larisa [96]

Answer:

y=12/x

Step-by-step explanation:

if y=12, and x=1 so

general formula y=12/x

for x=5 , y=12/5=2.4

you can graph by ploting points such as (1,12), (5, 2.4),...

the depth D, in inches, od wsnow in my yard t hours after it started snowing this morning is given by D=1.5t + 4. if the depth o

Blababa [14]

Answer:

8.5 inches

Step-by-step explanation:

First let's find the time t when the depth of the snow is 7 inches.

To do this, we just need to use the value of D = 7 then find the value of t:

$7 = 1.5t + 4$

$1.5t = 3$

$t = 2\ hours$

We want to find the depth of snow one hour from now, so we just need to use the value of t = 3 to calculate D:

$D = 1.5*3 + 4$

$D = 4.5 + 4 = 8.5\ inches$

The depth of snow one hour from now will be 8.5 inches.

What does 1/4 subtract 1/11 equal

Anastasy [175]

Answer:

7/44

Step-by-step explanation:

you can't simply subtract 1/11 from 1/4 because the denominators are not the same . Meaning you have to convert the denominators into a similar number. Transformers in even number and a consecutive number while 11 is an odd number and a prime number they don't really agree on anything 11 can only be divided by itself and 1 wall for can be divided by a multitude of things. Because of them not exactly agreeing on any specific category , you have to multiply them by each other . So your new fractions should look like 11 / 44 and 4 / 44 . from there you can easily subtract 4 from 11 and get 7 / 44 now normally you can reduce these types of fractions but because seven can only be divided by itself and 44 is not a factor of 7 you cannot reduce this fraction .

The slope-intercept equation is y=mx+b.

The slope formula is $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Our three points are (5,5), (-5,-7) and (0,-1)

Using our slope formula our slope becomes $\frac{-7-5}{-5-5} =\frac{12}{10} =\frac{6}{5}$

Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, $y=\frac{6}{5}x-1$ . When we solve for x and y, we get -1=0+b, or b=-1.

When we plug that back into the equation, we get $y=\frac{6}{5}x-1$ .
