A linear equation has maximum power of a variable(variables) 1.

In order to find the linear equations we need to check the equations with variable with power one.

Also the variable should be in numerator only.

Let us check option one by one:

a-y=√x + 1 we have a radical on x.

Therefore, it's not a linear equation.

b-y=1/x

We have x in the denominator of 1.

Therefore, it's not a linear equation.

c-y=x^2 +4

We have power 2 of x. Therefore, it's not a linear equation.

d-y = -2/3x + 4/3.

We have x and y powers only 1.

Therefore, it's the only linear equation.

<h3>Therefore, correct option is D option. d-y = -2/3x + 4/3</h3>

How do i find x and y?

Stells [14]

Answer:

x=90

y=67

Step-by-step explanation:

as the line that bisects the vertical angle of isosceles triangle perpendicularly bisects the base

so x=90

and sum of all sides of triangle is 180 so

90+23+y=180

therefore,y=67

Given: cosθ= -4/5 , sin x = -12/13 , θ is in the third quadrant, and x is in the fourth quadrant; evaluate tan 1/2 θ

Answer:

Step-by-step explanation:

If you're looking for what the half angle of the tangent of theta is, I'm a bit confused as to why you think the angle in the 4th quadrant, x, is relevant. But maybe you don't know it isn't and it's a "trick" to throw you off. Hmm...

Anyways, the half angle identity for tangent is

$tan(\frac{\theta}{2})=\frac{sin\theta}{1+cos\theta}$

There are actually 3 identities for the tangent of a half angle, but this one works just as well as either of the others do, so I'm going with this one.

If theta is in QIII, the value of -4 goes along the x axis and the hypotenuse is 5. That makes the missing side, by Pythagorean's Theorem, -3. Filling in our formula:

$tan(\frac{\theta}{2})=\frac{-\frac{3}{5} }{1+(-\frac{4}{5}) }$ which simplifies a bit to

$tan(\frac{\theta}{2})=\frac{-\frac{3}{5} }{\frac{5}{5} -\frac{4}{5} }$ and a bit more to

$tan(\frac{\theta}{2})=\frac{-\frac{3}{5} }{\frac{1}{5} }$

Bring up the lower fraction and flip it to divide to get

$tan(\frac{\theta}{2})=-\frac{3}{5}*\frac{5}{1}$ which of course simplifies to

-3. Choice A.
