Line $j$ is perpendicular to $\frac{y}{3}+\frac{2x}{5}=2$. What is the slope of line $j$?

Step-by-step explanation:

The slope of is -3. When a line is perpendicular to another, it's slope will be the negative reciprocal of the other line. -3 could also be written as , and if you take the reciprocal, it would be , and the negative form of this (since a negative plus a negative is a positive) would be .

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
