Mathematics

Start with

2(x-3)+9=3(x+1)+x

Expand both parentheses by multiplying both terms by the number outside:

2x-6+9 = 3x+3+x

Sum like terms:

2x+3 = 4x+3

Simplify the "+3" on both sides:

2x = 4x

Subtract 2x from both sides:

2x=0

Divide both sides by 2:

x=0

If the exponential parent function,
laila [671]

Answer: f(x) =3^{-x}-4

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

If f(x)+k, the function is translated up "k" units.

If f(x)-k, the function is translated down "k" units.

If -f(x), the function is reflected across the x-axis.

If f(-x), the function is reflected across the y-axis.

Therefore, knowing those transformations and given the exponential parent function:

f(x) = 3^x

If it is reflected across the y-axis and the it is  translated down 4 units, we can determine that the resulting function is:

f(x) =3^{-x}-4

If you flip a coin and roll a 6-sided die, what is the probability that you will flip a tails and roll at least a 2?
Finger [1]

Step-by-step explanation:

Flipping a tails and rolling at least a tail are 2 independent events: they don't affect each other. So, to get the probability of both happening, we just need to multiply the probability of one by the probability of the other. he probability of rolling at least a 2 is 5/6.

Imagine drawing a figure with the following conditions: A quadrilateral with at least two right angles. Is the figure described
Mrac [35]

Answer:

The figure is NOT unique.

 Imagine the following quadrilaterals:

 Rectangle

 Square

 We know that:

 Both quadrilaterals have at least two right angles.

 However, they are not unique because they depend on the lengths of their sides.

Step-by-step explanation:

To construct a quadrilateral uniquely, five measurements are required.  A quadrilateral can be constructed uniquely if the lengths of its four sides and a diagonal are given or  if the lengths of its three sides and two diagonals are given.

Just given two angles we cannot construct a unique quadrilateral.  There may be an infinite number of quadrilaterals having atleast two right angles

Examples:

All squares with varying sides

All trapezoids with two right angles

All rectangles with different dimensions

and so on.

Answer is

No.
