Answer:
option 1
Step-by-step explanation:
i was just doing that question
f(x) - g(x)
=> (3x² + x - 3) - (x² - 5x + 1)
=> 3x² + x - 3 - x² + 5x - 1
=> 3x² - x² + x + 5x - 3 - 1
=> 2x² + 6x - 4
Answer:
2 1/2
Step-by-step explanation:
(5/8) x 4 = 20/8 = 2 1/2
Answer:
In the equation y = mx + c the value of m is called the slope, (or gradient), of the line. It can be positive, negative or zero. The value of c is called the vertical intercept of the line. It is the value of y when x = 0. When drawing a line, c gives the position where the line cuts the vertical axis.

Answer:
1. -1/2
2. -2/3
4. 0
5. -3/4
Step-by-step explanation:
Parallel lines have the same slope. To find the slope from the equation, use the form y=mx +b by finding m.
1. y= -1/2x - 1 has m=-1/2. This is the same slope for the parallel line.
2. y = -2/3x -1 has m = -2/3. This is the same slope for the parallel line.
4. y = 6 is a line through the y-intercept 6 on the y-axis. Because this is a horizontal line, the slope is 0. A parallel line will have 0 as the slope too.
5. 3x + 4y = 12 needs to be converted to y =mx+b.
4y = -3x +12
y= -3/4 x + 3
The slope is -3/4 so the parallel line will have the same slope.
