Answer: y = 2/5 --> y = 0.4

Step-by-step explanation:

The equation 5y = 2 represents a horizontal line at y = 2/5.

This means that the y-coordinate holds the value of 2/5 = 0.4 for any x-coordinate.

Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use:
Zina [3914]

Examining Talia's steps to derive the line equation, we identify the erroneous step as detailed below:
Step 1:
Select a point on the line, such as (2,5)
Step 2:
<span>Select another point on the line, such as (1, 3)
Step 3:
</span><span>Measure units to find the slope. The line moves 1 unit to the right and 2 units upward, resulting in a slope of
(5-3)/(2-1) = 2/1 = 2
Step 4:
</span><span>Apply these values in the point-slope form
y - y1 = m(x - x1)
y - 3 = 2(x - 1)
y = 2x + 1
Hence, the conclusion is:
</span><span>Step 4 is erroneous due to incorrect application of (1, 3) in the point-slope format.</span>

The missing value associated with x=-1 is y=6

Explanation:

The provided equation for the table is y=2-4x

This table consists of 2 columns and 5 rows.

To find the value for y when x=-1

The value of y can be ascertained by substituting x=-1 into the equation y=2-4x

PIT_PIT [3919]

Complete Question

The entire question can be found in the first uploaded image

Answer:

The expense for acquiring 100 shares of ODX group Inc and 300 shares of peer Comms Lts is

         C  =  \$ 775

Step-by-step explanation:

   From the chat, the expense for 100 shares of ODX is \$175

    The price of 100 shares of peer Comms Lts is \$ 200

Thus, the cost for 300 shares of peer Comms Lts amounts to k  =  3 * 200 =  \$ 600

Overall, the total cost for 100 shares of ODX group Inc and 300 shares of peer Comms Lts can be calculated as

           C  =  175 + 600

           C  =  \$ 775

the number of years that brad has been on the soccer team is 2 less than 5 times the number of years that scott has in total the
PIT_PIT [3919]
Let the number of years Brad has been on the soccer team be represented by x, and let y represent the number of years Scott has been on the same team.

From the information given, we formulate the equations:
5y - 2 = x -----(1)

x + y = 10 -----(2)

Now, substituting equation (1) into equation (2):
5y - 2 + y = 10
6y - 2 = 10
6y = 12
y = 2
Next, substituting this value back to find x:
x = 5×2 - 2
x = 8

So, Brad has spent a total of 8 years in the team.
