let x be the number of quarters, and y be the number of dimes.

we know that x + y = 29

then we are also given that

y = 5 + 3x

so we can solve for x and y:

plug y into the first equation:

x + 5 + 3x = 29

4x = 24

x = 6

and

y = 5 + 3*6 = 23

I have 6 quarters and 23 dimes

Which is the rate of change for the interval between 2 and 6 on the x-axis?

Answer:

Step-by-step explanation:

I think you misses attaching the photo, so please have a look at my photo for your better understanding.

We know the formula for rate of change of the parabola line:

$\frac{f(b)- f(a)}{b-a}$

Given here:

a= 2 => f(a) = 2

b=6 => f(b) = 2

Substitute all the values into the function, we have:

$\frac{14-2}{6-2} = 3$

So the rate of change is 3

Answer:

(3, 1)

Step-by-step explanation:

Let the coordinates of B be (x, y)

Since, M is the midpoint of AB.

Therefore, by mid point formula:

$1 = \frac{ - 1 + x}{2}, \: \: \: 3 = \frac{5 + y}{2} \\ \\ 2 = - 1 + x, \: \: \: 6 = 5 + y \\ \\ 2 + 1 = x, \: \: \: 6 - 5 = y \\ \\ 3 = x, \: \: \: 1 = y \\ \\ x = 3, \: \: \: y = 1 \\ \\ B = (3, \: \: 1)$

Add. 5/6 + 2 3/4 in simplest form.

Deffense [45]

okay so you would first turn everything into fractions 2 3/4= 11/4 + 5/6

next you would change the denominators so they match 11/4 x 6 = 66/24

5/6 x 4 = 20/24

so then you would add 66/24 + 20/24 = 88/24 = 11/3

11/3 is your answer

hope this helps!
