Answer:

C is correct

Step-by-step explanation:

Given: System of linear inequality

y

y\geq 2x+3

First we will draw the graph of system of equation and then see the correct option.

Equation 1: y

We will make the table.

 x :  -2    0     2

 y :   1     0    -1

Test Point: (0,4)

0<-2 ( False )

Shaded area away from (0,4)

Equation 2:y\geq 2x+3

We will make the table.

 x :  -2    0     2

 y :  -1     3    7

Test Point: (0,4)

4≥3 ( True )

Shaded area towards (0,4)

Please see attachment for graph.

Hence, C is common shaded area (region)

I need the measure of angle 3
blsea [12.9K]

Answer:

79°

Step-by-step explanation:

Since, 101° and angle 3 are interior angles falling on the same side of transversal.

Therefore,

101 \degree + m \angle \: 3 = 180 \degree \\  \\  m \angle \: 3 = 180 \degree  -101 \degree  \\  \\ m \angle \: 3 = 79 \degree

How can you write (x-3)(x+4)-18 as a product of two binomials? Please show work please help
svetlana [45]

Answer:

(b)  (x-3)(x+4)-18 = (x+6)(x-5)

Step-by-step explanation:

Here , the given expression is P(x) = (x-3)(x+4)-18

Simplifying the given expression ,we get:

(x-3)(x+4)-18 = x(x+4) -3(x+4) -18\\=x^2 + 4x-3x-12-18\\=x^2+x-30\\=x^2 +6x-5x-30\\=x(x+6)-5(x+6)\\=(x+6)(x-5)\\\implies  (x-3)(x+4)-18 = (x+6)(x-5)

So,the given polynomial P(x) can also be written as (x+6)(x-5)

Hence, P(x) = (x-3)(x+4)-18 = (x+6)(x-5)

Solve for x. x2 = 100 A. -200, 200 B. -100, 100 C. -50, 50 D. -10, 10
ICE Princess25 [194]

Answer:

D. -10, 10

Step-by-step explanation:

Instead of inserting values into x to solve, let's isolate x.

In order to do this, we must take the square root of both sides.

\sqrt{x^{2} } =\sqrt{100}

x=\sqrt{100}

To find the square root of 100, we must figure out what = 100 when multiplied by itself. Reminder, it can be both a positive or a negative square root, as positive times positive is a positive, and negative times negative is a positive.

The square root of 100 is -10 or 10, as 10 x 10 or -10 x -10 = 100.

<u><em>Hope this helps! :)</em></u>
