The mass of an average grain a table salt in a sample is 3×10‐⁴ grams, and the mass of an average grain of rock salt in sample is 1.2×10‐²grams. Using the property of exponents, what do you need to multiply 10-² by to get 10-⁴

the first one, all those points on the line just make a strait line.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
