17%

Step-by-step explanation:

change in temprature=100-120=-20

% chsnge in temp.=-20/120 ×100=-50/3 %=-16.66666...≈-17%

negative sign shows temperature is coming down.

Answer:

Solution : Graph 4

Step-by-step explanation:

Let's break down this function,

{ y = 5 if x ≤ - 2, y = 0 if x = 3, y = - 1 if x > 3 }

As you can see, graph 4 is the only one that represents this.

• When y = 5, x  ≤ - 2. This is represented by a ray with a colored hole, indicating that x = - 2. At the same time this ray extends infinitely in the negative direction, indicating that x < - 2.

• When y = 0, x = 3. This is represented as the point ( 3, 0 ).

• And when y = - 1, x > 3. At y = - 1 another respective ray, that has a non - filled hole, indicates that x ≠ 3. The ray extends infinitely in the positive direction, meeting the criteria that x > 3.

A family goes on a long car trip. The number of miles, y, they have left to drive is given by the equation y=510−60x, where x re
Korvikt [17]

Answer:

0,1.5

Step-by-step explanation:

y = 510 - 60x

We want to find the domain or the x values where x represents the time

We need to determine the possible values for x

Y cannot be greater than 510 or less than 0.  510 means they have not started the trip, and 0 means they have arrived

510 = 510 -60x

Subtract 510 from each side

510-510 = 60x

0 = 60x

The smallest value of x can be 0


0 = 510 - 60x

Subtract 510 from each side

-510 = 510-510-60x

-510=-60x

Divide by -60

-510/-60 = -60x/-60

8.5 = x

The maximum value of x is 8.5 hours

So x must be between 0 and 8.5 inclusive.

the two shorter sides of a triangle are the same length. the length of the longer side is 5 m longer than each of the shorter si
STatiana [176]
Let the length of the shorter sides be x, then
Perimeter = x + x + x + 5
29 = 3x + 5
3x = 29 - 5 = 24
x = 24/3 = 8

Therefore, the length of longest side is 8 + 5 = 13 m.
