How do we translate a statement into an inequality

Mathematics

You look for certain key words. The expression "at least" means "greater than or equal to." The expression " is no more than" means "less than or equal to." A sum means an addition. A difference is a subtraction. There are many other words that you need to look out for and translate into math symbols.

Janet invested $10,000, part at 2% and part at 12%. if the total interest at the end of the year is $600, how much did she inves
Ivan

Janet invested $6000 at 2 %.

Let <em>x</em> = amount invested at 2 %. Then 10 000 - <em>x</em> = amount invested at 12 %

interest at 2 % + interest at 12 % = 600

0.02<em>x</em> + 0.12(10 000 –<em> x</em>) = 600

0.02<em>x</em> + 1200 – 0.12<em>x</em> = 600

0.10<em>x</em> = 600

x = 600/0.10 = 6000

Question 14(Multiple Choice Worth 5 points)
ddd [48]

Answer:

Find all polar coordinates of point P where P = (5 , -pi+%2F6 ).

There are two sets of possibilities.

(1) Same (positive) magnitude and an angle that is the same as the given angle, or differs from the given angle by an even multiple of pi:

P = (5, -pi%2F6%2B2n%2Api )

(2) Opposite (negative) magnitude and an angle that differs from the given angle by an odd multiple of pi:

(-5, -pi%2F6%2B%282n%2B1%29pi)

answer is: (5,-pi%2F6+%2B+2n%2Api) or (-5, -pi%2F6%2B%282n%2B1%29pi)

the first term of an arthimetic sequence is 42 the rule an= an-1 +8 can 1 can be used explain how to write explict rules
Svet_ta [14]

Answer:

34 + 8n

Step-by-step explanation:

a₁ = 42

a_{n} = a_{n-1} + 8

a₂ = a₁ + 8    = 42 + 8   = 50

a₃ = a₂ + 8   = 50 + 8 = 58

a₄ = a₃ + 8 =   58 + 8  = 66

Arithmetic sequence: 42, 50 , 58 , 66, ......

a₁ = 42 ; d = 8

a_{n} = a₁ + d(n-1)

    = 42 + 8(n - 1)

    = 42 + 8n - 8

   = 34 + 8n
