In rectangular form, we have the coordinates 
How the quadratic formula works:
For any quadratic equation ax² + bx + c = 0, the solution is

.
In the case of our equation 7x² - x = 7, first we need to subtract 7 from each side so that we have 0 on the right.
7x² - x - 7 = 0
Identify the values of a, b, and c.
a = 7, b = -1, and c = -7.
Plug these into our quadratic formula and solve.

There are two values for x: (1+√197)/14 and (1-√197)/14.
The approximate values for these are 1.073976 and -0.931119.
Ok so it would be 3/4 times 20
And you would get 15
I would draw a circle that adds up to 100
To do this multiply the 20 five times to get 100
Then multiply the 15 by the same number (5) to get 75
Draw a circle and shade in 75% of it and that is your answer
The answer would be -27 but since you aren't using negatives, A trick I use is cross the line change the sign. So it would be 1/27 I believe
Answer:
y = 1.5x + 4
Step-by-step explanation:
Slope = (y2-y2)/(x2-x1)
= (1-4)/(-2-0) = -3/-2 = 3/2
y = (3/2)x + c
When x=0, y=4 (y-intercept is 4)
y = (3/2)x + 4
y = 1.5x + 4
