Please help 2х -3y =18

siniylev [52]

Answer:

x = 3(6 + y)/2

Step-by-step explanation:

Solving for x

Add 3y to both sides.

2x = 18 + 3y

Divide both sides by 2.

x = 18 + 3y/2

Factor out the common term 3.

x = 3(6 + y)/2

Answer:

$p=36^{\circ}$

Step-by-step explanation:

We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is $90^{\circ}$ .

Because all the angles of a triangle sum to $180^{\circ}$ , we have that $p+54+90=180$ .

We combine like terms on the left side to get $p+144=180$ .

We subtract $144$ on both sides to get $p=36$ .

So, $\boxed{p=36^{\circ}}$ and we're done!

Multiply Conjugates (r+1/4)r-1/4)

Mamont248 [21]

Answer:

$\large\boxed{\left(r+\dfrac{1}{4}\right)\left(r-\dfrac{1}{4}\right)=r^2-\dfrac{1}{16}}$

Step-by-step explanation:

$\text{Use}\ (a+b)(a-b)=a^2-b^2\\\\\left(r+\dfrac{1}{4}\right)\left(r-\dfrac{1}{4}\right)=r^2-\left(\dfrac{1}{4}\right)^2=r^2-\dfrac{1^2}{4^2}=r^2-\dfrac{1}{16}$
