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:
For the given function, Slope is and y-intercept is -2.
Step-by-step explanation:
The given function in x is :
.....1
Since, we know that the general form of equation of a line is :
.....2
where, y is the dependent variable, x is independent variable, m is the slope and c is the y intercept of the line.
On comparing equation 1 and 2, we get :
;
; and
;
Thus, we can conclude that
slope of function is and y-intercept is -2.
