Answer:
f(- 3) = - 5
Step-by-step explanation:
Given the point (- 3, - 5)
where x = - 3 is the input and y = - 5 is the output
The function can be represented by
y = f(x), that is
f(- 3) = - 5
3.2-5.7=-2.5 so its have to be a negative because a smaller number subtract a bigger number have to be equal to a negative number.
Answer: 64°C
Step-by-step explanation:
Official all-time high temperature = 43°C
Official all-time low temperature = –21°C
The difference between the two temperatures will be calculated by subtracting the low temperature from the high temperature. This will be:
= 43°C - (-21°C)
= 43°C + 21°C
= 64°C
(-7,3) here is the answer, easy one
Answer:
x = 34
Step-by-step explanation:
Angles are supplementary:
