Answer:
36
Step-by-step explanation:
21/9=84/x
x=84(9/21)
x=36
you add both the mixed numbers, which out be 5 2/3 so c.
The value of (-2)4 = -8
The value of (-2)^2 (4)= 16

Answer:
T-intercept = 67
Step-by-step explanation:
Given
T = 44m + 67
Required
Calculate and interpret the t-intercept
To calculate the t-intercept, we simply set the number of minutes (m) to 0
i.e. substitute 0 for m in T = 44m + 67
T = 44 * 0 + 67
T = 0 + 67
T = 67
Hence, the T-intercept is 67
The interpretation is that the initial temperature when the oven is turned on is 67 degrees
