y = -5x - 3

-5x - y - 3 = 0

Substitute

-5x - (-5x - 3) - 3 = 0

Distributive Property

-5x + 5x + 3 - 3 = 0

Combine Like terms

0 + 3 - 3 = 0

0 + 0 = 0

Answer:

Subtracting a number is the same as adding the opposite of the number

Step-by-step explanation:

Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.

Step-by-step explanation:

Taking the readings from the graph

x ....  y0 .... 22 .... 64 .... 106 .... 14

Rate of change for the given line is:

(6 - 2)/2 = 4/2 = 2y- intercept is 2

Equation for the line is:

y = 2x + 2

For the point (40, 76) we can verify with the equation:

40*2 + 2 = 82

The point (40, 76) is close the line but the line doesn't pass through it.

Answer:

x | y

0 | 2

2 | 6

4 | 10

6 | 14

Equation of the line is

[tex] \frac{y - 2}{x - 0} = \frac{6 - 2}{2 - 0} \\ \frac{y - 2}{x} = \frac{4}{2} = 2 \\ y - 2 = 2x \\ y - 2x = 2\\ \boxed{y=2x+2}[/tex]

When x=40, y will be (2×40)+2 =82

So the point should pass through (40,82) and not (40,76).

HELP ASAP A furniture manufacturer must pay $16.91 to make a certain kind of chair, which it can sell for $55.75. If the manufacturer has starting overhead costs of $18,340, not including production costs, how many chairs must it sell to realize a profit of $24,850, to the nearest chair?
a. 1,112
b. 918
c. 775
d. 640

(10 points and brainliest if the answer is right)

Answers

Answer:

A. 1,112

Step-by-step explanation:

The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Option A is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's start by finding the profit per chair:

So,

Profit per chair = Selling price - Production cost

= $55.75 - $16.91

= $38.84

Next, we need to determine how many chairs the manufacturer needs to sell to make a profit of $24,850:

Profit = Profit per chair x Number of chairs sold - Overhead costs

$24,850 = $38.84x - $18,340

$43,190 = $38.84x

x = 1,112.49

Rounding to the nearest whole number, the manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Therefore,

The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Find an equation for the line below. Thanks !

Answers

Answer:

[tex]\huge\boxed{y=\frac{1}{4}x + \frac{13}{4}}[/tex]

Step-by-step explanation:

In order to find the equation to this line, we need to note that we see two points on this graph. Using these two points, we can use them to find the slope of the graph and use one to find the y-intercept.

We know that the slope of a line is defined by [tex]\frac{\Delta y}{\Delta x}[/tex] (change in y / change in x). Therefore, we can use our two points that we know - (-5, 2) and (3, 4) to find the slope.

The change in y is [tex]4 - 2 = 2[/tex], and the change in x is [tex]3 - (-5) = 3+5= 8[/tex]. Therefore, our slope is [tex]\frac{2}{8} = \frac{1}{4}[/tex].

Now that we know our slope, our equation in slope-intercept form looks something like this.

[tex]y = \frac{1}{4}x + b[/tex]

However, we still have b to solve for. We can solve for this by substituting a point we already know into the equation. Let's substitute (3, 4) inside.

[tex]4 = \frac{1}{4} \cdot 3+b[/tex] [tex]4 = \frac{3}{4} + b[/tex] [tex]b = \frac{16}{4}- \frac{3}{4}[/tex] [tex]b = \frac{13}{4}[/tex]

So now we know that the y-intercept is [tex]\frac{13}{4}[/tex]. Plugging that into our equation finishes it off, leaving our final equation to be [tex]y = \frac{1}{4}x + \frac{13}{4}[/tex].

A taxi service charges a base fee of $5.00 for each fare. In addition, the service charges a $1.75 per minute fee. Which equation relates the total cost of a fare, , to the length of the ride, in minutes, ?

Answers

Answer:

Equation is = 5+1.75m

Step-by-step explanation:

Given that,

A taxi service charge is $5.00 for each fare.

In addition, the service charges a $1.75 per minute fee.

It means, for every minute, $1.75 increases with time and $5.00 is fixed.

ATQ,

Total cost = 5+1.75m

Where m is time in minutes

Hence, the required equation is "5+1.75m".

Find the slope:
(3,-5) and (-7,-6)

Answers

the slope is 0.1 or one tenth as a fraction.

slope equation:

change in Y divided by change in X

**underlined numbers are x values and bold numbers are y values**

(3,-5) and (-7, -6)

our two Y values looking at the coordinates are -5 and -6, since coordinates are (x,y)

our two X values are 3 and -7

now plug these into the equation:

-5 - (-6)

------------

3 - (-7)

**PAY ATTENTION TO THE SIGNS**

now the numerator is -5+6 which is 1

and the denominator is 3+7 which is 10

that makes 1/10 as a fraction -your slope

simplify it and you have:

The band at charles high school had a concert for charity. They raised $15,000. Adult tickets were $5 each and student tickets were $3 each. The members of the band sold a total of 4,000 tickets. How many student tickets did they sell

Answers

Answer:

Adults =1500 and student= 2500

Step-by-step explanation:

Step one:

GIven data

let Adults be x and student be y in numbers

so

5x+3y=15000------------1

x+y=4000---------------------2

from 1

x=4000-y, put this in 2, we have

5(4000-y)+3y=15000

20000-5y+3y=15000

-2y=15000-20000

-2y= -5000

2y=5000

divide both sides by 2

y= 2500

put y= 2500 in 2

x+2500= 4000

x= 4000-2500

x=1500

Jennifer received a $25 gift certificate from a music store. She can use it to buy 2 CD’s and 5 cassettes or 1 CD and 15 cassettes. Find the cost of 1 CD and 1 cassette.
Please help A.S.A.P.

Answers

Answer:

CD = 10$

Cassette = 1$

Step-by-step explanation:

ok, time to use some variables

C = CD

S = Cassette

2c + 5s = 25$

1c + 15s = 25$

the second equation has 1 less CD and 10 more Cassettes, therefore 1c = 10s

Now we can calculate how many Cassettes we can buy

1c - 1c = 0c

15s + 10s = 25s

This means that 25s = 25$

therefore 1s = 1$

since we know that 10s = 1c, and 1s = 1$, then we can figure out how many dollars the CD is

1c = 10s = 10$

1c = 10$

Hey there!

Given;

The sum of two numbers is 45.

One of them is 27.

Let next number is "x".

So, Add "x" and "27" and show it is equal to 45.

Or, x+27 = 45

Therefore, x+27 = 45 is the required equation.
