HELP PLEASE AND THANK YOU?!!!!!!!

Answer: y = 2   x = -2

Step-by-step explanation:

-x + y = 4

x + 3y = 4

Since x and -x are opposite, we can use the system of elimination

To do that, we add the first equation and the second equation together

-x + y = 4

      +

x + 3y = 4

      ↓

4y = 8

Now we solve for y

4y = 8

Divide both sides by 4

y = 2

Since we now know y, we can solve for x by substituting y for 2 in one of the equations.

x + 3y = 4

Substitute y for 2

x + 3 (2) = 4

x + 6 = 4

Subtract 6 from both sides

x = -2

Hope I helped! And sorry if I repeated somethings.

Answer:

$91,620

Step-by-step explanation:

1.8% = $54

$3000 + $54 = $3054

Answer:

Step-by-step explanation:

first lets put this in standard form to make it easier

[tex]7x^{3}[/tex] - [tex]5x^{2}[/tex] - 4x + 10

this form is the standard form (exponents go from greatest to least)

The degree in this polynomial is the highest exponent

So the degree is 3

There are 4 terms in this equation

7x^3

-5x^2

-4x

and 10

hope this helps <3

X is the amount of hours. Since they are charging 15 per hour you would have to multiply how many hours (x) by 15. Then add 40. And y equals the total amount pls mark brainliest

Answer:

(5, - 2)

Step-by-step explanation:

2x+y>3

x-y>1

2x + y > 3 - - - - (1)

x - y > 1 - - - (2)

Using trial and error method :

Using :

(5,-2)

2x + y > 3

2(5) + (-2) > 3

10 - 2 > 3

8 > 3 (true)

x - y > 1

5 - (-2) >1

5 + 2 > 1

7 > 1 (True)

For 0,5

2x + y > 3

2(0) + (5) > 3

0 + 5 > 3

5 > 3 (true)

x - y > 1

0 - (5) >1

-5 > 1

--5 > 1 (false)

Also, all other options do not hold true for bitb inequality statements, hence answer is (5, - 2)

Step-by-step explanation:

if you look at the congruency marks you can see that ∡F ≅ ∡A and we know that ∡N ≅ ∡N

markings also show us that sides UF ≅ MA

therefore, we know two angles and one side for each triangle

Answer:

[tex] \frac{39}{y} = \frac{3}{2} \\ y = \frac{39 \times 2}{3} \\ \boxed{y = 26}[/tex]

Answer:

He should play for 12 days

Step-by-step explanation:

Answer:

The solution to the system of linear equations is:

(x, y) = (-2, 8)

Hence, y - 2x = 12 and x - 2y = -18  has the ordered pair (-2,8) as its solution. Thus, option A is correct.

Step-by-step explanation:

Checking the first system of equations

y - 2x = 12

x - 2y = -18

solving the first system of equations

[tex]\begin{bmatrix}y-2x=12\\ x-2y=-18\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}y-2x=12\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y-4x=24[/tex]

[tex]\begin{bmatrix}2y-4x=24\\ -2y+x=-18\end{bmatrix}[/tex]

adding the equations

[tex]-2y+x=-18[/tex]

[tex]+[/tex]

[tex]\underline{2y-4x=24}[/tex]

[tex]-3x=6[/tex]

[tex]\begin{bmatrix}2y-4x=24\\ -3x=6\end{bmatrix}[/tex]

solving -3x=6 for x

[tex]-3x=6[/tex]

Divide both sides by -3

[tex]\frac{-3x}{-3}=\frac{6}{-3}[/tex]

Simplify

[tex]x=-2[/tex]

[tex]\mathrm{For\:}2y-4x=24\mathrm{\:plug\:in\:}x=-2[/tex]

[tex]2y-4\left(-2\right)=24[/tex]

[tex]2y+8=24[/tex]

Subtract 8 from both sides

[tex]2y+8-8=24-8[/tex]

Simplify

[tex]2y=16[/tex]

Divide both sides by 2

[tex]\frac{2y}{2}=\frac{16}{2}[/tex]

Simplify

[tex]y=8[/tex]

Therefore, the solution to the system of linear equations is:

(x, y) = (-2, 8)

Hence, y - 2x = 12 and x - 2y = -18  has the ordered pair (-2,8) as its solution. Thus, option A is correct.

Answer:

Step-by-step explanation:  3root5x^2 + 25x - 10root5 = 0

3xroot5 + 25x - 10root5 = 0      [ root x^2 = x]

28x root5 = 10 root5         [ -10root5 turns to 10 root5 when transferred to RHS]

28x root 5/root5 =10

28x=10

x = 10/28

x = 0.35

Answer:

i think its D

Step-by-step explanation:

The amount she wants to donate is 593, and she has 418 already so subtract that from 593 to get 175, and divide that 175 by 12.50 to get 14 days, and the solid circle means greater than or equal to 14, so it should be D.
