a² - b² = (a - b)(a + b)

Thus

x² - 100

Use the unit circle to find all values of thetabetween 0 and 2Ï€ for which sin(theta)=sqrt 3/2
ElenaW [278]
Sin(theta)=√3/2, 0≤theta≤360
In a unit circle, sin is y/r, r is always positive, y is positive in the first and second quadrant only. 
sin60=√3/2, sin120=√3/2
so theta is 60 or 120

OKay, i need help asap pls. The ratio__ is equivalent to 12/36. The ratio__is not equivalent to 12/36.
EleoNora [17]

The ratio of 1:3 is equivalent to 12/36. The ratio 3 / 4 is not equivalent to 12/36.

Given that,
The ratio__ is equivalent to 12/36. The ratio__is not equivalent to 12/36.
Blank statement to be filled from the options.

<h3>What is the Ratio?</h3>

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
12 / 36 = 1 / 3
and
12 / 36 ≠ 3 / 4

Thus,  the ratio of 1:3 is equivalent to 12/36. The ratio 3 / 4 is not equivalent to 12/36.

Y= 2/3x -1 y= -x + 4
blondinia [14]

Answer:

x=3\\y=1

Step-by-step explanation:

To solve the system of equations you must apply the proccedure shown below:

- Make both equations equal to each other.

- Solve for x.

Then:

\frac{2}{3}x-1=-x+4\\\\\frac{2}{3}x+x=4+1\\\\\frac{5}{3}x=5\\5x=5*3\\x=\frac{15}{5}\\\\x=3

- Substitute the value of x obtained into any on the original equations to find y:

y=-3+4\\y=1
