The value of x that will result for the rational expression to be undefined will be the values that will give 0 value for the denominator.
A. 7
<span>2(7)^2 -32 = 66
</span>
<span>B. 4
</span>2(4)^2 -32 = 0 <span>-------> undefined</span>
C. 2
2(2)^2 -32 = -24
<span>D. -2
</span>2(-2)^2 -32 = -24
<span>E. -4
</span>2(-4)^2 -32 = 0 -------> undefined
F. -7
2(-7)^2 -32 = 66
Answer:
I believe the answer would be none of them are functions.
(2/5)(x-2)=4x
multily both sides by 5/2 (2/5 times 5/2=10/10=1)
1(x-2)=20x/2
x-2=10x
minus x both sides
-2=9x
divide 9
-2/9=x
Answer:
His overall grade is 87
Step-by-step explanation:
This grade is a weighed average.
The student got 88 on the homework. The homework is 50% of the grade.
The student got 80 on the midterm exam, that is 20% of the grade.
The student got 90 on the final exam, that is 30% of the grade.
His overall grade is:
G = 0.5*88 + 0.2*80 + 0.3*90 = 87
His overall grade is 87
