  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

-x + 4y = -8

-5x - 4y = -16

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine equations:                     -6x = -24
  2. Isolate <em>x</em>:                                        x = 4

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                   -x + 4y = -8
  2. Substitute in <em>x</em>:                      -4 + 4y = -8
  3. Isolate <em>y</em> term:                       4y = -4
  4. Isolate <em>y</em>:                                y = -1

ASAP! A company makes a profit from selling yo-yos at their store. Each yo-yo sells for $8.00 and they must also pay a store cle
dusya [7]

Answer:

The equation that describes the profit the store makes in a day that X units of yo-yo is sold is  P= X × $8.00 - $50.00

Step-by-step explanation:

The information given are;

The price of each yo-yo = $8.00

The only available cost is the store clerk fee cost per day = $50.00

Let us call the number of yo-yo's sold per day as X

Therefore, the amount sold per day = X × $8.00

The company's profit, P = Total sales - Total cost

∴ P= X × $8.00 - $50.00

Therefore, the equation that describes the profit the store makes in a day that X units of yo-yo is sold = P= X × $8.00 - $50.00.

Given right triangle A w/a hypotenuse length of x+4 and a leg of x, and right triangle B, w/ a hypotense length of 3y and a leg
alex41 [277]

Answer:

Value is x=8 and y=4

Step-by-step explanation:

Given : A right triangle 'A'  hypotenuse length of x+4 and a leg of x,

and right triangle 'B' hypotenuse length of 3y and a leg length of y+4

To find : For what values of x and y are the triangles congruent by HL?  

Solution :

Triangle A,

Hypotenuse: x+4

Leg: x

Triangle B,  

Hypotenuse: 3y

Leg: y+4  

Since the triangle A and B are congruent so, the sides of triangles are equal.

x+4=3y    (Hypotenuse are equal)  ..........[1]

and x=y+4   (Legs are equal)   ..........[2]

Solving the equation of system,

Put the value of x from [2] in [1],

x+4=3y

y+4+4=3y

8=2y

y=4

Substitute y in [2],

x=y+4

x=4+4

x=8

Therefore, The value of x=8 and y=4

Verifying for the values of x and y:

Triangle A,

Hypotenuse: x+4=8+4=12

Leg: x=8

Triangle B,  

Hypotenuse: 3y=3(4)=12

Leg: y+4=4+4=8

Both hypotenuses and both legs are equal hence they are congruent.
