Answer:

x= -1/5

Step-by-step explanation:

Divide both sides by 1010.

x=-\frac{2}{10}x=−102

I have to do what the image below says but I don't know how to write it:,)

Answers

Answer:

To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y-intercept--this should be of the form (0, b). The y- coordinate is the value of b in the equation.

♨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

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].

I hope this helps!

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.
