Answer:

1) x+2y=7

+3x-2y=5

2)After adding like terms your answer is

4x-0=12

Divide the left side from the right by 4

and your x= 3.

3)Then add the x value(3) into one of the 2 equations

x+2y=7

3+2y=7, Subtract 3 from the left and right side=7-3=4

2y=4, divide by two and y= 2...

Use the elimination method..Substitute x=3 and y=2 into the second equation and you should come to the same answer...

Step-by-step explanation:

The seller receives x+3 dollars for each gallon of cider sold in the fundraiser.

Use the concept of fraction defined s:

A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p/q.

Given that,

Apple cider is being sold for a fundraiser.

The company that makes the cider receives $x$ dollars for each gallon sold.

The seller receives the remaining amount of money after the company's share.

A total of 15 gallons of cider were sold.

The total amount of money from selling the cider is $15x + 45$ dollars.

To find out how much money you receive for each gallon of cider sold, Set up an equation based on the given information.

Assume that you receive y dollars for each gallon of cider sold.

Since you sold 15 gallons of cider for 15x + 45 dollars,

Then write the equation:

15y = 15x + 45

To find the value of y,

Divide both sides of the equation by 15:

[tex]y = \frac{15x + 45}{15}[/tex]

Simplifying the equation further, we get:

y = x + 3

Therefore,

You receive x + 3 dollars for each gallon of cider that you sell.

Answer:

B

Step-by-step explanation:

I just took this assignment on edge :)

Answer and Step-by-step explanation:

The angle that is formed is an acute angle, which means it has to be less than 90 degrees.

The length from the point to the origin (hypotenuse) is 25 (obtained by using the distance formula).

The height of the triangle is 24, since it goes up 24 units, and the base of the triangle is 7, since it goes right 7 units.

Answer:

the degree of the polynomial

Step-by-step explanation:

Given

Polynomial equation

Required

What does the sum of the multiplicities add up to

To answer this question, I'll make use of the following polynomial.

[tex]p(x) = x^3 - 7x^2 + 15x - 9[/tex]

When factorized, the polynomial is:

[tex]p(x) = (x - 1)(x - 3)(x-3)[/tex]

[tex]p(x) = (x - 1)(x - 3)^2[/tex]

x-1 can be expressed as [tex](x - 1)^1[/tex]

So, we have:

[tex]p(x) = (x - 1)^1(x - 3)^2[/tex]

The sum of multiplicity (M) of the equation is 3.

This is so because

[tex]x - 1[/tex] occurred one time in [tex]p(x) = (x - 1)(x - 3)^2[/tex]

[tex]x - 3[/tex] occurred two times in [tex]p(x) = (x - 1)(x - 3)^2[/tex]

[tex]Sum= 1 + 2[/tex]

[tex]Sum= 3[/tex]

The degree of [tex]p(x) = x^3 - 7x^2 + 15x - 9[/tex] or [tex]p(x) = (x - 1)^1(x - 3)^2[/tex] is 3.

This implies that:

[tex]Sum = Degree = 3[/tex]

Hence: Option (a) answers the question

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex] and [tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a

Given

Answer:

1) 35

Step-by-step explanation:

1. First, you have to realize that a straight line is 180 degrees.

Why is this important to know? Well you know that all angles of a triangle added up together HAS to equal 180, it'll be a straight line

2. Add 40 and 105, this gives you 145.

3. Subtract 145 from 180, and you should get 35, which is x.

You can check this by adding 40, 105, and 35 together.

Answer:

x = 9

y = 6

Step-by-step explanation:

Since, RS bisects AB,

5x - 9 = 5y + 6

5x - 5y - 9 = 6

5x - 5y = 6 + 9

5x - 5y = 15

x - y = 3 -------(1)

And RS = 36

Since, RS = RT + TS

(3y - 1) + (2y + 7) = 36

5y + 6 = 36

5y = 30

y = 6

From equation (1),

x - 6 = 3

x = 9

Answer:

Step-by-step explanation:

For the slope of a line formula to be used,

Expression: y = 7x + 25

Cost of 12 portraits = AED 109

Step-by-step explanation:

Given that:

Sitting fee charged by studio = AED 25

Charges for each portrait sheet = AED 7

Let,

x be the number of photographs taken.

y be the total cost.

y = 7x + 25

Total cost for 12 portrait sheets.

x = 12

y = 7(12) + 25

y = 84+25 = AED 109

Hence,

Expression: y = 7x + 25

Cost of 12 portraits = AED 109

Answer:

960 ft

Step-by-step explanation:

We need to find the surface area. To do this, let's see the shapes that are present. There are two triangles with a base and height of 9 and 12, respectively. There is one rectangle with a base and height of 24 and 15, one with base and height of 24 and 12, and finally one with a base and height of 24 and 9.

The areas are:

Triangles: 1/2bh = 1/2(9)(12) = 48 (there are two of these)

Rectangle 1: bh = (24)(15) = 360

Rectangle 2: bh = (24)(12) = 288

Rectangle 3: bh = (24)(9) = 216

Adding all these areas together, we get 960.

Thus, Monique will need 960 feet of fabric to cover the prism.

Answer:

100 is always divisible by 4. Therefore it doesn't matter which number is up front.

the two other digits are important because there are 2-digit-numbers that are not divisible by four. "14" is not divisible by four, but "24" is.

34 isn't divisible, 44 is, 54 isn't.

So both digits will need to form a number that is divisible by 4, or it will not work.
