"fifty seven miles over three gallons" is the right answer

Step-by-step explanation:

Given unit rate is:

19 miles per gallon

We have to see that which of the given options equals to the given unit rate

So,

three gallons over fifty seven miles

$\frac{3\ gallons}{57\ miles} = \frac{1}{19}\ gallons\ per\ mile$

fifty seven miles over three gallons

$\frac{57\ miles}{3\ gallons} = 19\ miles\ per\ gallon$

Hence,

"fifty seven miles over three gallons" is the right answer

Which of the following is true of the location of an angle, Theta, whose tangent value is - sqrt3/3?

prohojiy [21]

Answer:

Step-by-step explanation:

Keep in mind that the tangent function is negative in Quadrants II and IV.

Of the three possible answers, the 2nd is invalid because the tangent is positive in Q III.

If the reference angle were in Quadrant II and had the value 30° (second possible answer), then the opposite side would be +1, the adjacent side -√3 and the hypotenuse 2. Based on this, the tangent of theta would be opp / adj, or +1 / (-√3) or -√3/3. This is correct.

Need help in math and explain to me step by step

Rus_ich [418]

Answer:

$\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]$

Step-by-step explanation:

Given

$y = 4x - 1$

Required

Create a function table for inputs -2, 0, 2 and 4

When x = -2

$y = 4*-2 - 1 = -9$

When x = 0

$y = 4*0 - 1 = -1$

When x = 2

$y = 4*2 - 1 = 7$

When x = 4

$y = 4*4 - 1 = 15$

So, the table is:

$\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]$

Find the equation of line passing through points A (1, 3) and B (3, 7).

Sidana [21]

Solution:

To find the equation of line passing through points A (1, 3) and B (3, 7).

we know that, to derive the equation of a line we first need to calculate the slope of the line. Slope m of a line at points $(x_{1} ,y_{1})$ and $(x_{2}, y_{2})$ is given by - $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .
