Answer:
B. Find reliable resources
Step-by-step explanation:
b. how long does it take you to jog around the park? it takes you minutes to jog around the park.
Answer:
Part a) The system of equations is
Part b) The number of minutes it takes you to jog around the park is
Step-by-step explanation:
Part a) Write a system of linear equations
Let
x-----> the number of minutes it takes you to jog around your block
y---> the number of minutes it takes you to jog around the park
we know that
----> equation A
----> equation B
Part b) How long does it take you to jog around the park?
Multiply equation A by -1 both sides
------> ----> equation C
Adds equation B and equation C
Find the value of x
Write the information as a system of linear equations: 2x + y = 10 and 2x + 3y = 22. Solving these equations, we find that it takes 6 minutes to jog around the park.
Given the information provided in the question, we first need to represent the given information through a system of linear equations. Following the instructions in the question, let x represent the time in minutes to jog around the block, and y represent the time in minutes to jog around the park.
From the given problem, we know:
To find how long it takes you to jog around the park (the value of y), we can use the method of substitution or elimination. In this case, let's use the method of substitution: we can start by solving the first equation for 2x, giving us 2x = 10 - y.
Substituting that into the second equation gives us 10 - y + 3y = 22, simplifying which leads to 2y = 12, and further simplification yields y = 6. Therefore, it takes you 6 minutes to jog around the park.

The correct statement regarding the operations with polynomials is given as follows:
C. (10x³ + 2x² - 11) + 9x² + 2x - 2 = 10x³ + 11x² + 2x - 13.
Like terms are terms that share these two features:
If two terms are like terms, then they can be either added or subtracted, that is, we can use them to simplify a polynomial.
Hence the polynomial that is correctly simplified in this problem is given as follows:
(10x³ + 2x² - 11) + 9x² + 2x - 2 = 10x³ + 2x² + 9x² + 2x - 11 - 3 = 10x³ + 11x² + 2x - 13.
Meaning that option C is the correct option in the context of this problem.

Answer:
The solution of the equation is 2.
Step-by-step explanation:
The given functions are
It is given that the graph of f(x) and g(x) intersects each other at (2,-1).
The given equation is
The solution of this equation is the value of x where both the functions are eqaul.
Since both functions are equal at x=2, therefore the solution of the equation is 2.
