We can solve the system of equations to check the number of system of the solutions.
y=-6x+2 ...(1)
-12x-2y=-4 ...(2)
Substitute -6x+2 for y in equation (2). So,
-12x-2(-6x+2)=-4
-12x+12x-4=-4 (By distribution property).
-4=-4 (-12x and +12x has been cancel out).
Notice x has vanish from the above equation and we are left with -4=-4 which is correct.
So, the system has infinte number of solutions.
Answer:
D: Infinite number of solutions
Step-by-step explanation:
I got it right on Edge
Answer:
24-6x
Step-by-step explanation:
To distribute, you multiply the number outside the parenthesis by each number inside, keeping in mind the signs.
So, 6(4-x) = 6(4) - 6(x) = 24-6x
Answer:
6(4) - 6(x)
Step-by-step explanation:
You just separate it so you can divide each separately then subtract the product of both

The solution is
The number of vanilla cone she christina's sold after 20 day is 138.
Christina's ice cream parlor sold 60 vanilla cones on the first day of summer.
If the goal is to increase the number of vanilla cones sold each day by 4
Arithmetic progression is the series of number that have common difference between adjacent numbers.
Christina sold 60 vanilla cone at her first day. a=60
now each day is sells increase by 4 cones
so we common difference D = 4
The progression can be given as
S = a + (n-1)D
for 20th day = 60+(20-1)4
= 138
Thus the required number of vanilla cone she christina's sold after 20 day is 138.
