Answer:

The school ordered more than enough concrete to completely fill in the court, so the number of bags of concrete ordered, represented by x, must be greater than the number of cubic yards of concrete needed to fill the court. This can be represented by the inequality x > 60 cubic yards / 0.5 cubic yards/bag. Solving for x, we get x > 60 * 2 = 120. Therefore, the inequality that describes the problem is x > 120.

The taxi can travel a maximum distance of 11 miles if we have at most $10 to spend on the cab ride.

What is distance?

The length of the line connecting two places represents the distance between them. Subtracting the different coordinates will reveal the distance if the two points are on the same horizontal or vertical line.

The formula for measuring distance between two lines, the total length of all a polygon's sides, the perimeter of a polygon on a coordinate plane, the area of a polygon, and many other things are all found in analytical geometry. For instance, we can use the distance formula to find the lengths of a triangle's sides and decide if it is scalene, isosceles, or equilateral.

It is given that, a taxi charges a flat rate of $1.75 plus an additional fee of $0.75 per mile.

We have to find the maximum distance it could travel at most with $10

Let the maximum distance be x miles.

Thus, the fare would be

$(1.75 + 0.75x) = 10

⇒ 0.75x = 8.25

⇒ x = 8.25/0.75

⇒ x = 11

The taxi can travel a maximum distance of 11 miles if we have at most $10 to spend on the cab ride.

If the two bikes are racing a distance of 100 feet, the bike that will win the race is: D. Bike 1 will win because the slope of the line for Bike 1 is 3/2, which is greater than the slope of the line for Bike 2.

Mathematically, the slope of any straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Next, we would calculate the slope of the line representing the distance covered by each of the bikes based on the data points on their graph.

For Bike 1, the slope is given by;

Slope, m = (6 - 3)/(4 - 2)

Slope, m = 3/2

Slope, m = 1.5.

For Bike 2, the slope is given by;

Slope, m = (10 - 5)/(8 - 4)

Slope, m = 5/4

Slope, m = 1.25.

Therefore, the slope of Bike 1 is greater than the slope of Bike 2.

The cost of admission to the library for each student will be $0.3125. And the admission cost of the zoo will be $156.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Mrs. Hudson's class of 18 understudies is going to the zoo. Every understudy will pay for confirmation and purchase lunch. Mr. Weaver's class of 24 understudies is going to the library. Every understudy will pay for affirmation and pay for transport passage.

Let 'x' be the cost of admission to the library for each student. Then the equation is given as,

$7.50 + $8.25 × 18 + $5.75 × 18 = 24x + $10.50 × 24

Simplify the equation, then we have

$7.50 + $8.25 × 18 + $5.75 × 18 = 24x + $10.50 × 24

$7.50 + $148.5 + $103.5 = 24x + $252

$259.5 - $252 = 24x

Landon is a high school basketball player. In a particular game, he made some two point shots and some three point shots. Landon scored a total of 24 points and made 2 more two point shots than three point shots. Graphically solve a system of equations in order to determine the number of two point shots made, x, and the number of three point shots made, y.

x = the number of two point shots made

y = the number of three point shots made

Each two point shot scores 2 points, so x two point shots would score 2x points. Each three point shot scores 3 points, so y three point shots would score 3y points.

Therefore, the total number of points scored 2x + 3y equals 24 :
2x+3y=24

Since Landon made 2 more two point shots than three point shots, if we add 2 to the number of three point shots made, we will get the number of two point shots made, meaning x equals y + 2.

                                                                                    x = y + 2

Write System of Equations:

​2x + 3y = 24

         x = y + 2

Solve for y in each equation:

The function's standard form equation is equivalent to

y=(1/2)x²+(-7x)+24.

A mathematical expression (equation) that can be used to define and represent the relationship between two or more variables on a graph is known as a quadratic function.

The standard form of a quadratic equation in mathematics is represented by;

ax² + bx + c = 0

y=ax² + bx + c

The information in the table above would then be used to create a set of equations:

The points are (4, 4), (6, 0), (8, 0), (10, 4)

4=a(4)²+b(4)+c

16a+4b+c=4 ------(1)

0=a(6)²+b(6)+c

36a+64b+c=0  ------(2)

0=a(8)²+b(8)+c

64a+8b+c=0  -------(3)

By solving 2 and 3 equations, we get

Eq2-Eq3,

We get b= -14a

By substituting b value in eq2 we get,

36a+6b+c=0

36a+6(-14a)+c=0

35a-84a+c=0

c=48a

By substituting a, b values in eq1 we get,

16a+4(-14a)+48a=4

16a-56a+48a=4

-40a+48a=4

8a=4

a=1/2

Then, b=-14a

b= -7

c=48a

c=24

Now, by substituting these a, b, c values in,

y=ax² + bx + c

y=(1/2)x²+(-7x)+24

By  checking the above equation is correct or not,

We consider the fourth value x=10

When x=10,

y=(100/2)-70+24

y=50-70+24

y=4

From the given table if x=10 then y=4,

So it satisfies with the equation we get.

Therefore, the function's standard form equation is equivalent to

y=(1/2)x²+(-7x)+24.

An equivalent equation is one that yields the same solution as the original equation.

The equivalent equation is obtained by removing a variable from the given equation. There will be the same number of equivalent equations as there are variables in an equation.

Given that,

m = ca

Here m, c, and a are the three variables in the given equation.

We can write the equation into two more forms as follows:

m = ca

Dividing both sides by 'a'

⇒ ca/a = m/a

c = m/a

The speed of the ball after one second is given as follows:

9.175 m/s.

The speed function is the derivative of the position function, which is graphed in this problem.

The position function, in meters, for a projectile's height, is given as follows:

h(t) = -4.9t² + v(0)t + h(0).

In which:

From the graph, the initial height is given as follows:

h(0) = 6.

When t = 4, h = 2.5, hence the initial velocity is obtained as follows:

2.5 = -4.9(4)² + 4v(0) + 6

4v(0) = 2.5 - 5 + 4.9(4)²

4v(0) = 75.9

v(0) = 75.9/4

v(0) = 18.975.

Then the position function is of:

h(t) = -4.9t² + 18.975t + 6.

The velocity function is the derivative of the position, hence:

v(t) = -9.8t + 18.975.

Then the velocity after one second is of:

v(1) = -9.8 + 18.975 = 9.175 m/s.

Answer:

Since the slope is undefined, this is a vertical line. Vertical lines have no y-intercept. No y-intercept.

Step-by-step explanation:

hope this helped:)

Answer:

To write the equation of a line in slope-intercept form, we need to first find the slope of the line. The slope is a measure of the steepness of the line, and is calculated as the rise over the run between two points on the line. In this case, we can use the points (-6,-3) and (6,-7) to calculate the slope.

To find the slope, we first need to find the difference between the y-coordinates of the two points, which is -3 - (-7) = 4. We then need to find the difference between the x-coordinates of the two points, which is 6 - (-6) = 12. The slope is then calculated as the rise over the run, which is 4/12 = 1/3.

Once we have the slope, we can use the point-slope formula to write the equation of the line in slope-intercept form. The point-slope formula is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. In this case, we can use the point (-6,-3) and the slope 1/3 to write the equation of the line.

The equation of the line in slope-intercept form is then y - (-3) = 1/3(x - (-6)), which simplifies to y + 3 = 1/3x + 2. This is the equation of the line that passes through the points (-6,-3) and (6,-7) in slope-intercept form.

Therefore, the correct answer is y + 3 = 1/3x + 2.
