Answer:
Look at the explanation.
I'll be online so let me know if you still need help.
Step-by-step explanation.
A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.
The substitution is basically plugging in the y value to y = 8x + 10
If y = 2
and also y = 8x + 10
What do you think the substitution is?
Answer:
There is a constant rate of change of both money raised and distance, so the function is linear. But the variables do have a proportional relationship, and the graph includes the point (0, 0)—0 dollars will be raised by a person who runs 0 miles. So this is a proportional function.
Step-by-step explanation:
The answer is 45 because a object with 4 sides is equal to 360 degrees. If 45 is x you would add them together as 45+45+135+135=360
400 to 400-60 which is 340
Does this helps you?
I hope it does but tell me if it doesn't.
If this is a True or False question, that is true.
