If f(x0=3x^-4 and g(x)=x+2 find (f-g)(x)

Mathematics

Yuki888 [10]3 years ago
8 0

So for this, our equation is gonna be(f-g)(x)=3x^{-4}-(x+2)


Firstly, reverse the signs in (x+2) (f-g)(x)=3x^{-4}-x-2


Next, change 3x^-4 to 3/x^4, and your answer will be (f-g)(x)=\frac{3}{x^4}-x-2

Factor completely 4xy − 7x 20y − 35. (x 5)(4y − 7) (x − 5)(4y 7) (x − 5)(4y − 7) (x 5)(4y 7).
yuradex [85]

Answer:

A)

Step-by-step explanation:

Given expression:

To factor the given expression completely.

Solution:

In order to factor the expression, we will factor in pairs.

We will factor the G.C.F of the terms in the pairs.

G.C.F. of  and  can be given as:

Thus, G.C.F. =

G.C.F. of  and  can be given as:

Thus, G.C.F. =

The expression after factoring the G.C.F. pairs is given as:

Taking G.C.F. of the whole expression as  is a common term.

The expression is completely factored.

-12x - 0.4 > 0.2(36.5x + 80) - 55    Remove the brackets.

-12x - 0.4 > 7.3x + 16 - 55               Combine the like terms on the right

-12x - 0.4 > 7.3x - 39                      Add 12x to both sides

- 0.4 > 7.3x + 12x - 39    

- 0.4 > 19.3x - 39                            Add 39 to both sides.

-0.4 + 39 > 19.3x                              Combine like terms on the left

38.6 > 19.3x                                    Divide by 19.3

38.6 / 19.3 > x

2 > x

— 2y – Зу +8 = 8 — 5у – 12
jasenka [17]

Answer:

No Solution.

Step-by-step explanation:

Equality equation:

— 2y – Зу +8 = 8 — 5у – 12  (Given)

-5y + 8 = -4 - 5y (distributive property of equality)

-5y = -12 - 5y (subtraction property of equality)

= -12 (addition property of equality)

when you add 5y on both sides it cancels the 5y out, it's no solution.

Translate the given phrase into an algebraic expression and simplify if possible: the product of -13 and the difference of c
Musya8 [376]

Answer:  -13c+13d

Step-by-step explanation:

For this exercise it is important to remember the following:

1. By definition, the "Product" is the result of a multiplication.

2. The "Difference" is defined as the result of a subtraction.

3. The Distributive property states that:

a(b+c)=ab+ac\\\\a(b-c)=ab-ac

Keeping the above on mind, you know that:

"The difference of c and d" can be represented with the following expression:

c-d

Therefore, "The product of -13 and the difference of c and d" can be represented with this expression:

-13(c-d)

Finally, you must apply the Distributive property in order to simplify the expression. You get:

=-13c+13d
