Answer:
Paulo will need to mow at least 31 lawns to reach his goal of $2115.00.
Step-by-step explanation:
1. This is an inequality problem. The solution for this problem will involve creating in inequality to solve for the answer. To create an inequality, it is important to keep your information organized concisely.
Total = $2115.00
Lawn = $70.00
x = Amount of Lawns
2. From this information, the inequality can be formed.
70x 
2115
3. Using the order of operations, solve the inequality.
x 2215/70
x 30.21
4. The minimum number of lawns Paulo needs to mow is 31 lawns to meet his goal of $2115.00.

Answer:
see below
Step-by-step explanation:
3x^2 + 17x +10 =0
(3x+ ) ( x+ ) =0
We need to factor 10 = 2*5 or 1*10
They are positive since we have all positive terms
3*5 = 15+2 = 17
The 5 needs to multiply the 3 so it goes on the outside
(3x+ ) ( x+ 5 ) =0
That leaves the 2 on the inside
(3x+ 2 ) ( x+ 5 ) =0
Using the zero product property
3x+2 =0 x+5=0
3x = -2 x=-5
x = -2/3 x = -5
In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.
<em>Multiply -4 and -3 in the function above.</em>
<em>Add 3 on both sides of the equation.</em>
<em>Add 2y on both sides of the equation.</em>
<em>Divide both sides of the equation by -3.</em>
Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.
Answer:
f(-3) = -5
