What you can do is multiply the denominator, or bottom number, by two. Remember, what you do to the top, you do to the bottom. 4*2 is 8 and 1*2 is 2. So, now your fraction has become 2/4. Also, 2 is equivalent to 3/1, because 2 divided by 1 is still 2.
Answer:
xy1
Step-by-step explanation:
Correct option is C)
Given two equations are 2x+y+4=0 and x=3y+7=0
let us consider 2 equations ax+by+c=0 and mx+ny+p=0
By cross multiplication method ,the equations obtained will be ,
b×p−n×c
x
=
c×m−a×p
y
=
a×n−b×m

x
=
4−14
y
=
6−1

Answer:
Width = 12 feet
Length = 20 feet
Step-by-step explanation:
The area of a rectangle is A = l*w. Here the length is 8 feet more than the width or 8 + w and the width is w. So the area is A = w(8+w) = 8w + w²
If the dimensions are changed then the expressions will change. The width is increased by 4 feet. This means the width w becomes w + 4. The length is decreased by 5 feet. This means the length becomes 8 + w - 5 = 3 + w. So the area of the new triangle is A = (w+4)(3+w) = w² + 7w + 12.
Since the areas are the same, set them equal to each other and solve for w.
w² + 7w + 12 = 8w + w² Subtract w² from both sides.
7w + 12 = 8w Subtract 7w from both sides.
12 = w
The original width w is 12 feet. This means the original length which was 8 + w = 8 + 12 = 20 feet.

From the graph shown, you can see that the point of intersection is -3.464 and ≈ 3.464.
<h3>Functions and values</h3>
Given the following functions
f(x)= log (x-1)
g(x)= 1/2x^2 - 4
If both functions are equal then;
log(x+1) = 1/2x^2-4
In order to determine the solution, we will plot both equations on a graph and locate the point where both curves meet
From the graph shown, you can see that the point of intersection is -3.464 and ≈ 3.464.
