Answer:

The other half of the coordinate is 9  

Step-by-step explanation:

Given as :

The points is ( a , 5 )

The line equation is 4 x - 7 y = 1

Now if the given points lies on the given line , then it must satisfy the line equation

So , We have to  put the points on the given line

I. e 4 x - 7 y = 1

And the points as ( x , y ) = ( a , 5 )

So , 4 × a - 7 × 5 = 1

Or, 4 a - 35 = 1

or, 4 a = 1 + 35

Or , 4 a = 36

∴  a = [tex]\frac{36}{4}[/tex]

I.e  a = 9

So, The value of coordinates as ( a , 5 ) is ( 9 , 5 )

Hence The other half of the coordinate is 9  . Answer

Explanation:

The figure contains a table with the monthly payment on a a $100 loan in function of the number of months (term in months) and the annual percent rates (8.00%, 10.00%, 12.00%, 14.00%).

You find the monthly payment on an $100 loan for the terms of the installment loan obtained by Corey Griffin, in the cell resulting from the intersection of the row for 18 months and the column for the rate of 8.00%. That is 5.91.

The meaning of that value is that it must repaid $5.91 monthly, per each $100 of loan.

Hence, for the $1,000, you compute the monthly payment in this way:

Now, to find the finance charge, compute the total payments and subtract the amount of the loan:

Thus, the finance charge is $63.80 (option A).

1. The rate of change is -1 and the initial value is 1.

2. The graph represents Ava’s travel plans is graph (I).

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

1. We have the coordinates as C(3, -2) and D(-2, 3).

So, the rate of change of linear function is

= 3 - (-2) / (-2 -3)

= 3+ 2 / (-5)

= 5/ (-5)

= -1.

and, the initial values is where the independent variable is zero which is (1, 0).

1. The rate of change is -1 and the initial value is 1 (Option B). 2. The graph represents Ava’s travel plans is: option A (Graph 1).

The rate of change for a linear function is given by the slope of the line. The slope (m) can be calculated using the formula:

m = change in y / change in x

In this case, using the given points C (3, -2) and D (-2, 3):

[tex]\[ m = \frac{{3 - (-2)}}{{(-2) - 3}} = \frac{{5}}{{-5}} = -1 \][/tex]

So, the rate of change is -1.

The initial value of a linear function is the y-intercept, which is the y-coordinate when x = 0. Substituting (x, y) = (-2, 3) and m = -1 into y = mx + b, find b (initial value):

3 = -1(-2) + b

3 = 2 + b

3 - 2= b

b = 1.

Therefore, the correct answer is:

B. The rate of change is -1, and the initial value is 1.

Final answer:

After rounding to the nearest cent, the total payable sum is $419.78.

Explanation:

To calculate the total amount paid for an item with a sales tax, you first need to find the amount of sales tax by converting the tax rate from a percentage into a decimal. In this case, the sale amount is $399.79 and the sales tax is 5%.

Convert the percent to a decimal by dividing by 100:

5% ÷ 100 = 0.05

Next, multiply the sale amount by the decimal tax rate to find the amount of sales tax:

$399.79 × 0.05 = $19.9895

Since we usually round money to the nearest cent, round $19.9895 to $19.99.

Finally, add the amount of sales tax to the original sale amount to find the total amount paid:

$399.79 + $19.99 = $419.78

Therefore, the total amount paid including sales tax is $419.78.

The equation of the line that is parallel to y = -5x + 6 and passes through the point (-4, -1) in slope intercept form is y = -5x -21

Given that line passes through the point (-4, -1) and parallel to y = -5x + 6

We have to find the equation of line

Let us first calculate the slope of line having equation as y = -5x + 6

The slope intercept form of line is given as:

y = mx + c ---- eqn 1

where "m" is the slope of line and "c" is the y-intercept

Comparing the given equation of line y = -5x + 6 with slope intercept form y = mx + c,

we get the slope of line "m" = -5

We know that slope of two given parallel lines are always equal

Hence the slope of line which is parallel to line with equation y = -5x + 6 is also -5

Now we have to find the equation of line passing through point (-4, -1) with slope -5

Substitute (x, y) = (-4, -1) and m = -5 in eqn 1 to find "c" intercept

-1 = -5(-4) + c

-1 = 20 + c

c = -21

Substitute c = -21 and m = -5 in eqn 1 to get the equation of line

y = -5x + (-21)

y = -5x -21

Thus the equation of required line is found out as y = -5x -21

The standard form of a parabola with points through (2, 0) (3, 2) (4, 6)

is y = x² - 3x + 2 ⇒ 3rd answer

Step-by-step explanation:

The standard form of a parabola is y = ax² + bx + c, where a, b , c are constant

To find a , b , c

∵ The standard form of a parabola is y = ax² + bx + c

∵ The parabola passes through points (2 , 0) , (3 , 2) , (4 , 6)

- Substitute the coordinates of each point in the equation

Point (2 , 0)

∵ x = 2 and y = 0

∴ 0 = a(2)² + b(2) + c

∴ 0 = 4a + 2b + c

- Switch the two sides

∴ 4a + 2b + c = 0 ⇒ (1)

Point (3 , 2)

∵ x = 3 and 2 = 0

∴ 2 = a(3)² + b(3) + c

∴ 2 = 9a + 3b + c

- Switch the two sides

∴ 9a + 3b + c = 2 ⇒ (2)

Point (4 , 6)

∵ x = 4 and y = 6

∴ 6 = a(4)² + b(4) + c

∴ 6 = 16a + 4b + c

- Switch the two sides

∴ 16a + 4b + c = 6 ⇒ (3)

Subtract equation (1) from equations (2) and (3)

∴ 5a + b = 2 ⇒ (4)

∴ 12a + 2b = 6 ⇒ (5)

- Multiply equation (4) by -2 to eliminate b

∴ -10a - 2b = -4 ⇒ (6)

- Add equations (5) and (6)

∴ 2a = 2

- Divide both sides by 2

∴ a = 1

Substitute the value of a in equation (4) to find b

∵ 5(1) + b = 2

∴ 5 + b = 2

- Subtract 5 from both sides

∴ b = -3

Substitute the value of a and b in equation (1) to find c

∵ 4(1) + 2(-3) + c = 0

∴ 4 - 6 + c = 0

- Add like terms

∴ -2 + c = 0

- Add 2 to both sides

∴ c = 2

Substitute the values of a , b , c in the standard form above

∵ y = ax² + bx + c

∵ a = 1 , b = -3 , c = 2

∴ y = (1)x² + (-3)x + (2)

∴ y = x² - 3x + 2

The standard form of a parabola with points through (2, 0) (3, 2)

(4, 6) is y = x² - 3x + 2

There is another solution you can substitute the x-coordinate of each point in each answer to find the corresponding value of y, if the value of y gives the same value of the y-coordinate of the point for the three points then this answer is the standard form of the parabola

The fractions like [tex](\frac{8}{2}), (\frac{16}{4}), (\frac{44}{11} )[/tex] could  represent the part of the beads that are red.

Step-by-step explanation:

The given question is incomplete. Here is the complete question:

Miranda is braiding her hair. Then she will attach beads to the braid, she wants 1/3 of the beads to be red. If the greatest number of beads that will fit on the braid is 12, what other fractions could represent the part of the beads that are red?

Now, total number of beads to be fit on the braid   = 12

The desirable amount of red beads = 1/3

So, now as the number of red beads Miranda can use

= 1/3 ( Total beads used)  

= [tex]\frac{1}{3}  \times 12 = 4[/tex]

or, out of total 12 beads, 4 beads are red.

⇒The total number of red beads = 4

Hence,  the fractions like [tex](\frac{8}{2}), (\frac{16}{4}), (\frac{44}{11} )[/tex] could represent the part of the beads that are red.

Miranda can use fractions with 12 in the denominator to represent the portion of red beads on her braid. Possible fractions include 1/12, 2/12, 3/12, 4/12, 5/12, 6/12, and so on up to 11/12.

Miranda wants 1/12 of the beads to be red on her braid. Since the greatest number of beads that will fit on the braid is 12, the other fractions that could represent the part of the beads that are red must also be fractions with 12 in the denominator to be comparable.

Possible fractions representing red beads out of a total of 12 beads are:

These represent all the simple fraction options for the number of red beads based on the constraint of having a maximum of 12 beads.

C) The probability that Jacob gets a mule deer is 1/7.

Step-by-step explanation:

Let us assume the number of mule deer in the woods  = m

So, the number of whitetail deer  = 6 x ( Number of mule deer) = 6 (m) = 6 m

Also, the total number of deer = Mule deer + whitetail deer

                                                    =  m + 6 m = 7 m

Let E: Event of Picking a mule deer in the woods.

[tex]\textrm{P(E)}  = \frac{\textrm{Number of favorable observations}}{\textrm{ Total number of observations }}[/tex]

So, here [tex]\textrm{P(Picking a mule deer )}  = \frac{\textrm{Number of Mule deers in the woods}}{\textrm{ Total number of deer }}  = \frac{m}{7m}  = \frac{1}{7}[/tex]

or, P(E) = 1/7

Hence, the  probability that Jacob gets a mule deer is 1/7.

Answer:

C) The probability that Jacob gets a mule deer is 1/7.

Also, the total number of deer = Mule deer + whitetail deer

                                                   =  m + 6 m = 7 m

Let E: Event of Picking a mule deer in the woods.

So, here

or, P(E) = 1/7

Hence, the  probability that Jacob gets a mule deer is 1/7.

To find the correct dimensions of a scaled drawing or the actual dimensions based on a scale factor, multiply the scaled dimensions by the denominator of the scale factor. For a scale factor of 1/200, if a scaled drawing has dimensions of 1 meter by 1 meter, the actual dimensions would be 200 meters by 200 meters, yielding an area of 40,000 square meters.

To determine the correct dimensions of a scaled drawing or the actual dimensions based on a scale factor, it is essential to understand the ratio that the scale factor represents. If the scale factor for a drawing is given as 1/200, it signifies that every unit of measurement on the drawing represents 200 of the same units in the actual size.

For example, let's assume you have a scaled drawing with dimensions of 1 meter by 1 meter, and the scale factor is 1/200. To find the actual dimensions, you would multiply the scaled dimensions by the scale factor's denominator:

Once you know the actual dimensions, finding the area involves multiplying the length by the width. Using our example:

When creating or analyzing scale drawings, remember to apply the scale factor consistently to each dimension to obtain accurate results.

Final answer:

There are 15 seventh-grade students who will not be able to ride on a bus for the field trip, as the total bus seating capacity is for 220 students and there are 235 students going on the trip.

Explanation:

The subject of this question is Mathematics, specifically a problem involving division and subtraction to determine the number of students who will not have a seat on the buses. To solve this, we need to calculate the total seating capacity of all buses and then find the difference between the number of students and the total seating capacity.

Each bus has 22 seats and each seat can accommodate 2 students, so each bus can carry 22 x 2 = 44 students. There are 5 buses, so the total seating capacity is 5 x 44 = 220 students.

There are 235 seventh-grade students going on the field trip. To find out how many will not be able to ride the bus, we subtract the total seating capacity from the number of students: 235 - 220 = 15 students will not be able to ride on a bus for the field trip.

Then, it is the graph of translated 3 units upward, which means that the graph of g(x) is 3 units above the graph of f(x).

The graph of g is 3 units above the graph of f(x), the correct option is A.

The graph is a mathematical representation of the relation between two objects.

It helps in determining the function that fits best for the data obtained.

A function is a mathematical statement that defines a relationship between a dependent and an independent variable.

A function always has a defined range and domain, domain is all the value a function can have as input and range is all the value that a function can give as output.

The function f(x) = 2x

g(x) = 2x+3

Both functions are a straight line, an equation of a straight line is given by y =mx +c, m is the slope of the line and c is the y intercept.

In the function f(x), the slope is 2 and the intercept is 0

In the function g(x), the slope is 2 and the intercept is 3.

As the intercept is 3, the g(x) is 3 units above the graph f(x).

Part 12) The table represent a direct variation. The equation is [tex]y=0.4x[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Part 11)

For x=0.5, y=9

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=9/0.5=18[/tex]

For x=3, y=54

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=54/3=18[/tex]

For x=-2, y=-36

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=-36/-2=18[/tex]

For x=1, y=18

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=18/1=18[/tex]

For x=-8, y=-144

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=-144/-8=18[/tex]

The values of k is the same for each ordered pair

therefore

The table represent a direct variation

The linear equation is

[tex]y=18x[/tex]

Part 12)

For x=-5, y=-2

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=-2/-5=2/5=0.40[/tex]

For x=3, y=1.2

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=1.2/3=0.40[/tex]

For x=-2, y=-0.8

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=-0.8/-2=0.4[/tex]

For x=10, y=4

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=4/10=0.4[/tex]

For x=20, y=8

Find the value of k

[tex]k=y/x[/tex] -----> [tex]k=8/20=0.4[/tex]

The values of k is the same for each ordered pair

therefore

The table represent a direct variation

The linear equation is

[tex]y=0.4x[/tex]
