Answer:

This is called the multiplicative identity property.

Step-by-step explanation:

This property states that any number multiplied by 1 is itself. In this example, 10 multiplied by 1 still equals 10. This therefore, shows that property.

Solve the system below by substitution.

Olegator [25]

Answer:

$(-4, -1)$

Step-by-step explanation:

$6x-y=-23$

Add y to both sides:

$6x-y+y=-23+y\\6x=-23+y$

Divide both sides by 6:

$\frac{6x}{6}=-\frac{23}{6}+\frac{y}{6}\\x=\frac{-23+y}{6}$

Substitute this into the second equation given:

$2*\frac{-23+y}{6}+5y=-13$

$\frac{-23+16y}{3}=-13$

Multiply both sides by 3:

$-23+16y=-39$

Add 23 to both sides:

$-23+16y+23=-39+23\\16y=-16$

Divide both sides by 16:

$\frac{16y}{16}=\frac{-16}{16}\\y=-1$

We know that $x=\frac{-23+y}{6}$ .

Thus, $x=\frac{-23-1}{6}$

$x=-4$

$(x, y) = (-4, -1)$

What is y={\dfrac{4}{5}}x+2y= 5 4 x+2y, equals, start fraction, 4, divided by, 5, end fraction, x, plus, 2 written in standard

Alex73 [517]

Answer:

$5y-4x=10$

Step-by-step explanation:

We have been given an equation $y=\frac{4}{5}x+2$ . We are asked to write our given equation in standard form.

We know that standard form of an equation is in form $Ax+By=C$ , where A, B and C are constants.

First of all, we will bring x term to left of the equation as:

$y-\frac{4}{5}x=\frac{4}{5}x-\frac{4}{5}x+2$

$y-\frac{4}{5}x=2$

Now, we will multiply both sides of equation by 5 as:

$y\cdot 5-\frac{4}{5}x\cdot 5=2\cdot 5$

$5y-4x=10$

Therefore, our equation in standard form would be $5y-4x=10$ .

PLEASE PLEASE PLEASE!!!! I NEED HELP

BartSMP [9]

Answer:

Step-by-step explanation:

y = 7x + 13

y = 3x + 49

================

We can solve this in either of two ways: Mathematically and graphically.

Set the equations equal to each other (after all, y does equal y).

7x + 13 = 3x + 49

4x = 36

x = 9

Then use x = 9 to solve for y:

y = 7x + 13

y = 7(9) + 13

x = 76

<h2><u>Graph</u></h2>

Plot the two equations. I use Desmos - its online and free. The intersection of the two lines reveals to answer: (9,76). See the attachment.
