Which equation matches the graph of the greatest integer function given
below?
A. y = [x]-2
B. y = [x] +2
C. y -[x]+3
D. y = [x]-3
The equation that matches the graph of the greatest integer function is y = [x] - 2
How to determine the equation?The parent function of an step function is represented as:
y = [x]
From the given graph, we can see that the lines are shifted 2 units down.
This means that:
(x,y) = (x,y - 2)
So, we have:
y = [x] - 2
Hence, the equation that matches the graph of the greatest integer function is y = [x] - 2

Given: ΔABC (to the right)
AB=15
BD=9
AD⊥BC
m∠C=30°
Find Perimeter of ABC
Applying the Pythagorean theorem and the trigonometric ratios, the perimeter of triangle ABC is: 68.8 units.
What is the Perimeter of a Triangle?The perimeter of a triangle = sum of its 3 sides.
Given the following:
AB = 15 BD = 9m∠C=30°Use the Pythagorean theorem to find AD considering triangle ADB as a right triangle:
AD = √(15² - 9²)
AD = 12 units
Use the trigonometric ratios to find DC and AC:
sin 30 = AD/AC
sin 30 = 12/AC
AC = 12/sin 30
AC = 24 units
tan 30 = AD/DC
tan 30 = 12/DC
DC = 12/tan 30
DC ≈ 20.8 units
BC = BD + DC = 9 + 20.8
BC = 29.8 units.
Perimeter of triangle ABC = BC + AB + AC
Perimeter of triangle ABC = 29.8 + 15 + 24
Perimeter of triangle ABC = 68.8 units.

Which equation is equivalent to the given equation?
- 4(x - 5) + 8x = 9x - 3
A.
-5x = -23
B.
5x = 17
C.
-5x = 2
D.
5x = -12
Answer:
A. -5x = -23
Step-by-step explanation:
First you have to simplify the equation - 4(x - 5) + 8x = 9x - 3
-4x + 20 + 8x = 9x -3
9x - 4x = 20 + 3
5x = 23
=> equivalent to answer A.
The equivalent expression is,
⇒ - 5x = - 23
We have to given that,
An expression is,
- 4 (x - 5) + 8x = 9x - 3
Now, We can simplify the expression for equivalent expression,
- 4 (x - 5) + 8x = 9x - 3
Apply distributive property, we get;
- 4x + 20 + 8x = 9x - 3
4x + 20 = 9x - 3
4x - 9x = - 20 - 3
- 5x = - 23
Therefore, The equivalent expression is,
⇒ - 5x = - 23

Two boxes of apples weigh 35 lb. If one of the boxes weighs 12 lb, then find the weight of the second box.
The larger of two numbers is 15 more than the smaller number. If the sum of the two numbers is 27, find the two numbers.
Larger Number:
Smaller Number:
Answer:
Larger number: 21
Smaller number: 6
Step-by-step explanation:
Step 1: Make equations.
x ... larger number
y ... smaller number
First equation: The larger of two numbers is 15 more than the smaller number.
x = y + 15
Second equation: Sum of the two numbers is 27.
x + y = 27
Step 2: Solve the system of equations.
First equation: x = y + 15
Second equation: x + y = 27
Substitute x in second equation with x from first.
x + y = 27
(y + 15) + y = 27
Solve for y.
y + 15 + y = 27
2y = 27 - 15
2y = 12
y = 6
Substitute the calculated value of y back in first equation to get x.
x = y + 15
x = 6 + 15
x = 21

*WILL GIVE BRAINLIEST* The table below contains partial data points of Red Bird's trajectory.
Horizontal distance traveled is 12unit, Equation in standard form is y = -4x² + 120x - 680 and Equation in vertex form is y = -4(x - 15)² + 220
Horizontal Distance Traveled
To find the horizontal distance traveled by Red Bird, we need to calculate the difference between the largest and smallest values of the X-axis data points. In this case, the horizontal distance traveled is:
Horizontal Distance Traveled = Largest X value - Smallest X value
= 17 - 5
= 12 units
The horizontal distance traveled by Red Bird is 12 units.
Equation in Standard Form
To find the equation in standard form, we need to determine the equation of a quadratic function that fits the given data points. Since we have more than three data points, we can use a quadratic regression to find the equation.
Using a regression tool or mathematical software, the equation in standard form for the given data points is:
y = -4x² + 120x - 680
Equation in Vertex Form
To find the equation in vertex form, we can convert the equation from standard form to vertex form by completing the square. The vertex form of a quadratic equation is given by:
y = a(x - h)² + k
To convert the equation to vertex form, we need to rewrite it by completing the square. The steps are as follows:
y = -4x² + 120x - 680
First, factor out the common coefficient -4:
y = -4(x² - 30x + 170)
To complete the square, we need to add and subtract the square of half the coefficient of x, which is (30/2)² = 225:
y = -4(x² - 30x + 225 - 225 + 170)
Now, rewrite the equation by grouping:
y = -4((x - 15)² - 55)
y = -4(x - 15)² + 220
The equation in vertex form is:
y = -4(x - 15)² + 220
So, the equation in vertex form for the given data points is y = -4(x - 15)² + 220.

Which polynomial is prime?
O x²+x+1
O x²-x-2
O x²-12x + 11
Ox²+2x-8
Answer:
The correct answer is x^2 + x + 1.
Step-by-step explanation:
A prime polynomial is one that cannot be factored. To solve this problem, we can use the process of elimination by eliminating all answer choices that can be factored.
x^2 - x - 2 = (x - 2)*(x + 1)
x^2 - 12x + 11 = (x - 11)*(x - 1)
x^2 + 2x - 8 = (x + 4)*(x - 2)
Since we cannot factor x^2 + x + 1, and we can factor all of the other answer choices, we know that x^2 + x + 1 is the answer.

In a graph, x represents the number of months since a business opened, and y represents the total amount of money the business has earned. The following three points are from the graph:
(2, 1990) (5, 4225) (9, 7205)
Find the slope and y-intercept. Explain what each represents.
The slope of the graph is 745 and the y-intercept of the graph is 500
How to determine the slope?The points are given as:
(2, 1990) (5, 4225) (9, 7205)
The slope is calculated using:
m = (y2 - y1)/(x2 - x1)
So, we have:
m = (4225 - 1990)/(5 - 2)
Evaluate
m = 745
This means that the amount earned per day is 745
Hence, the slope of the graph is 745
How to determine the y-intercept?In (a), we have
m = 745
To calculate the y-intercept, we use the following points
(x1 , y1) = (0,y)
Recall that:
m = (y2 - y1)/(x2 - x1)
So, we have:
745 = (4225 - y)/(5 - 0)
Evaluate the difference
745 = (4225 - y)/(5)
Multiply both sides by 5
3725 = 4225 - y
Solve for y
y = 500
This means that the initial amount earned is 745
Hence, the y-intercept of the graph is 500
