Answer:

19.65

Step-by-step explanation:

you line 28.9 with 9.25 below it and then you subtract it. take it one column at a time.

28.9

- 9.25

the imaginative zero becomes 10 and then the 9 becomes an 8 so 10-5=5 and 8-2=6

then you subtract 9 from 28 and get 19

Find the solution to the system of equations below. 2y = 2x - 8 2x + y = 5

ladessa [460]

Answer:

The solution to the system of equations is:

(x, y) = (3, -1)

The graph is attached below.

Step-by-step explanation:

Given the system of equations

$2y = 2x - 8$

$2x + y = 5$

Let us solve the system of equations using the elimination method

$\begin{bmatrix}2y=2x-8\\ 2x+y=5\end{bmatrix}$

Arrange equation variables for elimination

$\begin{bmatrix}2y-2x=-8\\ y+2x=5\end{bmatrix}$

Multiply y + 2x = 5 by 2: 2y + 4x = 10

$\begin{bmatrix}2y-2x=-8\\ 2y+4x=10\end{bmatrix}$

subtracting the equations

$2y+4x=10$

$-$

$\underline{2y-2x=-8}$

$6x=18$

solve 6x = 18 for x

$6x=18$

Divide both sides by 6

$\frac{6x}{6}=\frac{18}{6}$

simplify

$x=3$

For 2y - 2x = -8 plug in x = 3

$2y-2\cdot \:3=-8$

$2y-6=-8$

Add 6 to both sides

$2y-6+6=-8+6$

Simplify

$2y=-2$

Divide both sides by 2

$\frac{2y}{2}=\frac{-2}{2}$

Simplify

$y=-1$

Therefore, the solution to the system of equations is:

(x, y) = (3, -1)

The graph is attached below.

Answer:

(look at this equation) y=3x+2

Step-by-step explanation:

1. 2y-6x=4

2. Add -6x over to the other side

3. Subtract 2 from both sides

4. Look and see which points according to the equation that I answered for you.

The hypotenuse and one of the legs of a right triangle form an angle that has a cosine of square root 2 over 2 . What is the mea

ziro4ka [17]

To answer this question, you can use the values of the unit circle to figure out the angle measurement. Since the cosine is the x value of the circle, we can see that at 45°, the x value is √2/2.
So the missing angle should be 45°
