Well the equation for slope is \frac{ y_{2}- y_{1}  }{ x_{2} - x_{1}  }

number 5
\frac{-1-(-2)}{3-(-2)} = \frac{1}{5}
which means the slope is \frac{1}{5}

What is x in this equation- 3/2x-7=-11
Sunny_sXe [5.5K]

3/2x-7=-11


We move all terms to the left:


3/2x-7-(-11)=0



Domain of the equation: 2x!=0


x!=0/2


x!=0


x∈R



We add all the numbers together, and all the variables


3/2x+4=0


We multiply all the terms by the denominator



4*2x+3=0


Wy multiply elements


8x+3=0


We move all terms containing x to the left, all other terms to the right


8x=-3


x=-3/8


x=-3/8

Find the coordinates of the point (a, b).
Leviafan [203]

Answer:

a = \frac{1}{\sqrt{2} } and b = \frac{\sqrt{2} }{2}

Step-by-step explanation:

As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)

We use trigonometric formulas to find out a and b

  • Sin(45) = opposite side / hypotenuse

<=> Sin(45) = b / 1

<=> b= Sin(45)*1 = \frac{\sqrt{2} }{2}

  • Cos(45) = adjacent side / hypotenuse

<=> Cos(45) = a / 1

<=> a =  Cos(45)*1 = \frac{1}{\sqrt{2} }

So: a = \frac{1}{\sqrt{2} } and b = \frac{\sqrt{2} }{2}
