well, clearly 4 > 1.

Answer:

f(x) has a greater slope.

Step-by-step explanation:

The slope of a function in the form of y=Mx+C is represented by the letter M, so the slope in the function F(x) =4.

Now when you have a function but you only have a table to evaluate it, to calculate the slope you have the next formula:

[tex]m=\frac{y^{2}- y^{1}}{x^{2} -x^{1} }[/tex]

You just have to pick two points from the table to use in the formula, we´ll use (4,7) as our point 1 and

(6,9) as our point 2.

This means that:

[tex]x^{1}=4[/tex] [tex]y^{1}=7[/tex]

[tex]x^{2}=6[/tex] [tex]y^{2}=9[/tex]

Now you just put it into the formula:

[tex]m=\frac{9-7}{6-4}[/tex]

[tex]m=\frac{2}{2}[/tex]

[tex]m=1[/tex]

Now that you have both slopes, you can see that the slope of g(x)=1 and the slope of f(x)=4, and you can see that f(x) has a greater slope thatn g(x).

Answer:

$0.20

Step-by-step explanation:

A dozen of pencils = $2.40

1 pencil = $2.40 ÷ 12 = $0.20

PLEASE DO MARK ME AS BRAINLIEST UWU

ALSO, DO HAVE A GREAT DAY ;)

The unit price per pencil is determined by dividing the total cost of the pencils ($2.40) by the total number of pencils (12), giving a result of $0.20 per pencil.

To find the unit price per pencil, you would divide the total cost by the total number of items.

In this case, the total cost is $2.40 and there are twelve pencils, so the calculation is $2.40 ÷ 12.

This will give you the unit price per pencil.

Using the numbers provided, $2.40 (the total cost) divided by 12 (the total number of pencils) equals $0.20.

So, the unit price of a pencil is $0.20.

205/6

Step-by-step explanation:

The question simply asks us to plug in 45 minutes into the given equation. In the graph, we see that y-axis is defined to be time. Therefore we set y=45 and solve for x.

45=-6/5x+86

-41=-6/5x (subtract 86 from both sides)

-41*(-5)=-6/5x*(-5) (multiply both sides by -5)

205=6x (divide both sides by 6)

205/6=x

Answer:

 (x-2)(x-7)

Step-by-step explanation:

x2 – 9x + 14 = x² - 2x - 7x + 14

                    = x(x-2) - 7(x-2)

                    = (x-2)(x-7)

Answer:

Factor of x² – 9x + 14 is:

(x-2)(x-7)

Step-by-step explanation:

We have to find the factors of:

x² – 9x + 14

On splitting the middle term, we get

x² -7x -2x +14

which could also be written as:

x(x-7)-2(x-7)

which is equivalent to:

(x-2)(x-7)

Hence, Factor of x² – 9x + 14 is:

(x-2)(x-7)

Answer:

11

Step-by-step explanation:

arrange from smallest to greatest:

2,2,5,10,12,13,18,24

The median is the middle name.

If you have two middles, the median is the average of them.

So you have 2 middles, 10 and 12.

The average of 10 and 12 is given by (10+12)/2=11

Hello There!

The median is the middle number of the data set so let’s find it!

Step 1. Order your numbers from least to greatest so after we have done that, our numbers would be 2,2,5,10,12,13,18,24

Step 2. We want to cross of a number at the beginning so Starting with 2 and the last number 18 and do that either until we get to one number in the middle or two numbers.

Step 3. There is no one number in the middle but we have the numbers 10 and 12 so we add them together which gives us a sum of 22 and then divide 22 by 2 and we get a quotient of 11.

Our median is 11.

Answer:

n=m(x)

Step-by-step explanation:

n is the dependent variable m is the independent variable.

how many cartons, depends on how many liters are in a carton.

how many he needs to buy= the amount in carton× how ever much is in his recipe

for example

if they're are let's say 1.5 liters per carton than m=1.5. and if he needs 15 liters than n= 15

than the equation is

[tex]15 = 1.5 \times x[/tex]

x is how many cartons he needs to buy

solve for x by dividing both sides of the equation by 1.5

[tex]15 \div 1.5 = x[/tex]

Answer:

2

Step-by-step explanation:

Center: (−4,3)

Radius: 2

Answer:

radius = 2

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r the radius

Given

x² + y² + 8x - 6y + 21 = 0

Use the method of completing the square to obtain standard form

Collect the x- terms and y- terms together and subtract 21 from both sides

x² + 8x + y² - 6y = - 21

add ( half the coefficient of the x/y terms )² to both sides

x² + 2(4)x + 16 + y² + 2(- 3)y + 9 = - 21 + 16 + 9

(x + 4)² + (y - 3)² = 4 ← in standard form

with centre (- 4, 3) and radius = [tex]\sqrt{4}[/tex] = 2

Answer:

D. 76.5

Step-by-step explanation:

The summation sign means that it is the sum of the expression for all values of n upto 6.

n = 2 below the summation sign means that n starts from 2.

∑(n-1)!/2 from n= 2 to n=6

= (2-1)!/2 + (3-1)!/2 + (4-1)!/2 + (5-1)!/2 + (6-1)!/2

= 1!/2 + 2!/2 + 3!/2 + 4!/2 + 5!/2

= 1/2 + 2*1/2 + 3*2/2 + 4*3*2/2 + 5*4*3*2/2

= 1/2 + 2/2 + 6/2 + 24/2 + 120/2

= 0.5 + 1 + 3 + 12 + 60

= 76.5

Option D which simplifies to 11y +17 = 11y -10 has no solution since the left and right sides of the equations aren't equal after simplifying.

We are tasked with determining which equation has no solution among the given options: A) 13y + 2 - 2y = 10y + 3 - y, B) 9(3y +7) - 2 = 3(-9y + 9), C) 32.1y + 3.1 + 2.4y - 8.2 = 34.5y - 5.1 and D) 5(2.2y + 3.4) = 5(y - 2) + 6y. The equation without a solution will be the one in which the variables cancel out and the remaining numbers are not equal.

Solving the equations, starting with A, by combining like terms, we have 11y + 2 = 9y + 3, this eventually gives us y = 0.5.  Option B, simplifying gives us 27y + 63 = -27y + 27, therefore y = -1.33. For C, we simplify to 34.5y + 3.1 = 34.5y - 5.1. Because both sides of the equation have equal coefficients for y, this results in 34.5y = 34.5y, which holds true for any value of y. Hence, the equation has infinitely many solutions. Option D simplifies to 11y +17 = 11y -10. Here, we see that 11y = 11y is true, however, the constants are not equal (i.e. 17 does not equal -10). Thus, option D is the equation with no solution.

Final answer:

The coordinates that form a square when paired with (-3, -2) and (-5, -2) are (-3, 0) and (-5, 0). The sides of the square are 2 units long, and by moving perpendicularly up by 2 units from each given point, we find the other two vertices of the square.

Explanation:

The student has asked which set of coordinates, when paired with (-3, -2) and (-5, -2), would result in a square. To find the coordinates that complete the square, we need to consider that the diagonals of a square are equal in length and bisect each other at right angles. The two given points (-3, -2) and (-5, -2) form a side of the square that is parallel to the x-axis and 2 units long. Since a square has all sides equal, the other two vertices of the square will be 2 units away from these points but in a perpendicular direction.

Here's how we calculate it step by step:

First, we determine the length of the side of the square by calculating the distance between the points (-3, -2) and (-5, -2), which is 2 units.

Next, we move 2 units perpendicularly from each point which can be done by either keeping the x-coordinate constant and changing the y-coordinate or vice versa. Since we want to be perpendicular to the x-axis, we change the y-coordinate.

The change in the y-coordinate could be either upwards (+2) or downwards (-2). Considering the y-value of the given points, one possible set of coordinates for the other two vertices are (-3, 0) and (-5, 0).

Therefore, the coordinates (-3, 0) and (-5, 0), when paired with (-3, -2) and (-5, -2), form a square.

Answer:

f(x)^-1 = 1/3x - 2

Step-by-step explanation:

Replace f(x) with y and solve:

y = 3x + 6

Swap x and y

x = 3y + 6

Now isolate y

x/3 = 3y/3 + 6/3

1/3 x = y + 2

1/3 x - 2 = y + 2 - 2

y = 1/3x - 2 or f(x)^-1 = 1/3x - 2

For this case we have the following function:

[tex]f (x) = 3x + 6[/tex]

We must find the inverse of the function, then:

Replace f (x) with y:[tex]y = 3x + 6[/tex]

We exchange the variables:

[tex]x = 3y + 6[/tex]

We solve for "y":

Subtracting 6 on both sides of the equation:

[tex]x-6 = 3y[/tex]

Dividing between 3 on both sides of the equation:

[tex]y = \frac {x} {3} - \frac {6} {3}\\y = \frac {x} {3} -2[/tex]

We change y by [tex]f ^ {- 1} (x)[/tex], and finally we have:

[tex]f ^ {- 1} (x) = \frac {x} {3} -2[/tex]

ANswer:

[tex]f ^ {- 1} (x) = \frac {x} {3} -2[/tex]
