I also worked it out but I got -5/3
2(6p-5) ≥ 3(p-8) -1
12p-10 ≥ 3p-24-1
12p-10 ≥ 3p-25
12p-3p ≥ -25+10
9p ≥ -15
-15/9
P ≥ -5/3
Not sure about the second question, but for the first one x=21
I’ve never heard of a similarity statement, so sorry about that. Good luck man!
Interest is 3.20 per 100
3.2 × 275/100
=3.2 × 2.75
answer A $8.80
I have a solution here however with a slight change in the equation:
<span> f(x)=3x^2-6x+1
My solution is:
</span>The domain is all real numbers--there are no restrictions like a square root or variable in the denominator
<span>
this is a U shape parabola and you want to find the bottom point, it is at the vertex </span>
<span>x=-b/2a =- (-6) /2 (3) =1 </span>
<span>f(1) =3(1)^2 -6(1) +1 =3-6+1 =-2 </span>
<span>the minimum is (1, -2) </span>
<span>so the range is all real numbers >= -2
</span>
By examining my solution, you could just answer the problem on your own! I hope it helps!
