Answer:
c. t=±x√2a
Step-by-step explanation:
x^2 + y^2 + 2x - 6y + 1 = 0
x^2 +2x + 1 + y^2 - 6y = 0
x^2 + 2( x × 1) + 1^2 + y^2 - 2(y×3) + 3^2 -3^2 =0
(x+1)^2 + (y-3)^2 = 3^2
comparing with circle equation
(x-a)^2 + (y - b)^2 = r^2
where (a , b) is centre of circle.
so we get center of circle is
(-1, 3)
Answer:
The Answer is $9
Step-by-step explanation:
What i did was multiplied 7 times 6 and that equaled 42. They all used 2 dollar off coupons. You asked what was the price of one movie ticket without the coupon, so i added $2 to 7 and got $9
Answer:
y=7 so all of the y's are 7 but the last one is 4
This equation can be used when comparing ages.
An example to illustrate this:
Assume that adding 6 to 3 times the age of Jack will give us the age of his grandfather.
When translating this into equations, assuming that the age of jack is "a" and the age of his grandfather is "b", we will find that:
b = 6 + 3a
