Write an equation in standard form that is parallel to the line y = 2x - 1 that passes through the point (1, 2). 2x - y = 0 O x

- 2y = 1 0 + -2x + y = 0 O x + y =3​

Answer:

2x - y = 0

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x - 1 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

y = 2x + c ← is the partial equation

To find c substitute (1, 2) into the partial equation

2 = 2 + c ⇒ c = 2 - 2 = 0

y = 2x ← equation in slope- intercept form

Subtract y from both sides

0 = 2x - y , that is

2x - y = 0 ← equation in standard form

Explanation:
___________________________________
  It would be best to list this values in the data set given, from least to greatest:
________________________________________________
  { 3, 3, 3, 3, 4, 5, 5, 6, 9 } .
________________________________________________
  The mode is the number that occurs most frequently in the data set, which is: "3".
_________________________________________________________
{The number, "3", occurs FOUR (4) times.  The number, "4", occurs ONE (1) time.  The number, "5", occurs TWO (2) times.  The number, "6", occurs ONE (1) time.  The number, "9", occurs ONE (1) time.}.
___________________________________________________
The range is calculated from subtracting the LOWEST value in the data set FROM the HIGHEST value in the data set.
____________________________________________________
 The lowest values in the data set is: "3" .
 
 The highest value in the data set is: "9" .
________________________________________________
 To calculate the range:  9 <span>− 3  = 6 .  The range is:  "6".

Plz help with this math. Can't find the area of the triangular faces.
Zina [86]
First of all, you have to find the area of both triangles:
\frac{bh}{2}
\frac{4*4}{2}
Or just 16 because there are 2 of the same triangles.

Now you have to find the area of the 3 rectangles.

The two that are in the front are 4*3 (l*h) or 12*2 (because there are 2 congruent rectangles. The area of those rectangles is 24 square mm.

Now you find the area of the back rectangle:
5.7*3 = 17.1

Finally, you add all the found numbers to figure out the surface area.
17.1 + 16 + 24 = 57.1 square millimeters.

Hope this helped,
