Answer: D) Full circle on -2 and arrow pointing to the right.
Step-by-step explanation:
add 3
multiply by the negative reciprocal of the fraction. (<u>NOTE:</u> When multiplying or dividing by negative numbers, the inequality sign flips.)
This tells us that x has to be greater than or equal to -2
Answer: what is the question
Step-by-step explanation:
The x-intercept of the graph is (4 , 0)
Step-by-step explanation:
Let us revise the meaning of x-intercept and y-intercept
- x-intercept means value x when y = 0
- That means the graph intersects x-axis at point (a , 0), where a the value of x when y = 0
- y-intercept means value of y when x = 0
- That means the graph intersects y-axis at point (0 , b), where b is the value of y when x = 0
∵ 5x - 4y = 20 is the equation of the graph
- To find x-intercept substitute y by 0
∵ y = 0
∴ 5x - 4(0) = 20
∴ 5x - 0 = 20
∴ 5x = 20
- Divide both sides by 5
∴ x = 4
The x-intercept of the graph is (4 , 0)

Answer:
-0.25 units
Step-by-step explanation:
144x^2 - 72x + 9 = 0
common factor: 9
16x^2 - 8x + 1 = 0
(4x + 1)^2 = 0
4x +1 = 0
4x = -1
x = -0.25 units
Answer:
3
Step-by-step explanation:
If you start at any point on the line, you can go up 3 points and go to the right by 1 point to get back to the line. This is where you get the number 3 because 3/1 is 3.
