Answer:
Maggie's ballon is 12 high.
Step-by-step explanation:
We are asked to find the y-value, and the x-value is given:
Plug the values in to solve for y.
y = -(2)^2 + 17(2) - 42 y
= -(4) + 34 - 42 y
= -4 + 34 - 42 y
= -12
The negative sign tells the direction. It is negative because the ballon is in the opposite direction.
Answer:
The system has no solutions.
Step-by-step explanation:
Let's write it in a more traditional form

Try staring at it for a bit, and then realize what you are being asked: find two numbers whose difference is - at the same time, 7, and -7/6. That's impossible.
Same result you get by elimination. Multiply the first by 6 and either add or subtract - your choice the second. In either case you will get 0 = 35 or 0=49, which are obviously absurd
Answer:
3/10
Step-by-step explanation: you multiply 3 and 1/10
Answer:
12.5
Step-by-step explanation:
37.50÷15=2.5
2.5×5=12.5
Average rate of change is total change in y divided by total change in x...
r=(5-3)/(2--2)
r=2/4
r=1/2
