Set the number as x
x/5=1.21
Multiply by 5 on each side to cancel the 5 in the denominator.
x=6.05
Check your answer:
6.05/5=1.21
1.21=1.21
Answer:
42 degrees, and 48 degrees
Step-by-step explanation:
set up an equation to find x, the first angle measure
(x+6)+x=90
then simplify:
2x+6=90
2x=84
x=42
So, the first angle measure is 42, now to find the second angle measure, add 6 to 42, and you will get 48.
Hello,
First, you must understand that
(f-g)(x) means f(x)-g(x) it is the difference of two functions :
f(x)=2x+4 and g(x)=3x-7
f(5)=2*5+4=10+4=14
g(5)=3*5-7=15-7=8
So, (f-g)(5)= f(5)-g(5)=14-8<u>=6</u>
Answer A: none of the choices are correct.
An other way to do it:
(f-g)(x)=f(x)-g(x)=2x+4-(3x-7)= 2x-3x+4+7=-x+11
if x= 5 then (f-g)(5)=-5+11<u>=6</u>
Suppose we have a generic polynomial of the form:
![ax ^ 2 + bx + c ](https://tex.z-dn.net/?f=ax%20%5E%202%20%2B%20bx%20%2B%20c%0A)
To know how many roots the polynomial can have, the first thing you should do is observe the term of greatest exponent.
For this case, the term of greatest exponent is 2.
Therefore, the polynomial has 2 roots.
Answer:
You must observe the term of the polynomial with greater exponent.
Answer:
![f^{-1}(x)=y/3-1/9](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3Dy%2F3-1%2F9)
Step-by-step explanation:
![f(x)=3x-2/6](https://tex.z-dn.net/?f=f%28x%29%3D3x-2%2F6)
![f^{-1}(x)=x/3-1/9](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3Dx%2F3-1%2F9)
if ![f(x)=(3x-2)/6](https://tex.z-dn.net/?f=f%28x%29%3D%283x-2%29%2F6)
answer:![f^{-1}(x)=(6x+2)/3](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%286x%2B2%29%2F3)
