Answer

solve for y;

The answer is y= -(1/3)x-3/2

Step 1. 6y=-3x-9

Stept 2. 6y/6=(-3x-9)/6 ==> y=-(3/6)x-9/6

Step 3. y=-(1/3)x-3/2 Simplify

Step-by-step explanation:

Step 1. Write out the equation in the problem

Step 2. Solve for y by dividing both sides of the equation by 6

Step 3. Once the you have divided both sides of the equation by 6, simplify it.

In 4 hours, an experienced cook prepares enough pies to supply a local restaurant's daily order. Another cook prepares the sam

vodka [1.7K]

Answer:

$9\frac{1}{3}hours$

Step-by-step explanation:

Let third cook take x hours to prepare the same number of pies y alone

Let y be the number of pies

In 1 hour ,third cook prepare pies= $\frac{y}{x}$

One experienced cook takes time to prepare enough pies =4 hours

In 1 hour , cook prepare pies= $\frac{y}{4}$

Another cook takes time to prepare same number of pies =7 hours

In 1 hour , another cook prepare pies= $\frac{y}{7}$

All three cooks take time to prepare the same number of pies=2 hours

In 1 hour,all three cooks prepare pies= $\frac{y}{2}$

According to question

$\frac{y}{4}+\frac{y}{7}+\frac{y}{x}=\frac{y}{2}$

$y(\frac{1}{4}+\frac{1}{7}+\frac{1}{x})=\frac{y}{2}$

$\frac{1}{4}+\frac{1}{7}+\frac{1}{x}=\frac{1}{2}$

$\frac{1}{x}=\frac{1}{2}-\frac{1}{4}-\frac{1}{7}$

$\frac{1}{x}=\frac{14-7-4}{28}=\frac{3}{28}$

$x=\frac{28}{3}=9\frac{1}{3}$ hours

Hence, the third cook takes time to prepare the same number of pies alone= $9\frac{1}{3}hours$

Hope this helps. Mark me brianest please... Anna ♥

Step-by-step explanation:

Answer: -40 < T < 140

From the question, we are informed that the gas that the driver uses freezes at −40° F and evaporates at 140° F.

To get the inequality to represent the temperatures at which the gas in the truck will remain in liquid form, we should note that the temperature will be lower than 140°F but more than -40°F. This can be expressed as:

= -40 < T < 140

Answer:

Step-by-step explanation:

$y=-x^{2} -5x-6$

$y=-(x^2+5x+6)$

$y=-(x+3)(x+2)$

Set each factors equal to zero.

$(x+3)=0 , x=-3$

$x+2=0 , x=-2$

The x-int is

$(-2,0)$

5. Using the factor tree, What are the prime factors of 36

alex41 [277]

Answer:

Step-by-step explanation:

A factor tree is not unique for a given number. Instead of expressing 36 as 2 × 18, we can express 36 as 6 × 6. Prime factorization of 36 using factor tree method is 2 × 2 × 3 × 3 = 2² × 3².
