{ y = 4 - x
   y = x - 4

Subsititute  y = x - 4

[ ( x - 4 )] = 4 - x ]

isolate x for ( x - 4 ) =  4  - x

x = 4

For y  = x - 4

Subsititute<span>  x = 4
</span>
y = 4 - 4

y = 0

Suppose you are going to graph the data in the table: Minutes Temperature (°C) 0 −2 1 1 2 3 3 4 4 5 5 −4 6 2 7 −3 What data shou
Gelneren [198K]

Answer:

See below

Step-by-step explanation:

Minutes            Temperature

 0                          -2

  1                           1

  2                          3

  3                          4

  4                          5

 5                           -4

 6                           2

  7                          -3

Minutes should be graphed on x - axis as it repeatedly increases by 1 and seems to be independent. (Remember the independent variable is on x-axis). The axis increment should be one as told before, that the terms are increasing by 1.

Now, Temperature should e graphed on y-axis because it seems to depend on Minutes. The axis increment should also be 1 for this as although, it not increasing by 1 but still at some points increases by 1. So, the axis increment should be 1 for Temperature.

18.<br> Place parentheses in the following equation to<br> make it true.<br> 4 + 53-8 = 19
soldier1979 [14.2K]

Answer:

(4+5)3-8 = 19

Step-by-step explanation:

1) You know that the parenthesis are going to go around 3-8 or 4+5 because that is the only way multiplication is involved. If you put them anywhere else it doesn't change the answer.

2) Try solving the problems (use PEMDAS)

(4+5)3-8 = 9*3-8 = 27-8 = 19

4+5(3-8) = 4+5(-5) = 4-25 = -21
