Answer:x=53/6 and y=-55/6
Step-by-step explanation:
Let the first number x
Second number b y
Sum of the numbers x+y=-1/3
x-y=18
Solve simultaneously
Using elimination method
We get
2y=-55/3
y=-55/6
Substitute for y in equation 1
x+55/6=18
x=18-55/6
x=53/6
Answer:
Equation of function, y = (x-1)²
Step-by-step explanation:
The general formula of a parabola symmetric about x - axis is given by (x-h)²=4a(y-k), where (h,k) is the vertex.
Here (h, k) = (1,0)
So, we have (x-1)²=4a(y-0)
(x-1)²=4ay
One point on the parabola is (0,1) since y intercept is 1.
Substituting
(0-1)²=4 x a x 1
1 = 4 a

Equation of parabola,

Equation of function, y = (x-1)²
Answer:
A
Step-by-step explanation:
Find the common factors between the 2:
2πr + 4πrh
2 (πr+2πrh)
2πr (1 + 2h)
Just multiply the expression by 4.
