I'm pretty sure it's d
Step-by-step explanation:
20 percent is the discount. Everything has 100%, so if you take away 20% of the 68$ you will get only the amount of the discount; however, we are looking for the price after the discount. Since 20% is the discount, then perhaps 80% is the cost after the discount is used; therefore, if you multiply .8 which is equal to 80% to 68, you will get the cost after the discount. The answer would be .8(68)=T

Answer:
Option C is correct.
System of equation which will produce infinitely many solutions:
3x - y = 14
-9x +3y = -42
Step-by-step explanation:
From the options
Only equation which is infinitely many solutions is
3x - y = 14 ......[1]
-9x +3y = -42 ......[2]
For infinitely many solutions, we are looking for linearly dependent equations, which means one equation is an exact multiple or sub-multiple of the other.
Multiply [1] by -3 we get
or
-9x + 3y = -42 which is same equation as [2]
therefore. by definition of infinitely many solution,
equation 2 is -3 times(or multiple) of equation 1
The answer is SAS
Hope this helps......
