B for sure remember PEMDAS
The given function is:
The statement A is true. Substituting x = 1 in given expression we get 0. So, (1,0) is the x-intercept of the function.
The statement B is false. There is no y-intercept of the function.
The statement C is false. The base of log is less than 1, so it will be a decreasing function.
The statement D is true.
The statement E if true. Range of the log function is set of all Real numbers.
The statement F is true. The given log function is defined for values of x greater than 0.
So the correct options are A, D, E and F
Answer:
92in^2
Step-by-step explanation:
Find the length of the bottom right triangle.
Use Pythgoras theorem
You will get 8
(1/2)(6)(2)(2)= 12
12+(10)(8)=92
Answer: y=-1x+5
Step-by-step explanation:
1. Use slope-intercept formula (y = mx + b) to find the slope which is represented by the variable 'b'.
m = ∆y / ∆x
m = -1 / 1
m = -1
y= -1x + b
2. Use any cooresponding x and y values to substitute into the formula. Ex: (x,y) → (1,4)
y = mx + b
4 = -1(1) + b
4 = -1 + b
5 = b
3. Plug in the values found into the formula.
y = -1x + 5
Multiplying and Dividing Exponents are very easy.
When they are multiplied, we add the exponent numbers together.
When they are divided, we subtract the exponent numbers.
In this example,
/
We can conclude that
is 1 because,
any number to the power of 0 is 1
=
take the exponents alone:
-18+3 (Because it is multiplication) =-15
Final answer
