(08.03)A set of equations is given below:
2 answers:
Answer:
A. x+1= 4x+5
Step-by-step explanation:
To solve the set of equation we can use substitution method.
Here the given set of equations are
Equation A :
Equation B :
Now in substitution method we substitute y in terms of x from
first equation in to 2nd equation.
In other words we can also say that we equate both equations
so we have
or we can also say that
hence the correct option is option A

(C)
Explanation:
Congruence of these two angles directly implies p||q.
a) We kindly invite to check the image attached below to see a detailed graph of the <em>piecewise</em> function.
b) The <em>piecewise</em> function is continuous.
<h3>How to understand a piecewise function</h3>A <em>piecewise</em> function is a <em>conditional</em> combination of two or more functions, whose expression depends on which value of the domain is the function evaluated at.
a) The <em>piecewise</em> function described in the question is plotted on a graphing tool (i.e. <em>Desmos</em>), whose result is presented in the image attached below.
b) A function is <em>continuous</em> if and only if there is one value from range for every value of domain. The <em>piecewise</em> function is continuous as <em>linear</em> functions are continuous and the two functions of the <em>conditional</em> combination have the same value for x = 30.
