Answer:
4x=8
Step-by-step explanation:
4x=32
32/4=8
Answer:
Step-by-step explanation:
As per Newton law of cooling we have temperature of a cooling object at time t is given by
T(t) = 
where 
When t=2.5, we have
Hence equation is
Using this we find that
i.e. At 1.6 seconds the coffee will reach a temperature of 130 degrees
Answer: A
You already know that the y-intercept in -32 for every equation by plugging in 0 for x, so disregard the coordinate (0,-32). Plug in -2 and 4 as your x values and check if they are equal to your y-value 0.
Answer:
456
Step-by-step explanation:
1 dollar equals 10 dimes.
So $45.60 would equal 456 dimes
Answer:
No Solution
Step-by-step explanation:
4x-2y=8
y=2x+1
Make the first equation into where it says y=.
-2y=-4x+8
y=2x-4
Substitute either equation into the other as y=.
2x+1=2x-4 or 2x-4=2x+1
Switch terms around so they're with their like terms. Make sure it becomes the opposite when switching.
2x-2x=-1-4 or 2x-2x=4+1
0=-5 0=5
Since x did not come back to equal an answer, this problem is not workable. There is no solution to it. If you were to do it a different way, there still would not be a solution to it.
