Jaquez earns money. The system of equations are 3m + 2.5n ≤ 8 and 50m + 65n ≥ 120.

Solution:

Given, Jaquez earns money by doing yard work.  

We have to write a system of inequalities that would help determine how many flowerbeds and lawns he could complete on a given day.  

Now, let the number of flower beds he could complete on a given day be m

And the number of lawns he could complete on a day be n.

Now, it takes her an average of 3 hours to pull weeds and an average of 2.5 hours to mow the lawn.  

She can work no more than 8 hours a day.  

Then, 3 x m + 2.5 x n ≤ 8 ⇒ 3m + 2.5n ≤ 8

And, She charges $50 to weed and $65 to mow the lawn.  

She needs to cover her expenses of $120 to make a profit.  

Then, 50 x m + 65 x n ≥ 120 ⇒ 50m + 65n ≥ 120.

Hence, the system of equations are 3m + 2.5n ≤ 8 and 50m + 65n ≥ 120

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
