divide by -2

d= -9                                       d=9  

Answer:

d=(18-1)/-2l

Step-by-step explanation:

i-2dl=18

-2dl=18-l

/-2l        

d=(18-1)/-2l

The cost of a taxi ride can be calculated using the equation c = 1.75 + (m - 1/8) * 8 * 0.30, where c represents the total cost and m represents the total miles driven. Solving this equation for m when the total cost is $7.75 would yield the number of miles driven.

The subject of this question is the creation of an equation to calculate the cost of a taxi ride. According to the question, a taxi charges $1.75 for the first 1/8 mile and $0.30 for each additional 1/8 mile. First, we need to convert miles to 1/8 miles, since the pricing is based on this fraction. We know that each full mile is equal to 8 fractions of 1/8 mile. Therefore, to convert miles to 1/8 miles, we multiply the number of miles by 8.

Given this pricing structure, the costs associated with additional miles driven beyond the first 1/8 mile (which are already accounted for by the initial $1.75), can be represented by (m-1/8)*8*0.30. Here, (m-1/8) represents the additional miles traveled beyond the first 1/8 mile, and multiplying this by 8 converts these miles into 1/8 miles.

The total cost, c, can thus be represented by the equation c = 1.75 + (m - 1/8) * 8 * 0.30. If a ride cost $7.75, we can substitute this cost into the equation and solve for m to find the number of miles driven. This would give us the equation: 7.75 = 1.75 + (m - 1/8) * 8 * 0.30.

Answer~ A. y=3x-4

Explanation~ Look at the X column. Start with the first row, which is 5 in the x column and 11 in the y column. Looking back at the equation. As you can see, it has the same variables that are in the table. Replace the x with the 5 from the table.

*Remember to put the 5 in parenthesis; you must always do this when plugging in numbers into your equations*

If done correctly, your equation should now look like this:

y=3(5)-4

Following PEMDAS, the order you solve order of operations, you must first multiply, as Multiplication is before Subtraction. So, you must multiply the 5 and 3. 5×3=15, so, now your equation should look like:

y=15-4

Simply subtract 4 from 15, and you should get 11. Therefore,

y=11

Continue this process down through the table to double check your work.

Answer:

GB is 15 units

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The Centroid is a point of triangle where all 3 medians intersect

In this problem point G is the centroid of the triangle FDE

FA, EB and DC are medians of the triangle FDE.

Answer:

A. [tex]R=1,500+6x,\ x\le 800[/tex]

B. 584

Step-by-step explanation:

A band is performing at an auditorium for a fee of $1500.

In addition to this fee, the band receives 30% of each $20 ticket sold. Let x be the number of tickets sold, then these x tickets cost $20x. Calculate 30% of 20x:

[tex]20x\cdot 0.3=6x[/tex]

A. The total cost is

[tex]R=1,500+6x[/tex]

The maximum capacity of the auditorium is 800 people, so x≤800.

B. The band needs $5,000 for new equipment so

[tex]1,500x+6x\ge 5,000\\ \\6x\ge 3,500\\ \\x\ge \dfrac{3500}{6}\\ \\x\ge 583.333...[/tex]

So, it is enough 584 tickets to be sold.

The band's revenue equation is R = 1500 + 0.30 * 20 * x. To earn $5000 for new equipment, the band needs to sell at least 584 tickets, considering their fixed fee and the additional revenue from ticket sales.

Calculating Revenue for a Band's Performance

The band's total revenue (R) when x tickets are sold can be calculated using the equation: R = 1500 + 0.30 *20* x. This equation includes their fixed fee of $1500 plus the variable amount obtained from ticket sales, which is 30% of the ticket price ($20). For every ticket sold, the band adds $6 (30% of $20) to their revenue.

For the band to afford new equipment costing $5000, we need to determine how many tickets need to be sold. The equation becomes:

R = 1500 + 0.30 * 20 * x

$5000 = 1500 + 6 * x

$5000 - 1500 = 6 * x

$3500 = 6x

x = $3500 / 6

x = 583.33

Since the band cannot sell a fraction of a ticket, they would need to sell at least 584 tickets to meet their goal of $5000.

Final answer:

The equation of a line with a slope of 1 that passes through the point (2,5) in slope-intercept form is y = x + 3.

Explanation:

To write the equation of a line in slope-intercept form (y = mx + b), you need to know the slope (m) and the y-intercept (b). Since the slope is given as 1 and the line passes through the point (2,5), we can use the point-slope formula to find the y-intercept.

The point-slope formula is y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point the line passes through. Plugging in the values we have:

y - 5 = 1(x - 2) → y - 5 = x - 2 → y = x + 3

So, the equation of the line in slope-intercept form is y = x + 3.

Answer:

Step-by-step explanation:

Steps:

1. Let x = #

2. "Five less than six times a number" can be written as: 6x - 5

3. "is at least" is the same as "greater than or equal to" and can be written as: >=

4. "nine subtracted from two times that number" can be written as: 2x - 9

5. the equation is: 6x - 5 >= 2x - 9

6. solve for x by grouping the x variable terms on one side and the constants on the other side:

6x - 5 >= 2x - 9

-2x +5 -2X +5

4x >= -4

7. divide each side by 4, and you get: x = -1

The solution according to the given statement is "x = -1".

According to the question,

The equation will be:

By adding "5" both sides, we get

→ [tex]6x - 5+5 \geq 2x - 9+5[/tex]

→             [tex]6x \geq 2x-4[/tex]

By subtracting "2x" form both sides, we get

→     [tex]6x-2x \geq 2x-4-2x[/tex]

→             [tex]4x \geq -4[/tex]

→               [tex]x \geq -\frac{4}{4}[/tex]

Answer:

Step-by-step explanation:

We can model a line with slope-intercept form:

[tex]y = mx + b[/tex]

where [tex]m[/tex] is the slope and [tex]b[/tex] is the Y-intercept.

We know that the new line is parallel to the given line, so the two lines have the same slope, or [tex]m = \frac{3}{2}[/tex]:

[tex]y = \frac{3}{2}x + b[/tex]

To determine [tex]b[/tex], we just need to plug in the given point that the line passes through, [tex](-2, 3)[/tex]:

[tex]y = \frac{3}{2}x + b[/tex]

[tex](3) = \frac{3}{2}(-2) + b[/tex]

[tex]3 = -3 + b[/tex]

[tex]b = 6[/tex]

This gives us the following equation:

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

The equation of the line is y = (3/2)x + 6.

The equation of a line is given by:

y = mx + c

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

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of the line passes through the point (-2,3).

y = m(1)x + c

The equation of the line is parallel to the line whose equation is y=3/2x-4.

​This means,

y = (3/2)x - 4

This is in the form of y = m(2)x + c

m(2) = (3/2)

So,

m(1) = m(2)

Now,

(-2, 3) = (x, y)

y = m(1)x + c

3 = (3/2) x (-2) + c

3 = -3 + c

c = 3 + 3

c = 6

Now,

y = m(1)x + c

y = (3/2)x + 6

Thus,

The equation of the line is y = (3/2)x + 6.

To expand (2x + 4) (3x^2 + 5x + 7), draw a rectangle with six regions, multiply the terms in each region and add them together. The final expanded form is 6x^3 + 22x^2 + 34x + 28.

To expand the polynomial expression (2x + 4) (3x2 + 5x + 7), we will use the rectangle (or area) method. This involves drawing a rectangle divided into six regions, each representing a product of a term from the first binomial and a term from the second trinomial.

First, draw a 2x3 rectangle, with the dimensions representing the two terms in the first binomial and the three terms in the second trinomial.

Label the length of the rectangle with the three terms from the second trinomial, 3x2, 5x, and 7.

Label the width of the rectangle with the two terms from the first binomial, 2x and 4.

Fill in each of the six regions by multiplying the term at the end of the row by the term at the top of the column. For example, the top-left region would be 2x multiplied by 3x2, giving 6x3.

Continue filling in the other five regions: 2x times 5x is 10x2, 2x times 7 is 14x, 4 times 3x2 is 12x2, 4 times 5x is 20x, and 4 times 7 is 28.

Combine like terms to get the final expanded form: 6x3 + 22x2 + 34x + 28.

Answer:

The price was increased by 17.15%

Step-by-step explanation:

step 1

we have that

[tex]100\%+3.8\%=103.8\%=103.8/100=1.038[/tex]

Let

x -----> the price of a certain item

we know that

If a price increases by 3.8% a total of 5 times

then

The new price will be equal to multiply the original price by 5 times 1.038

so

[tex]x(1.038)(1.038)(1.038)(1.038)(1.038)=x(1.038)^5[/tex]

step 2

we have that

[tex]100\%-1.4\%=98.6\%=98.6/100=0.986[/tex]

we know that

If a price decreases by 1.4% a total of 2 times

then

The new price will be equal to multiply the actual price by 2 times 0.986

The actual price is [tex]x(1.038)^5[/tex]

so

[tex]x(1.038)^5(0.986)(0.986)=x(1.038)^5(0.986)^2=1.1715x[/tex]

[tex]1.1715-1=0.1715[/tex]

convert to percentage

[tex]0.1715*100=17.15\%[/tex]

therefore

The price was increased by 17.15%

Answer: The price increased by 17.149618%.

Step-by-step explanation:

Given that the price of a certain item increases by 3.8% = 0.038 a total of 5 times.

So every time the price was (1 + 0.038) = 1.038 times the original price.

So after 5 times the price is = [tex]1.038^5=1.205[/tex] times the original price.

Then it decreased by 1.4% twice. So the new price is = [tex]1.205\cdot\left(1-0.014\right)^{2}=1.17149618[/tex] times the original price.

So the percentage increase is = [tex]\left(1.17149618-1\right)\cdot100 \%=17.149618 \%[/tex]
