Answer:
Option A is correct
reflection across the x-axis
Step-by-step explanation:
The rule for reflection across x-axis is given by:

As per the statement:
The coordinate of triangle ABC are:
A(−4,−3) , B(−7,1) and C(−1,−1).
The coordinate of triangle A'B'C' are:
From the given diagram we have;
A'(-4, 3), B'(-7, -1) and C'(-1, 1)
Apply the rule of reflection across x-axis on ABC we have;



Therefore, the reflection results in the transformation of △ABC to △A'B'C' is, reflection across the x-axis
Make the bottom number out of a hundered makes it easier to do the question.
make it 100 by mulitplying by 20 both bottom and top.
=40/100
then you put the number after the .
0,4
Question
Cable company A charges $45 a month for cable plus a $18 installation fee. Cable B charges $39 a month for cable plus a $30 fee for installation. Which inequality can be used to find out when the monthly cost for Cable company A is less than Cable company B?
a)39x+30<45x+18
b) 45x+18>39x+30
c) 45x+18<39x+30
d)39x+18<45x+30
Answer:
c) 45x+18<39x+30
Step-by-step explanation:
Step 1
We have to find the Algebraic expressions for the cable companies
Cable company A charges $45 a month for cable plus a $18 installation fee.
Let the number of months be represented as x
Hence, this is represented as:
$45 × x + $18
= 45x + 18
Cable B charges $39 a month for cable plus a $30 fee for installation.
Let the number of months be represented as x
Hence, this is represented as:
$39 × x + $30
= 39x + 30
The inequality that can be used to find out when the monthly cost for Cable company A is less than Cable company B?
= Cable company A < Cable company B
= 45x + 18 < 39x + 30
Therefore option c is correct
