Find the equation of the line in slope-intercept form.Slope is 2/3 through (3, 4)
Answers
Answer:
y = (2/3)x + 2
Step-by-step explanation:
Start with the general slope-intercept form y = mx + b. Substitute 3 for x and 4 for y and 2/3 for m, and find the intercept, b:
4 = (2/3)(3) + b, or 2 = b. Then the desired equation is y = (2/3)x + 2.

Part A Tim wants to buy three pairs of jeans. He compares the prices at a store in his neighborhood and at an online store. He finds that a pair of jeans costs $24 at the local store. If he buys online, each pair would cost $22, and he would have to pay a shipping fee of $6 per order.
Part B Look at the table that represents the local store. For each row in the table, find the ratio of the number of pairs of jeans to the cost of the jeans.
Part C Are the ratios that you calculated in part B equivalent? Based on these ratios, what can you conclude about the relationship between the number of pairs of jeans that Tim buys at the local store and the cost?
Part D Next, look at the table that represents the online store. For each row in the table, find the ratio of the number of pairs of jeans to the cost of the jeans.
Part E Are the ratios that you calculated in part D equivalent? Based on these ratios, what can you conclude about the relationship between the number of pairs of jeans that Tim buys at the online store and the cost?
Part F The local store where Tim shops charges a 7% sales tax for clothing. Complete the table by figuring the cost of the jeans after sales tax is applied. The first row has been done for you.
Part G From part F, find the ratio of the number of pairs of jeans to the cost with sales tax for each row in the table. Part H Are the ratios that you calculated in part G equivalent? Show your work to support your answer. What does this tell you about the relationship between the number of pairs of jeans and the cost with sales tax applied?
Please, I'm giving all of my points for this
Answers
add 24, 22, and 6. for the ratio see if they all match up to the prices to the number of pairs of jeans. then just look at ur table for jeans and see which one has the greatest value. by equivalent it means are they the same as the one that is greatesst on table D and see if any of them are equivalent to the one you chose for E. for F all you would have to do is divide the number in A by 7. then just look at ur previous tables and find ur ratio
Tim will pay the same amount whether buying locally or online, without considering sales tax. The price per jeans remains constant in both local and online stores. When sales tax is applied, the ratio of number of pairs to price changes, increasing the cost per pair.
Each part of the problem step by step:
Part A:
Tim wants to buy three pairs of jeans. He can either purchase them at a local store for $24 each or online for $22 each plus a $6 shipping fee per order.
Part B:
For the local store, the ratio of the number of pairs of jeans (3) to the cost per pair ($24) is 3/24 = 1/8.
Part C:
The ratios calculated in Part B are not equivalent. As the number of pairs of jeans increases at the local store, the cost decreases proportionally.
Part D:
For the online store, the ratio of the number of pairs of jeans (3) to the cost per pair ($22) plus the shipping fee ($6) is 3/(22+6) = 3/28.
Part E:
The ratios calculated in Part D are not equivalent either. As the number of pairs of jeans increases online, the cost per pair decreases due to the shipping fee.
Part F:
To find the cost of jeans at the local store with a 7% sales tax, multiply the cost by 1.07 (since it's an increase of 7%). The table can be filled accordingly.
Part G:
Now, calculate the ratio of the number of pairs of jeans (3) to the cost with sales tax for each row in the table.
Part H:
The ratios calculated in Part G are not equivalent. The relationship between the number of pairs of jeans and the cost with sales tax applied at the local store shows that as the number of pairs increases, the cost with tax also increases proportionally.

Determine the numbers of zeros of the polynomial function
g(x) = x^4-x^5
___ zero(s)
Answers
Factor out x^4 for find zeros:
g(x) = x^4 (1-x)
From this, we can see that if x = 0 or 1, it would cause g to result in 0.
So the zeros are 0 and 1.
The polynomial function g(x) = [tex]x^4 - x^5[/tex] has two zeroes, which are x = 0 and x = 1. This result is obtained by setting the polynomial equal to zero and solving for x.
Explanation:The given polynomial function is g(x) = [tex]x^4 - x^5[/tex]. To find the zeroes of the polynomial, this function should equal zero. Thus, we have[tex]x^4 - x^5[/tex] = 0.
We can simplify this function by factoring out the common factor, which is [tex]x^4[/tex]. The function thus becomes [tex]x^4[/tex](1 - x) = 0.
A product equals zero when one (or more) of the factors is zero. So, we need to set each factor to zero and solve for x. Setting [tex]x^4[/tex]= 0, yields x = 0. Setting (1 - x) = 0 results in x = 1.
This process gives two values of x that satisfy the equation [tex]x^4[/tex](1 - x) = 0 and therefore, the polynomial function g(x) has two zeroes, specifically x = 0 and x = 1.

2 mugs.
Step-by-step explanation:
We have been given that Ron made [tex]\frac{2}{3}[/tex] of a quart of hot chocolate. Each mug holds [tex]\frac{1}{3}[/tex] of a quart.
To find the number of mugs that can be filled by [tex]\frac{2}{3}[/tex] quart of hot chocolate, we will divide [tex]\frac{2}{3}[/tex] by [tex]\frac{1}{3}[/tex] as:
[tex]\frac{2}{3}\div\frac{1}{3}[/tex]
Now, we will convert the division problem to multiplication problem by flipping the 2nd fraction as:
[tex]\frac{2}{3}\times\frac{3}{1}[/tex]
[tex]\frac{2\times 3}{3\times 1}[/tex]

domain represents the x-values. the x-values start at 1 and end at 9. 1 is included and 9 is included (otherwise an open dot would be shown).
1 ≤ x ≤ 9
because as you can see on the graph the line starts at X cordinate 1 and ends at 9. so we can say 1<x<9. then we are going to have to add an equall sign because the line includes 1 and 9. so it will be like this---1 ≤ x ≤ 9.
There are 15 cats ready for new homes at the pet store. There are 5 cages with cats in the store. If each cage has the same number of cats, how many cats are in each cage?
Answers
There are 3 cats in each cage. They way you get this answer is by dividing the total amount of cats (15) by the total amount of cages (5). hope this helps
We find that there are 3 cats in each cage.
To find out how many cats are in each cage, we need to divide the total number of cats by the number of cages. There are 15 cats ready for new homes and 5 cages. If each cage has the same number of cats, we perform the following calculation:
Count the total number of cats: 15 cats.
Count the total number of cages: 5 cages.
Divide the total number of cats by the number of cages: 15 cats / 5 cages = 3 cats per cage.
Therefore, there are 3 cats in each cage.
