Answer:

Slope intercept form is y = 2x-4

Step-by-step explanation:

Given equation: 2y + 2 = 4x - 6

The general form of slope intercept form is y = mx+c

2y + 2 = 4x - 6

2y = 4x - 6 -2

2y = 4x -8

dividing throughout by 2

y = 2x -4

Hence the slope intercept form is y = 2x -4

Four glasses of milk and 2 snack bars have a total of 72 carbohydrates (carbs), and 2 glasses of milk and 3 snack bars have a t

Travka [436]

One glass of milk has 11 carbs and one snack bar has 14 carbs.

Step-by-step explanation:

Let,

Glass of milk = x

Snack bar = y

According to given statement;

4x+2y=72 Eqn 1

2x+3y=64 Eqn 2

Multiplying Eqn 2 by 2

$2(2x+3y=64)\\4x+6y=128\ \ \ Eqn\ 3$

Subtracting Eqn 1 from Eqn 3

$(4x+6y)-(4x+2y)=128-72\\4x+6y-4x-2y=56\\4y=56$

Dividing both sides by 4

$\frac{4y}{4}=\frac{56}{4}\\y=14$

Putting y=14 in Eqn 1

$4x+2(14)=72\\4x+28=72\\4x=72-28\\4x=44$

Dividing both sides by 4

$\frac{4x}{4}=\frac{44}{4}\\x=11$

One glass of milk has 11 carbs and one snack bar has 14 carbs.

suppose a triangle has two sides of length 32 and 35, and that the angle between these two sides is 120. what is the length of t

Vesnalui [34]

Using cosine rule, the length of the required side = sqrt(32^2 + 35^2 - 2 x 32 x 35cos 120)
= sqrt(1024 + 1225 - (-1120))
= sqrt(2249 + 1120)
= sqrt(3369)
= 58.04

1) The minimum thickness of Saturns A ring is one-tenth kilometer. Write this decimal using a negative exponent.

yulyashka [42]

Answer:

1) $10^{-1}$

2) $2^{-2}$

3) $12^{-2}$

Step-by-step explanation:

Using negative exponent rule:

1) one -tenth of kilometer =.1 = $\frac{1}{10}=10^{-1}$

Using negative exponent rule:

2) $\frac{1}{4} =\frac{1}{2^{2} }=2^{-2}$

Using negative exponent rule:

3) $\frac{1}{144} =\frac{1}{12^{2} }= 12^{-2}$
