aron is reading a graph of equivalent ratios. If one of the ratios is represented as (6, 2), which could be another ratio? (1, 3
Usimov [2.4K]

Answer

(3,1)

Explanation

(6,2) is the same as (3,1) because the x value and y value are proportional, meaning you multiplied or divided both the x value and y value by the same number.

6 divided by 2 is 3.

2 divided by 2 is 1.

(1,3) doesn't work because the x value and y value are switched.

6 divided by 6 is 1.

2 divided by 6 is not 3.

(8,12) doesn't work because the x value and y value are switched... and it wouldn't work anyways.

6 divided by 3/4 is 8.

2 divided by 3/4 is not 2.

(12,8) doesn't work because the x value and y value aren't proportional.

12 divided by 2 is 6.

8 divided by 2 is not 6.

Therefore only (3,1) could be another ratio to (6,2).

Please help giving brainiest explain
oee [108]

Answer:

Slope: -2/3

Y-intercept: (0, 9)

Equation: y = -x + 9

3 blocks away: 6 visits

Step-by-step explanation:

Calculate slope from point (1, 8) to point (3, 7) on the line.

The y-intercept is where the line meets the y-axis.

The equation took a bit of guessing, but the -x is the y = x line, but reversed. 9 is the y-intercept.

Check the point on the line where x = 3.

Hope this helps!

Sally has read one-third of her book. She finishes the book by reading the same amount each night for 5 nights. Part A. What fra
boyakko [2]

Answer:

2/15

Step-by-step explanation:

Given that she have already read one-third of the book.

The fraction f of the book that will remain is;

f = 1 - 1/3 = 2/3

Then she finishes the book by reading the same amount each night for 5 nights

That implies she reads the remaining 2/3 of the book at equal rates for 5 nights.

Let x represent the fraction rate read per night;

5x = 2/3

Divide both sides by 5

x = 2/3 × 1/5

x = 2/15

Therefore, she reads 2/15 of the book every night for 5 nights.

Construct a truth table for proposition (¬p)\rightarrowq
Sergio [31]

Answer:

\left[\begin{array}{ccc}(-p)&--->&q\\f&t&t\\f&t&t\\t&t&f\\t&f&f\end{array}\right]

Step-by-step explanation:

First, we find all the possibilities for p and q in a table:

p  q

t    t

t    f

f    t

f    f

then -p:

-p  q

f    t

f    f

t    t

t    f

and we apply the operator --> (rightarrow), that is only f (false) y if the first one is t (true) and the second one is f (false)

-p    --->    q

f       t       t

f       t       f

t       t       t

t       f       f
