Answer:

x = 4

Step-by-step explanation:

The line is a vertical line. The equation of a vertical line is represented as x = k.

Where, k is the point at where the line intercepts the x-axis.

In the graph given, the line intercepts the x-axis at 4. k = 4.

Therefore the equation of the vertical line would be:

x = 4

What number should be added to 7/12 to get 4/15?

DENIUS [597]

Answer:

Step-by-step explanation:

Let the number = x.

We are trying to find out what number (x) we would need to add to 7/12 to get 4/15

$\frac{7}{12} + x = \frac{4}{15}$

Subtract 7/12 from both sides.

$x = \frac{4}{15} - \frac{7}{12}$

We need to make the denominators of the fractions the same.

$\frac{4}{15} = \frac{16}{60}$

$\frac{7}{12} = \frac{35}{60}$

So,

$x = \frac{16}{60} - \frac{35}{60} = - \frac{19}{60}$

Perform the required operations on the following functions Given: f(x)= 3-x; g(x)= -2x Find g[f(x)]

N76 [4]

ANSWER

$g(f(x)) = 2x - 6.$

EXPLANATION

The given functions are;

$f(x) = 3 - x$
and

$g(x) = - 2x$

We now find

$g(f(x)) = g(3 - x)$

We plug in f(x) into g(x) to get,

$g(f(x)) = - 2(3 - x)$

We expand parenthesis to get,

$g(f(x)) = - 6 + 2x$

Or

$g(f(x)) = 2x - 6$

The following scatter plot shows the billions of dollars spent by travelers in the United States since 1993.

Dovator [93]

I think the correct answer from the choices listed above is option C. The line of best fit for the figure given above would be <span>y=20x+320 so that travelers will spend about $620 billion in the year 2008.

From the plot, y-intercept is equal to 320 and the slope (400-350) / (4-1.5) = 20.</span>
