Solve the system by the substitution method.
Ghella [55]

Answer:

A) The solution set is (6,-8).

Step-by-step explanation:

3x - y = 26

-3x       - 3x        Subtract 3x from both sides

-y = -3x + 26     Divide both sides by -1

y = 3x - 26

Now plug this into 7x + 8y = -22 to solve for x

7x + 8(3x - 26) = -22        Distribute

7x + 24x - 208 = -22       Combine like terms

31x - 208 = -22

     + 208    + 208            Add 208 to both sides

31x = 186                           Divide both sides by 31

x  = 6

Plug this into y = 3x - 26 to solve for y

y = 3(6) - 26           Multiply

y = 18 - 26              Subtract

y = -8

In what ways does adding a constant or coefficient to a quadratic equation affect the graph?
erastova [34]
<span>If you are adding a constant, then the graph is either raised or lowered k units.

For example.... If you have the graph of y = x^2 and now you add 3, so your new graph of x^2 + 3, will be the same graph as x^2 but raised vertically 3 units.
 
The graph of x^2 - 7 will be the graph of x^2 lowered vertically 7 units.


I hope my answer has come to your help. God bless and have a nice day ahead!</span>

What is 2.16 repeated as a decimal
Zarrin [17]
Ok, so what we want to do here is first remove the repeating decimal.

x=2.16 repeating
10x=21.6 repeating
100x=216.6 repeating

Subtract 10x=21.6 repeating from 100x=216.6 repeating. This will get rid of the repeating numbers.

100x=216.6 repeating
-10x=21.6 repeating
__________________
90x=195

Divide both sides by 90.

x=195/90

Now you can simplify that into 13/6.
