See in the attached file

<h2>Explanation:</h2>

In this case we have the following system of inequalities:

(1) \ y\geq 2x + 1 \\ \\ (2) \ y\leq 2x - 2​

First of all, let's plot the equations:

y=2x + 1 \\ \\ \\ \bullet \ If \ x=0 \ then: \\ \\ y=2(0)+1 \therefore y=1 \\ \\ Point \ 1: (0,1) \\ \\ \\ \bullet \  If \ y=0 \ then: \\ \\ 0=2x+1 \therefore x=-1/2 \\ \\ Point \ 2: (-1/2,0) \\ \\ \\ The \ line \ passes \ through \ these \ two \ points

y=2x-2 \\ \\ \\ \bullet \ If \ x=0 \ then: \\ \\ y=2(0)-2 \therefore y=-2 \\ \\ Point \ 1: (0,-2) \\ \\ \\ \bullet \  If \ y=0 \ then: \\ \\ 0=2x-2 \therefore x=1 \\ \\ Point \ 2: (1,0) \\ \\ \\ The \ line \ passes \ through \ these \ two \ points

From:

(1) \ y\geq 2x + 1

The symbol ≥ tells us that the shaded region (the red one) lies above the line and includes all the points on the line.

From:

(2) \ y\leq 2x - 2​

The symbol ≤ tells us that the shaded region (the green one) lies under the line and includes all the points on the line.

Therefore, the graph that stands for this problem is shown below. As you can see, there is no intersection between the two shaded regions, so there is no any solution there.

One angle of an isosceles triangle measures 76º. Which other angles could be in that
GREYUIT [131]

Answer:

52 or 28

Step-by-step explanation:

An isosceles has 2 congruent angles.

There are 2 possibilities:

A) There are two 76-deg angles and one angle of a different measure.

76 + 76 + x = 180

x = 28

B) There are two congruent angles, and 76 is the non-congruent angle.

x + x + 76 = 180

2x = 104

x = 52

Answer: 52 or 28

 A movie projector positioned 34 feet from a wall creates an image that is 8 feet wide on the wall. if a screen is placed 5 fee
inessss [21]

Answer: 1.48ft

Step-by-step explanation:

The angle, θ, at which the projector "spreads" the image is constant.

We know that:

"A movie projector positioned 34 feet from a wall creates an image that is 8 feet wide on the wall"

We can think this problem as the image in the end, two triangle rectangles with cathetus equal to 34 ft, and 8/2 ft = 4ft

Then this angle θ can be calculated because we know the two cathetus of this triangle:

Tan(θ) = (opposite cathetus)/(adjacent cathetus)

Tan(θ) = 4ft/34ft

θ = Cotan(4/34) = 8.46°

Now, if you move the place the projector 5ft from the wall, now the adjacent cathetus is 5ft instead of 34.

Then we have:

Tan(8.46°) = x/5ft

Tan(8.46°)*5ft = x = 0.74ft

But remember that the actual width of the image will be two times that, so the width is:

W = 2*0.74ft = 1.48ft

Consider the polynomial p(x)=8x3+12x2+2x+3.
Ivahew [28]

A: (4x^2+1)(2x+3)

B: grouping

Step-by-step explanation:

We are given the polynomial: p(x)=8x^3+12x^2+2x+3

Part A: What is the correct factorization of p(x)=8x^3+12x^2+2x+3 over the integers?

We need to factorize the term p(x)=8x^3+12x^2+2x+3

Factorizing by grouping:

p(x)=8x^3+12x^2+2x+3

p(x)=(8x^3+12x^2)+(2x+3)

p(x)=4x^2(2x+3)+1(2x+3)

p(x)=(4x^2+1)(2x+3)

So, factors of the term p(x)=8x^3+12x^2+2x+3 are p(x)=(4x^2+1)(2x+3)

Part B: What method is used to factor p(x)=8x3+12x2+2x+3?

The method used to factor the given polynomial is grouping.

We group the terms and then find the common terms in that specific group

So, the answers are:

A: (4x^2+1)(2x+3)

B: grouping

a bicycle costs $198.99. If the sales tax is 8%, what will be the final cost of the bicycle including tax (in dollars)?
Tasya [4]
If the sales tax is 8%, then you multiply the previous cost by (1 + 0.08).

198.99 x (1.08) = 214.91.

Final Cost: $214.91.
