The coordinate of a point is its location on a grid. The point will be located halfway between -2 and -3 on the x-axis, on -4 on the y-axis
Coordinate points:
A set of values that show an exact position on graphs is usually a pair of numbers. The first number shows the distance along, and the second number shows the distance up or down.
One number line is horizontal and is called the x-axis, and the other number line is the vertical number line and is called the y-axis. The two axes meet at a point called the origin.
The coordinate is given as:
[tex]Point=(2\frac{1}{2} ,-4)[/tex]
Express as decimals
Point=(-2.5,-4)
The above point means that:

96 tulips to make the bouquets. On Tuesday, she used 192 tulips to make the same number of Spring Mix
bouquets as Monday, but 3 times as many Garden Delight bouquets.
a. Write a system of equations that you can use to find how many bouquets of each type Marisol made.
b. Find the total number of tulips Marisol used to make Garden Delight bouquets on Monday and Tuesday.
To calculate how many flowers of each kind Marisol created, use the formulae x+y=96 and x+3y=192. Marisol used 48 tulips in total to produce Garden Delight bouquets on Monday and Tuesday.
What is equation?In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.
Here,
Let x be Spring Mix bouquets and y be the Garden Delight bouquets.
x+y=96
x+3y=192
2y=96
y=48
x=48
The system of equations that you can use to find how many bouquets of each type Marisol made is x+y=96 and x+3y=192. The total number of tulips Marisol used to make Garden Delight bouquets on Monday and Tuesday is 48.

A ball is launched from a 25.48-meter tall platform. The equation
for the ball's height h at time t seconds after launch is h (t) =
-4.9t2 +20.58t + 25.48, where his in meters. What is the
maximum height the ball achieves before landing?
Answer:
[tex]\boxed{47.089 \;meters} \\\\[/tex]
Step-by-step explanation:
For any function f(x), the maximum or minimum value can be determined by 1. Finding the first derivative f(x) with respect to x i.e. f'(x)
2. Setting this first derivative to 0, solving for x
3. Substituting for x in the original function to get the maximum/minimum value
[tex]\textrm{The equation for the function f(t) is }\\f(t) = -4.9t^2 + 20.58t + 25.48\\\\[/tex]
[tex]\textrm{The first derivative of this function with respect to t is }\\\\f'(t) = - 2\cdot 49t + 20.58\\= -9.8t + 25.48\\\\[/tex]
[tex]\textrm{Setting this first derivative equal to 0 gives:}\\\\-9.8t + 20.58 = 0\\\\-9.8t = -20.58 \;\;\;\;\;\textrm{(Subtracting 20.58 from both sides)}\\\\9.8t = 20.58 \;\;\;\;\;\; \textrm{ (Multiplying both sides by -1)}[/tex]
[tex]\textrm{Therefore }\\\\t = \dfrac{20.58}{9.8}\\\\t= 2.1 \textrm{ seconds}[/tex]
[tex]\textrm{Therefore, at = 2.1 seconds, the ball will reach its maximum height.}[/tex]
To find what this maximum height is, substitute t = 2.1 in the original equation and solve for h(t)
[tex]h(t)\;at\;t=2.1 \\h(2.1) = 4.9\cdot \:2.1^2+20.58\cdot \:2.1+25.48=47.089 \;meters\\\\[/tex]

While, find reflected points we are considering y-axis as mirror,
Then,
Reflection of point N(-3, 1) across the y-axis

A tree that is 3 feet tall is growing at a rate of 1 foot per year. A 5-foot tree is growing at a rate of 0. 75 foot per year. The ordered pair (t, h) represents the time in years, t, at which the trees are at height, h. Which ordered pair represents the number of years elapsed when the trees are at the same height?.
the ordered pair that represents the number of years elapsed when the trees are at the same height is (8,5). We were then asked to find the number of years elapsed when the trees are at the same height.
In this problem, we were given two different trees, one that is 3 feet tall and growing at a rate of 1 foot per year, and another that is 5 feet tall and growing at a rate of 0.75 feet per year. The ordered pair (3,1) represents the 3-foot tall tree growing at a rate of 1 foot per year and the ordered pair (5,0.75) represents the 5-foot tall tree growing at a rate of 0.75 feet per year.
To find the number of years elapsed when the trees are at the same height, we need to solve the equation:
3 + 1t = 5 + 0.75t
t = (5 - 3)/(1 - 0.75) = 2/0.25 = 8

Y = 2X + 10
Y = X + 2
Answer:
2+2%2%5+51%895%+8+81%9+61%+5%+8+%15+%
Answer:
(- 8, - 6 )
Step-by-step explanation:
y = 2x + 10 → (1)
y = x + 2 → (2)
substitute y = 2x + 10 into (2)
2x + 10 = x + 2 ( subtract x from both sides )
x + 10 = 2 ( subtract 10 from both sides )
x = - 8
substitute x = - 8 into either of the 2 equations and evaluate for y
substituting into (2)
y = - 8 + 2 = - 6
solution is (- 8, - 6 )

Determine whether each sequence has a negative common difference. Clearly explain your reasoning.
a). The sequence as represented in question a). is not an arithmetic sequence and hence, does not have a common difference.
b). The sequence formed by recording the daily odometer reading of a car after driving 15 miles each day does not have a negative common difference.
Which sequence has a negative common difference?It follows from the task content that the sequence which has a negative common difference be determined.
It follows that the common difference, by definition is the difference between successive terms a (n) of the sequence.
Therefore, common difference is usually given by; a (n) - a (n-1).
a). Since the given sequence is; 64, 32, 16, 8, ....
Since The common difference is; 32 - 64 ≠ 16 - 32 ≠ 8 - 16.
Hence, the sequence does not have a common difference and hence, is not an arithmetic sequence.
b). For a sequence involving the daily odometer reading of a car after driving 15 miles every day.
It follows that the recursive function for such a sequence would take the form; a (n) = a (n-1) + 15.
By comparison with the standard recursive function for arithmetic sequences, a (n) = a (n-1) + 15, it follows that the common difference, d = 15.
On this note, the common difference for the sequence is not a negative number.

What are the 3 different slope formulas?
The three different forms of slope formulas are m=(y-b)÷x, m=(y-y₁)÷(x-x₁), and m=(-A)÷B.
The slope gives the steepness of a straight line. The three different forms of the slope of a linear equation are slope-intercept form, point-slope form, and standard form.
From the equation of slope-intercept form y=mx+b, the slope is calculated using the formula, m=(y-b)÷x. Here, the slope is m and the y-intercept is b.
From the equation of the point-slope form (y-y₁)=m(x-x₁), the slope is calculated using the formula, m=(y-y₁)÷(x-x₁). Here, points on the line are x₁ and y₁.
From the equation of standard form Ax+By=C, the slope is m=(-A)÷B. Here, constants or integers are A, C, and B.
In general, the slope is calculated using the formula, m = (Δy)÷(Δx)= (y₂-y₁)÷(x₂-x₁). Here, in the line, the coordinate of the first point is (x₁, y₁), and the second point is (x₂, y₂).

A company rents paddleboards by charging a rental fee plus an hourly rate. Write an expression that represents the cost (in dollars) of renting a paddleboard for h hours.
The expression that represents the cost (in dollars) of renting a paddleboard for h hours is r + xh
How to determine the cost for h hoursFrom the question, we have the following parameters that can be used in our computation:
Cost of rents:
Charging a rental fee plus an hourly rate.
Using the above as a guide, we have the following:
Initial rental fee = r
Hourly rate = x
The cost for h hours can then be represented as
C(h) = Initial rental fee + Hourly rate * Number of hours
Substitute the known values in the above equation, so, we have the following representation

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
4x - 3y = 12 be equation (1)
Now , on simplifying the equation , we get
Adding 3y on both sides of the equation , we get
3y + 12 = 4x
Subtracting 12 on both sides of the equation , we get
3y = 4x - 12
Divide by 3 on both sides of the equation , we get
y = ( 4/3 )x - 4
It is of the form y = mx + b where m is the slope and b is the y-intercept
So , slope m₁ = 4/3
Now , the line is perpendicular to the line y = ( 4/3 )x - 4
So , the product of their slopes is -1
And , m₁ x m₂ = -1
Substituting the values in the equation , we get
