Answer:
step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)
step 2. so the question becomes is C a quadratic
step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4
step 4. write out the y values: -126, -14, 2, 18
step 5. write out the differences: 140, 16, 16
step 6. write out the differences: -124, 0.
step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't
step 8. C is not a quadratic.
Answer:
Rewrite the equation as x+xyz=wx+xyz=w.
x+xyz=wx+xyz=w
Subtract xx from both sides of the equation.
xyz=w−xxyz=w-x
Divide each term by xzxz and simplif
Sorry I don’t have roller
Hope it’s right
Best luck with your studying
Hi there,
a. 18(26) →18 × 26 = 468
b. 6(3405) → 6 × 3405 = 20,430
c. 21(35) → 21 × 35 = 735
The numbers in bold are the answers. Hope this helps and have a phenomenal day!
