The way to determine the number of solutions is to complete the problem in multiple different ways.
Plug in the first equation into the he second equation
3x-(2x+7)=-9
3x-2x-7=-9
x-7=-9
x=-2
plug in x=-2 into the first equation
y=2(-2)+7
y=-4+7
y=3
answer: (-2,3)
Answer
The correct answer is B
Step-by-step explanation:
It is B because squares don't intersect so it cant be a
They are always congruent and equal so not c or d it has to be B
1/8*3/4
multiply the numerators together
1*3=3
multiply the denominators together
8*4=32
answer:
3/32
Answer:
PV/nR = T
Step-by-step explanation:
PV = nRT
Divide each side by nR
PV/nR = nRT/ nR
PV/nR = T
