Write a rule for the transformation of triangle RST. (x,y) --> ( , )

Answer:

25 - 3x = 40            ​x=-5

1/3x - 12 = -3           x=27

Step-by-step explanation:

25-3x=40 -> subtract 25 each side .... -3x=15 -> divide -3 each side...... x= -5

Step-by-step explanation:

If we assume the number of potatoes is proportional to the weight, then we can write the equation ...

  n/10 = 10/3.2

  n = 100/3.2 = 31.25 . . . . . . . multiply by 10

There may be 31 potatoes in a 10-lb bag.

The value of x=2 and y=1.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3x+2y=8

5x+2y=12

Now, solving both using method of Elimination Method

3x - 5x = 8-12

-2x= -4

x = -4/ -2

x= 2

and, 3x+ 2y = 8

3(2) + 2y = 8

6  + 2y = 8

2y = 8-6

2y = 2

y = 2/2

y= 1

Hence, the value of x=2 and y=1.

Answer:

Y is 3.

Step-by-step explanation:

Your welcome : )

Answer:

Step-by-step explanation:

when you want to find x all you have to do is find 6 on the x axis (the horizontal line) and move up until you find the point above or below it.

in this case it is 3 units above the x axis

so y = 3

Answer:

x^2(5x + 7)(5x - 7)

Step-by-step explanation:

Considering you need a negative and a positive to get a negative number, the second and fourth options are wrong. The first option still needs to factor out x^2, which is why x^2(5x + 7)(5x - 7)  is correct.

Answer:

It will take 40 minutes for me to make the 360 wraps that I need.

9x ≥ 360 ⇒ x ≥ 40

Step-by-step explanation:

I have to make at least 360 wraps for a party.

I can make 9 wraps per minute.

So, it will take  minutes for me to make the 360 wraps that I need.

If I work for x minutes to make wraps, then I will be able to make 9x wraps.

So, the inequality that models the given condition is

9x ≥ 360

⇒ x ≥ 40 {Dividing both sides by 9}

Therefore, I need to work at least 40 minutes to reach my goal. (Answer)

Answer: (t,u) -> (t-3, u+8)

Step-by-step explanation: Up is the y value and left is the x value.

In the point ( t,u) t is the x value and u is the y value.

Moving to the left, you subtract the value and moving up you add the value.

The answer would be (t, u) → (-t – 3, u + 8)

Answer:

(-4,-8)

Step-by-step explanation:

The solution to the system of equations is,

⇒ (- 4, - 8)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expressions are,

⇒ y = 1/2x - 6

⇒ x = - 4

Now, We can simplify the expression for y as;

⇒ y = 1/2x - 6

Put x = - 4;

⇒ y = 1/2 × - 4 - 6

⇒y = - 2 - 6

⇒ y = - 8

Thus, The solution to the system of equations is,

⇒ (- 4, - 8)

Answer:

2month and 2 weeks

Step-by-step explanation:

We are told that the first plan has a $50 sign-up

fee and costs $20 per month.

let the number of months be x, and the total cost be y

y=20x+50---------1

The second plan has a $30 sign-up fee and costs $25 per

let the number of months be x, and the total cost be y

y=30x+25---------2

Equate the two equations we have

20x+50=30x+25

solve for x, collect like terms

50-25=30x-20x

25=10x

divide both sides by 10

x= 25/10

x=2.5 months

x= 2month and 2 weeks

Answer:

$16

Step-by-step explanation:

60 + 4 = 64

64 ÷ 4 = 16

CHECK:

16 x 4 = 64

64 - 4 = 60

This is because 65/13 = 5 when using a calculator or long division. There are no fractional or decimal parts to the result 5, so 5 is an integer.

Something like 86/6 = 14.333 approximately showing the result is not an integer. The same applies to choice C and choice D as well.

(3x + 1) (x - 2)

= 3x(x - 2) + 1(x - 2)

= 3x² - 6x + x - 2

= 3x² - 5x - 2
