WARRIOR [948]
He used 7 trays to hold all the marbles with equal number each tray. That means, there will be 16 marbles for each tray. Therefore, the number of marbles he will display on 3 trays would be a total of 48 marbles. Hope this answers the question. Have a nice day.

I need hellllppp plsssss​

Answer:

a_7=-15

Step-by-step explanation:

a_n  is given as the nth term of a sequence.

We want to find a_7 , which means we find the 7th term of the sequence.

Here, we simply substitute "7" into "n" of the formula given for  a_n  to find the value of the 7th term of the sequence.

We show this below:

a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15

So the 7th term is "-15"

Write an equation of the line that is parallel to -x + y = 5 and passes through the point (2,-5).
trasher [3.6K]

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

so convert the equation -x + y = 5 into slope intercept form by adding x to both sides

(-x + x) + y = 5 + x

0 + y = 5 + x

y = 5 + x

To match the slope intercept formula switch the x and 5 around

y = x + 5

If lines are parallel then they have the same slope (m) but they have different b

This means that the slope of the line will be 1 (in front of the x is an invisible 1 which would be m)

This is what we have so far...

y =  x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(2, -5)

-5 = 1(2) + b

-5 = 2 + b

-7 = b

y = x + (-7)

y = x - 7

Hope this helped!

Are the two expressions equivalent when x = 3?<br><br>8x + 40<br><br>5(2x + 8)​
Trava [24]
No because the first equation equals 64 when you solve it. But the second equation equals 70 when you solve it. So NO the two equations are not equal
