PLEASE HELP ASAP!!! WILL GIVE BRAINLIEST!!! Test each statement below to see if it is reversible. If it is reversible, write it

as a true biconditional. If not, write not reversible.
1. If a whole number is a multiple of two, then the whole number is even.


2. Rabbits are animals that eat carrots.


3.Two lines that intersect to form four 90 degree angles are perpendicular.


4. Mammals are warm blooded animals.

Answer: 1. not revisable

2. not revisable  

3. Not reversible

4. not revisable

Step-by-step explanation:   1.Likewise, a number is a reversible multiple if the number formed by  2058 is not reversible because 8502/2058 = 4.131, which is not a whole number

2. When rabbits eat carrots you cannot form the carrot back to its original form so that's why its irreversible (not/non revisable)

3.If two perpendicular lines intersect, they form four 90* angles. ... whose sum measures to 90 degrees - The statement is not reversible

4. a few species of cold-blooded mammals exist but you cannot change a warm blooded animal into cold.

Which statement about proportional relationships is false? O A proportional relationship must graph as a line. O A graph of a pr
Zepler [3.9K]

Answer: Which statement is False

Step-by-step explanation:

proportional relationships

y ∝ x

=> y = kx    

Comparing with line line of equation

y = mx + c

m = k  , c = 0

Hence A proportional relationship must graph as a line

TRUE

at x = 0 , y = 0

Hence graph of a proportional relationship must pass through (0, 0).

TRUE

y = kx  

=> y/x = k  hence

Each point (or pair) in a proportional relationship must share the same ratio.

TRUE

Each point (or pair) in a proportional relationship must share the same difference.

FALSE

write an equation to represent the relationship, and find the amount of peanut butter used to make 25 cracker packages. the tabl
Nadusha1986 [10]

We are given 4 points.

(\frac{1}{2},2)

(\frac{5}{8},\frac{5}{2})

(\frac{3}{4},3)

(\frac{7}{8},\frac{7}{2})

Using this, we can make an equation.

y=4x

I got m=4 by using the slope formula.

m=\frac{2.5-2}{0.625-0.5}

m=\frac{0.5}{0.125}

m=4

So the equation we have is y=4x

Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for y, which is the number of cracker packages.

25=4x

x=\frac{25}{4}

We need to use \frac{25}{4} teaspoons of peanut butter to make 25 packages of crackers.

Hope this helps.

頑張って!

You use a garden hose to fill a wading pool. If the water level rises 11 centimeters every 6 minutes and you record the data poi
irina1246 [14]

Answer:

y=22\ cm

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x -----> the number of minutes

y ----> the water level in centimeters

In this problem we have a proportional relationship between the variables x and y

Find the value of k

For x=6 min, y=11 cm

k=11/6 -----> the slope is equal to the constant of proportionality k

The linear equation is

y=(11/6)x

so

For (12,y)

we have

x=12 min

substitute in the equation and solve for y

y=(11/6)12

y=22\ cm
