IT'S meep 4x – 10 = x2 – 5x + 10 ( y = 4x - 10 is substitute for y).................
PROOF: y + 5x = x²<span> + 10
</span> (4x - 10) + 5x = x² + 10
4x - 10 = x² -5x + 10
<span>
</span>0 = x2 – 9x + 20<span> (liked terms are grouped and simplified)....
PROOF: </span> 4x - 10 = x² -5x + 10
4x = x² -5x + 10 + 10
0 = x² -5x -4x + 20
0 = x² - 9x + 20
Solving:
x² - 9x + 20 = 0
x² - 5x - 4x + 20 = 0
(x - 5) (x - 4) = 0
⇒ x = 4 (as question says) OR x = 5......
Answer:
i think its because it is an odd number im in middle school so im not sure but let me know if this is right
Step-by-step explanation:
Answer: y=-8x-5
Step-by-step explanation:
find the two points
mark the first x poin x1 and the second x poin x2 amd the first y point y1 and the second y point y2 then subtract y1 by y2 and then undeeneath that subrtrax x1 by x2 and y intercept is b.
