Answer:
no idea too hard but try math way
Step-by-step explanation:
Answer:
infinitely many solutions
Step-by-step explanation:
Given the simultaneous equation
4x=10+4y... 1
2x-2y=15 .... 2
_____________
4x-4y = 10 * 1
2x-2y = 15 * 2
__________--
4x-4y = 10
4x-4y = 30
Add both equation
8x - 8y = 10+30
8x-8y = 40
Divide though by 8
x-y = 5
x = 5 + y
Since the result gave 1 equation and 2 unknowns, then we will let x =k
k = 5 + y
y = k -5
k can be any integer
(x,y) = (k, k-5)
This show that the equation has infinitely many solutions
Answer:
Circle A= 
Circle B =
Step-by-step explanation:
Circumference of a circle =
Since you are given the radius, you put it in place of r
Circle A = 
Circle B= 
A prime number only has the factors: 1 and itself.
1057 in this case a composite number because it has factors of: 1,7,151,1057
