Help me solve this equation. Find f(x)-g(x)

Mathematics
1 answer:
mojhsa [17]3 years ago
8 0

Answer:

- 2x³

Step-by-step explanation:

f(x) - g(x)

= x^{\frac{1}{2} } - x - (2x³ - x^{\frac{1}{2} } - x) ← distribute parenthesis by - 1

= x^{\frac{1}{2} } - x - 2x³ + x^{\frac{1}{2} } + x ← collect like terms )

= - 2x³

Find the solution of the system of equations.<br><br> x-y=-3<br>-8x+y=45
mezya [45]

Answer:

x = 17, y = 28

Step-by-step explanation:

1. Isolate for x in "x - y = -3, -8":

x - y+y = -3, -8+y

x = -11 + y

2. Substitute "x = -11 + y" in for x in the second expression:

-11 + y + y = 45

3. Simplify:

-11 + 2y = 45

4. Isolate y:

-11+11 +2y = 45+11

2y = 56

\frac{2y}{2} = \frac{56}{2}

y = 28

5. Substitute the new y-value into the first equation:

x = -11 + 28

x = 17

hope this helps!

How can you tell when a pattern shows counting on by tens?
velikii [3]
<span><u><em>Answer:</em></u>
The difference between successive terms is 10

<u><em>Explanation:</em></u>
To know the factor by which a certain pattern is increasing/decreasing, you need to subtract its successive terms.

If the subtraction gives you 10, this means that the pattern is increasing by 10

<u>Examples:</u>
<u>10, 20, 30, 40, 50, .....</u>
20 - 10 = 10
30 - 20 = 10
40 - 30 = 10
50 - 40 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, this pattern is increasing by 10

<u>37, 47, 57 , .....</u>
47 - 37 = 10
57 - 47 = 10
The difference between each two successive terms is 10. This means that each time we add 10 to the number we have in order to get the next one.
Therefore, the pattern is increasing by 10

Hope this helps :)</span>
