Answer:
12.50+2x=y
Step-by-step explanation:
y is the total 12.50 us base and x would be how many times you muliply the 2
Given:
The function is
To find:
The range value if the domain value is 1.75.
Solution:
Domain is the set of input values and range is the set of output values.
Here, range value if the domain value is 1.75. It means the value of function f(x) at x=1.75.
Substitute x=1.75 in the given function.
Therefore, the required range value is 4.5.
We can solve for x in by substituting 'y=15-5x' from the second one into the first equation, because in the second equation, y has no coefficient, which will make it easier to substitute.
Answer:
d + q = 50
0.10d + 0.25q = 7.30
Step-by-step explanation:
Since all of the 50 coins are dimes and quarters, we can write the equation:
d + q = 50, where d is the number of dimes and q is the number of quarters
Now, we know that dimes are 10 cents, or $0.10 and quarters are 25 cents, or $0.25. So, if we multiply 0.10 by d, we get the total value of the dimes, and if we multiply 0.25 by q, we get the total value of the quarters. The total value of all dimes and quarters is 7.30, so we have the equation:
0.10d + 0.25q = 7.30
Thus, the system is:
d + q = 50
0.10d + 0.25q = 7.30
