Answer:
The algebraic expression is 80d
Step-by-step explanation:
Maria's earnings per day = $80
Number of days= d
Total earnings for d days:
80d
Where,
80 is earnings per day
d is number of days
The algebraic expression is 80d
Algebraic equation is
y= 80d
Where
y= total income earned in d days
The expression is different from am equation because of the equal to sign(=)
Yes, angle B and angle D are equal, so it is true
<span>draw a straight line through those points. that's your line of reflection. now you have only to figure out which of those equations corresponds to it.
So it y=x</span>
