The product of two positive integers is always POSITIVE . The product of two negative integers is always POSITIVE. The product of a positive integer and a negative integer is always NEGATIVE . The product of any integer and –1 is always THE OPPOSITE OF THAT INTEGER .
1. F(3)= -2(3)-5
-6-5
F(3)=-11
2. F(3)= -2(3)^2-4
-6^2-4
36-4
F(3)=32
3. F(x)=−2x−5
For: x=−2, f(x) is:f(−2)=(−2×−2)−5=4−5=−1
For: x=−1, f(x) is:f(−1)=(−2×−1)−5=2−5=−3
For: x=1, f(x) is:f(1)=(−2×1)−5=−2−5=−7
For: x=2, f(x) is:f(2)=(−2×2)−5=−4−5=−9
The Range is:
{−1,−3,−7,−9}
4. -80, -110
Its the middle two. Hope I helped
According to the represented datum, the correct answer is : equation has no solution; therefore, the system of equations has no solution because it is imposible <span> when girl should rich 0 = 60.
I am pretty sure it helps! Do hope you will agree with me.</span>
