Answer:
The slope of the line is -5
I might be wrong but I think it's 504
I got this by multiplying 28 and 18 hope it helped : )
You need a common denominator of 6 because it's the least common denominator of 2 and 3. So you can change -1/2 to -3/6. And change 2/3 to 4/6. The new equation would be -3/6 + 4/6 = 1/6.
( 3 x 10^9 ) x ( 2 x 10^17 ) = 6 x 10 ^ 26
Don’t listen to the other person the answer is C.
x+x+x+x would be 4x. x^4 would be 4 times 4 times 4 times 4.
