Answer:

x = -4/3

Step-by-step explanation:

2x+10=-4x+2

Add 4x to each side

2x+4x+10=-4x+4x+2

6x +10 = 2

Subtract 10 from each side

6x +10-10 = 2-10

6x = -8

Divide each side by 6

6x/6 = -8/6

x = -4/3

In the table below, x represents miles traveled and y represents the cost to travel by train.

Answer:

4.00

Step-by-step explanation:

Given

x: 2 , 5 , 8 , 12

y: 8.50, 15.25, 22.00. 31.00

Required

Determine the y intercept

First, we calculate the slope:

$m = \frac{y_2- y_1}{x_2 - x_1}$

Where

$(x_1,y_1) = (2,8,50)$

$(x_2,y_2) = (12,31.00)$

$m = \frac{31.00 - 8.50}{12 - 2}$

$m = \frac{22.5}{10}$

$m = 2.25$

Next, we calculate the equation:

$y - y_1 = m(x - x_1)$

Where:

$(x_1,y_1) = (2,8,50)$

$m = 2.25$

The equation becomes:

$y - 8.50 = 2.25(x - 2)$

$y - 8.50 = 2.25x -4.5$

Make y the subject

$y = 2.25x -4.5+8.50$

$y = 2.25x +4$

Take $x =0$ ; to get the y intercept

$y = 2.25*0 +4$

$y = 4$

<em>Hence, the y intercept is 4.00</em>

Which of the following is an even function?

Tpy6a [65]

Answer:

f(x) = 7

Step-by-step explanation:

In an even function of x, all powers of x are even (2, 4, 6, etc.).

In this case we have f(x) = 7, or 7x^0, which is an even function because the power (0) of x is even.
