Answer:
The y-intercept is -4.
Step-by-step explanation:
The y-intercept in a linear equation is always the b value. In this case, it is -4.
Stephanie and Bryson both grow tomatoes to sell at farmers' markets. Stephanie grew a total of 70 pounds
of tomatoes to sell. She plans to sell the tomatoes for $3.50 per pound. The equation below represents the
profit in dollars, f(x), she will earn by selling x pounds of the tomatoes.
f(x) = 3.50x -110
Bryson plans to sell his tomatoes at a different farmers' market. He grew a total of 90 pounds of tomatoes.
The table below shows the profit, in dollars, he will earn by selling different numbers of pounds of
tomatoes.

Answer:
See below
Step-by-step explanation:
Stephanie's profit relationship:
f(x) = 3.50x - 110Bryson's Tomato Sales, using the pairs of numbers let's find the relationship.
(10, -97.50) and (20, -55.00)Since it is also linear relationship, we'll find a slope and y-intercept:
m = (-55 - (-97.50))/(20 - 10) = 42.50/10 = 4.25y-intercept is:
-97.50 = 4.25*10 + b ⇒ b = -97.50 - 42.50 = - 140So the function is:
g(x) = 4.25x - 140Comparing the functions:
f(x) = 3.50 - 110g(x) = 4.25 - 140The slope of g(x) is greater than f(x) but the y-intercept is smaller
It translates as:
Bryson sells tomatoes at greater price: 4.25 vs 3.50 per poundStephanie needs to sell 110/3.5 = 31.4 pounds of tomatoes before making any profitBryson needs to sell 140/4.25 = 32.9 pounds of tomatoes before making any profitthe perimeter of an equilateral triangle is 8 inches more than the perimeter of a square, and the side of the triangle is 5 inches longer than the side of the square. Find the side of the triangle
Answer:
An equilateral triangle has all 3 sides the same length
If one side of the triangle has length x, the perimeter = 3x
If one side of the square is 5 less than a side of the triangle
then the square has side length x-5 and perimeter 4(x-5) = 4x-20
Since the perimeter of the triangle is 7 more than
the perimeter of the square then our equation is:
3x = 4x-20+7
3x = 4x-13
x = 13
The sides of the triangle are 13 inches
The sides of the square are 13-5=8 inches

Explanation:
It is hard to tell what sort of axioms or theorems you might have available to invoke for this proof. Here, we'll assume that you can use the fact that the sine function of acute angles maintains ordering:
sin(a) > sin(b) iff a > b . . . . . where 0 ≤ a, b ≤ 90°
__
Draw altitude TX, where X lies on RS. The sine relation tells you ...
TX/TS = sin(∠S)
TX/TR = sin(∠R)
Dividing the second equation by the first, we have ...
sin(∠R)/sin(∠S) = (TX/TR)/(TX/TS) = TS/TR
Given that ∠R > ∠S, we know sin(∠R) > sin(∠S), so we have ...
sin(∠R)/sin(∠S) = TS/TR > 1
TS > TR . . . . multiplying by TR

Step-by-step explanation:
At Yvonne's auto dealing, car washes cost $5 for any time up to 10 minutes, plus $ .40 per minute after that. The managers at Yvonne's are trying to agree on a formula for calculating the cost c for a t-minute car wash. Sid thinks c = 0.4t + 5 is correct. Is he correct?
Answer:
He is incorrect
Step-by-step explanation:
Here, given the charge at the auto dealing, we want to know if the formula the managers came up with is correct
The base fee is $5 for 10 minutes or less
Now for any extra minute after the tenth, $0.5 will be paid
So for a t-minute wash, the amount to be paid will be;
C = $5 + 0.4( t- 10) = 5 + 0.4t - 4 = 1 + 0.4t
If t < 10 , C = $5
If t > 10, C = 1 + 0.4t
Sid is incorrect

I need help FAST; It is the end of the semester (at 11:59pm) and I cannot fail.
1. Miss Firkin is selling her Nike Air Force Ones. She bought them online for $75.00, but they were too big for her and she's tripping all over herself (scuffing the tips). She needs to make some extra money to buy Halloween candy....She wants to mark up the sneakers 150%. What is she charging for them?
2. Miss Firkin went to Wal-Mart and iced cupcakes that were $12.99 a box had a sticker that said 30% off. How much is one box?
What did she pay for 3 boxes?
3. Now, what if the cupcakes are taxed as fast food items at a rate of 9%?
4. How much does she now spend on the 3 boxes?
5. Gas was $1.25 per gallon. Now it is $1.38 per gallon. What percent did it increase by? (really not that tricky)
1. I beleive it would be 187,5$, 75.00 + 150% = 187,5.
2. if rounding it would be 9.1$ she had to pay for one times 3 would be 27.3 for three boxes.
3. Not sure what this question is asking but I'll try my best so here: 27.3 +9% × 3 = 89.271 rounded would be 90$
4. 90$ if I did that correctly
5. 1.38 - 1.25 = 0.13 which I beleive would be 13%
0.13 as a percent woudl be 13%

Seat belt use in a state was estimated at %, which means % of people use their seat belts. Suppose two independent drivers have been randomly selected. a. What is the probability that both of them are using a seatbelt? b. What is the probability that neither of them is using a seatbelt? c. What is the probability that at least one is using a seatbelt? a. The probability that both of them are using a seatbelt is 0.3. (Type an integer or a decimal. Do not round.)
Question
Seat belt use in a state was estimated at 89%,
which means 89 % of people use their seat belts. Suppose two independent drivers have been randomly selected.
a. What is the probability that both of them are using aseatbelt?
b. What is the probability that neither of them is using aseatbelt?
c. What is the probability that at least one is using aseatbelt?
The probability that both of them are using a seatbelt is ?
Answer:
a
[tex]P(B) = 0.7921[/tex]
b
[tex]P(B)' = 0.0121[/tex]
c
[tex]P(K) = 0.9879[/tex]
Step-by-step explanation:
From the question we are told that
The proportion of seat belt use is p = 0.89
The sample size n = 2
Generally the probability that both drivers are wearing seat belt is mathematically represented as
[tex]P(B) = (p)^n[/tex]
=> [tex]P(B) = (0.89 )^2[/tex]
=> [tex]P(B) = 0.7921[/tex]
Generally the probability that neither of the two drivers are wearing seat belt is
[tex]P(B)' = (1 - p)^2[/tex]
=> [tex]P(B)' = (1 - 0.89)^2[/tex]
=> [tex]P(B)' = 0.0121[/tex]
Generally the probability that at least one of the drivers is wearing a seat belt is
[tex]P(K) = 1 - P(B)'[/tex]
=> [tex]P(K) = 1 - 0.0121[/tex]
=> [tex]P(K) = 0.9879[/tex]
There are 4 ducks to 6 geese. There are 6 ducks to 8 geese. There are 8 ducs to 10 geese. What does the function show?
Answer: +2 more geese
Step-by-step explanation:
We see that we have to add 2 for each of these:
4 + 2 = 6
6 + 2 = 8
8 + 2 = 10

The sum of two numbers is 63. The larger number is three more than four times the smaller number. Find both numbers.
Last night, he washed 4 plates in 2 minutes. Tonight, his grandparents are coming to dinner, and Rick will wash 6 plates.
If he washes plates at the same rate, how many minutes will it take Rick to wash the plates tonight?
Answer:
id say about 3 minutes.
Step-by-step explanation:
if he washed 4 plates in 2 mins u would divide 4 by 2 and you'd get 2..aka half of a minute which is 30 seconds . so 30×6 is 180 which is 3 minutes
Answer:
3 minutes
Step-by-step explanation:
4 plates in 2 minutes
So, 1 plate in 1/2 minute
6 plates in 1/2 * 6 = 3 minutes

The value of a car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was 1000? 5000? 5020? X dollars?
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Decrease in value= 15%
To calculate the value after one year, we need to use the following formula:
New value= current value/1.15
For $1,000:
New value= 1,000/1.15= $869.57
For $5,000:
New value= 5,000/1.15= $4,347.83
For $5,020:
New value= 5,020/1.15= $4,465.22

(2x - 3)(x + 4) = 2x2 +____ - 12
Answer:
2x^2 + 5x - 12
Step-by-step explanation:
To distribute these two factors, use FOIL(First, Outer, Inner, Last) in this order.
(2x - 3)(x + 4) = 2x(x+4) - 3(x+4) = 2x^2 + 8x - 3x - 12 = 2x^2 + 5x - 12 .
(2x - 3)(x + 4) =
(2x * x) + (2x * 4) + (-3 * x) + (-3 * 4)
