f(1/2) = 1
Step-by-step explanation:
Given 3(x-2)=6, then x is equal to:
Select one:
A.5
b.4
c. 2
d.6
Answer:
[tex]\boxed {\boxed {\sf B. \ 4}}[/tex]
Step-by-step explanation:
We are given the following equation.
[tex]3(x-2)=6[/tex]
We are solving for x, so we must isolate the variable using the inverse operation.
(x-2) is being multiplied by 3. The inverse operation of multiplication is division, so we divide both sides of the equation by 3.
[tex]\frac {3(x-2)}{3}= \frac{6}{3}[/tex]
[tex](x-2)= \frac{6}{3}[/tex]
[tex](x-2)= 2[/tex]
2 is being subtracted from x. The inverse operation of subtraction is addition, so we add 2 to both sides of the equation.
[tex](x-2)+2= 2+2[/tex]
[tex]x=2+2[/tex]
[tex]x=4[/tex]
Check the answer by plugging 4 in for x in the original equation.
[tex]3(x-2)= 6[/tex]
[tex]3(4-2)= 6[/tex]
[tex]3(2)= 6[/tex]
[tex]6=6[/tex]
This checks out, so we know our answer is correct. x is equal to 4 and choice B is correct.

Answer:
[tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1
Step-by-step explanation:
By subtracting x³ - 3x² + x - 1 , that is
[tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - (x³ - 3x² + x - 1) ← distribute by - 1
= [tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - x³ + 3x² - x + 1 ← collect like terms
= [tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1
Step-by-step explanation:
x⁴ + 5x³ - 6x² - 5x - 2
should become
x³ - 3x² + x -1
so, what do I need to subtract from the top terms to get the bottom terms ?
because we can only look from one x- term to the next. we can only combine them, when they have the same x exponent.
so, we see there is no x⁴ in the desired result.
therefore, we know as a first item that x⁴ had to be subtracted.
the next x exponent is 3.
we have 5x³ on the top, and x³ on the bottom.
so, clearly, we need to subtract 4x³ as second term.
the next x exponent is 2.
we have -6x² on the top, and -3x² on the bottom.
so, we should actually add 3x². and how do we do this in a subtraction ? by subtracting a negative value, which actual adds it.
so, we need to subtract -3x² as third term.
the next x exponent is 1 (just x).
we have -5x on the top and x on the bottom.
so, the same trick as before, as we need to add something.
so, we need to subtract -6x as fourth term.
and finally, the x exponent 0, which just shows the constant numbers.
we have -2 on the top and -1 on the bottom.
again the same trick to actually add 1.
we need to subtract -1 as fifth term.
so, in total, this is what we need to subtract from the top line to get the bottom line :
x⁴ + 4x³ - 3x² - 6x - 1
1 + 2 + (-5) + 4
A . -6
B . -5
C . 0
D . 2
E . 4
F . 12

HOPE THIS HELPS YOU......What are the coordinates of the midpoint at (-3,9) and (10,18)
Answer:
(7/2, 27/2) or (3.5, 13.5)
Step-by-step explanation:
The x-coordinate of the midpoint is the average of the x-coordinates of the endpoints.
The y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.
x-coordinate of the midpoint:
(-3 + 10)/2 = 7/2
y-coordinate of the midpoint:
(9 + 8)/2 = 27/2
Answer: (7/2, 27/2) or (3.5, 13.5)
