Answer:

M = 7x² +21

Step-by-step explanation:

Subtract the unwanted terms on the left from both sides.

(-7x² +6x -16) + M = 6x +5

M = 6x +5 -(-7x² +6x -16)

M = 7x² +21 . . . . simplify

Answer:

Suit: $13; Shoes: $8

Step-by-step explanation:

Represent the unknowns (which are commissions on the sale of suits and shoes) by u and h.

The associate earned a commission of $47 the first week. That $47 represents the sum of the commission earned from selling suits and the commission earned from selling shoes.

We can represent this fact as follows:

3u + 1h = $47 (3 times the commission for selling 1 suit)

The appropriate equation describing the situation in the second week follows:

7u + 2h = $107

Now we have two linear equations in two unknowns, enough to enable us to calculate the commissions on selling suits and shoes.

3u + 1h = $47

7u + 2h = $107

We are to solve this system using the substitution method. The easiest approach here is to solve the first equation for h: h = $47 - 3u

and

then replace h in the second equation by $47 - 3u:

7u + 2($47 - 3u) = $107

Performing the indicated multiplication, we get 7u + $94 - 6u = $107

Simplifying this results in u + $94 = $107, and subtracting $94 from both sides reduces this equation to u = $13.

Thus, the commission on selling a suit is $13.

The commission on selling a pair of shoes is obtained from subbing $13 for u in the very first equation (3u + 1h = $47): 3($13) + h = $47. Subtracting $39 from both sides results in $8 = h. The commission on selling a pair of shoes is $8.

Find the value of c so that the polynomial p(x) is divisible by (x-3). p(x) =-x^3+cx^2-4x+3. c=?

Vilka [71]

Answer:

$\boxed{\textsf {The value of c is $\sf \dfrac{-14}{3}$. }}$

Step-by-step explanation:

A polynomial is given to us . We need to find the value of c so that it is divisible by (x-3 ) .The given polynomial to us is ,

$\sf \implies p(x)=- x^3+cx^2-4x+3$

And the factor is ,

$\sf \implies g(x) = x + 3$

Now , according to factor theorem , p(x) will be divisible by g(x) if p(-3) = 0

$\sf \implies p(x)= - x^3+cx^2-4x+3 \\\\\implies\sf p(-3) = 0 \\\\\sf\implies -(-3)^3+c(-3)^2-4(-3)+3 = 0 \\\\\sf\implies 27 + 9c +12+3=0 \\\\\sf\implies 9c +42=0 \\\\\sf\implies 9c = (-42) \\\\\sf\implies c = \dfrac{-42}{9}\\\\\sf\implies \boxed{\pink{\sf c = \dfrac{-14}{3}}}$

<h3>Hence the value of c is (-14)/3 .</h3>
