A) \frac{2 \frac{1}{4}}{ \frac{1}{2}}
b)\frac{1}{2} • 2 = 1

Need help with this :(
emmainna [20.7K]

Answer:

B.    m = \frac{3}{2}, y-int = 3

Step-by-step explanation:

To find the slope of the line, we need to plot two points

(2, 6) (-2, 0)

m = slope

Then use the Slope-Formula to Solve for the slope

m = \frac{y2-y1}{x2-x1}        

m = \frac{0-6}{-2-2}

m = \frac{-6}{-4}

m = \frac{6}{4}

m = \frac{3}{2}

The Slope is \frac{3}{2}

The y-intercept is 3 because the line is going 3 units upwards on y axis!

Equation: y = 3/2x + 3

Slope: 3/2

y-intercept: 3

R2+2r-33=0 solve by completing the square
-BARSIC- [3]
R^2+2r-33=0  move constant to other side by adding 33 to both sides

r^2+2r=33   halve the linear coefficient, square it and add to both sides, in this case it is just one

r^2+2r+1=34  now the left side is a perfect square...

(r+1)^2=34  take the square root of both sides...

r+1=34^(1/2)  subtract 1 from both sides

r=-1+34^(1/2) and -1-34^(1/2)

An imaginary number has which of the following as a definition?
lyudmila [28]
Her is the definition of an imaginary number An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. Zero is considered to be both real and imaginary.
