The linear function that represents the profit earned is: C. y = 2x − 48.
How to Write a Linear Function?The linear Function can be written as y = mx + b, which is in slope-intercept form, where we have:
x and y as the variables.m as the slope/unit rate.b as the starting value or y-intercept of the linear function.From the information given, we have:
x = number of hot dogs sold
y = Profit earned
m = unit rate = 2
b = starting value = -48 (this is negative because the profit on each hot dog sold must be deducted from the cost for each morning.)
Therefore, substitute m = 2 and b = -48 into y = mx + b to write the linear function:
y = 2x - 48

39 pounds of type coffee were used.
Type a coffee costs, Kira, $5.85 per pound, and type b coffee cost $4.20 per pound.
let, A pound of type a coffee,
B pounds of type b coffee.
according to the question;
this month's blend used 3 times as many pounds of type B coffee as type A coffee.
Total pounds of coffee = x + 3x
The total cost then is:
(cost for Type A)(x) + (cost for Type B)(3x) = 717.60

The sentence for 4x-9 = 19 is "when 9 is subtracted from 4 times a number, it equals 19."
What in mathematics is a conditional sentence?Definition. A conditional statement is one that has the syntax "If P then Q," with P and Q denoting sentences. P is referred to as the hypothesis and Q is referred to as the conclusion for this conditional statement. The implication of "If P then Q" is that whenever P is true, Q must also be true.
We have a conditional statement, for instance. In the event of rain, we will not play. Let's say A: It's raining and B: We're not going to play. If A is true—that is, if it is raining—and B is false—that is, if we played—then A implies that B is untrue.

A cucumber seed needs to be planted 1 inch deep for optimal growth. the plant grows an average of 3 inches every 2 weeks. then the slope in the situation is 2
How do you find the slope of a line?
We need to find the ratio of the difference between the y-coordinates and x-coordinates of the two points, that form the line. The resulted value is the slope of the line. It shows the rise of the line along the y-axis over the run along x-axis.
since seed planted 1 inch deep then y1 = -1 and initial x1 =0
the plant grow an average of 3 inches every 2 weeks then y2 =3 and x2=2
putting in the formula
slope= y2 -y1 /x2 -x1
= 3-(-1)/2-0
= 4/2
=2

For each value of v, determine wether it is a solution to 1-7v=-69.
For v = -4, 0, and 8 are not solutions of the equation 1 - 7v = - 69. The solution of the equation is v = 10.
Consider the equation,
1 - 7v = - 69
For the value of v = - 4,
1 - 7v = - 69
1 - 7 × - 4 = - 69
1 + 28 ≠ - 69
29 ≠ - 69
Hence, v = - 4 is not a solution.
For v = 10,
1 - 7v = - 69
1 - 7 × 10 = - 69
1 - 70 = - 69
- 69 = - 69
Therefore, v = 10 is a solution.
For the value of v = 0,
1 - 7v = - 69
1 - 7 × 0 = - 69
1 ≠ - 69
Hence, v = 0 is not a solution.
For the value of v = 8,
1 - 7v = - 69
1 - 7 × 8 = - 69
1 - 64 ≠ - 69
- 63 ≠ - 69
Hence, v = 8 is not a solution.

Timmy has stamps. He wants to organize them on pages that hold stamps each. He has pages. Does Timmy have enough pages to organize all his stamps?
Using division we can infer that 50 pages will not be enough.
Division is one of the four basic arithmetic operations, or the process by which two numbers are added together to produce a new number.
Multiplication, subtraction , and addition make up the remaining operations. The division with remainder, also known as Euclidean division, of two natural numbers produces an integer quotient, which is the number of times the second number is entirely contained in the first number, and a remainder, which is the portion of the first number that is left over, when it is impossible to allocate any more full chunks of the size of the second number during the computation of the quotient after the division.Timmy has 810 stamps.
Now each page can hold 16 stamps and he has 50 pages.
Now we will divide 810 by 16 to calculate the number of pages required to put all the stamps.
∴ 810 ÷ 16 = 50 remainder 10.
Therefore after completing the 50 pages there are 10 stamps left.
Hence from division we can infer that 50 pages will not be enough.

You want to fence off a rectangular area of yard using the back side of your house as one of the sides. You have a total of 150 yards of fence. If the area of the fenced in portion comes to 2,800 square yards, what are the dimensions of the fenced-in area? Show all work for full credit.
The dimensions of the fenced-in area is given as
either length is 35 yards and width is 80 yards ,
or length is 40 yards and width is 70 yards .
In the question ,
given that the total length of the fence (perimeter) = 150 yards
let L be the length of the portion to be fenced
let B be the width of the house
Given that , one side of the portion is fenced using the back side of the house
So, the perimeter of the portion to be fenced is 2L+B
equating both the perimeter ,we get
2L+B=150
B=150-2L ....(i)
Also , given that the area of the fenced-in portion = 2800 yards
also the formula for area of fenced-in portion = L×B
hence
L*B=2800
Substituting the values of B from equation(i) , we get
L*(150-2L)=2800
150L - 2L² = 2800
2L² - 150L + 2800 = 0
simplifying further , we get
L² - 75L + 1400 = 0
L² -40L -35L +1400 = 0 .....using splitting the middle term
L(L-40) -35(L-40) = 0
(L-35)(L-40) = 0
So , L = 35 yards or L = 40 yards
Using L = 35 yards , we get B = 150-2(35) = 80 yards
and using L =40 yards , we get B = 150-2(40) = 70 yards .
Therefore , the dimensions of the fenced-in area is given as
either length is 35 yards and width is 80 yards ,
or length is 40 yards and width is 70 yards .

Step-by-step explanation:
Area of rectangle = length x width
The length of the rectangle is 12 feet, and the width is (2x - 3) feet.
Area = 12 x (2x - 3)
= 12(2x - 3)
From the given question,
area of rectangle > 60 square feet
So that;
12(2x - 3) > 60
24x - 36 > 60
24x > 60 + 36
24x > 96
Divide both sides by 24, to have;
=
x > 4
Therefore,
width = (2x -3)
since x > 4, then;
width > (2x4 - 3)
> 8 -3
width > 5 feet
Thus,
length x width > 60
Lincoln went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium. Lincoln purchased a total of 13 cans of soup and frozen dinners which collectively contain 4450 mg of sodium. Determine the number of cans of soup purchased and the number of frozen dinners purchased.
There are 9 cans of soup and the 4 frozen dinners that were purchased.
How to explain the information?Let x = the number of cans of soup purchased.
Let y = the number of frozen dinners purchased.
Lincoln purchased a total of 13 cans of soup and frozen dinners. This means that
x + y = 13 ..... i
x = 13 - y
The equation will be illustrated as
250x + 550y = 4450 .... ii
Substituting x = 13 - y into equation ii, it becomes
250(13 - y) + 550y = 4450
3250 - 250y + 550y = 4450
- 250y + 550y = 4450 - 3250
300y = 1200
y = 1200/300
y = 4

What is compound interest?Compound interest is when you receive the interest on both your interest income and your savings.
For instance, if you deposit $1,000 in an account that offers 1% yearly interest, after a year you would have received $10 in interest. Compound interest allowed you to earn 1 percent on $1,010 in Year Two, which amounted to $10.10 in interest payments for the year.
The yearly interest rate is raised to number of compound periods minus one, and the starting principal amount is multiplied by both of these factors. The resulting value is subsequently deducted from loan's entire original amount.
