No solution bc if u multiply the bottom equation by -2, it makes 6x-8y=-4. This caused the x and y to eliminate, leaving 0=2.

During ski season,the owner of ski shop has determined that the number of customers in a day is greater then or equal to 50 more
Scilla [17]

The question is incomplete. Here is the complete question:

During ski season,the owner of ski shop has determined that the number of customers in a day is greater than or equal to 50 more then the temperature(Fahrenheit) . Write an inequality for the problem and determine the constraints on the variables.

Answer:

N\geq T+50

Step-by-step explanation:

Let the number of customers be 'N' and the temperature in Fahrenheit be 'T'.

Given:

Number of customers is related to temperature in Fahrenheit as:

Number of customers is greater than or equal to 50 more than the temperature in Fahrenheit. This means,

N\geq T+50

Now, since 'N' represents number of customers and number can never be a negative quantity. So, the only constraint for this inequality is that the number of customers must be greater than or equal to 0.

So, N\geq 0

Please help quick! <br> V=?
Stells [14]

Answer:

904.78

Step-by-step explanation:

we have the radius, which is 6.

were trying to find the volume.

the foemula for the v of a sphere is 4/3(pi)r^3

so, multiply 4/3 times pi and we get 4.18879.

find 6^3, which is 216. multiply tyese two values, and we get 904.77864.

so, the volume of this sphere is around 904.78

solve 3 square root of (x minus 4) plus 7 equals negative 14. please show your work. this is due sunday.
mestny [16]

Step-by-step explanation:

3√(x - 4) + 7 = -14

3√(x - 4) = -21 (subtract 7 from both sides)

√(x - 4) = -7 (divide 3 on both sides)

However √y is non-negative for all values of y in the domain of √y.

Hence there is no real solution for x.

The computers of six faculty members in a certain department are to be replaced. Two of the faculty members have selected laptop
Nadusha1986 [10]

Answer:

The answer is 0.067.

Step-by-step explanation:

Let the entire sample size be = s

Now there are 2 laptops in sample size, hence these can be chosen in one way only.

The required probability that both selected setups are for laptop computers can be found as:

p(two laptops)=\frac{s(two laptops)}{s}

= \frac{1}{15} or 0.067.

So, the probability is 0.067.
