Answer: 216.75 in^2
Step-by-step explanation: area = 8.5 x (8.5x3)
8.5 x25.5
Step-by-step explanation:
Change the sign of inequality to sign of equation.
First step:
Calculate the coordinates of two points of a line.
Choice any two values of x, put it to the equation and calculate the values of y.
Example:
y > 2x + 1 → y = 2x + 1
for x = 0 → y = 2(0) + 1 = 0 + 1 = 1 → (0, 1)
for x = -1 → y = 2(-1) + 1 = -2 + 1 = -1 → (-1, -1)
Draw a line passing through the given points.
If is < or >, then draw dot line.
If is ≤ or ≥, then draw solid line.
In our example, we have an inequality sign: >. Therefore, draw a dot line.
Second step:
Shading region:
If is < or ≤ - shading to the left.
If is > or ≥ - shading to the right.
In our example, we have an inequality sign: >. Therefore, shading to the right.
Equation of the given line is:
y = 3x + 2
Slope of the line = m = 3
Since we are to find equation of line parallel to this line, the slope of new line will be the same as slope of parallel lines is the same.
So we are to find a line with slope 3 and passing through the point (10,1). Using the point-slope form of equation we can write:
y - 1 = 3(x - 10)
y = 3x - 30 + 1
y = 3x - 29
⇒
- 3x + y = 29
So option C gives the correct equation of the line.
