The time t required to do a job varies inversely as the number of people working. It takes 5 hr for 3 cooks to prepare the food

miskamm [114]

Answer: It will take 1.875 hours

Step-by-step explanation:

Given that time t required to do a job varies inversely as the number of people working.

we have it expressed as

t∝1/N

where t is time required to do a job

N is the number of people working.

Introducing our constant of proportionality, we have tht

t=k1/N

t=k/N

Now since it takes 5 hr for 3 cooks to prepare the food , K becomes

t=k/N

5=K/3

K=5X3=15

Given that there are 8 cooks, time required to prepare dinner will be

t=k/N

t=15/8

t=1.875 hours

Using the graphing function on your calculator, find the solution to the system

stealth61 [152]

Answer:

It has infinite solutions.

D. More than 1 solution

Step-by-step explanation:

$\left \{ {{3y - 9x = -6} \atop {5y - 15x = -10}} \right.$

$\left \{ {{3y(-5) - 9x(-5) = -6(-5)} \atop {5y(3) - 15x(3) = -10(3)}} \right.$

$\left \{ {{-15y +45x = 30} \atop {15y - 45x = -30}} \right.$

$0+0=0$

or

$5y = 15x - 10\\y = 3x - 2$

$3(3x-2) - 9x = -6$

$0=0$

Which equation does the graph of the systems of equations solve? 2 linear graphs. They intersect at 0,3

Rainbow [258]

Answer:

D. $2x+3=-8x+3$

Step-by-step explanation:

We have been given a graph of system of linear equations and we are asked to choose the system of equations representing the given graph.

Upon looking at our graph we can see that our lines intersect at point (0,3). To find the system of equations represented in the graph we will substitute x=0 in our given equations and see which equation gives us an output of 3.

Let us start with 1st option.

A. $-2x+3=8x-3$

Upon substituting x=0 we will get

$-2*0+3=8*0-3$

$0+3=0-3$

$3\neq-3$

Since we get 3 on one side of equation and -3 on other side of equation, therefore, option A is not a correct choice.

B. $-2x+4=-8x+4$

Upon substituting x=0 we will get,

$-2*0+4=-8*0+4$

$0+4=0+4$

$4=4$

Since this system of equations intersect at point (0,4), therefore, option B is not a correct choice as well.

C. $2x+4=8x-4$

Upon substituting x=0 we will get,

$2*0+4=8*0-4$

$0+4=0-4$

$4\neq-4$

Therefore, option C is not a correct choice as well.

D. $2x+3=-8x+3$

Upon substituting x=0 we will get,

$2*0+3=-8*0+3$

$0+3=0+3$

$3=3$

Since this system of equations intersect at point (0,3), therefore, option D is the correct choice.
