Express the polynomial below by nesting. f(x)=4x³+3x²+2x-4​
BabaBlast [244]

Answer:

f(x)=4x^{3} +3x^{2} +2x-4 can be expressed in nested form as ((4x+3)x+2)x-4

Step-by-step explanation:

Considering the polynomial

f(x)=4x^{3} +3x^{2} +2x-4

Expressing the polynomial by nesting

So,

f(x)=4x^{3} +3x^{2} +2x-4

Step 1) Writing down the coefficient and one factor of x from the first term and add on the coefficient of the next term.

4x+3

Step 2) Enclose this term in brackets, multiply by x and add on the next coefficient.

(4x+3)x+2

Step 3) Repeating the previous step until all terms are within the equation.

So,

((4x+3)x+2)x-4

Therefore, f(x)=4x^{3} +3x^{2} +2x-4 can be expressed in nested form as ((4x+3)x+2)x-4

Solve this system for brainliest answer!!!<br><br> 3.75x+4y=2,160<br> x+y=550
djyliett [7]
First solve the second equation to equal x.

x + y = 550

Subtract y from both sides.

x = 550 - y

Put this into the first equation in place of x.

3.75 (550 - y) + 4y = 2160

Multiply everything in the parenthesis by 3.75

2062.5 - 3.75y + 4y = 2160

Combine like terms.

2062.5 + 0.25y = 2160

Subtract 2062.5 from both sides.

0.25y = 97.5

Divide 0.25 on both sides.

y = 390

Put this into the second equation in place of y.

x + 390 = 550

Subtract 390 from both sides.

x = 160

So x = 160 and y = 390

Hope this helps!

What is the equation of a line that passes through the point (1, 8) and is perpendicular to the line whose equation is y=x2+3 ?
VladimirAG [237]
Important:  If you're discussing squares, please express "the square of x" as x^2 (not as x2).  

Please note that your y=x^2+3 is NOT a line.  I will assume (probably incorrectly!) that you meant y=2x+3.  The slope of this line is 2, so the slope of any line perpendicular to y=2x+3 is -1/2.

Now use the point-slope equation of a straight line:

y-8 = (-1/2)(x-1)   (answer)

Frannie currently weighs 41 pounds. The vet would like to see her weigh 36 pounds. What percent of her body weight does she need
baherus [9]
Frannie’s vet would like her to lose 12% of her body weight. You find this by subtracting 41-36=5 and then finding that .12x41 also equals 5, therefore 12% of 41 is 5.
