Answer:
see explanation
Step-by-step explanation:
Given a line with a slope of zero.
This is a horizontal line parallel to the x- axis.
The equation of the line is y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (0, 4 ) with a y- coordinate of 4, thus
Equation of line is y = 4
Thus
The line is horizontal
The line goes through (4, 4 )
The y- values are all 4
Answer:
![A=2x^2+3x-5](https://tex.z-dn.net/?f=A%3D2x%5E2%2B3x-5)
Step-by-step explanation:
Given that,
Length = (2x+5) cm
Width = (x-1) cm
We need to find the area of a rectangle. The formula for the area of rectangle is given by :
A = lb
![A=(2x+5)(x-1)\\\\=2x^2-2x+5x-5\\\\=2x^2+3x-5](https://tex.z-dn.net/?f=A%3D%282x%2B5%29%28x-1%29%5C%5C%5C%5C%3D2x%5E2-2x%2B5x-5%5C%5C%5C%5C%3D2x%5E2%2B3x-5)
So, the required area is equal to
.
Answer:
10 inches
Step-by-step explanation:
The length of the playground in its actual size is 120 feet.
The scale drawing uses a scale of 1 inch to 12 feet.
This means that 1 inch in the drawing equals 12 feet in actual size.
Therefore, the length of the playground on the scale drawing is:
1 inch = 12 feet
x = 120 feet
Cross-multiply:
120 * 1 = 12 * x
=> x = 120 / 12 = 10 inches
The length of a side of the playground on the scale drawing is 10 inches.
