what is the y ?

x+2y=7
3x-2y = 5​

Answers

x+2y=7 everything times (-3)
So it’s gonna be
-3x-6y=-21
3x-2y=5
We remove the (-3x) from the first and (3x) from second
And add everything that’s left
-6y-2y=-21+5
8y(cuz - and - is +)
8y=16
Y=16/8
Y=2

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...

Answers

Answer:

The answer is the second table (the one with B and C.)

Step-by-step explanation:

You know this, because the other tables are just based on patterns and the x and y values have nothing to do with each other. However, for the second table, the b value times 3 equals the c value. This is how you know the table shows a proportional relationship, and this is key to solving this problem.

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

You sell apple cider for a fundraiser. For each gallon of cider you sell, the company that makes the cider receives $x$ dollars, and you receive the remaining amount. You sell $15$ gallons of cider for $\left(15x+45\right)$ dollars. How much money do you receive for each gallon of cider that you sell?

Answers

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.

I wanna say -1/3 -6 orrrrr -1/3 6

Write an equation of the line with a slope of -7 and y-intercept of 1​

Answers

Answer:

y = -7x + 1

Step-by-step explanation:

You put it in the form y = m*x + b

Where m = the slope, so -7 and b = the y-intercept, so 1.

This means it's y = -7x + 1

Note: this answer assumes the equation can be put in slope-intercept form.

Answer:

y = -7x + 1

Step-by-step explanation:

Slope-intercept form, or y = mx + b format, is written in a way that easily reflects the slope and y-intercept of a line. The m, or the coefficient of the term with the x, represents the slope. The b represents the y-value of the y-intercept.

Therefore, substitute the number -7 and 1 in place of those variables. Since -7 is the slope, substitute in place for m. Since 1 is the y-intercept, substitute in place of b. This gives us the equation y = -7x + 1.

Answers

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

Which statements accurately compare the different functions check all that apply (multiple answers)

Answers

3 Answers:A) The quadratic and absolute value functions share a y-intercept. B) The square root and quadratic function share an x-intercept. D) The square root function does not have a y-intercept.

===================================================

Explanations:

Choice A) This is true. The y intercept is where graph crosses the y axis. The blue V shaped graph and the orange parabola cross at 8 on the y axis. Therefore, they have the same y intercept.Choice B) This is true. The x intercept is the same for both the orange parabola and red square root curve. They both cross or touch the x axis at 2.Choice C) This is false. For example, the value x = 0 is not in the domain of the square root function, but it is part of the domain of the absolute value function.Choice D) This is true. You have the correct answer. There is no y intercept because the square root curve does not touch or cross the y axis.Choice E) This is false. The first part about the square root function having a minimum domain value is true. This is x = 2, which is the smallest x value allowed. However, the part about the other two functions having a minimum range value is false. The arrows on the parabola indicate the curve goes forever downward. There is no smallest y value on the parabola. The same applies for the absolute value graph as well. Since both parts of choice E aren't true, this means the complete statement overall is false.

A studio charges a sitting fee of AED 25 plus AED 7 for each portrait sheet ordered. Write an expression that can be used to find the total cost to have photographs taken. Then find the cost of purchasing twelve portrait sheets.

Answers

Answer:

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
