The answer would be C. 3x + y = 5
Hey there!
Make the 2% to a decimal which is .02 and multiply it by 57 to find the sales tax
.02*57= 11.4
So 11.4 is the sales tax
So add 11.4 to 57 and you get
$68.40 is the total cost
Hope this helps!
Answer:
If f(x)=g(x), the solution is x=-2
Step-by-step explanation:
We are given:

We need to find the solution if f(x)=g(x)
Now solving for f(x)=g(x)

If f(x)=g(x), the solution is x=-2
I have no idea
I just need points for an answer sorry
X + y = 1.....multiply by -1
4x + y = -23
---------------
-x - y = -1 (result of multiplying by -1)
4x + y = -23
---------------add
3x = - 24
x = -24/3
x = -8 <====
x + y = 1
-8 + y = 1
y = 1 + 8
y = 9 <====
