Answer:
The slope decreases and the y-intercept decreases.
Explanation:
Red is original, blue is when y is doubled.
Length of the diameter = sqrt ( (-12- (-8)^2) +(2-0)^2) )
= sqrt (16 + 4) = sqrt20
so radius = sqrt 20 / 2 = sqrt5
so r^2 = 5
Center of the circle = coordinates of the midpoint of the diameter =
-8-12/2 , 2-0 / 2 = (-10, 1)
(x - a)^2 + (y - b)^2 = r^2 is general form of a circle so here the circle is:_
(x + 10)^2 + (y - 1)^2 = 5 Answer
Its B
Ok so a triangle is equal to 180 degrees!!!
So with that info u can make a crazy little equation
180=70+68+47+x
Ok then you add 70,68 and 47
180=185+x
Ok now u have to subtract 185 on both sides
And get the answer -5=x or x=-5 (same thing)
Answer: 6247.5
Step-by-step explanation:
85% x 105000 = 89250
70 x 89.25 = 6247.5
Step-by-step explanation:
6. 7x + 7y = -11
7. -1x + 8y = 12
8. 9x + 11y = -7
