Find the set of values of x for which y is zero inthe equation y=(x + 2) (2x-2)​

Mathematics
1 answer:
Alex777 [14]3 years ago
8 0

Answer:

{ - 2, 1 }

Step-by-step explanation:

To determine the values let y = 0, that is

(x + 2)(2x - 2) = 0 ← in standard form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x - 2 = 0 ⇒ 2x = 2 ⇒ x = 1

The set of values are { - 2, 1 }

S=L−rL<br><br> solve for r<br><br> Please solve this fast for much points.
podryga [215]
Subtract L from both sides. 
the expression now becomes,
<span>S−L=−rL</span>
2)Divide by L on both sides.
<span><span><span>S−L</span>L</span>=−r</span>
3)Multiply with a negative sign on both sides in the final step to obtain the expression in terms of r      so the answer is<span> #(L-S)/L = r#</span>

The graph of y = f(x) is graphed below. Wat is the end behavior of f(x)? <br> PLEASE ASAP
Maurinko [17]

Answer:

B.) as x --> -∞, f(x) --> ∞ and x --> ∞, f(x) --> ∞

Step-by-step explanation:

F(x) is another way of representing "y". That being said, the question is asking you the behavior of the graph in terms of the y-axis. On both sides of the function, there is an arrow pointing upwards, towards infinite, positive y-values. Therefore, as "x" approaches -∞ and ∞, f(x) is approaching ∞ (positive infinity).
