Answer:

f(-8) = 1.8

Step-by-step explanation:

See the graph of a given function which is attached to the question given.

The graph of y = f(x) is plotted in the graph and we have to find the value of y at x = - 8 i.e. f(-8).

It is clear from the graph that the value of y corresponding to the value of x = -8 is slightly lower than 2.

Therefore, we can approximate the value of f(-8) as 1.8. (Answer)

When simplifying 4x^3-10x^2+6x/2x^3+x^2-3x, what are the term(s) that can be cancelled

brilliants [131]

Answer:

x can be cancelled

Step-by-step explanation:

we are given

$\frac{4x^3-10x^2+6x}{2x^3+x^2-3x}$

Firstly, we will factor numerator and denominator

and then we can factor it

$4x^3-10x^2+6x=2x(2x^2-5x+3)$

$4x^3-10x^2+6x=2x(2x+1)(x-3)$

now, we can factor denominator

$2x^3+x^2-3x=x(2x^2+x-3)$

$2x^3+x^2-3x=x(x-1)(2x+3)$

now, we can replace it

$\frac{4x^3-10x^2+6x}{2x^3+x^2-3x}=\frac{2x(2x+1)(x-3)}{x(x-1)(2x+3)}$

we can see that

both terms are having x common

so, x can be cancelled

So,

x can be cancelled

3x + 6y = 4y - 4

gulaghasi [49]

Answer: y = 2/3x + 41/3

Step-by-step explanation:

First convert the equation into slope-intercept

3x + 6y = 4y - 4

-4y -4y

3x + 2y = -4

-3x -3x

2y = -3x - 4

y = -3/2x - 2

Perpendicular lines have a negative reciprocal for their slopes.

The negative reciprocal of -3/2 is 2/3

Now using the slope 2/3 you will use the formula y =mx +b and input the slope, and the x and y coordinates of the given point, (-10,7), to solve for the y-intercept.

7 = 2/3(-10) + b

7 = -20/ 3 + b

+ 20/3 + 20/3

b = 20/3 + 21/3 = 41/3

Since the the y-intercept is 41/3 then the equation will be , y = 2/3x + 41/3

Solve using long division.

Mkey [24]

Answer:

Quotient is $3x-5$ and remainder is 0.

Step-by-step explanation:

Given:

Dividend = $3x^2+7x-20$

Divisor = $x+4$

The long division is shown in the attachment.

Step 1: we need to divide $3x^2+7x-20$ with $x+4$ we first multiply $x+4$ with 3x we get the remainder as $-5x-20$

Quotient as 3x.

Step 2: Now the dividend is $-5x-20$ and divisor $x+4$ now we will multiply $x+4$ with -5 we get the remainder as 0 and Quotient as $3x-5$

Hence Quotient is $3x-5$ and remainder is 0.
