Systems of linear equations can only have 0, 1, or an infinite number of solutions. The two lines can't intersect twice, so the correct answer is that the system has one solution.

Answer: The correct answer is D
Step-by-step explanation: If you were to scale this up to the actual size, the planets would be so close that each planet would collide with each other because the gravity would interfere to much. If this were accurate, you and me both would not be alive right now. We would be squished to bits by the other planets.

Jack does not have enough money to buy a box of crayons
Answer:
b= -3
x= -2
x= -7
n = -6
Step-by-step explanation:
3b+7-1=-3
3b = -3 -7 +1
3b = -10+1
3b= -9
b = -9/3
b= -3
3x+1-6x=7
-3x = 7-1
-3x= 6
x= -6/3
x= -2
312=-6(7x-3)
312 = -6*7x +6*3
312= -42x +18
312-18= -42x
294 = -42x
x= -294/42
x= -7
-4(4n-8)=128
-4*4n +4*8 =128
-16n +32 = 128
-16n= 128-32
-16n = 96
n=-96/16
n = -6
