Step-by-step explanation:

Answer:

x = 0, y = -7

Step-by-step explanation:

x - 4y = 28

-4x - y = 7

____________

x - 4y = 28

-16x - 4y = 28

____________  _

17x = 0

x = 0

0 - 4y = 28

y = -7

Answer:

(0,-7)

Step-by-step explanation:

x-4y=28      multiply by 4

-4x-y=7       multiply by 1

4x-16y=112

-4x-y=7

cross out the x and add the rest

-17y= 119

divide by -17

y= -7

now you substitute the y in one of the equations.

the reformed equations

we will use the second one

-4x-(-7)=7

two negative becomes a plus

-4x+7=7

now you minus the 7 to both sides

-4x=0

now divide by -4

x=0

(0,-7)

well since it is 130 per month, the first month would be 130, then the second month would double to 260 and etc.

Answer:

24.44%

Step-by-step explanation:

1) Find the difference between 45 and 56 as a number.

2) Divide the result from Step 1 by the starting number 45.

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

The three steps above can be made into a formula. Thus, to find the percent change from 45 to 56, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 45, and Y is the ending number 56 that it changed to. When we enter these numbers into the formula, we get:

((56-45)/45)*100 = 24.44%

Thus, the answer to the question "What is the Percent Change from 45 to 56?" is:

Answer:

29/9 3.2222222 repeating

301/20 15.05 terminating

-53/10 -5.3 terminating

Step-by-step explanation:

multiply the denominator by the whole number then add the numerator. put it over the denominator.

example:

9 x 3 = 27 + 2 = 29

29/9

divide to find decimal

terminating if there is an end, repeating if it’s the same number over and over

Answer:

7

Step-by-step explanation:

450-100=350

350/50=7

7 months

Leanna has been saving for 7 months to have the balance of $450.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as linear equation in one variable.

Let's suppose the Leanna has been saving the money for 'x' months

It means total months = x

Intial balance = $100

Each month she deposit = $50

After x months she will have  = $450 (with initial balance)

We can frame a linear equation in one variable such that:

50x = 450 - 100  (without initial balance)

50x = 350 (divide by 50 on both sides)

x = 7 months

Thus, Leanna has been saving for 7 months to have the balance of $450.

Answer:

4n+2 (B)

Step-by-step explanation:

Answer:

the answer is b

Step-by-step explanation:

because the value of terms are going up by 4 every time, so if you subtract 4 you get 2 and the position would be 0 making 2 the y-intercept and then slope is= rise/run and the equation is rising 4 units for every 1 unit moved, so the slope is 4/1 or 4. plug all of that into the equation and you get 4n + 2

Answer:

[tex]5x^2-5x-6x+6[/tex]

Step-by-step explanation:

[tex]5x^2-11x+6\\5x^2-5x-6x+6[/tex]

we need to factorize it so the X-term expanded should satisfy two conditions

1) +5 times +6 should be +30

2) add or subtract any two numbers which multiply and give -11

so here -5 times -6 gives +30 and -5 added to -6 equals -11

Answer: (x, y) = (10, 10)

Since x = y, replacing y with x in 6x - 3y = 30 we have 6x - 3x = 3x = 30, so x = 30/3 = 10. Then y = x = 10, so the solution is (10, 10).

Answer:

48

Step-by-step explanation:

Vertical angles are congruent

7x - 22 = 4x + 8     {Add 22 to both sides}

         7x = 4x + 8 + 22

        7x = 4x + 30         { subtract 4x from both sides}

7x - 4x = 30

         3x = 30

           x = 30/3

x = 10

4x + 8 = 4*10 + 8

          = 40 + 8

          = 48

7x - 22 = 7*10 - 22

            = 70 - 22

            = 48

Answer:

  no solution

Step-by-step explanation:

We can eliminate parentheses and collect terms.

  5x +3 = 2x +6 +3x -6

  5x +3 = 5x

  3 = 0 . . . . . . . . subtract 5x from both sides

There is no value of x that will make this true. There is no solution.

Answer:

No solution

Step-by-step explanation:Does that make sense to u, You distribute 2 with x and 3 which gets you 2x+6. Combine like terms and you will get 5x on the right side, since the 6's cancel out. 5x+3=5x.

X cancels out and u are left with 3=nothing which makes it no solution
