Answer:
5x²- 1.8
Step-by-step explanation:
roots are -3 and 3, put them in brackets
(x - 3)(x + 3)
x² + 3x - 3x - 9
x² - 9
5x = -9
x = -1.8
5x² - 1.8
just to check:
5x² - 1.8
x² - 9
(x - 3)(x - 3)
x = -3 and 3.
PART A: The equation I used is y<span>≥-1x+4. The line will be graphed going diagonally from the second quadrant to the fourth quadrant and shaded above the line.
PART B: Plug in the coordinates for point C and F into the equation from PART A and solve them to make sure the statements are true. You should end up with 2</span>≥2 for point C and 4<span>≥1 for point F.
PART C: First graph the equation and then shade below the line. Next, identify all the points in the shaded area.
I hope this helps you! I have provided pictures of both equations for reference. The first picture is for PART A and PART B. The second picture is for PART C. Let me know if I'm correct :)</span>
140 changed to a percent would be 1.4 (divide by 100), and rounded the nearest tenth would be 1.4.
