Create an equivalent system of equations using the sum of the system and the first equation.

Answer:

B-

-5x + 4y = 8

-x + 5y = 10

Step-by-step explanation:

x+ 4y = 8, we'll call this A

4x + y = 2, we'll call this B

To create the equivalent system, you can mulitply or divide by a coeffecient, to get a pure solution. If you add or subtract, the system is unchanged.

We are adding A to B

x + 4y = 8 + 4x + y = 2

5x + 5y = 10, we'll call this C.

The new equation is the basis for the equivalent system, where C replaces B

Answer:

15.75

36

15.75

Step-by-step explanation:

Formula

the relationship between these two secants is NQ * NP = NM * LM

Givens

  • NP = 32
  • NQ = x
  • NM = 14
  • NL = 14 + 22 = 36

Solution

x*32 = 14*36                 Substitute values. Divide by 32

x = 14 * 36/32               Multiply 14 and 36    

x = 504/32                   Divide by 32

x = 15.75

The answer to the first box is 15.75 or x

The answer to the second box is

LM is assumed to be 22 So LN = MN + LM = 22 + 14= 36

QN = 15.75 is the third answer.
