Answers
Answer:
D) ΔABC ~ ΔFED
Step-by-step explanation:
Look at the little half-circles at the angles, A has cero, F too, C has one, D has one too, B has two, E has two too.
so A~F, B~E, C~D = ΔABC ~ ΔFED.

x= -1/5
Step-by-step explanation:
1
Add 9x9x to both sides.
x+9x=-2x+9x=−2
2
Simplify x+9xx+9x to 10x10x.
10x=-210x=−2
3
Divide both sides by 1010.
x=-\frac{2}{10}x=−102

Simplify \frac{2}{10}102 to \frac{1}{5}51.
x=-\frac{1}{5}x=−51
Addison works at a pet store. She worked less than 40 hours last week.
Create an inequality that represents the number of hours, n, Addison worked last week.
Answers
Answer:
Step-by-step explanation:
Let the number of hours she worked last week be n. If Addison worked less than 40 hours last week, this is expressed as:
n < 40 here < represents the less than sign. This means that Addison cannot work for any hour that is 40 and greater, she can only work for hours less than 40 e.g 39, 38hr etc.
The correct inequality expression is n< 40

♨Rage♨
Step-by-step Answer:
Whenever we have a problem like this, we can have 2 solutions (either one can work) because, in absolute equations, we need to find how far away the number is from 0.
So the answer would simply be that a>2 and a<-2
a can be anything greater than 2 or a can be anything less than 2

The table below shows the relationship between the number of cars sold and the amount of money earned by the car salesperson. Is the amount of money earned, in dollars, proportional to the number of cars sold?
Answers
Answer:
No, it is not proportional.
Step-by-step explanation:
This can be determined by looking at the first two items in the chart. I have looked at them all to find a certain pattern, but there wasn't any. The salesman earns $250 for one car sale, and he also earns $600 for two car sales, while this seems like it's just adding a $100 bonus, if you look at the third item on the chart adds a $200 bonus. You could be thinking that this is just adding a $100 bonus for how many cars were sold before, but then you move onto the fourth item on the chart. Which would give you $1,300 if the pattern was continued, yet instead the amount listed is $1,076.

Parallel or perpendicular
Lines 2 and 3
Lines 1 and 3
Lines 1 and 2
Answers
Answer:
Lines 2 and 3
Step-by-step explanation:
Lines 2 and 3 are parallel lines.
Lines 1 and 3 are perpendicular lines.
The lines 1 and 2 are perpendicular lines.
What are parallel lines?Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.
Given:
The photo shows an overhead view of airport runways.
Those lines that are perpendicular to each other that means create an angle of 90° at intersecting point are perpendicular lines.
Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.
From the diagram,
Lines 2 and 3 are parallel lines.
Lines 1 and 3 are perpendicular lines.
The lines 1 and 2 are perpendicular lines.
Therefore, lines 2 and 3 are parallel lines and lines 1 and 3 and lines 1 and 2 are perpendicular lines.

dai is comparing how many trading cards he has with his friend maura. initially they find that dai has four more cards than twice the number maura has
Answers
Answer:
B) [tex]2n+4[/tex]
Step-by-step explanation:
The question states that Dai has 4 more cards than twice the number of cards Maura has.
"more" - add
"twice" - multiply by 2
Let n be equal to the number of cards that Maura has.
Let D be equal to the number of cards that Dai has.
When we translate this into an equation, we would get something that looks like...
[tex]D=2n+4[/tex]
Since Dai has four more cards than twice the number of cards Maura has, 2 times the number of cards Maura has plus four is equal to the number of cards Dai has. Hopefully this is easier to understand written like an equation!
Therefore, the expression would be [tex]2n+4[/tex].
