Answer:

no

Step-by-step explanation:

x+y=6

Substitute the point into the equation and see if it is true

-2 =6

This is not true so the point is not a solution

Answer: No

Step-by-step explanation:

To see if (0.-2) is a solution of x+y=6, we can plug it in and solve.

0+(-2)=6            [add]

-2≠6

Since -2 does not equal 6, we know that (0,-2) is not a solution.

saveliy_v [14]

Answer:

Price of Caleb's groceries before tax = $64

Step-by-step explanation:

Let the price of groceries before tax be =$ x

Sales tax charged = $1.60

Sales tax rate =2.5%

Sales tax charged in terms of x will be = 2.5% of the Original price of grocery =2.5\% of x = 0.025\times x=0.025x

So, we have,

0.025x=1.60

Dividing both sides by 0.025

\frac{0.025x}{0.025}=\frac{1.60}{0.025}

∴ x=64

∴ Price of Caleb's groceries before tax = $64
