If c(x)=5/x-2 and d(x)=x+3,. What is the domain of (CD)(x)

Mathematics
1 answer:
valentina_108 [34]3 years ago
6 0

Answer:

  all real numbers except x=2

Step-by-step explanation:

We assume you intend c(x) = 5/(x-2), rather than c(x) = (5/x) -2 as written.

__

The domain of c(x) is real numbers, excluding 2. Multiplying c(x) by d(x) doesn't change that.

The domain of (cd)(x) = c(x)×d(x) = 5(x+3)/(x-2) is "all real numbers except 2".

__

2 is excluded because c(x) is undefined for that value.

stepladder [879]
If 4/5 of the total is 48, the total can be found by dividing it by 4 and multiplying it by 5:
48/4 = 12
12*5 = 60.

Please help me with how to solve this equation by completing the square. The answer should be (2, -6)
OLga [1]

Answer:

(2, -6)

Step-by-step explanation:

5n^2+20n-60

(5n+30)(n-2)

5n + 30 = 0

5n = -30

(5n = -30)/5

n = - 6

n - 2 = 0

n = 2

answer: (2, -6)

Circles M and K are congruent, QR is congrent to LN. Find the length of QR
Novosadov [1.4K]

Given QR is congrent to LN and QR = 4x + 2 and LN = x + 7.

So, QR = LN

Hence, we can set up an equation as following:

4x + 2 = x + 7

4x + 2 - x = x + 7 - x Subtract x from each sides.

3x + 2 = 7 By simplifying.

3x + 2 - 2 = 7 - 2 Subtract 2 from each sides.

3x = 5

\frac{3x}{3} =\frac{5}{3} Divide each sides by 3 to isolate x.

So, x=\frac{5}{3}

Next step is to plug in x=\frac{5}{3} in QR = 4x+2 to get length of QR.

So, QR = 4(\frac{5}{3})+2

=(\frac{20}{3})+\frac{2}{1} Since 2 can be written as 2/1.

By multiplying the second fraction by the common denominator 3.

=(\frac{20}{3})+\frac{2*3}{1*3}

=(\frac{20}{3})+\frac{6}{3} By simplifying the second fraction.

=(\frac{26}{3})

So, QR=\frac{26}{3}
