What’s the slope between (19,3) and (20,3)

Dmitriy789 [7]

0

The equation for slope is equal to
y - y
——-
x - x

so you’ll take

3-3 and divide it by 20-19

which would equal

0
—
1

and you know that 0 divided by anything is always going to equal 0

Can someone let me know if I simplified these equations correctly or at least show me how to do it?

Grace [21]

Answer:

Your work is correct as far as it goes. Now eliminate the terms that are zero.

Step-by-step explanation:

Multiplying anything by zero gives zero. Adding zero is like adding nothing. Zero is called the "additive identity element" because ...

a + 0 = a

Adding zero doesn't change anything. You can (and should) drop the zero if your goal is to simplify the expression.

$a. \quad x_{f}=v_{0}\\\\b. \quad x_{f}=v_{0}t\\\\c. \quad v_{f}^2=v_{0}^2$

gabby's piggy bank contains dimes and nickels worth $6.40. If she has 84 coins in all, how many of each does she have?

Sergeu [11.5K]

If we let Q be the number of quarters and N be number of nickels, this is the formula we would use:
[1] 25Q + 5N = 635 (using cents instead of dollars)

We also know something about Q and N.

[2] Q + N = 51

So multiply both sides of the second equation by 5. The reason we do this is because we're going to need to cancel out one of the variables (either Q or N) to solve for the other one. If we multiply times 5, we'll have 5N in both equations.
5Q + 5N = 255

Now we have two equations, and the second one can be subtracted from the first.

25Q + 5N = 635
-(5Q + 5N) = -255
---------------------
20Q = 380
so
Q = 19

There are 19 quarters.

And since there are 51 coins in all, 51-19 = 32 nickels.

Hannah's school hosted a book donation. There are 150 students at her school, and they donated a total of b books! Hannah donate

svetoff [14.1K]

Answer:

$x=3*\dfrac{b}{150}$

Step-by-step explanation:

Let x = number of books that Hannah donated

We know that the number of students is 150 and the total number of books is represented by b, we can write that as:

Average number of books donated by each student = $\dfrac{b}{150}$

Now we know that Hannah donated 3 times as much as the average. We can write that as:

$x=3*\dfrac{b}{150}$
