Answer:

y= 10x-6

Step-by-step explanation:

Linear equation: y=mx+b

You need to isolate the y variable (make sure that it's alone), so to do that you have to:

Subtract 12 on both sides:

2y=20x-12

then, divide both sides by 2:

y=10x-6

Answer: see proof below

Step-by-step explanation:

Use the following Half-Angle Identities: tan (A/2) = (sinA)/(1 + cosA)

cot (A/2) = (sinA)/(1 - cosA)

Use the Pythagorean Identity: cos²A + sin²B = 1

Use Unit Circle to evaluate: cos 45° = sin 45° = $\frac{\sqrt2}{2}$

Proof LHS → RHS

Given: $cot\ (22\frac{1}{2})^o-tan\ (22\frac{1}{2})^o$

Rewrite Fraction: $cot\ (\frac{45}{2})^o-tan\ (\frac{45}{2})^o$

Half-Angle Identity: $\dfrac{sin(45)^o}{1-cos(45)^o}-\dfrac{sin(45)^o}{1+cos(45)^o}$

Substitute: $\dfrac{\frac{\sqrt2}{2}}{1-\frac{\sqrt2}{2}}-\dfrac{\frac{\sqrt2}{2}}{1+\frac{\sqrt2}{2}}$

Simplify: $\dfrac{\frac{\sqrt2}{2}}{\frac{2-\sqrt2}{2}}-\dfrac{\frac{\sqrt2}{2}}{\frac{2+\sqrt2}{2}}$

$=\dfrac{\sqrt2}{2-\sqrt2}-\dfrac{\sqrt2}{2+\sqrt2}$

$=\dfrac{\sqrt2}{2-\sqrt2}\bigg(\dfrac{2+\sqrt2}{2+\sqrt2}\bigg)-\dfrac{\sqrt2}{2+\sqrt2}\bigg(\dfrac{2-\sqrt2}{2-\sqrt2}\bigg)$

$=\dfrac{2\sqrt2+2}{4-2}-\dfrac{2\sqrt2-2}{4-2}$

$=\dfrac{4}{2}$

= 2

LHS = RHS: 2 = 2 $\checkmark$

A 26‘long painting is how many yards long?

Deffense [45]

Hello!

If a painting is 26 feet long, it's 8 and 2/3 yards long.

This is because there is 3 feet in a yard. You would do 26 divided by 3. You would get 8 yards and have 2 feet left. Obviously 2 feet is smaller than a yard, so it'd be 2/3 of a yard. Therefore the answer is 8 and 2/3 yards.

Hope this helped! :)

A rectangle has an area of 54 square inches and a length of 6 in what is the width in inches of the rectangle?

Arada [10]

$\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the Concept of the Areas and Volumes.

We know that, Area of a Rectangle = length * Width.

Since,here Length = 6 inch and Area = 54 square inches,

==> Width = Area / length

==> Width = 54/6

=> Width = 9 inches.

Hence the width of the rectangle is 9 inches.
