Answer:
The range is { 7,8}
Step-by-step explanation:
The range of the functions is the output values
We do not list the repeated values more than one and normally list them from smallest to largest
The range is { 7,8}
m = t2.5
So money equals to tickets sold*2.5
2.5 is each tickets price
If you ask how I found;
$100 / 40 tickets = $2.5
Answer:
175%
Step-by-step explanation:
1 would be 100%
3/4 would be 75%
100%+75%=175%
Yes, parallelogram congruent angles theorem
Set up the following equations:
x represents car A's speed, and y represents car B's speed.
We'll use elimination to solve this system of equations. Multiply the first equation by 7:
Combine both equations:
Divide both sides by 28 to get x by itself:
The speed of car A is
80 mph.Since we now know the value of one of the variables, we can plug it into the first equation:
Subtract 160 from both sides.
Divide both sides by 2 to get y by itself:
The speed of car B is
60 mph.
