Answer:

4x³ - 4x² - 4x -8  

Step-by-step explanation:

It is given that,

4x³ - 12x² - 5 -(-8x² + 4x + 3) -----(1)

This expression shows the subtraction of two algebraic expression.

Let eq(1) 4x³ - 12x² - 5 -(-8x² + 4x + 3)

⇒4x³ - 12x² - 5 +8x² - 4x - 3  (open bracket)

= 4x³ - 12x² + 8x² - 4x -5 -3  (write similar terms together)

= 4x³ - 4x² - 4x -8  

Therefore the difference of 4x³ - 12x² - 5 -(-8x² + 4x + 3) is given by,

4x³ - 4x² - 4x -8

Answer:

4x³-4x²-4x-8

Step-by-step explanation:

We have given an expression.

(4x³-12x²-5) - (-8x²+4x+3)

We have to simplify above expression.

Open parentheses and distribute negative sign on second parentheses.

4x³-12x²-5+8x²-4x-3

Collect like terms

4x³-12x²+8x²-4x-5-3

Add the coefficients of x² and constant

4x³+(-12+8)x²-4x+(-5-3)

Simplify

4x³+(-4)x²-4x+(-8)

4x³-4x²-4x-8 which is the answer.

Plz help me with this
Marrrta [24]

Answer:  c) 3

<u>Step-by-step explanation:</u>

Plug in y = -9 and the given x-value to see if it makes a true statement.

a) -4.5 falls in the piecewise function x < -3  --> y = -x

y = -x

-9 = -(-4.5)

-9 = 4.5    FALSE

b) -3 falls in the piecewise function -3 ≤ x ≤ -2  --> y = 2x

y = 2x

-9 = 2(-3)

-9 = -6    FALSE

c) 3 falls in the piecewise function x > -2 --> y = -x²

y = -x²

-9 = -(-3)²

-9 = -9   TRUE

d) 9 falls in the piecewise function x > -2 --> y = -x²

y = -x²

-9 = -(9)²

-9 = -81   FALSE

Gerri spends 1/21 of her money on pencils and 2/21 on paper. What fraction of her money does she spend. Give the answer in simpl
BigorU [14]

Answer:

Gerri spends 1/7 (A).

Step-by-step explanation:

If Gerri spends 1/21 of her money on pencils and 2/21 of her money on paper, adding these two fractions together will give us the total fraction of her money that she spent.  Since 1/21 and 2/21 have the same denominator, we can add the numerators to get 3/21.  However, fractions must always be in simplest form, meaning if the numerator (top number) and denominator (bottom number) can both be divided evenly by the same factor, then the fraction can be simplied to lower numbers.  In this case the number 3 and the number 21 can both be divided evenly by 3:  (3÷3)/21÷3) = 1/7.
