You decide to buy a custom frame for a painting which measures 4 by 6 inches. If the framing material costs $2 per inch, what is the total cost of framing material?
Answer:
6 x 4 = 24 x $2 = $48
Step-by-step explanation:
The total cost of the rectangular frame is C = $240.
What is rectangle?A rectangle is a two-dimensional shape in which the opposite sides are parallel and equal to each other and all four angles are right angles.
Given that, a painting measures 4 by 6 inches, the framing material costs $2 per inch,
We need to find the total cost of framing material
The perimeter is given by:
P = 2x(L + W)
In this case, we know that the frame is 6 inches by 14 inches, then the perimeter will be:
P = 2x(6in + 14in)
P = 2x20in = 40in
Since, the framing material costs $6 per inch, then the total cost of the frame will be:
cost = 40x$6 = $240

2x + 5y = -24
3x - 5y = 14
Solve by elimination
y and x
Answer:
x = -2
y = -4
Step-by-step explanation:
The way systems of equations work is that you have to substitute to solve for a variable *(only one of the 2 ways to figure this out)*
so, we will use addition property of equality in a form to add the two equations together, since +5y and -5y added together will cancel out.
that would leave
5x = -10
divide both sides by 5
x = -2
Now that we know x = -2, we can plug in -2 into one of the equations to find y.
2 ( -2) + 5y = -24
-4 + 5y = -24
-4 + 4 + 5y = -24 + 4
5y = -20
y = -4
x = -2
y = -4

PLEASE HELP Review the equation, then complete the following. f(x)=1/x-4, g(x)=4x+1/x Use composition to prove whether or not the functions are inverses of each other. Express the domain of the compositions using interval notation.
Answer:A. Yes, they are inverse of each other.
B. Domain and range of the compositions is .
Step-by-step explanation:
A. We have, and .
Now, 'when two functions f and g are inverses of each other, they satisfy the property '.
So, we have,
Thus, we get for the given function f and g, .
Hence, they are inverse of each other.
B. Now, as we have,
That is, the composition of the functions is equal to the identity function.
Thus, the domain and range are the set of all real numbers respectively.
So, in the interval notation, we have,
Domain and range of the compositions is .
For the following statements 11 - 16 write TRUE or FALSE.
11. Through any two points there is exactly two lines.
12. A line contains of at LEAST two points.
13. A plane contains at least three non-collinear points.
14. Two lines intersect at a point.
15. Two planes intersect at a point.
16. A line and a plane intersect at a line.
Answer:11 is false. Through any two points there is exactly one line. 12 is true. 13 is true. 14 is true. 15 is false. Two planes intersect at a line. 16 is false. A line and a plane would intersect at a point
