Multiply the first equation by 2 to give
10x + 2y = 20
2x - 2y = 4 Adding to elininate y
12 x = 24
x = 2
Plug x = 2 into 2x - 2y = 4
4 - 2y = 4
y = 0
so the answer is
(2,0)
Answer:
the rate should be 6ml/hr
Step-by-step explanation:
if 100 ml of solution have 50 units each ml has 0.5 units, (50/100)
so in order to get 3 units in one hour the equation would be
number of units = units per mililiter * number of mililiters in an hour
3 = 0.5 * x
x= 3 / 0.5 = 6ml/hr
Answer:
It is not a tautology
Step-by-step explanation:
when all values remain true that is called tautolgy.It would be absurdity because all values are going false
Let's assume that y = ax + b is your regression equation.
Then a represents the slope of the regression line, and b represents the y-intercept (value of y when x = 0).
