Algebra

Algebraic is used as a word that 2 or more terms are either an expression or an equation such as 3x+2y+1 is an expression but 2y = 3x+1 is an equation because it contains an equality sign

OBTUSE /

Less 90 degrees ; ACUTE

90 degrees ; RIGHT ANGLE

Obtuse greater than 90 degrees but less than 180 degrees

180 degrees arc swept by a point on a straight line

REFLEX ; greater than 180 degrees but less than 360 degrees. ( The 'outside' of an acute or obtuse angle)/

Perimeter is NOT squared.

Squaring calculated the area inside the perimeter.

The perimeter is the addition of the lines that form the edge/perimeter.

For the general straight line eq'n ; y = mx + c

'm' is the slope

'c' is the y-intercept.

For a pair of point on a graph ( x1,y1,) & ( x2,y2)

Then

m = {y1 - y2) / ( x1 -x2)

Note the 'y' co-ords go on the top , and the 'x' co-ods go on the botton.

Note also The position of first term '1' and the second '2' term. Otherwise you will have a wrongly calculated slope/gradient.

22 divided by 7

That is an APPROXIMATE value of pi. The exact value cannot be calculated since pi is a transcendental number - a special kind of irrational number. It has an infinite decimal representation with no recurring pattern. That would be true in any base - binary, octal, or another base (other than pi itself, or a power of pi).

i will give you a very smart trick to find the ten percent of any number in just 2 seconds.

See , 10 % 0f 500 = 50.0

10 % of 3500 = 350.0

you have to put a decimal just after the unit digit's place and you are done,

So for 10 % 0f 110,000 = 11000.0

3x = x + 10

Subtract 'x' from both sides.

2x = 10

divide both sides by '2'

x = 5

9/5 means '9' divided by '5'.

When you divide '9' by '5' that answer is '1' with a remainder of '4'.

The remainder of 4' is placed over the denominating '5'.

Hence as a mixed number. it is ' 1 4/5 '.

Oh, dude, if the circumference of a circle is 8 inches, you just divide that by π (pi) to get the diameter. So, 8 divided by π is about 2.55 inches. There you go, now you can impress all your friends with your circle knowledge.

9x^(2) + 16 DOES NOT factor.

Remember ; two squared terms with a plus(+) between them DOES NOT factor

However, two squared terms with a minus(-) between them DOES factor .

Hence 9x^(2) + 16 = (3x)^2) + 4^(2) does NOT factor

However, 9x^(2) - 16 = (3x)^2) - 4^(2) does factor to ( (3x - 4)(3x + 4)

Note the two different signs.

2x + 7y

Berkshire shotguns were produced by the Crescent Fire Arms Company, which operated in the late 19th and early 20th centuries. The value of your 32-inch barrel side-by-side hammerless shotgun can vary greatly depending on its condition, rarity, and market demand, typically ranging from a few hundred to over a thousand dollars. For an accurate appraisal, consider consulting a firearms expert or checking recent sales of similar models.

This question cannot be answered sensibly. A square foot is a measure of area, with dimensions [L2]. A foot is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that in most cases you cannot convert between measures with different dimensions without additional information.

x - 4y = 4

Algebraically rearrange to

4y = x - 4

y = x/4 - 4/4

y = (1/4)x - 1

It is now in the form of y = mx + c

Where 'm' is the slope and 'c' is the y-intersect.

Hence the slope is ' 1/4' and y intersect is ' -1 '.

yees because if you divide everything by 8 to get y=7/8+3x/8 which is a linear function since it fits the equation y=mx+b

The word 'mathematics' comes from Classical Greek word . matema' , meaning 'to learn'.

Its correct modern English is Mathematics. often shortened to 'maths'.

No such percentage as 240% .

100% is totality.

However, as given

240/100

= 2 40.100

= 2 4/10

= 2 2/5 s a mixed fraction./number.

NB What people mean when they say something has increased by '240%' , is that it has increased by '2.4' times. However, 240% is a bigger number and sounds more impressive, but is quite incorrect.!!!!!!

The number 9000000000000000000000000000 is called nine octillion in the short scale naming system. In the long scale naming system, it is called nine quadrillion. The short scale system is commonly used in the United States and most English-speaking countries, while the long scale system is used in some European countries.

180 degrees.

6x - 13 = 47

Add '13' to both sides

Hence

6x + 13 - 13 = 47 + 13

6x = 60

Divide both sides by '6'

6x/6 = 60 /6

Cancel down

x = 10 The answer!!!!!

To solve the equation ( (5x) - (2(x - 3)) = 0 ), first distribute the -2: ( 5x - 2x + 6 = 0 ). This simplifies to ( 3x + 6 = 0 ). Next, subtract 6 from both sides to get ( 3x = -6 ), and then divide by 3 to find ( x = -2 ).

Hello! 63

174 cm is 1.74 meters.

So 1.74*1.74 = 3.0276 square meters.
