Answer:
the third one and the last one is correct
Step-by-step explanation:
we already know the second one is wrong because of it's set up.
just replace the points (-1,7) into each equation. if it doesn't work then move on to the next one. if it does work, then use that same equation except this time to the coordinates (2,4)
Answer: No
Step-by-step explanation:
Is 1/4 (8y -12) equivalent to 2y - 12? No. 1/4 (8y-12) equals out to 2y-3 not 2y-12. To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1

Answer:
2 3/4 years
Step-by-step explanation:
The interest is given by the formula ...
I = Prt . . . . . . principal P at annual rate r for t years
Solving for t gives ...
t = I/(Pr)
t = 4167.90/(16840×0.09) = 2.75
The duration of the loan is 2 3/4 years.

Answer:
0.75 cents
Step-by-step explanation:
You take...
$2.25 and subtract $1.50 to get 0.75 cents
In-depth...
Start off with taking a dollar away...
2.25 - 1.00 = 1.25
Then take off 0.50 cents...
We know that 0.50 cents are two 0.25 cents
So, we take off one 0.25 cent
1.25 - 25 = 1.00
Then the next 0.25 cents
*Remember: twenty-five (.25), fifty (.50), seventy-five (.75), a dollar (1.00)
<--- it is just adding 25 each time
If we subtract 0.25 cents from a dollar we get...
0.75 cents
