Applying the Properties Juan used the expression 16 - 9 - 12 + 22 to find his
profit for days 2 and 3. He rewrote the expression as 16
+(-9) + (-12) + 22.
Juan can use the associative and commutative
properties to rewrite the expression again. Explain why
he had to use the additive inverse before he could use
these properties

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

throw the computer

step-by-step explanation:

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
