Answer:
y=-x+3
Step-by-step explanation:
rise is 3 and the run is 3
So one easy way is to make the equation equal to only one place holder so
-7x-4y=16
add 7x to both sdies
-4y=16+7x
multiply both sides by -1
4y=-16-7x
divide both sides by 4
y=-4-7/4x
subsitute values for x and get values for y
exg
if x=0 then y=-4
if x=1 then y=-5 3/7
etc
Answer:
$25
Step-by-step explanation:
Multiply $20 by 0.25 (which is 25% as a decimal)
$20 x 0.25 = $5
Add $5 to $20 which makes the answer $25
The relevant rules of exponents are
.. (t^a)^b = t^(a·b)
.. t^a·t^b = t^(a+b)
You have
.. (t^-4)^-9·t^2
.. = t^((-4)*(-9) +2)
.. = t^38 . . . . . . . . . . . selection C
