Can someone please help me? I can't find the h(x) for 0. I also need help with the last question. Please I need it very soon.

Answer:

x=20

Step-by-step explanation:

5x+4x=180

9x=180

/9 on both sides

x=20

The value of 4x and 5x is 80° and 100° respectively .

The same-side interior angle theorem states that when two lines that are parallel are intersected by a transversal line, the same-side interior angles that are formed are supplementary, or add up to 180 degrees.

According to the question

4x , 5x are angles given

As,

They are angles between  parallel line and same side of transversal line  

according to same-side interior angle theorem that are formed are supplementary .

i.e  there sum = 180°

4x + 5x= 180°

9x = 180°

x = 180°/9

x = 20°

So,

4x = 20 * 4 = 80°

5x = 20 * 5 = 100°

Hence, The value of 4x and 5x is 80° and 100° respectively .

Answer:

y=2x-5

Step-by-step explanation:

The two triangles could be similar by the AA similarity property. So, option C is correct.

AA is angle-angle similarity property.

In the given figure, both of these triangles show two given angles which are 42 degrees.

The other two sides are different and not proportional to each other.

So, The two triangles could be similar by the AA similarity property.

Complete question is;

In a survey of 565 U.S. businesses, 430 of these companies indicated that they monitor employees' web site visits. For purposes of this exercise, assume that it is reasonable to regard this sample as representative of businesses in the United States.

Is there sufficient evidence to conclude that more than 75% of U.S. businesses monitor employees' web site visits? Test the appropriate hypotheses using a significance level of 0.01. (Round your test statistic to two decimal places and your P-value to four decimal places.)

Answer:

There's not sufficient evidence to suggest that more than 75%  of U.S. businesses monitor employees website visits.

Step-by-step explanation:

Population proportion; p^ = 430/565 = 0.761

Sample proportion; p = 75% = 0.75

Significance level; α = 0.01

Sample size; n = 560

Let's define the hypotheses;

Null hypothesis; H0: p = 0.75

Alternative hypothesis: p > 0.75

Formula for the test statistic is;

z = (p^ - p)/√[p^(1 - p^)/n]

z = (0.75 - 0.761)/√(0.75(1 - 0.75)/560)

z = -0.011/√0.00033482143

z = -0.011/0.0183

z = -0.60

From online p-value from z-score calculator attached, using; z = -0.60, significance level = 0.01, one tailed hypothesis, we have;

P-value ≈ 0.2743

The p-value is greater than the significance level and so we will fail to reject the null hypothesis and conclude that there's not sufficient evidence to suggest that more than 75%  of U.S. businesses monitor employees website visits.

ΔABD ≅ ΔCBD by SAS Congruence Postulate (Option C)

Step-by-step explanation:

In ΔABD & ΔCBD ,

1) AD = CD = 15 units

2) ∠ADB = ∠CDB (∵ BD is angle bisector)

3) BD = BD (common side)

∴ ΔABD ≅ ΔCBD by SAS congruence postulate.

Answer:

Triangles ABD and CBD are congruent by SAS.

Step-by-step explanation:

Sides AD and CD are congruent since they both measure 15.

Angles ADB and CDB are congruent because of the angle bisector.

Side DB is congruent to itself.

By SAS, triangles ABD and CBD are congruent.

Answer: Triangles ABD and CBD are congruent by SAS.

Answer:

w=1.5 or w=13.5

Step-by-step explanation:

this is one answer:

multiply w on both sides to leave u with

4.5=3w

divide both sides by 3

[tex]\frac{4.5}{3}=\frac{3w}{3}[/tex]

1.5=w

_____________________

this is the second one if the first one is wrong:

multiply 4.5 on both sides so that the 4.5/w would leave u with just only w alone.

then 3*4.5=13.5

w=13.5

Step-by-step explanation:

There are several ways to solve this, but the only one I remember how to do is with the pythagorean theorem. The distance between A and B is the same as a hypotenuse of a triangle with a height the absolute value of y1-y2 and a base of the absolute value of x1-x2.

For example, in the first question, the coordinates are (1,2) and (9,8), so we have a triangle with base 8(9 - 1) and 6(8 - 2). Now we just need to plug that into the pythagorean theorem like so:

[tex] {a}^{2} + {b}^{2} = {c }^{2} [/tex]

or plugging our numbers in,

[tex]8^{2} + {6}^{2} = 100[/tex]

The answer is the radical of the answer, in this case 10.

So if this makes sense, go ahead and try to work the next three out on your own, and if you still need help let me know <:

Answer:

Step-by-step explanation:

They are both the same ab and bc but im not entirely  sure

Because AB, AC, and BC describe the same line, we conclude that the last option is the false one.

On the graph, we can see a line that contains points A, B, and C.

Now we want to see which statement is false.

Now, because A, B, and C are on the same line, is trivial that:

AB, AC, and BC (these 3 lines) have the same slope, because these are 3 different names for the exact same line.

Then we can conclude that the incorrect statement is the last one.

Answer:

  P = 3x +32

Step-by-step explanation:

If we assume the short vertical edge at top center is 10 yards, as it was in two previous problems with this geometry, then we can find the area of the present parking lot as ...

  (x-2)(3x) + x(3x -10) +2x(40) = 6x^2 +64x

where the left vertical rectangle is 3x high and x-2 wide; the center area between vertical rectangles is (2x-2)-(x-2) = x wide and (3x-10) high; and the right vertical rectangle is (x-2 +3x)-(2x-2) = 2x wide and 40 high.

As we said, the right vertical rectangle is 2x wide, so the area that has P as one of its dimensions is ...

  A = LW = P(2x)

We want this to be the same as the existing area, so ...

  2Px = 6x^2 +64x

  P = 3x +32 . . . . . divide by 2x
