Hello,
The translation t is (x,y)->(x-2,y+3)
So its inverse t^(-1)=-t is (x,y)->(x+2,y-3)
B=-t(B')=(4+2,-8-3)=(6,-11)
Probably d because i don’t think it can be C
First: Multiply the measurements.
• 7.8 x 12.8 = 99.84
Second: Divide by 2.
• 99.84/2 = 49.92
Answer: 20
Step-by-step explanation:
Answer:
The difference in these temperature extremes in Africa is: 147 °F
Step-by-step explanation:
As per the statement:
The highest temperature ever recorded in Africa was 136°F in Libya.
⇒Highest temperature = 136 °F
It is also given that:
The lowest temperature ever recorded in Africa was –11°F in Morocco.
⇒Lowest temperature = -11 °F
We have to find the difference in these temperature extremes.

Substitute the value we have;
= 136-(-11) = 136+11=147°F
Therefore, the difference in these temperature extremes in Africa is: 147 °F
