What is the value of -2xy if x = -1 and y = 6?
A. 12
B.-12
C. 26
D. 8
Answer: A
Step-by-step explanation:
If we are given the values of x and y, we just have to plug them into the expression. So -2xy means -2(-1)(6) which is 12. 12 corresponds to A so A is the correct answer.
Answer:
A , we find it like this :
-2(-1)(6)=12

find (g•f)(3) f(x)=3x-2 g(x)=x^2
Answer:
f(x)=3x-2
g(x)=x^2
(g o f)(3)=?
(g o f)(3)=g(f(3))
x=3→f(3)=3(3)-2
f(3)=9-2
f(3)=7
(g o f)(3)=g(f(3))=g(7)
x=7→g(7)=7^2
g(7)=49
Answer: (g o f)(3)=49
OR,if you like this answer can also work
For this case, the first thing we must do is the composition of functions.
We have:
f (x) = 3x-2
g (x) = x ^ 2
(gOf) (x) = (3x-2) ^ 2
We now evaluate the function:
(gOf) (3) = (3 * (3) -2) ^ 2
(gOf) (3) = (9-2) ^ 2
(gOf) (3) = (7) ^ 2
(gOf) (3) = 49
Answer:
(gOf) (3) = 49
Both are same

Given that ABCD is a rhombus, what is the value of x?
A. 18.25
B. 20.75
C. 30 O
D. 64
E. 86
F. Cannot be determined
Answer: 20.75
Step-by-step explanation:
X+(3x+7)+90=180
-90 on both sides
X+(3x+7)=83
-7 on both sides, add x’s
4x=83
Divide by 4 on both sides
X=20.75
The required measure of the value of x in the rhombus is 20.75.
What are angles?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
A fire of rhombus is shown,
Where the diagonal of the rhombus bisect each other at 90°.
let's assume the point at the intersection, is o.
Now, In triangle AOD the sum of the interior angle should be 180°,
x + 90 + 3x + 7 = 180
4x = 180 - 90 - 7
4x = 83
x = 20.75°
Thus. the required measure of the value of x in the rhombus is 20.75.

The mean of 8 and another number is 13. what is the other number?
Work Shown:
x = the unknown number
The mean of 8 and the unknown number is 13. This indicates we add up 8 and x, then divide by 2, and we'll get 13.
(8+x)/2 = 13
8+x = 2*13 .... multiply both sides by 2
8+x = 26
x = 26-8 .... subtract 8 from both sides
x = 18
As a check,
(8+18)/2 = 26/2 = 13
This shows the mean of {8,18} is 13.
The second number is 18.
Given to us,
First number, [tex]N_f = 8[/tex],
Mean of two numbers, [tex]m = 13[/tex]
Let us assume second number as x,
Also, we know mean is the arithmetic average of given numbers.
[tex]Mean =\dfrac{Sum\ of\ all\ the\ data\ given}{Numbere\ of\ data\ given}[/tex]
[tex]m=\dfrac{8+x}{2}\\\\13=\dfrac{8+x}{2}\\\\13\times 2 = 8+x\\8+x=26\\x=26-8\\x=18[/tex]
Hence, the second number is 18.

3 feet is how many meters? Hint: 1 ft = 0.305 m Round your answer to the nearest tenth.
Answer:
3 feet = 0.9 meters.
Step-by-step explanation:
If one foot equals 0.305 meters and you need to find how many meters three feet would be, you need to multiply 3 and 0.305. The answer is 0.915, and after rounding that to the nearest tenth, you get 0.9.
