What is the value of f(-1) when f(x)=2x+2? F(-1)=?
igomit [66]

Here is your function:

f(x)=2x+2

You're looking for f(-1). To get your answer, you have to replace all the x's with -1.

Here is your new equation:

f(-1) = 2(-1)+2

Multiply 2 by -1

2 \times -1 = -2

<em>Remember:</em>

MULTIPLYING

  • Positive(+) times negative(-) is equal to negative
  • Positive(+) times positive(+) is equal to positive
  • Negative(-) times negative(-) is equal to positive
  • Negative(-) times positive(+) is equal to negative

DIVIDING

  • Positive(+) divided by positive(+) is equal to positive
  • Positive(+) divided by negative(-) is equal to negative
  • Negative(-) divided by positive(+) is equal to negative
  • Negative(-) divided by negative(-0 is equal to positive

Since you're multiplying a negative number by a positive number, the answer will be negative.

Here is your new equation:

f(-1) = -2+2

Add -2 and 2:

-2+2 = 0

That means your answer is 0

        ↓

f(-1)=0

Question 3
zlopas [31]

Answer:

Area = 19.05 feet squared

Step-by-step explanation:

By applying sine rule in ΔABC,

sin(∠CAB) = \frac{\text{Opposite side }}{\text{Hypotenuse}}

sin(60°) = \frac{BC}{AC}

\frac{\sqrt{3}}{2}=\frac{BC}{4}

BC = 2√3

Area of a parallelogram is given by the formula,

Area = Base × Height

        = 5.5 × 2√3

        = 11√3

        = 19.05 ft²

Therefore, answer is Area = 19.05 ft squared.
