How to find when,<br>y=-1/3x - 3<br>​
Montano1993 [528]
The -3 would be where your line crosses the y-axis, so you would plot your point at -3. your slope will always be counted as rise/run, basically meaning you would count along the y-axis a certain amount of times, in this case -1, and along the x-axis a certain amount of times, here would be three. your next plot point would be (3,-4) and so on. hope this helped!

1. In a study on the likability of comedians, 10 participants observed one of two comedians (one who was humorous and one who wa
garri49 [273]

Answer:

a. 84 < n + (n + 2) + (n + 4) < 96

b. 26 < n < 30

step-by-step explanation:

using 'n' to represent the smallest even number, the next even number would be 'n + 2' and the next even number would be 'n + 4'. so, the expression to represent three consecutive even numbers is: n + (n + 2) + (n + 4).

since the sum of the these numbers needs to be between 84 and 96, we can set up the following inequality:

84 < n + (n + 2) + (n + 4) < 96

in order to solve for 'n', we must first combine like terms:

84 < 3n + 6 < 96

subtract 6 from all sides: 84 - 6 < 3n + 6 - 6 < 96 - 6 or 78 < 3n < 90

divide 3 by all sides: 78/3 < 3n/3 < 90/3 or 26 < n < 30.

nicole and adam are each saving money for a car. the total amount of money nicole will save is represented by the function f(x)=
Natalija [7]
They will have the same amount of money after 7 weeks.

We first set these equal to each other:
36+4x=x²+15

We want to gather all of the variables on one side.  Subtract 4x from both sides:
36+4x-4x=x²+15-4x
36=x²-4x+15

We want the equation to be equal to 0 to solve it, so subtract 36 from both sides:
36-36=x²-4x+15-36
0=x²-4x-21

We can factor this expression.  We want factors of -21 that sum to -4; -7(3)=-21 and -7+3=-4:
0=(x-7)(x+3)

Using the zero product property, we know that x-7=0 or x+3=0; this means x=7 or x=-3.  Since a negative number of weeks makes no sense, the answer is 7 weeks.
