The temperature one morning in Shasta was LaTeX: -12^\circ F− 12 ∘ F. By the afternoon, the temperature had risen LaTeX: 8^\circ
Vlad [161]

Answer:

The Temperature in the afternoon was -4\° F.

Step-by-step explanation:

Given:

Temperature in the morning = -12\° F

Rise in temperature = 8\° F

We need to find the temperature in the afternoon.

Solution:

Now we know that;

temperature in the afternoon is equal to Temperature in the morning plus Rise in temperature in afternoon.

framing in equation form we get;

temperature in the afternoon = -12\° F+8\° F=-4\° F

Hence the Temperature in the afternoon was -4\° F.

Answer:

  see below

Step-by-step explanation:

The third table shows a relationship of y=2x.

Essentially, you have to see whether the value of y/x is constant for all the values in a table. If it is not, then the relation is not proportional.

  in the first table, -4/-2 ≠ -3/-1

  in the second table, -4/-2 ≠ 3/1

  in the fourth table, -4/-2 ≠ 6/2
