Solve the system of equations 4x + 3y = -25 <br><br> 7x - 3y = -52
SIZIF [17.4K]

Answer:

x = -7

y = 1

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable x

[2] 7x = 3y - 52

[2] x = 3y/7 - 52/7

// Plug this in for variable x in equation [1]

[1] 4•(3y/7-52/7) + 3y = -25

[1] 33y/7 = 33/7

[1] 33y = 33

// Solve equation [1] for the variable y

[1] 33y = 33

[1] y = 1

// By now we know this much :

x = 3y/7-52/7

y = 1

// Use the y value to solve for x

x = (3/7)(1)-52/7 = -7

Solution :

{x,y} = {-7,1}

A package of 5 pairs of socks costs $35.95. What is the unit price of the pairs of socks?
Juliette [100K]

Answer:

7.19 a pair

Step-by-step explanation:

To find unit price divide the total by the amount

for ex

5 pairs cost 35.95 so 35.95 is the price of 5 pairs. To find out the price of 1 pair divide the price by the items or the 5 pairs of socks. 35.95 / 5 is 7.19

im sorry for my lack of knowing how to explain :(

2. If k is a constant, what is the value of k such that the polynomial k2x3 - 6kx+9 is divisible by x - 1?
marysya [2.9K]

Answer: The value of k =3.

Step-by-step explanation:

According to factor theorem, if g(x) =x-a is a factor of p(x) then p(a)=0.

Given: x-1 is a factor of k^2x^3-6kx+9.

then

k^2(1)^3-6k(1)+9=0\\\\\Rightarrow\ k^2-6k+9=0\\\\\Rightarrow\ k^2-3k-3k+9=0\\\\\Rightarrow\ k(k-3)-3(k-3)=0\\\\\Rightarrow\ (k-3)(k-3)=0\\\\\Rightarrow\ k=3

Hence, the value of k =3.
