You need to put everything to one side and equal to 120. Then you combine all like terms.
then you subtract 24 with 120. You get 94/24=4

10x+6x+16+8x+8=120
24x+24=120
-24 -24
____________
24x=96
/24 /24
X=4

Determine the end behavior of the polynomial function. f(x)=-3x^4-2x^3+2x^2+ 3x +5 a) falls to the left and rises to the right b
Molodets [167]

Answer:

Option b is correct

Step-by-step explanation:

In order to check the end behavior of a  polynomial function we   just check the leading term and its coefficient and the procedure is as  follows:

Here we can see that highest exponent of the polynomial function is 4

therefore degree of the polynomial is 4. and therefore  -3x^4 is leading term.  

because of even degree it will be same from both ends that is either both sides rises or both sides falls. Since number in the front of  leading is negative therefore it falls at both ends. that is  falls to  the left and falls to the right.

therefore option b is correct.

Parallel and perpendicular line (4,7);y3x+6
enyata [817]

Answer:

Parallel Line: y = 3x - 5

Perpendicular Line: y = -1/3x + 25/3

Step-by-step explanation:

The equation given is a linear equation in slope-intercept form, y = mx + b, where m = slope and b = y-intercept.  With lines that are parallel to each other, they containt the same slope.  So, to form an equation of a line that is parallel to the first equation, the slope = 3.  Using the given point (4, 7), x = 4 and y = 7, we can use our slope-intercept form to solve for 'b':

7 = (3)(4) + b or 7 = 12 + b or b = -5

So, our equation for a parallel line would be: y = 3x - 5.

For perpendicular lines, the slope must be the opposite reciprocal of the slope from the first equation.  So, if m = 3, than the slope of the perpendicular line must be - 1/3.  Using the same point (4, 7) we can use our slope-intercept form to solve for 'b':  

7 = (-1/3)(4) + b or 7 = -4/3 + b or b = 25/3

So, our equation for a perpendicular line would be: y = -1/3x + 25/3

Factor completely 10x^3+2x^2+5x+1
liubo4ka [24]

Answer:

\boxed{\bold{\left(5x+1\right)\left(2x^2+1\right)}}

Explanation:

Factor Out \bold{2x^2} From \bold{10x^3+2x^2: \ 2x^2\left(5x+1\right)}

= \bold{\left(5x+1\right)+2x^2\left(5x+1\right)}

Factor Out Common Term 5x + 1

= \bold{\left(5x+1\right)\left(2x^2+1\right)}

\bold{\italic{Mordancy}}

Please someone help!!!!!!!!!!!!!!!!!!
serg [7]

Answer:

  g(x)=-\sqrt[3]{x-1}

Step-by-step explanation:

g(x) = -f(x) does a reflection over the x-axis.

g(x) = f(x -1) translates the graph right 1 unit.

The graph shown has both of these transformations, so is ...

  g(x) = -f(x -1)

  g(x) = -∛(x -1)
