7 0

Answer:

y = -2x + 7 and y = x - 2

Step-by-step explanation:

2x + y = 7

y = -2x +7

x - y = 2

-y = -x +2

y = x - 2

Which of the following can be added without altering any of the fractions?
Murrr4er [49]
<h3>Answer: Choice A</h3>

Why? Because the denominators are both the same at 2x+8. We can only add or subtract fractions when the denominators are the same. The general rule for adding fractions is

\frac{A}{C}+\frac{B}{C} = \frac{A+B}{C}

We have numerators A and B added together over a common denominator C. If we didn't have a common denominator, then we'd have to do a bit of algebraic manipulation to get both fractions to a common denominator. It doesn't have to be the lowest common denominator (LCD), though it's often more efficient that way.

Suppose the invertible function φ(x) has the domain (−5,11) and the range (−12,1).
Rom4ik [11]

Answer:

Range of \phi^{-1} is (−5,11).

Step-by-step explanation:

Given the invertible function Ф(x) which has the domain (−5,11) and the range (−12,1).

Invertible function is the function that inverses another function i.e if y=Ф(x) then x=g(y) where g is called the inverse of Ф and denoted by\phi^{-1}

Given Ф(x) the function whose domain is (−5,11) and range is (−12,1). Therefore, by definition of invertible function there exist a function g with domain (−12,1) and range (−5,11) which is called the inverse function denoted by \phi^{-1}

Hence, Range of \phi^{-1} is (−5,11)

Solve a 2 step linear equation algebraically. Show all work and all steps.
Solnce55 [7]

Answer:

1.) x = 4    2.) x = - 6

Step-by-step explanation:

1. 5x + 3 = 23

<em>Isolate the variable. Subtract 3 from both sides.</em>

5x = 20

<em>Divide both sides by 5.</em>

x = 4

____________

2. 42 = 18 - 4x

<em>Isolate the variable. Subtract 18 from both sides.</em>

24 = - 4x

<em>Divide both sides by -4.</em>

x = - 6
