The answer is 2 because they are divisible by two
Answer:
a. exponential
b. neither
c. exponential
d. linear
Step-by-step explanation:
b is neither because it is a quadratic function which forms a parabola:)
When the concentration of a solution is expressed in weight percentages, that is just equal to the mass of solute over the mass of the total solution. For a solution weighing 210 grams, 5% of it is salt. That is equal to
210*0.05= 10.5 g salt
The rest of the amount, determined by difference, is the amount of solvent which is water.
water = 210-10.5 = 199.5 g salt
To solve for the new concentration, you add up 15 g to the already existing 10.5 g of salt in the solution. The water, on the other hand, remains constant.
Concentration = (15+10.5)/(210+15) = 0.1133 or 11.33%
Answer:
you.. need to provide a picture
Step-by-step explanation:
Answer:
C)
Step-by-step explanation:
Solution of the equation is given by the intersecting point which is (2 , -1)
Find the equation of the line:
(0,4) ; (2 , -1)

m = -5/2 ; (0 , 4)
Equation: y - y1 =m(x -x1)
