You have to start by converting the equation to slope intercept form, or $y=mx+b$ , where m represents the slope, and b represents the y-intercept. Start by subtracting 4x on both sides in order to move it to the other side of the equation. This gives us $3y=12-4x$ . Switch around 12 and -4x to conform to the formula; $3y=-4x+12$ . Finally, divide by 3 to isolate y; $y=-\frac{4}{3}x+4$ . This is the final equation, and it tells us two things, firstly that the slope is negative 4/3, which means that for every 4 units the line goes up, it goes left 3 units, and for every 4 units the line goes down, it goes right 3 units. The y-intercept is where the line intersects when x = 0. 4 is the y-intercept, as it intersects the line at (0, 4). You can then graph it on an online calculator or graph paper. For this example I used an online calculator called 'Desmos'.

Hello, we know that for a and b real numbers

$a^2-b^2=(a-b)(a+b)$

So,

$(2a-b)^2-(a-2b)^2=(2a-b-a+2b)(2a-b+a-2b)\\\\=(a+b)(3a-3b)\\\\\boxed{=3(a+b)(a-b)}$

Thank you.

Evaluate each expression |31|-|-1|

Alenkasestr [34]

That would be evaluated to 31+1 because you have to keep change flip. Keep the 31, change the symbol to addition, then flip the negative 1 to a positive number.

Trigonometry, I don’t know how to find x.

Verizon [17]

Answer:

Step-by-step explanation:

I still suspect that Angle A is 30° and Angle B is 60°. Otherwise the labels do not fit the illustration.

If Angle A is 60°, as you insist, then the solution (the length of x) is as follows:

opp side x

tan 60° = √3 = ---------------- = -----

adj side 7

Then:

√3 x

----------- = -----

1 7

Thru cross-multiplication we see that x = 7√3

Multiply both sides by 7, which produces:

7√3 = x
