Answer:
Its used for the domain and it means "the members of all REAL numbers" which refers to their being no imaginary number, for instance in inequalities that have square roots, it cant be a negative number otherwise you will get a imaginary number.
Step-by-step explanation:
For simple integer factors as this one has, you want to find two values for the quadratic in the form ax^2+bx+c. Let the two values be j and k. These two values must satisfy two conditions.
jk=ac=10 and j+k=b=11, so j and k must be 1 and 10.
Now replace bx with jx and kx...
2x^2+x+10x+5 now factor 1st and 2nd pair of terms.
x(2x+1)+5(2x+1)
(x+5)(2x+1)
Answer:
Your eyes: 1+1, Legs of a dog: 2+2, Your fingers: 5+5, Etc.

Answer:
x = -7
Step-by-step explanation:
See the photo attached.
The correct answer would be 2,656.25 because you take the 8.5% and move the decimal 2 places to the left.
Now multiply the total (250,000) by .085% and you get $21,250
You will now take 21,250 and divide it by 8 giving you the answer.
