The ordered pair that represents a function is:
⇒ (-3, -3), (-2, 2), (1, 1), (2, -2)
What is Coordinates?
A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
The given points are;
(-3, -3), (-2, 2), (1, 1), (2, -2)
(-3, 3), (-3, -3), (-1, 1), (1, 4)
(-4, 4), (-4, 1), (-2, 1), (2, 1)
(-3, 3), (-3, -3), (1, -4), (1, 1)
Now, For an ordered pair to be a function, either of the following must be true:
Each x-value have exactly one corresponding y-value.
More than one x-values have the same corresponding y-values.
And, If any of the following conditions is true, then the ordered pair is not a function,
One x-value have multiple corresponding y-values.
More than one x-values have the multiple corresponding y-values.
From the given options, only ordered pair (-3, -3), (-2, 2), (1, 1), (2, -2) satisfies the condition to be a function.
Because none of its x-values have multiple corresponding y-values.
And, Other ordered pairs are either one-to-many or many-to-many.
So, The ordered pair that represents a function is:
⇒ (-3, -3), (-2, 2), (1, 1), (2, -2)

Question content area top Part 1 The calorie count of a serving of food can be computed based on its composition of carbohydrate, fat, and protein. The calorie count C for a serving of food can be computed using the formula X=5h+8 f+5p, where he is the number of grams of carbohydrate contained in the serving, f is the number of grams of fat contained in the serving, and p is the number of grams of protein contained in the serving. Solve this formula for f, the number of grams of fat contained in a serving of food
Using the calorie count C for a serving of food C =5h + 8f + 5p, the formula for f is derived to be; f = (C - 5h - 5p) / 8
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
WE have been Given data that C =5h + 8f + 5p
Where C is the calorie count, h is the number of grams of carbohydrate, f is the number of grams of fat and p is the number of grams of protein
Now solving for f in the given equation;
C = 5h + 8f + 5p
Then f the subject of formula;
C - 5h - 5p = + 8f
8f = C - 5h - 5p
Now dividing through by 8
f = (C - 5h - 5p) / 8
Hence, The number of grams of fat, f, contained in a serving of food is; f = (C - 5h - 5p) / 8

If Joe deposits every payment in an account paying a nominal annual interest rate of 6% compounded monthly, how much will he have at the end of three years?
If you want $1,000 five years from now and you earn 5 percent on your savings, how much do you need to deposit today?
The distinction between present value and future value is that the former is required now and the latter is needed at a future period
What is the difference between present value and future value?
The present value indicates today's worth or dollars of a future value of a flow whereas the future value determines the future worth of an investment or deposit made today or deposits over a number of years at a time in the future
The amount that Claudia would have in a year's time is future value because the present value is the initial deposit made today
The amount that Steven would have to deposit today in order to accumulate $400,000 in 15 years is the present value
The amount that a deposit of $4,500 made today would worth in 6 years is the future value because the initial deposit is the present value.

In accordance with algebra fundamental theorem, we can construct a quadratic equation by knowing the locations of at least three points on Cartesian plane. Herein we find a quadratic equation in vertex form, whose formula is described below:
y - k = C · (x - h)²
Where:
h, k - Coordinates of the vertex.C - Vertex constant.By using this expression, we can find the locations of the vertex and intercepts of the parabola. Now we proceed to find all the required information:
Vertex
y = (x + 5)²
(h, k) = (- 5, 0)
x-Intercepts
(x + 5)² = 0
x = - 5
y-Intercept
y = (0 + 5)²
y = 25
Another point
x = - 1
y = (- 1 + 5)²

a. F(x)=6/x-2
b. r(x)=6x+12/x²-4
These are our two tables of values for the following functions using the integers from -4 to 4.
What is function?A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given:
The given functions using the integers from -4 to 4 are
a. F(x)=6/x-2b.
r(x)=6x+12/x²-4
According to given question we have
f(x) = 6/x - 2
Now we just need to evaluate the function in all the given points:
a) f(x) = 6/x - 2
Now we can put the value
f(-4) = 6/(-4) - 2 = -3/2 - 4/2 = -7/2
f(-3) = 6/-3 - 2 = -4
f(-2) = 6/-2 - 2 = -5
f(-1) = 6/-1 - 2 = -8
f(0) is undefined
f(1) = 6/1 - 2 = 4
f(2) = 6/2 - 2 = 1
f(3) = 6/3 - 2 = 0
f(4) = 6/4 - 2 = -1/2
b. r(x)=6x+12/x²-4
Now we can put the value
r(-4) = 6(-4)+12/(-4)²-4=-27.25
r(-3) = 6(-3)+12/(-3)²-4=-20.66
r(-2) = 6(-2)+12/(-2)²-4=-13
r(-1) = 6(-1)+12/(-1)²-4= 2
r(0) = 6(0)+12/(0)²-4= ∞
r(1) = 6(1)+12/(1)²-4 =14
r(2) = 6(2)+12/(2)²-4=11
r(3) = 6(3)+12/(3)²-4 =15.33
r(4) = 6(4)+12/(4)²-4=20.75

At the neighborhood grocery, 3.5 pounds of steak cost $36.75. Hannah spent $8.61on steak. How many pounds of steak did she buy, to the nearest hundredth of a pound?
The number of pounds of steak she buys is 0.82 pounds
How to determine the number of pounds of steak she buys?From the question, we have the following parameters:
3.5 pounds of steak = $36.75
From the question, we understand that
Hannah spent $8.61 on steak
This means that
x pounds = $8.61
So, we have the following system of equations
3.5 pounds of steak = $36.75
x pounds = $8.61
Cross multiply in the above equation
So, we have
36.75 * x = 3.5 * 8.61
Divide both sides of the equation by 36.75
x = 3.5 * 8.61/36.75
Evaluate the quotient
x = 0.82
Hence, the number of pounds of steak she buys is 0.82 pounds

(-1, 8) and (5,-2) equation must be in slope intercept form
The linear equation that passes through (-1, 8) and (5,-2) is:
y = (5/3)*x + 29/3
How to find the linear equation?
A general linear equation in the slope-intercept form is:
y = a*x + b
Where a is the slope, and b is the y-intercept.
If we know that this line passes trhough the points (-1, 8) and (5, -2) then we can write the slope as:
a = (-2 - 8)/(5 + 1) = -10/6 = 5/3
Then we can write:
y = (5/3)*x + b
Now to find the value of b we can replace the values of one of the points in the line, if we use (-1, 8) we will get:
8 = (5/3)*-1 + b
8 + 5/3 = b
24/3+ 5/3 = b
29/3 = b
We conclude that the linear equation is:
y = (5/3)*x + 29/3
