All of the following points lie on the graph of y = 2 xexcept _____.(0, 0)
(1, 2)
(2, 4)
(3, 8)

Answers

We have a line;
y=2x
Now , we find out with points belong to this line.
(0,0); it means: x=0 and y=0
y=2*0=0; therefore this point lie on the graph of y=2x.

(1,2); it means: x=1 and y=2.
y=2*1=2; therefore this point lie on the graph of y=2x.

(2,4), it means: x=2 and y=4.
y=2*2=4; therefore this point lie on the graph of y=2x

(3,8), it means: x=3 and y=8.
y=2*3=6≠8. Therefore thispoint doesn´t lie on the graph of y=2x.

Answer: All of the following points lie on the graph of y=2x, excpet (3,8).

Solve #1 pls, I need to find the shortest side, median side, and longest side

Answers

Answer:

Shortest side = 39 cm.

Median side = 65 cm.

Longest side = 91 cm.

Step-by-step explanation:

The perimeter in total is 195 cm. The ratio of the sides are 3 : 5 : 7.

First, find how much parts there are as a whole, by combining the ratios:

3 + 5 + 7 = 15 parts.

Divide the total of parts from the total measurement:

195/15 = 13

Each part has the measurement of 13 cm.

1 part = 13 cm.

Use the following ratio to solve for each of the sides:

Shortest side: 3

3 x 13 = 39

Shortest side = 39 cm.

Median side: 5

5 x 13 = 65

Median side = 65 cm.

Longest side: 7

7 x 13 = 91

Longest side = 91 cm.

Check. Combine all side measurements together. They should equal 195:

39 + 65 + 91 = 195

(39 + 65) + 91 = 195

(104) + 91 = 195

195 = 195 (True).

What is the simplified form of the equation fraction 4 over 5 n minus fraction 3 over 5 equals fraction 1 over 5 n?n = 1
n = −3
n = fraction 3 over 4
n = fraction 1 over 4

Answers

If you would like to know the simplified form of the equation, you can calculate this using the following steps:

4/5n - 3/5 = 1/5n /*5n
4 - 3/5 * 5n = 1
4 - 3n = 1
4 - 1 = 3n
3 = 3n
n = 1

The correct result would be n = 1.

Answer:

n=1
