Solving Equations with the variable on each side

1 answer:

5 0

Multiply both sides by 6
(b-4)/6*6= b-4
b/2*6= 3b

Rewrite the equation
b-4= 3b

Subtract b from both sides
-4=2b

Divide both sides by 2
-2=b

Final answer: b=-2

One of the legs of a right triangle measures 1 cm and its hypotenuse measures 2 cm.

FromTheMoon [43]

Answer:

1.7 cm

Step-by-step explanation:

The formula to find the hypotenuse: $c^{2} = a^{2} +b^{2}$ . In this case, the hypotenus is given.

1) Substitute the values into the formula.

$2^{2} = 1^{2} +b^{2}$

2) Solve for $b$ .

$4 = 1 + b^{2} \\4 - 1 = b^{2}\\3 = b^{2}\\\sqrt{3} = b\\1.73205 = b$

3) Round the answer to the nearest tenth.

$1.7 = b$

What is the resulting ordered pair if the value of the independent variable is 2?

quester [9]

To find f(2), put 2 where the variable is, then do the arithmetic. It might be easier to factor out x^2:
f(x) = (-6x-4)·x^2
f(2) = (-6·2-4)·2^2
= -16·4
= -64

Then the ordered pair (x, f(x)) for x=2 is
B. (2, -64)
