Graph A (1,6)

slope is 4/1

This is called system of equations because you are searching a pair of numbers that inserted as x and y verify both equations at the same time.

To solve a system of equation you have to use one equation to express one variable as a function of the other, and substitute the result in the second equation.

In your case you have

y = x - 2

So your y  variable will be always equal to x - 2 , even in the second equation. Then we can write

x - 2 = 4x + 1

Here I replaced the "value" of y in the second equation.

Now you have an equation in one variable that you can solve as usual

x - 2 = 4x + 1

4x - x = - 2 - 1

3x = -3

x = -1

With a value for x you can substitute in one of the two equations and obtain y. Because both equations has to be valid at the same time, both equations must give you the same number for y.  Let's try:

y = x - 2

y = - 1 - 2

y = -3

and, with the second equation

y = 4x + 1

y = 4 ( - 1 ) +  1

y = - 4 + 1

y = -3

It works! Then our solution is given by x = -1 and y = -3.

To graph this, simply plot these coordinates.

Answer:

The equation of the line is: y=2x + 3

Hey there!

PEMDAS simply means (the OVERALL question answer)

• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction

Here’s an example

24 - 4^2 + 2 * 4

= 24 - 16 + 2 * 4

= 24 - 16 + 8

= 8 + 8

= 16

Thus, the answer for that equation is: 16

Often people remember PEMDAS by saying. (So, I’d advise you think of it like that way as well!)

PEMDAS is the order that you solve a problem.

PEMDAS stands for:

Parenthesis

Exponents

Multiplication and Division

Addition and Subtraction

If you have an equation or expression that you need to solve, you solve it in this order. You do the parenthesis first, then you solve the exponents, then you do the multiplication and division from left to right, and last you do addition and subtraction from left to right.

In the equation

2 + 3 * 5,

first you would do 3 * 5 because multiplication is before addition.

2 + 15

Then you would do the addition to get the answer:

17.

Answer:

Then the count of 1 cent stamps is 15 −x. So for total cost we have. [45x + 1(15 − x)]cents = $4.55. but there are 100 cents in 1 dollar so we change the above to. [45x +1(15 −x)] 100 = 4.55. Multiply both sides by 100. 45x + 15− x = 455. 44x = 440.

Step-by-step explanation:

Answer: If you meant (x^2 + 5x - 36)/(x^2-16) then the answer is: (x+9)/(x-4)

Step-by-step explanation:

This is just factoring, you can use guess and check.

If you take just the numerator: x^2+5x-36 and factor. To factor consider -36, and the multiples that can add up to 5 (from 5x).

x^2 + 5x - 36/(x^2-16)

The denominator is actually a rule of (a+b)(a-b) which in this case (x+4)(x-4)

(x+9)(x-4)/(x-4)(x+4)

Now just divide like terms which is the (x-4)/(x-4)=1

(x+9)/(x+4)

keeping in mind that a year has 12 months, so that means that 18 months is really 18/12 of a year.

Answer:

$35 = $12 + $1.85x

Step-by-step explanation:

the total is 35 so it is alone on the left side of the equal sign

then 5 + 7 is 12 and he has to spend $12

rides are 1.85 each so there is a x next to it

Answer:

The radius = 13 square inches.

Explanation:

The profit per bag for the bags sold at $1 each is 0.35

The correct option is: (D)

Profit is the positive financial gain remaining after all costs, taxes, and expenses have been deducted from total sales.

Profit per bag for the bags sold at $1 each be,

Profit = (Estimated sales -(Estimated Sales* Variable cots +Fixed cost))/Estimated Sales

We know,

Estimated sales= 1600000

Variable cost = 0.40

Fixed cost= 400000

So, Profit = [tex]\frac{1600000-(1600000*0.40+400000)}{1600000}[/tex]

               = [tex]\frac{1600000-(1040000)}{1600000}[/tex]

              = [tex]\frac{560000}{1600000}[/tex]

              = 0.35

Hence, the profit per bag be 0.35.

Question:

In three days Tina sold 15 boxes. On the second day, she sold 1 more than on the first. On the third day, she sold 5 more than on the first. How many boxes did she sell on the third day?

Answer:

8. Tina sold eight boxes on the third day.

Step-by-step explanation:

Three days, 15 boxes.

On the first day, Tina sold 3 boxes.

On the second, she sold one more than on the first. (4)

On the third day, she sold five more than on the first. (8)

 3 + 4 = 7

7 + 8 = 15

So your answer would be:

Tina sold eight boxes on the third day.

100% = $143.74

1% = 100%/100 = 143.74/100 = $1.4374

5.3% = 1%×5.3 = 1.4374 × 5.3 = $7.61822

$143.74 + 5.3% = $143.74 + $7.61822
