traveled? Explain
I will give brainliest!
Answers
Displacement = 0
Distance = 90
Explanation:
Displacement refers to the overall change an object has made in its position. The car is right back where it started, so the answer is 0.
To calculate total distance, add the distance down the ramp to the additional horizontal distance, then multiply it all by 2 because it made the same journey again in reverse.
25 + 20 = 45
45 x 2 = 90 m
Distance=90
There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish

4. Chris and Keith went to a carnival. Chris started with 80 tickets and spent x tickets at the carnival, Keith started with 140 tickets and spent 2x tickets at the carnival. At the end of the night, they had the same number of tickets left over. How many tickets did Chris spend at the carnival?
Answers
Answer: x=20
Step-by-step explanation:
3x+80=140
3x=60
x=20
Answer: Chris spent 60 tickets at the carnival.
Step-by-step explanation:
At the end of the night, both Chris and Keith had the same amount of tickets, so:
80 - x = 140 - 2x
Now, solve the equation. Start by bringing the -2x to the left side.
80 - x + 2x = 140
Bring the 80 to the right side so the variables are isolated.
-x + 2x = 60
Add like terms.
x = 60
Check the work.
Chris had 80, spent 60, so had 20 left. --> 80 - 60 = 20
Keith had 140, spent 120 (60 *2), so also had 20 left. --> 140 - 120 = 20
So, Chris spent 60 tickets at the carnival.

Answer:
Step-by-step explanation:
you are completely right please follow your heart <3
You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

920000 or 9.2 x 10⁵
Step-by-step explanation:
Given:
It takes the sun 2.3 x 10⁸ years to orbit the milky wayIt takes Pluto 2.5 x 10² years to orbit the sunGiven this we want to find :
How many times pluto orbits the sun over the time span that the sun makes one orbit around the milky wayTo get this we must divide the time it takes Pluto to orbit the sun by the amount of time it takes the sun to orbit the milky way
In other words our answer = 2.3 x 10⁸ / 2.5 x 10² = 920000
We can then convert the outputted number into scientific notation
In doing so we get 9.2 x 10⁵
Its important to note that the coefficient (9.2) must have 2 significant figures as the given numbers do.
All we did to convert to scientific notation is add a decimal in between the two sig figs and multiply (9.2) by 10 to the power of how many decimal places we moved over to get to 9.2. Here we moved the decimal point 5 places from 920000. to get to 9.2 therefore the answer in scientific notation would be 9.2 x 10⁵
(You can easily calculate this by plugging this into a calculator)
SUN
2.3 • 10^8= 230000000
PLUTO
2.5 • 10^2 = 250
DIVIDE SUN BY PLUTO
