The value of the function f(x)=3(4-x) when x=7 is -9. This is calculated by substituting x=7 into the function and simplifying.
To find the value of the function f(x)=3(4-x) when x=7, you should insert x's value into the equation. Therefore, the function takes the form: f(7)=3(4-7). Then you simplify it to: f(7)=3(-3) and further simplification gives: f(7)=-9.

Round your answer to the nearest hundredth.
Answer:
We have the equation A*C = A
Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.
We can divide both sides by A and get:
(A*C)/A = A/A
C = 1
So here we finded the value of A.
If A and C are matrices, then C is the identity matrix.
The given statement is mathematically impossible, as there is no number that is equal to both itself and its opposite. Therefore, the answer is undefined.
In other words, there is no number that can be substituted for both A and C in the equation AC = A, C to make it a true statement.
Here is a more detailed explanation:
If A is equal to zero, then C would also have to be equal to zero. But this would mean that AC = 0, which is not equal to A, C.
If A is any other number, then C would have to be equal to the negative of A. But this would mean that AC = -A, which is not equal to A, C.
Therefore, there is no solution to the equation AC = A, C.

Answer:
675= 3.14× r²
r²= 675/ 3.14
r²=214.968
radius=14.66 meters
diameter= 2× radius
diameter= 2× 14.66
diameter = 29.32 meters
The definition of complex, real and pure imaginary number is as follows:
The absolute value of this number is given by:
So, the absolute value of a complex number represents the distance between the origin and the point in the complex plane. On the other hand, the absolute value of a real number means only how far a number is from zero without considering any direction.
Answer: x = - 10
Step-by-step explanation:
a) Linear Pair: 138 + ∠a = 180° --> ∠a = 42°
b) Triangle Sum Theorem: ∠a + 2∠b = 180° --> ∠b = 69°
c) Vertical Angles Theorem: ∠b = ∠c --> ∠c = 69°
d) Congruent sides implies congruent angles: ∠c = ∠d --> ∠d = 69°
∠2) Triangle Sum Theorem: ∠c + ∠d + ∠2 = 180°
69° + 69° + ∠2 = 180°
∠2 = 42
x) m∠2 = 42
x + 52 = 42
x = -10
