Mathematics

Jet001 [13]3 years ago

Answer:

-\frac34 -\frac14 i

Step-by-step explanation:

Let's start with distributing: \frac1{4i}-\frac{3i}{4i} Simplify i with i in the second term, and rearrange.-\frac34 +\frac1{4i}. Since i in the denominator looks ugly, let's multiply top and bottom by i. -\frac34 +\frac i{4i^2} = -\frac34 +\frac i{4(-1)} =-\frac34 -\frac14 i. The middle passage is based on the fact that, by definition, i^2=-1

stepan [7]

Answer:

y= -2/7x-7

Step-by-step explanation:

slope intercept form is just a fancy way of saying y=mx+b

x being your input, y your output, m your slope, and b your y intercept

you can use the slope to determine your equation will look something like: y=-2/7x+b. To find your y-intercept all you do is determine how much the point will increase or decrease so it is equal to (0, y). In this case it will increase by 14 on the x's (so x is equal to 0) and 14*-2/7. When you have determined your y-int and slope you can then plug them into the equation instead of the variables.
