Answer:
114.57 .....................
Solving for y, we add 5y to both sides and subtract 4, getting 9x-4=5y. Dividing both sides by 5, we get 9x/5-4/5=y. Since the slope is 9/5 (since 9/5*x=9x/5), we multiply it by -1 and find the reciprocal of it to get -5/9 as the perpendicular slope, so -5x/9+b=y. Plugging 1 in for x and -6 in for y, we get -5*1/9+b=-6 and by adding 5/9 to both sides we get -5-4/9=b , and since in y=mx+b y and x are variables, we end up with y=-5x/9+(-5-4/9) for slope intercept form.
To get it into standard form, we need it in ay+cx=b with a, b, and c being constants. Adding 5x/9 to both sides, we end up with y+5x/9=(-5-4/9) for standard form
First you would convert the decimal into a fraction
1.6= 8/5
8/5-3/8
Then subtract the fractions
49/40
Then you are left with your answer:
49/40

Answer:
Step-by-step explanation:
5,805 divided by 21 would be 276.4.
x 2 + y 2 + a x + b y = c
x2 + y2 − 2x + 6y − 6 = 0
Steps:
x^2 + y^2 - 2x + 6y - 6 = 0
(x - 1)^2 + (y - (-3)^2=4^2
Which means...
Center = (1,-3)
Radius = 4
