Answer:
y= [tex]\frac{3}{2}[/tex]x -1
Step-by-step explanation:
To find slope I first found the two points on the graph which were (0, -1) and (2, 2). Then I used rise over run to find the slope the point went up 3 units and to the right two units.
then to find the y intercept I found a pint of the graph where the line had passed through the y-intercept line on the graph which just so happened to be -1.

Answer:
y = 3/2 - 1
Step-by-step explanation:
First let's take two coordinates in the line.
( 2 , 2 ) ( 0 , -1)
You can use y = m x + c to find the equation of the line.
Here,
m → slope
c → y - intercept
( 2 , 2 ) ( 0 , -1)
↑ ↑ ↑ ↑
( x1 , y1 ) ( x2 , y2 )
First let's find the slope of the line.
m = ( y1 - y2) / ( x1 - x2)
m = ( 2 - (-1) ) / (2 - 0 )
m = ( 2 + 1 ) / 2
m = 3 / 2
Now let's find the y - intercept of the line.
For that, let's use ( 0 , -1 ) coordinate
y = m x + c
y = 3/2 × 0 - 1
y = 0 - 1
y = ( - 1 )
Therefore, the equation of the line is,
y = 3/2x - 1
Hope this helps you :-)

Keith bought 4 new baseball trading cards to add to his collection. The next day his dog at half of his collection. There is now 25 cards left. How many cards did Keith start with?
Answers
Answer:
46 cards
Step-by-step explanation:
We can use a variable to represent the starting amount of cards: (x)
Keith bought 4 new cards: (+4)
His dog ate half of the collection: (x/2)
There are now 25 cards: (=25)
So we can use this expression to find the starting amount: (x+4)/2=25
Start by multiplying both sides by 2 to get rid of the (x/2).
Now subtract 4 from both sides to get rid of the (+4).
Finally, we know x= 46
Thus, Keith started with 46 cards.
During the first year with a company, Finley was paid an annual salary of $57,000, with a 4% raise for each following year. Which equation represents Finley's annual salary, f (n), during the nth year?
f (n) = 57,000(0.04n – 1)
f (n) = 57,000(1.04n)
f (n) = 57,000(1.04n – 1)
f (n) = 57,000(0.96n)
Answers
Answer:
Step-by-step explanation:
C I took the test
The equation of Finley's annual salary represents 57,000(1.04n – 1) during the nth year.
What is the percentage?The percentage is defined as ratio expressed as a fraction of 100.
Finley was paid an annual salary of $57,000
with a 4% raise for each following year
Finley's annual salary, during the 2th year
⇒ 4% of 57,000 + 57,000
⇒ (0.04)57,000 + 57,000
⇒ 2280 + 57,000
⇒ 59280
Finley's annual salary, during the 2th year
Determine the difference between year 2 and year 1 salary.
Rate of change = 4% of 57,000 - 57,000
Rate of change = (0.04)57,000 - 57,000
Rate of change = 57,000(0.04 - 1)
Finley's annual salary, during the 5th year
Determine the difference between year 5 and year 4 salary
⇒ 57,000(0.04(5) - 1)
That's the constant.
Finley's annual salary, during the nth year
So, f (n) = 57,000(1.04n – 1)
Hence, the equation of Finley's annual salary represents 57,000(1.04n – 1) during the nth year.

the equation p=1.5r graphed find price p, in dollars for r pounds of rice
Answers
Answer:
Hope that help you mark me brinilylist
Step-by-step explanation:
Given that 5 pounds of rice at a store cost $6.50.
Then 1 pound of rice at a store cost = $6.50/5= $1.3
So the equation for the cost can be written as:
C=1.3P just like we write equation y=mx
Now we have to graph the cost C, vs pounds of rice.
Variable for Pounds of rice is not given so let it be "P"
So let's make a table for the number of pounds (P) and cost (C) we can graph the points from that table to get the final graph.
The Attached graph is the final graph.

Anita's, a fast-food chain specializing in hot dogs and garlic fries, keeps track of the proportion of its customers who decide to eat in the restaurant (as opposed to ordering the food "to go"), so it can make decisions regarding the possible construction of in-store play areas, the attendance of its mascot Sammy at the franchise locations, and so on. Anita's reports that 52% of its customers order their food to go. If this proportion is correct, what is the probability that, in a random sample of 5 customers at Anita's, exactly 4 order their food to go?
Round your response to at least three decimal places
Answers
Using the binomial distribution, it is found that there is a 0.1755 = 17.55% probability that, in a random sample of 5 customers at Anita's, exactly 4 order their food to go.
For each customer, there are only two possible outcomes, either they order their food to go, or they do not. The orders of each customer are independent of other customers, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.In this problem:
52% of its customers order their food to go, hence [tex]p = 0.52[/tex].Random sample of 5 customers, hence [tex]n = 5[/tex].The probability that exactly 4 order their food to go is P(X = 4), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 4) = C_{5,4}.(0.52)^{4}.(0.48)^{1} = 0.1755[/tex]
0.1755 = 17.55% probability that, in a random sample of 5 customers at Anita's, exactly 4 order their food to go.

The population of Fantasy City doubles each month. When will the city be half populated if it will be fully populated in 10 months.
Answers
Using an exponential function, it is found that the city will be half populated in 9 months.
The population of Fantasy City doubles each month, hence, after t months, the population is given by:
[tex]P(t) = P(0)2^{t}[/tex]
In which P(0) is the initial population.Fully populated in 10 months, hence, the full population is:
[tex]P(10) = P(0)2^{10} = 1024P(0)[/tex]
Hence, half populated is [tex]P(t) = \frac{1024P(0)}{2} = 512P(0)[/tex], hence:
[tex]P(t) = P(0)2^{t}[/tex]
[tex]512P(0) = P(0)2^{t}[/tex]
[tex]2^t = 512[/tex]
[tex]2^t = 2^9[/tex]
[tex]t = 9[/tex]
The city will be half populated in 9 months.

Answers
5
she gave her sister 5 toys.
Correction to the question - It is not 15 it 1/5th.
According to the given question Cynthia had 25 toys and she gave 1/5th of her toys to her little sister.
So, The total number of toys is 25 to find 1/5th of it we need to multiply the total number of toys she had and the fraction she gave.
(25 x 1/5) = 5. so the number of toys she gave away to her little sister is 5.

13/20 - 1/2
===================================================
Explanation:
Ignore the big X and the shading for now. This figure has 4 rows by 5 columns of rectangles. So there are 4*5 = 20 little rectangles total. Each little rectangle represents 1 brownie.
Then let's say the shaded region represents the amount of brownies Mary receives. We have 13 rectangles shaded in out of the 20 total. This means 13/20 is the fractional amount Mary gets.
She then eats 10 of the 20 total, so she eats 10/20 = 1/2 of the brownies.
Therefore, we end up with the expression 13/20 - 1/2 to represent the fractional amount that Mary still has that she hasn't eaten yet (which is 3/20).
We can say: 13/20 - 1/2 = 13/20 - 10/20 = 3/20

The height of a ball when it is thrown off a cliff can be represented by the equation $h=45-7t-6t^2$, where $t$ is time in seconds. In how many seconds will the ball reach a height of 25 feet?
Answers
You want to find t such that
45 - 7t - 6t² = 25
or
6t² + 7t = 20
Solve for t. By completing the square, we have
6t² + 7t = 20
t² + 7/6 t = 10/3
t² + 7/6 t + (7/12)² = 10/3 + (7/12)²
(t + 7/12)² = 529/144
t + 7/12 = ± 23/12
t = -7/12 ± 23/12
t = -5/2 or t = 4/3
We ignore the negative solution, so the ball reaches a height of 25 feet at t = 4/3 seconds, or about 1.33 seconds after being thrown.

You have now three medals left to unwrap (one in your hand, two on the table). At this point, the host gives you the option to change your mind and swap your medal for one of the two left on the table. What would you do at this point?
