Answer:

addition

Step-by-step explanation:

18 ( d - 9 ) = 198

divide both side by 18

d - 9 = 198

3 18

d - 9 = 11

multiply both sides by 3

d - 27 = 33

add 27 to both sides

d = 33 + 27

lastly, add them together

d = 60

therefore, the last step is addition

Robert works in a toll booth. About 18 to 23 cars pass through Robert's booth every 23 minutes. Which is a reasonable estimate f

BARSIC [14]

A reasonable number between 18 and 23 is 20. 69 minutes is 3 times 23 minutes, so we multiply the 20 by 3, getting an estimate of 60 cars.

What is the frequency of the sinusoidal graph ?

disa [49]

Answer:

The frequency of the given sinusoidal graph is 4.

Step-by-step explanation:

The frequency of a sinusoidal graph is the number of cycles it completes in the interval 0 to 2π radians.

From the given sinusoidal graph it is noticed that the the graph complete its one cycle in the interval 0 to $\frac{\pi}{2}$ .

If the complete its one cycle in $\frac{\pi}{2}$ , then the number of cycles completed by the graph in the inteval 0 to 2π is

$\frac{\pi}{2}\times frequency=2\pi$

$frequency=2\pi \times \frac{2}{\pi}$

$frequency=4$

Therefore the frequency of the given sinusoidal graph is 4.

A line passes through the points (0, 2) and (1, 6). What is its equation in slope-intercept form?

olchik [2.2K]

Answer:

y=4x+2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(6-2)/(1-0)

m=4/1

m=4

y-y1=m(x-x1)

y-2=4(x-0)

y-2=4x

y=4x+2
