When using substitution to solve a system of equations , how can you tell when a system has no solution

If you have a false statement at the end.

Step-by-step explanation:

When using substitution to solve a system of equations, you can tell when the system has no solution if the equation at the end produces a false statement.

For example, at the end if you have something like 3x + 1 = 3x - 4. You would subtract 3x from both sides of the equation and be left with 1 = -4.

This is a false statement, 1 does NOT equal -4. Therefore, system of equations has no solution.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
