Answer:
Step-by-step explanation:
When you multiply two terms with same base, add the exponents.
Example: x*x² = x* x*x = x³
In short, x*x² = x¹⁺² = x³
54-48=6 so you need to find what percent 6 is of 48. 48 x 0.06= 2.88 so it increased by 2.88%
Answer:
y=1/3x + 5/3
Step-by-step explanation:
1-3/-2-4 = -2/-6 = 1/3
1/3 is the slope
1=-2(1/3) +b
1=-2/3 +b
5/3=b
