Solve using elimination, 2x+5y=2 3x-5y=53

Answers

Answer 1

Answer: 2x + 5y =2
(+) 3x - 5y =53
-------------------------
5x + 0 = 55

Then finish it.

5x = 55
x = 11

Substitute x = 11,

2(11) + 5y = 2
22 - 2 + 5y = 0
20 + 5y = 0
5y = -20
y= -4

Answer 2

Answer: 2x+5y=2
3x-5y=53
---------------
+
2x+3x=2+53
5x=55 / : 5
x=11

x=11
3x-5y=53

x=11
3*11-5y=53

x=11
33-5y=53

x=11
-5y=53-33

x=11
-5y=20 / : (-5)

x=11
y=-4

Answers

If you would like to know the value of f(4), you can calculate this using the following steps:

f(n) = 1/2 * f(n-1) + 2
f(1) = 8

f(2) = 1/2 * f(2-1) + 2 = 1/2 * f(1) + 2 = 1/2 * 8 + 2 = 4 + 2 = 6
f(3) = 1/2 * f(3-1) + 2 = 1/2 * f(2) + 2 = 1/2 * 6 + 2 = 3 + 2 = 5
f(4) = 1/2 * f(4-1) + 2 = 1/2 * f(3) + 2 = 1/2 * 5 + 2 = 5/2 + 2 = 5/2 + 4/2 = 9/2 = 4 1/2

The correct result would be 4 1/2.

What is the shape color of the obtuse angle

Answers

The shape and color of an obtuse angle can vary depending on the context in which it is used.

An obtuse angle is any angle greater than 90 degrees but less than 180 degrees. It can be formed by two intersecting lines or sides of a polygon where the angle between them is more than 90 degrees but less than 180 degrees.

The shape of an obtuse angle is typically represented by an arc, where the two intersecting lines or sides meet to form the angle. The color of the obtuse angle can be any color, as it does not have a specific color associated with it. It may be represented using different colors in diagrams or drawings to distinguish it from other angles or elements.

If you have a specific context or application in mind, please provide more details, and I'll be happy to assist you further.
