solve 4x+y=24 and y=-4x+24 using substitution​

Answers

Answer 1

Answer:

no solutions

Step-by-step explanation:

[tex]4x + y = 24 - - - (a) \\ y = - 4x + 24 - - - (b)[/tex]

substitute for y in (a) with (b):

[tex]4x + ( - 4x + 24) = 24 \\ 0x = 0[/tex]

Answer 2

Answer:

infinite solutions

Step-by-step explanation:

substitute y in the first equation

4x+(-4x+24)=24

4x and -4x cancel out

24/24=1

or solve for x, you should also get 1

What is simple interest?

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Given that:

Principal=P=$225000

Rate of interest=R=3%

Time=10 year

By the use of formula:

[tex]I=\frac{PRT}{100}[/tex]

[tex]I=\frac{225000*3*10}{100} \\\\I=22500*3\\\\I=67500[/tex]

So, the value of the home after the tenth year is 67500.

Using the slope formula, find the slope of the line through the given points. (4. - 2) and ( - 2, - 2)​

Answers

Answer:

- 0/6

Step-by-step explanation:

*I’m pretty sure you meant to type “(4, -2)” instead of “(4. -2)” Anyways…*

m = slope

m = change in y/change in x

m = y2 - y1/x2 - x1

Points: (4, -2) and (-2, -2)

m = -2 - -2/-2 - 4

m = 0/-6

The slope is - 0/6

Hi! I'm happy to help!

To solve this problem, we have to find the slope, which is rise over run, or how much the line rises and how far forward the line goes.

We find the slope using this formula (slope formula)

m(slope)=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

This refers to the second y point minus the first y point, divided by the second x point minus the first x point. Y refers to the y axis, so that is the rise, because it is the difference of height in the line. X refers to the x axis, so that is the run, because it is the difference in how far it travels forward.

Our second y point is -2, our first y point is also -2. Our second x point is -2, and our first y point is 4. Let's plug in our values.

[tex]\frac{-2-(-2)}{-2-4}[/tex]

Let's simplify this so there isn't a double negative.

[tex]\frac{-2+2}{-2-4}[/tex]

Now, let's solve

[tex]\frac{0}{-6}[/tex]

0 divided by -6, is still 0, so there is no slope or the slope is 0. This means that the line is horizontal and the y coordinate doesn't change.

I hope this was helpful, keep learning! :D

Step-by-step explanation:

(7×2)⁶

when we put a number to the power of something, we need to include the whole number. bit just a part of it.

so, it must be 7⁶×2⁶

just think about the simple example 6², which we could write as (2×3)².

would it be sufficient to e.g. square only one of the factors ?

6² = 36

but e.g. 2×3² = 18. so, that's really not it.

or add the two factors and then square them ?

2+3 = 5. 5² = 25. so, that's not it either.

or multiply the exponent in ?

2×3×2 = 12. so that's not it either.

no, it truly is you need to do the operation to all parts.

2²×3² = 4×9 = 36. yes, that fits.

therefore, B is the right answer.

Option B is correct

Step-by-step explanation:

Let the number be x

2x = 85 - 1

2x = 84

x = 84/2 = 42

I can't so please help me

Answer:

Step-by-step explanation:

One

2x + 3 = 8x - 5                Add 5 to both sides

2x + 3 + 5 = 8x               Combine

2x + 8 = 8x                      Subtract 2x from both sides.

8 = 8x - 2x                       Combine

8 = 6x                              Divide by 6

x = 8/6

x = 8.333

Two

3x + 2 = 4                       Subtract 2 from both sides

3x = 4 - 2

3x = 2                             Divide by 3

x = 2/3

2y + 6 = 5                     Subtract 6 from both sides

2y = 5 - 6

2y = -1                          Divide by 2

y = - 1/2

x + y = 2/3 - 1/2

x + y = 4/6 - 3/6

x + y = 1/6

Suppose a right triangle has a
hypotenuse length of 12. If one of
the legs has length 5, what would
the length of the last leg be?

Answers

Answer:

See the last two lines below. I don't know which one you want.

Step-by-step explanation:

hypotenuse = 12

One leg        = 5

other leg =      x            Substitute into a^2 + b^2 = c^2

x ^2 + 5^2 = 12^2

x^2 + 25 = 144              Subtract 25 from both sides

x^2 = 144 - 25              Combine

x^2 = 119                      Take the square root of both sides

x = sqrt(119)

x = 10.91

A fine jewelry store leased a space at the mall with a base rent of $1,800 a month, plus 4% of all sales over $200,000. If the gross sales were $325,000, what was the total amount of rent paid by Heinz Fine Jewelry at the end of the year?

Answers

Answer:

So, first, we have to establish how much the base rent ends up costing. So to find that, we do 1,800x12=21,600. So the base rent is $21,600. Then, we add the 4% of sales which is 125,000x0.04=5,000. So, we add $21,600 with $5,000 and we get a final answer of $26,600 owed at the end of the year :)
