payton wants to buy kiwi and cherries to make a fruit tart. Kiwi cost $2.25 per pound and cherries cost $4.25 per pound. How many pounds of fruit does she buy if she buys 3 pounds of kiwi and 1.5 pounds of cherries? How many pounds of fruit does she buy if she buys xx pounds of kiwi and yy pounds of cherries?
If Payton buys 3 pounds of Kiwi and 1.5 pounds of cherries, then the pounds of fruit Payton bought at 4.5 pounds.
If Payton buys x pounds of Kiwi and y pounds of cherries, the number of pounds of fruit purchased is x + y.
How much fruit did Payton buy?Payton bought 3 pounds of kiwi and 1.5 pounds of cherries. The total fruits bought is therefore:
= 3 + 1.5
= 4.5 pounds of fruit
If Payton bought x pounds of kiwi and y pounds of cherries, again the total pounds purchased is:

What is the End behavior of the Polynomial?
The Factor Theorem states that a function with leading coefficient a and zeros x1, x2, x3,....,xn is defined by;
g(x) = a(x - x1)(x - x2).....(x - xn)
In the given table;
f(x) = 0 for x = -4 and 12. Thus, the zeros are x1 = -4 and x2 = 12
Then the definition is;
g(x) = a(x + 4)(x - 12)
g(x) = a(x² - 8x - 48)
The end behavior is the limit of g(x) as x goes to infinity, thus:
limₓ→ ∞ g(x) = limₓ→ ∞ax² = a * ∞
Since the leading coefficient a is negative, then;
a * ∞ = - ∞
Thus, the end behavior of g(x) is; As x→–∞, g(x)→–∞ and as x→∞, g(x)→–∞.

The complete question is given below:
When bonding teeth, orthodontists must maintain a dry field. A new bonding adhesive (called "Smartbond") has been developed to eliminate the necessity of a dry field. However, there is concern that the new bonding adhesive is not as strong as the current standard, a composite adhesive. ( Trends in Biomaterials & Artificial Organs, Jan. 2003.) Tests on a sample of 10 extracted teeth bonded with the new adhesive resulted in a mean breaking strength (after 24 hours) of x = 5.07 Mpa and a standard deviation of s = 0.46 Mpa, where Mpa = megapascal, a measure of force per unit area. Orthodontists want to know if the true mean breaking strength of the new bonding adhesive is less than 5.70 Mpa, the mean breaking strength of the composite adhesive. Conduct the appropriate analysis for the orthodontists. Use alpha= 0.01. What is the p-value?

Straight Line:
A straight line is just a line with no curves. So, a line that extends to both sides till infinity and has no curves is called a straight line.
Slope:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Use the slope and one of the points to solve for the y-intercept (b).
One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.
Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line

The complete arithmetic sequence is 1, .25, -0.5, -1.25, -2
How to complete the arithmetic sequence?The arithmetic sequence is given as:
1, .25, blank, -1.25, blank
Replace the blanks in the arithmetic sequence with x and y
So, we have:
1, .25, x, -1.25, y
An arithmetic sequence has a common difference (d)
The common difference is calculated using
d = T2 - T1
So, we have
d = 0.25 - 1
d = x - 0.25
d = y + 1.25
Substitute d = x - 0.25 in d = 0.25 - 1
x - 0.25 = 0.25 - 1
This gives
x = 0.25 + 0.25 - 1
Evaluate the sum
x = -0.5
Substitute d = 0.25 - 1 in d = y + 1.25
0.25 - 1 = y + 1.25
This gives
y = 0.25 - 1 - 1.25
Evaluate
y = -2

MODELING REAL LIFE You consider buying a phone from one of two cell phone carriers. The table shows the total costs
(in dollars) of the phone and service for different numbers of months at Carrier A. The total cost y (in dollars) of the phone
and x months of service at Carrier B is represented by the equation y = 55x + 300. Which carrier has the lower initial fee?
Answer:
Step-by-step explanation:
The carrier that has the lower initial fee is carrier B
How to determine which carrier has the lower initial fee?For carrier B, we have the following equation
y = 55x + 300
Set x = 0 to determine the initial fee
y = 55 x 0 + 300
Evaluate
y = 300 ---- the initial fee of carrier B
For carrier A, we have the following points on the table
(x, y) = (3, 500), (6, 650)
The slope of the points is calculated using
m = (y2 - y1)/(x2 - x1)
This gives
m = (650 - 500)/(6 - 3)
Evaluate
m = 50
Let the initial fee of carrier B y
So, we have the following points
(x, y) = (0, y), (6, 650)
The slope of the points is calculated using
m = (y2 - y1)/(x2 - x1)
This gives
m = (650 - y)/(6 - 0)
Evaluate
m = (650 - y)/6
Substitute m = 50 in m = (650 - y)/6
50 = (650 - y)/6
This gives
300 = 650 - y
Solve for y
y = 350
So, we have:
y = 300 ---- the initial fee of carrier B
y = 350 ---- the initial fee of carrier A
300 is less than 350
Hence, the carrier that has the lower initial fee is carrier B
