Answer:
(2, - 2 )
Step-by-step explanation:
y = - 3 + 
x → (1)
3x + 2y = 2 → (2)
Substitute y = - 3 + x into (2)
3x + 2(- 3 + x) = 2 ← distribute parenthesis and simplify left side
3x - 6 + x = 2
4x - 6 = 2 ( add 6 to both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Substitute x = 2 into (1)
y = - 3 + (2) = - 3 + 1 = - 2
solution is (2, - 2 )
Set up multiplication/division of ratios to cancel out units you don't need for the final answer and introduce those that you do.
We have m/s and we want m/min so
(100m/s)(60s/min)=6000m/min
It will be C cause you divid 15 and 6
8.876 to the nearest whole number
8.876 can be rounded to 9 because if we have a number greater than 5 we round to next number i.e is 9 but if we have a number smaller than 5 then we round to the previous number that is 8.
So your answer is 9
