Answer:
Option D. 9
Step-by-step explanation:
There are two ways to obtain the answer to the question.
Method 1:
Let 2x + 1 = 0
Making x the subject, we have
2x + 1 = 0
Collect like terms
2x = –1
Divide both side by 2
x = –1/2
Now, put the value of x into the expression 4x³ – 6x² – 8x + 7, we have:
4x³ – 6x² – 8x + 7
x = –1/2
4(–1/2)³ – 6(–1/2)² – 8(–1/2) + 7
4(–1/8) – 6(1/4) – 8(–1/2) + 7
–1/2 – 3/2 + 4 +7
– 4/2 + 4 + 7
– 2 + 4 + 7
= 9
Method 2:
Divide 4x³ – 6x² – 8x + 7 by 2x + 1
Please see attached photo for explanation.
It looks like your equation repeated twice. I'm assuming it's 6x + y = 6.
I'm going to put your equation into slope-intercept form: y = - 6x + 6.
For the slope to be perpendicular, we do the opposite reciprocal of the slope given. So your slope of a perpendicular line is 1/6.
Answer:
C. -3(√y)(∛x²)
Step-by-step explanation:
Recall the rule for exponents with fractions. The numerator represents the power the variable is raised by, and the denominator represents the which root will be taken.
y^1/2 equals √y
and x^2/3 equals ∛x²
So the answer is -3(√y)(∛x²)
