Answer: the answer is 8
Step-by-step explanation:
The reason for this is because the dog is already a foot tall which is 12 inches. So 12+8=20
Note how all four answer choices begin with "x=-2(." This tells us that we have the graph of a horizontal parabola that opens to the left, because of the "-" symbol.
Given that the vertex is located at (-1,-3), we know that the (y-c) term must be (y-[-3]), or (y+3). Thus,we can immediately eliminate answer choices b and d
The only answer choice that fits this situation is (a): x = -2(y+3) - 1.
The system of equations that models the given situation is given as follows:
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given as follows:
- Variable x: Number of single lawns cut.
- Variable y: Number of front and back lawns cut.
He had 25 customers, hence:
x + y = 25.
He charges $15 for a single lawn and $25 for a front and back lawn, and made a total of $475, hence:
15x + 25y = 475

5v - 4/10 = 4/5
5v = 4/5 + 4/10 = 6/5
v = (6/5)/5 = 6/25
