Answer:

26. t<-70 see description below.

Step-by-step explanation:

To solve an inequality in one variable, solve using inverse operations like any other equations. However, if dividing or multiplying by a negative at any points, flip the sign of the inequality.


Example:

\frac{t}{-7}>10\\\\ -7*\frac{t}{-7} >10*-7\\\\t

-7 was multiplied to as an inverse operation to division by -7. Because it was negative, the inequality sign was flipped. To graph, plot -70 on the number line with an open circle. Then draw an arrow from -70 to the left.

At the moment a hot iron rod is plunged into freezing water, the difference between the rod's and the water's temperatures is 10
Papessa [141]

Answer:

D(t)=100(0.4)^t

Step-by-step explanation:

The temp is 100 at time t = 0

After 1 sec, the temp difference would be:

100-(\frac{100-60}{100})

After 2 sec, the temp difference would be:

100-(\frac{100-60}{100})^2

Similarly for 3 seconds, 4 seconds etc.

We notice that the parenthesis part is 40% of it, so we can also write:

100(40%)^t,

where

t is the time

40% can be written as 40/100  = 0.4

SO, the function is:

d(t)=100(0.4)^t

x represnts the number of t-shirts and y represents the price

x = 1 y = 9

x = 2 y = 16

x = 3 y = 24

etc.

Step-by-step explanation:

This is not propational relationship because if it was putten on a graph it would not make a striaght line. The quantities do not have a propational relationship because for it can be a propational relationship you have to divide or multiply, you have to have a striaght line, and it has to go through the origin (0,0)
