There is no value for the cosine of infinity or negative infinity because the cosine value does not converge or approach a set value as it gets very big or small.

Translate the sentence into an equation.
Andreas93 [3]
<h2>Translating Sentences into Equations</h2>

A key part of this is recognizing certain words to change into operations or numbers:

  • <em>quotient</em> = divide
  • <em>three more</em> = add 3
  • <em>'a/the number' </em>= use a variable (in this case, it's <em>w</em>)

<h2>Solving the Question</h2>

We're given:

  • Three more than the quotient of a number and 7 equals 6
    ⇒ 'the quotient of a number and 7' tells us we divide <em>w</em> by 7:
  • Three more than \dfrac{w}{7} equals 6
    ⇒ 'three more than' means we add 3 to the fraction:
  • \dfrac{w}{7}+3 equals 6
  • \dfrac{w}{7}+3=6

<h2>Answer</h2>

\dfrac{w}{7}+3=6

4x+3y=1 2x+5y=11 solve for x and y
Ann [662]

4x+3y=1 2x+5y=11

We'll need to use system of equations for this one.

4x+3y=1

3y=1-4x

y=-4/3x+1/3

2x+5y=1

5y=1-2x

y=-2x/5+1/5

Set these two equations equal to each other and solve for x.

-2x/5+1/5=-4/3x+1/3

x=1/7

Then plug x in to solve for y.

y=-2(1/7)/5+1/5

y=1/7
