Answer:
Option C, 6.5
Step-by-step explanation:
<u>Step 1: Substitute y in the equation 3x - 5y = 22</u>
3x - 5y = 22
3x - 5(-5x + 32) = 22
3x + 25x - 160 + 160 = 22 + 160
28x / 28 = 182 / 28
x = 6.5
Answer: Option C, 6.5
Answer:
Input
Independent variable
Step-by-step explanation:
we know that
<u>Independent variables</u>, are the values that can be changed or controlled in a given model or equation
<u>Dependent variables</u>, are the values that result from the independent variables
we have the function
In this problem
This is a proportional relationship between the variables d and t
The function d(t) represent the dependent variable or the output
The variable t represent the independent variable or input
I think You should break it down to the First and third One because of
Answer:
(b) (x -10)(x +10)
Step-by-step explanation:
The factorization of the difference of squares is a special form:
a² -b² = (a -b)(a +b)
<h3>Application</h3>
Your expression is recognizable as the difference of squares:
x² -100 = x -10²
Using the above form, the factorization is ...
= (x -10)(x +10) . . . . . . . . matches the second choice
