Order of operations: the rules of which calculation comes first in an expression.

They are: PEMDAS

<span><span>Do everything inside parentheses first: ()
</span><span>then do exponents: x2
</span><span>then do multiplies and divides from left to right
</span><span>lastly do the adds and subtracts from left to right</span></span>

Order of operations is a certain rule found in mathematics. Also known as BODMAS, the order goes Brackets any numbers or operation in brackets,
Of like any power, D for divison, M miultiplication A addition and S subtraction. 
You must follow the order, but if there are 2 DM or 2 AS in a row, you can do it from left to right.
Hope it helps :)

stira [4]

Answer:

For this transition of equations, the graph of g(x) will be translated left 2 units with respect to the graph of f(x), so your answer choice will be A.

Step-by-step explanation:

In this equation, g(x) is changed by adding 2 and closing part of the equation in parenthases, this results in the translation 2 units left, which can be proven by a graph and my answer.

7. Find an equation of the line containing (- 4,5) and perpendicular to the line 5x - 3y = 4.
bagirrra123 [75]

The equation of the line containing (- 4,5) and perpendicular to the line 5x - 3y = 4 is y = -3 / 5 x + 13 / 5

<h3>How to find the equation of a line?</h3>

The equation of a line can be represented as follows:

y = mx + b

where

  • m = slope
  • b = y-intercept

Therefore, the equation passes through (-4, 5) and perpendicular to 5x - 3y = 4

Hence,

perpendicular lines follows the rule below:

m₁m₂ = -1

Hence,

5x - 3y = 4

5x - 4 = 3y

y = 5/ 3 x - 4 / 3

m₁ = 5 / 3

5/3 m₂ = -1

m₂ = - 3 / 5

Hence,

using (-4, 5)

5 = - 3 / 5 (-4) + b

5 = 12 / 5 + b

b = 5 - 12 / 5 = 25 - 12 /5 = 13 / 5

Therefore,

y = -3 / 5 x + 13 / 5
