The answer is c. You distribute the X to the F and G. f(x) + g(x), which is x + 2.
Answer:
Step-by-step explanation:
Standard form follows 2 rules: both x and y go on the same side of the equals sign, and the constant goes on the other side; no fractions allowed.
Getting both x and y on the same side we have
-3x - 2y = 2
We don't have any fractions in there so we're good as far as that goes. Some math books do not like to lead with negatives, so if we multiply the whole equation through by a -1, we get
3x + 2y = -2
which is probably the more "acceptable" answer.
Answer:
The given answer is FALSE
Step-by-step explanation:
![\text{The function is given to be }\tan^{-1}x](https://tex.z-dn.net/?f=%5Ctext%7BThe%20function%20is%20given%20to%20be%20%7D%5Ctan%5E%7B-1%7Dx)
Domain : The domain of a function is the set of values for which the function's value is real and defined.
So, The domain of the given function will be all real numbers
Interval Notation : -∞ < x < +∞
Range : The set of values of the dependent variable for which the function is defined.
The basic arctan function is only defined for :
![(\frac{-\pi}{2},\frac{\pi}{2})](https://tex.z-dn.net/?f=%28%5Cfrac%7B-%5Cpi%7D%7B2%7D%2C%5Cfrac%7B%5Cpi%7D%7B2%7D%29)
So, The range of the given function is :
![\bf (\frac{-\pi}{2},\frac{\pi}{2})](https://tex.z-dn.net/?f=%5Cbf%20%28%5Cfrac%7B-%5Cpi%7D%7B2%7D%2C%5Cfrac%7B%5Cpi%7D%7B2%7D%29)
Therefore, The given answer is FALSE
Answer: A
<u>Step-by-step explanation:</u>
≅ ![\stackrel\frown{YZ}](https://tex.z-dn.net/?f=%5Cstackrel%5Cfrown%7BYZ%7D)
⇒ ∠XOY ≅ ∠ZOY
≅
since they are both a radius
≅
based on reflexive property
∴ ΔXOY ≅ ΔZOY by SAS
So,
≅
by CPCTC
ZY = 10.2 is given
so, XY = 10.2 by substitution property
