the function f(x)=150+35x represents the amount of money a hotel charges( in dollars) for x nights including a $150 charge for p
Soloha48 [4]

For the 4 night at the hotel, the answer is 290 since you insert 4 in where the x should be 150+35(4). For the second question, the answer is 8 since you subtract the money you have (430) by the parking cost (150). This lead to 280 and you divide it by the amount you need to spent on hotel charge per night (35) and you get 8. That means that you can spend 8 night at the hotel.

Step-by-step explanation:

7. I believe it's independent because it makes sense and if it was dependent it wouldn't make senses.

8.For T you have 2 (Ts) so that give you a 2/8= 25% so you would basically make those Ts disappear and focus on 1 out of 6 and you'd get a 16.67% chance

9. 14.2857%

10. I don't understand ;-; am I suppose to multiply or see the chance if % it would get

The first system of equations has infinite solutions because you can write one equation as a linear combination of the other.The second system of equations has no solution because mathematically an incoherence results -14 = -2 / 7I attach the solutions for greater understanding.
x-4y=12; 5x-20y=60 --> infinitely many
y-7x=-14; 7y-49x=-2 --> none

Drag and drop the constant of proportionality into the box to match the table. If the table is not proportional, drag and drop "
olga_2 [115]

Answer: not proportional


Step-by-step explanation:

The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.

In the given table , let the variables are proportional then the constant of proportion(k)=\frac{y}{x}

\Rightarrow\ k=\frac{3}{2}=1.5

\Rightarrow\ k=\frac{7}{4}=1.45

⇒ k is not a constant of proportionality.

⇒ the variables x and y are not proportional.
