ANSWER
(–4.5, 4.25)
EXPLANATION
The first equation is
![y = - \frac{5}{2}x - 7](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B5%7D%7B2%7Dx%20-%207)
This function is in the slope-intercept form
The second equation is:
x + 2y = 4
2y =-x+ 4
![y = - \frac{1}{2}x + 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7Dx%20%2B%202)
The graph of the two functions are shown in the attachment.
The point of intersection represents the solution to the system of equations they represent.
The solution is
(–4.5, 4.25)
Multiply 21 by 6 to find <em>m</em>
Answer: m=126
The answer is: 4,8,6,5,2. Using the order of operations, which is PEMDAS, you can easily answer the question. Also, when finding the inverse of a function all you have to do is switch the places of x and y and then solve for y.
Answer:
D
Step-by-step explanation:
Given
x = 6 - x² ( subtract 6 - x² from both sides )
x² + x - 6 = 0 ← in standard form
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)
The factors are + 3 and - 2, since
- 3 × 2 = - 6 and 3 - 2 = + 1, thus
(x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 2 = 0 ⇒ x = 2
Sum of solutions = - 3 + 2 = - 1 → D
