Answer:
[26, -32]
Step-by-step explanation:
7[-y - 6] + 6y = -10
-7y - 42 + 6y = -10
-y - 42 = -10
+ 42 + 42
____________
-y = 32
-32 = y [Plug this back into both equations to get the x-value of 26]; 26 = x

Answer:
There will be $4450 left at the end of the year.
Step-by-step explanation:
We first take 11% and multiply it by $5,000. We get 550. This means that the account will lose $550. Next, we take our original amount, $5,000, and subtract $550 from it. We will get $4450.

Answer:
c. x = 7-t; y = -1/(t -7)
Step-by-step explanation:
To find the parametric equation for x, use the equation for t and solve for x.
t = 7-x
x = 7 -t . . . . . . add x-t to both sides
__
To find the parametric equation for y, substitute the equation for x.
y = 1/x
y = 1/(7-t)
To make this match the available choices, we need to multiply numerator and denominator by -1.
y = -1/(t -7)
The parametric equations are ...
x = 7 -t; y = -1/(t -7) . . . . . . matches choice C
