Answer:
Step-by-step explanation:
Squaring a^(-2) results in a^(-4).
Squaring 8^7 results in 8^14.
Putting these factors together, we get
8^14
------- this is equivalent to Answer C.
a^4
Answer:
x=-4 and y=10
Step-by-step explanation:
Use the second equation to make y=x+6
sub y=x+6 into the first equation
-x-2*(x+6)=0
-x-2x-12=0
-3x-12=0
3x=-12
x=-4
Now sub x=-4 into the second equation
-(-4)+y=6
y=6+4
y=10
Answer:
A because its supposed to be on the y axis
Answer:
15°C
Step-by-step explanation:
Find the difference by subtracting -4.8 from 10.2
10.2 - (-4.8)
Subtracting a negative number changes to adding a positive number:
10.2 + 4.8
= 15
So, the difference in temperature between the two cities is 15°C
