Answer:
x + y = 4 or y = -x + 4
Step-by-step explanation:
0 = -1[4] + b
4 = b
y = -x + 4
If you want it in <em>Standard</em><em> </em><em>Form</em>:
y = -x + 4
+x +x
_________
x + y = 4 >> Line in Standard Form
* Since the <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] is -1 and that parallel lines have SIMILAR SLOPES, -1 remains the same.

Answer:
2s + 30 = 2s
Step-by-step explanation:
Time up hill + time down hill = total time
:
Multiply equation by 30s; results
2s + 30 = 2s

If you are doing a quadratic, you wil have to do quadratic formula, if you are just doing that, no solution.
We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the following exponential function:
where y represents the car's value and t represents time in years. We are asked to find the decay rate as a percentage.
We know that an exponential decay function is in form
, where,
y = Final value,
a = Initial value,
r = Decay rate in decimal form,
x = time.
Upon comparing our given function
with standard decay function
, we can see that
.
Let us solve for r.



Let us convert 0.24 into percentage.

Therefore, the decay rate is 24%.
