The x axis is labeled as Number of days.
<h3 /><h3>What is graph?</h3>
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
let x be the number of days and y be money.
So, the equation is
y = -7x + 150.
Hence, the x axis is labeled as Number of days.

Let the initial point of the vector be (x,y). Then the magnitude of the vector v can be written as:

The magnitude of vecor v is given to be 10. So we can write:

Now from the given options, we have to check which one satisfies the above equation. That point will be the initial point of the vector.
The point in option d, satisfies the equation.
Thus, the answer to this question is option D
I don't really like these algebra problems which pretend to be geometry.
The bisector makes two equal angles, so
x/2 + 17 = x - 33
50 = (1/2) x
x = 100
That means ABC = 100/2 + 17 = 67 degrees
CBD = 100 - 33 = 67 degrees, equal so that checks
We're asked for ABC which is 67 + 67 = 134 degrees
Answer: 134°

Step-by-step explanation:
Answer: Length = 28cm
Width = 7cm
Step-by-step explanation:
Let the width be represented by x.
Since the length is four times its width. Therefore, the length would be:
= 4 × x = 4x
The perimeter of a rectangle is calculated as:
= 2(length + breadth)
Therefore, 2(4x + x) = 70
2(5x) = 70
10x = 70
x = 70/10
x = 7
Therefore, width = 7cm
Length = 4x = 4 × 7 = 28cm
