If g(x) = 2x + 3 and f(x) = x<br><br>2 − 49x, find all solutions of the equation f(g(x)) = 0.
sdas [7]
Basically you just have to plug in g(x) wherever you see an x in the equation f(x) since x is f(x) you just substitute it . So f(g(x))=2x+3

You then just have to solve for 0

0=2x+3
Subtract 3 from both sides
-3=2x
Divide by 2
X=-3/2

How do u do 389.2÷28 in 5 grade standard algorithm show work
Mashutka [201]

Answer:

  see attached

Step-by-step explanation:

Each digit of the quotient is aligned with the least significant digit of the current dividend. The "current dividend" is that portion of the remaining dividend that is at least 1 and less than 10 times the divisor. The product of the quotient digit and the divisor is subtracted from the "current dividend" to get the remaining dividend.

__

For many folks, the hardest part of this algorithm is determining the appropriate quotient digit, and multiplying that by the divisor. Some teachers teach that you start this process by making a list of the multiples of the divisor:

N . . . 28N

1       28

2      56

3      84

4      112

...

This process can be aided by your number sense.

2N is simply N added to itself.

3N is N+2N.

4N is double 2N

5N is half of 10N.

You can proceed to build the table by adding 28 to each previous value, or by recognizing doubles and halves and other sums.
