Answer:
B. False
Step-by-step explanation:
<u>For f(x) to be a function, only one x-value can be assigned to a y-value. The x-values cannot repeat, which in this case, they do (such as 6 and 12), meaning f(x) is </u><u>not</u><u> a function.</u>
Answer:
100 gm calcium, 30gm carbon and 120gm oxygen
Step-by-step explanation:
10% of a kg is 100gm of calcium, 3% of 1 kg is 30gm of carbon and 12% of a kg is 120gm of oxygen
Answer:
d-5=2s
Step-by-step explanation:
Diego's age d is 5 more than 2 times his sister's age s.
The equation used to represent it is :
d = 2s +5
We need to find the equivalent equation for the above equation.
If we take 5 to LHS of the equation, it will become -5 such that,
d-5=2s
Hence, option (b) is the equivalent equation.
What are you supposed to 'do' with it ?
There's a very simple reason why no 'solution' is possible:
In order to find a unique solution, you need as many equations
as variables. This is one equation in two variables, so it has
infinitely many solutions ... pairs of numbers for 'x' and 'y' that
make the equation a true statement.
Here's one of them: (π/2, 0) .
This would be perpendicular
