Answer:
T ≥ -2
Step-by-step explanation:
Given
Temperature = 2° below 0°
Required
Represent as an inequality
First, we need to calculate the temperature in the morning.
2° below 0 means.
Temperature = 0° - 2°
Temperature = -2°
Next, we determine the temperature at any time.
The question says the temperature continues to rise during the day.
Represent this with T
This means T will be greater than -2°
However, we need to consider where the temperature started from.
In other words, T = -2
Combine T = -2 and T = -2 together, we have:.
T ≥ -2
Hence, the inequality that represents the scenario is T ≥ -2
Answer:
3.45
Step-by-step explanation:
first you use a calculator.
The first you can multiply first equation by 2, you will get 16x - 12y = - 40, then add first equation to second
16x - 12y - 16x + 7y = - 40 + 30
-5y = - 10
Y= 2;
Then put y to first equation, because it easier.
8x - 2*6=-20
8x = - 8
X= - 1
Answer is x = - 1, y = 2.
12.93
Use inverse operations
9.27+3.66=12.93
I think it’s about 4.3 mph
