Answer:

4

Step-by-step explanation:

p(x) = (x - 1) (x + 1) \\ plug \: x = 2 \: 1 \: 0 \: we \: find:   \\ \\ p(2) = (2 - 1) (2 + 1) = (1)(3) = 3 \\  p(1) = (1 - 1) (1 + 1) = (0)(2) = 0 \\   p(0) = (0 - 1) (0 + 1) = ( - 1)(1) =  - 1 \\  \\ p(2) + p(1) - p(0) \\  = 3 + 0 - ( - 1) \\  = 3 + 1 \\  = 4

During summer, when the snow melts, the water level of the Yukon River increases. If the water level of the river increased by 7
kondaur [170]

Answer:

13 centimeters per day.

Step-by-step explanation:

We have been given that during summer, the water level of the river increased by 78 centimeters in 6 days. We are asked to find the water level increase rate in centimeters per day.

To find the water level increase rate per day, we will divide total increase by total days as:

\text{Water level increase rate per day}=\frac{78\text{ cm}}{6\text{ days}}

\text{Water level increase rate per day}=\frac{13\text{ cm}}{\text{ day}}

Therefore, the water level increase rate is 13 centimeters per day.

Just Need A Few Questions Answered To Finish My Quiz, Any Help Would Be Much Appreciated.

Given the triangle

PQR

with points

P(8,0)

Q(6,2)

R(-2,-4)

And the triangle

P'Q'R'

with points

P'(4,0)

Q'(3,1)

R'(-1,-2)

Part A. Scale factor

Using the vertex

P( 8, 0)

P'(4,0)

the dilatation factor is given by

\frac{4}{8}=\frac{1}{2}

The triangle has a dilatation factor of 1/2

Part B:

P''Q''R'' after using P'Q'R' reflected about the y axis

to make a reflection over the y axis

coordinates (x,y) turn into coordinates (-x,y)

as follows

P^{\prime}(4,0)\rightarrow P^{\prime\prime}(-4,0)Q^{\prime}(3,1)\rightarrow Q^{\prime\prime}(-3,1)R^{\prime}(-1,-2)\rightarrow R^{\prime\prime}(1,-2)

Then triangle P''Q''R'' has coordinates

P''(-4,0)

Q''(-3,1)

R''(1,-2)

Part C:

PQR is congruent to P''Q''R''?

Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal.

Then the triangles are not congruent

Solve it plz 29x < 38x + 18
storchak [24]

Answer:

x= -2

Step-by-step explanation:

The first thing I did was isolate the x's on one side.  I subtracted 38x from both sides.  This gives me:

-9x=18.  

Now i divide both sides by -9.  Giving me x=-2
