Answer:

No because the x value does not change by 1 everytime the y value changes by 5

Step-by-step explanation:

Rate of Change = Slope

If the slope was 5, the the point on the graph would be on the coordinate (1,5)

However, the graph provided does NOT show 5 as being the slope because the line does not go through 0 and the x value does not change by 1 everytime y changes by 5.

If it did, however, it would look something like this picture.

A tunnel is 300 feet deep and makes an angle of 30 with the ground .

Goshia [24]

Answer:

$\boxed{C.\:\: 600\:feet}$

Step-by-step explanation:

The tunnel, the ground and the depth of the tunnel form a right angle triangle.

The length of the tunnel is the hypotenuse of the right triangle that has been formed.

Let the length of the tunnel be $m\: feet$ .

Using the sine ratio, we obtain;

$\sin(30\degree)=\frac{Opposite}{Hypotenuse}$

The length of the opposite side is $300\:feet$

We substitute the given values to obtain;

$\sin(30\degree)=\frac{300}{m}$

$\Rightarrow \frac{1}{2}=\frac{300}{m}$

We cross multiply to obtain;

$m=300\times2$

$m=600\:feet$

Therefore the correct answer is C.

Jackie wants to justify that f(x) = 2x - 6 is a linear function. If she evaluated F(x) for consecutive integer values, write a s

NISA [10]

Jackie wants to justify that f(x) = 2x - 6 is a linear function.

Lets assume some values for x and find out f(x)

We make a table with x values 1, 2, 3, 4 and find f(x)

To find f(x) we plug in x value in the given equation

x f(x)

1 2(1)-6 = -4

2 2(2)-6 = -2

3 2(3)-6 = 0

14 2(4)-6 =2

for f(x) we got -4, -2, 0 , 2

The value of f(x) is increasing by 2. There is a constant increase in f(x)

When there is a constant rate of increase then it is a linear function

constant rate of increase that is slope = 2. Hence f(x) = 2x -6 is a linear function.
