Slope-intercept form:
y = m x + b
7 x - y = - 3
- y = - 7 x - 3 / * ( - 1 )( we have to multiply both sides of the equation by - 1 )
Answer:
y = 7 x + 3
The rule for multiplying similar bases with exponents:
(a^b)(a^c)=a^(b+c)
In this case we have:
(5^-2)(5^-1)
5^(-2-1)
5^(-3)
The rule for negative exponents:
a^(-b)=1/(a^b)
So in this case:
5^(-3) is equal to
1/(5^3)
1/125
Answer:
7.75
Step-by-step explanation:
1 mg = 0.001 g
31 mg * 0.001 = 0.31 grams per staple
0.31 g * 250 = 7.75 grams per 250 staples
