There are four pairs (m,n) that work: (5,10), (6,6), (8,4), and (12,3).
212 divided by 8 is 26.5. I hope this helps you!
Gradient= -3/2 Equation: Y=mx+c Y=2 , X=8
So you substitute the numbers in
2=(-3/2) x 2 + c (then you backtrack to solve for c which is the y intercept)
2=-3+c
5=c So the equation should be Y=-3/2x+5
1. You con solve the quadratic equation x^2+20x+100=50<span> by following the proccedure below:
2. Pass the number 50 from the right member to the left member. Then you obtain:
x^2+20x+100-50=0
</span><span> x^2+20x+50=0
</span><span>
3. Then, you must apply the quadratic equation, which is:
x=(-b±√(b^2-4ac))/2a
</span><span>x^2+20x+50=0
</span><span>
a=1
b=20
c=50
4. Therefore, when you substitute the values into the quadratic equation and simplify ir, you obtain that the result is:
-10</span>±5√2 (It is the last option).
