Y + 1 = -1/4(x - 5)
y + 1 = -1/4x + 5/4
y = -1/4x + 1/4
B. y = -1/4x + 1/4
Answer:
Length = 13 cm
Width = 10 cm
Step-by-step explanation:
We are told that;
- The length of the rectangle is 3 cm more than the width
- Thus taking, the width as x cm
- Then, the length will be (x+3) cm
- The perimeter of the rectangle is 46 cm
We are required to determine the dimensions of the rectangle;
We know that the perimeter of a rectangle is given by the formula;
P = 2(l+w)
In this case;
46 = 2 ( x + x + 3)
Thus;
4x + 6 = 46
Solving for x,
4x = 40
x = 10
This means, the width is 10 cm, while the length is 13 cm
Therefore, the dimensions of the rectangle is length 13 cm and width 10 cm
Given the question, it needs the points so that the equation can be evaluated and to know if the points is a solution to the equation or not.

64

→ √x = 8
Now, squaring both sides in order to calculate the value of x.
→ (√x)² = (8)²
→ <u>x = 64</u>
Therefore, the value of x is 64.
