The picture in the attached figure
let
AB=x
we know that
perimeter of the figure=10*x
perimeter=42.5 cm
so
42.5=10*x
x=42.5/10
x=4.25 cm
area of the figure=area of rectangle +area of square
area of rectangle=4.25*(4.25*3)----> 54.1875 cm²
area of square=4.25²----> 18.0625 cm²
area of the figure=54.1875+18.0625-----> 72.25 cm²
the answer is72.25 cm²
Answer:
Step-by-step explanation:
The slope is given to you by the line y = 1/4 x
The slope is just read as the number in front of x providing that the coefficient of y is 1. If that is not so, then you must divide by the coefficient in front of y. So far what you have is y = 1/4 x + b.
The second part of the question is to use the given point to find b.
x = 4
y = -1
b = ? substitute x and y to find b
y = 1/4 * 4 + b
- 1 = 1/4 * 4 + b
-1 = 1 + b
-2 = b
The equation of the line is y = 1/4 x - 2 Just to confirm this, I'm going to include the graph with the point 4,-1 on it.

Answer:
the answer to (8.4 × 102) (2.5 × 106) = 227,052
Inverse of the function 2x-6y=1
To get the inverse of the function, first, interchanged
the variables such x will be y and y will be x.
<span>(1) </span><span> 2y – 6x = 1</span>
Then, find the value of y in the new equation,
<span>(2) </span><span> 2y – 6x + 6x = 1 + 6x</span>
2y
= 1 + 6x
<span>(3) </span>(1/2)(2y)
= (1 + 6x)(1/2)
<span> y = (1 + 6x) / 2</span>
<span>The reverse of the function
is y
= (1 + 6x)/2.</span>
