The slope between the points (x1,y1) and (x2,y2) is
slope=(y2-y1)/(x2-x1)
(0,6) and (5,-4)
x1=0
y1=6
x2=5
y2=-4
slope=(-4-6)/(5-0)=-10/5=-2
slope=-2
<span>x^2-15=34
</span><span>x^2 = 34 + 15
</span><span>x^2 = 19
x = + 7 and x = -7
answer is
</span>x = + 7 and x = -7
Depends on his credit score. not enough info, IE: credit score, answer choices, interest rate.
My guess would be having an interest rate of 7.5% the answer would be:
His total interest would be $718.94
X² - x - 20
x² -5x+4x - 20
x(x-5) +4(x-5)
(x+4) (x-5)
