The answer is D because, as decimals, 4 1/3 would be 4.33(a repeating decimal) and 4 3/5 would be 4.6, and 4.4 is between those two numbers. I hope this helps.

Answer:

d. 4.4

Step-by-step explanation:

you can turn your mixed numbers into improper fractions

4 1/3= 13/3 4 3/5=23/5

from her you want common denominators, so multiply the left by 5 and the right by 3

65/15 and 69/15 is what you have now. divide 65 by 15 and your first number is 4.3, divide 69 by 15 and you get 4.6. Therefore 4.4 is the only possible answer

F(x)=3x-1 and g(x)=x+2 find (f+g)

Doss [256]

Answer:

(f+g)(x) = 4x + 1

Step-by-step explanation:

(f+g)(x) = f(x) + g(x) = 3x -1 + x + 2

Combining the like terms:

3x + x - 1 + 2

= 4x + 1

Hence,

(f+g)(x) = 4x + 1

Prove tan(x - (π / 4)) = (sin x – cos x) / (cos x + sin x) by filling in the reasons in the table below.

Mrac [35]

No way to know what reasons you're supposed to choose from...

By definition of tangent,

$\tan\left(x-\dfrac\pi4\right)=\dfrac{\sin\left(x-\frac\pi4\right)}{\cos\left(x-\frac\pi4\right)}$

The angle sum identities give

$\tan\left(x-\dfrac\pi4\right)=\dfrac{\sin x\cos\frac\pi4-\cos x\sin\frac\pi4}{\cos x\cos\frac\pi4+\sin x\sin\frac\pi4}$

$cos\dfrac\pi4=\sin\dfrac\pi4=\dfrac1{\sqrt2}$ , so we can cancel those terms to get

$\tan\left(x-\dfrac\pi4\right)=\dfrac{\sin x-\cos x}{\sin x+\cos x}$

as required.
