Answer:

y = - \frac{1}{2}

Step-by-step explanation:

Given

\frac{3}{4y+2}

The denominator of the expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that y cannot be, that is

4y + 2 = 0 ( subtract 2 from both sides )

4y = - 2 ( divide both sides by 4 )

y = \frac{-2}{4} = - \frac{1}{2} ← excluded value

Can someone tell me if i did this right? im also not sure which one is the scale factor.
PIT_PIT [208]
If you are moving the center of circle 2 to the the center of circle 1, then the translation rule is (x,y) ---> (x+4, y+10). 
Note how x = 1 turns into x = 5. So we add 4
Also, y = -2 turns into y = 8. We add 10

The scale factor to turn the radius r = 4 into r = 8 is 2. Basically we double the radius. We can divide the two radii to see 8/4 = 2

----------------------------------

Summary:
To go from circle 2 to circle 1, we apply these two transformations
translation: (x,y) ---> (x+4, y+10)
dilation: scale factor 2

note: 
if you want to go backwards, go from circle 1 to circle 2, then undo the transformations above

A cable car begins its trip by moving up a hill. As it moves up, it gains elevation at a constant rate of 50 feet/minute until i
asambeis [7]

Answer:

he cable car's elevation will be 750 feet after 15 minutes

Step-by-step explanation:

Given:

elevation, e =2,000 feet

rate, I = 50 feet/minute

The equation that models the car's elevation, e, after t minutes is e = |t

The cable car's elevation will be 750 feet after how many minutes?

since, e = It

for 2,000 feet = 50 feet/minute  * t

t = 2000/50 =40minutes

using the same constant rate, I for 750ft, T =

since, e = It

for 750 feet = 50 feet/minute  * t

t = 750/50 =15minutes

11 less than 7 times a number is 5 more than 6 times the number. find the number.
kolezko [41]

Let's translate the words into expressions:

11 less than 7 times a number is 7x-11

5 more than 6 times the number is 6x+5

So we have the equation

7x-11 = 6x+5

Subtract 6x from both sides:

x - 11 = 5

Add 11 to both sides:

x=16

If shamans has 3&1/3 cups of flour to make cupcakes. If she needs 1/13 cup of flour to make one cupcake how many full cupcak
Kobotan [32]

Answer:

43.3 cupcakes

Step-by-step explanation:

If shamans has 3&1/3 cups of flour to make cupcakes. If she needs 1/13 cup of flour to make one cupcake how many full cupcakes can she make

From the above question

1/ 13 cup = 1 cup cake

3 1/3 cups = x

Cross Multiply

1 /13 × X = 3 1/3 × 1

x = 10/3 ÷ 1 /13

x = 10/3 × 13/1

x = 130/3

x = 43.333333333 cupcakes
