Answer:

d is correct

Step-by-step explanation:

Answer:

x = -5  y = -3

Step-by-step explanation:

-3x + 2y = 9

multiply the 2nd equation by 3 to set it up for elimination

3(x - 3y)= 3(4)

3x-9y = 12

so now combine both to add

-3x + 2y = 9

3x - 9y = 12

Adding both gives you

-7y = 21

divide both by -7 and you get

y = -3

and you substitute y back into equation to get x

x - 3 (-3) = 4   gives you

x + 9 = 4

x = 4 - 9

x = -5

Answer:

? = 114

Step-by-step explanation:

Angle Formed by Two Chords  =  1/2 ( sum of Intercepted Arcs)

? = 1/2 ( 53+ 175)

? = 1/2 ( 228)

? = 114

Answer:

The correct answer would be B: x-1+x-2+x

Step-by-step explanation:

First, you would do 2+(-5), from the given equation. Then, it could be simplified to 3x-3. Then, looking at B, you would add the like terms, meaning you would add all the x´s together, and the whole numbers together, giving you 3x-3. I hope I made this easy to understand for you!

Answer:

[tex]Ratio = 1.5 : 1[/tex]

Step-by-step explanation:

Given

[tex]Ratio = 6 : 4[/tex]

Required

Express as [tex]n : 1[/tex]

[tex]Ratio = 6 : 4[/tex]

Divide ratio by 4

[tex]Ratio = 6/4 : 4/4[/tex]

[tex]Ratio = 6/4 : 1[/tex]

Express 6/4 as 1.5

[tex]Ratio = 1.5 : 1[/tex]

Hence, the equivalent of [tex]6:4[/tex] is [tex]1.5 : 1[/tex]

Answer:

(x × y) - 6 < 30

xy - 6 < 30

xy < 30 + 6

xy < 36

Step-by-step explanation:

Let us represent:

First number = x

Second number = y

The product of two numbers decreased by six is less than 30.

The algebraic expression is given as

(x × y) - 6 < 30

xy - 6 < 30

xy < 30 + 6

xy < 36

this qeustion cannot be solved! never seen it before andusally there is a number instead of a y

Estimation: 250 - 80 = 170

Answer:

544 acres

Step-by-step explanation:

There is 100% in a whole.

1% is 1/100th of the whole, or 0.01 of it. We get this because 1/100 = 1/100 = 0.01

Similarly, 0.8/100 = 0.008. We then multiply the decimal by the total to get

(0.008) ( 68000) = 544 acres

Answer: [tex]4x^2 -24x+20[/tex]

Step-by-step explanation:

If p and q are zeroes of f(x), then f(x) = k (x-p)(x-q) , where k is a constant.

Given: The function f(x)f(x) is a quadratic function and the zeros of f(x)f(x) are 1 and 5.

f(x) = k (x-1)(x-5)

y-intercept = Value of function at x=0

So, y-intercept =  k (0-1)(0-5)= 5k

Since,  y-intercept of f(x) = 20

so, 5k = 20

⇒ k= 4

Quadratic polynomial [tex]= 4(x-1)(x-5)[/tex]

[tex]=4(x^2-6x+5)\\\\= 4x^2 -24x+20[/tex]

Hence, the equation of the quadratic polynomial in standard form =[tex]4x^2 -24x+20[/tex]

Answer:

The third table

Step-by-step explanation:

It's the third table because each input does not repeat, so it means all of the inputs are unique

Repeating inputs (x) make it not a function

As their is no mention of test assuming it's not a test question

Solution

Now

As per definition of function

Thing we have to see here is x values must not repeated more than once

In table 3

Table 3 is a function

Answer:

  470.16 cm²

Step-by-step explanation:

The apothem of the base is used for two purposes: to find the area of the base, and to find the slant height of each face.

The apothem of the base for side length s is ...

  s/2 = a·tan(π/8)

  a = s/(2·tan(π/8)) ≈ 7.24 cm

The slant height of a triangular face is found using the Pythagorean theorem. The apothem of the base and the height are legs of the right triangle whose hypotenuse is the slant height. For slant height x, we have ...

  x² = 10² + a² = 100 +52.46

  x ≈ √152.46 ≈ 12.35

__

The area of the 8 triangular faces will be ...

  A = 1/2Px . . . . where P is the perimeter of the pyramid

The area of the base will be ...

  A = 1/2Pa

So, the total surface area is ...

  A = 1/2P(a + x) = (1/2)(8)(6 cm)(7.24 +12.35 cm) ≈ 470.16 cm²

The answer is 470.16 cm²

Answer:

B

Step-by-step explanation:

Answer:

[tex]Height = 30cm[/tex]

[tex]Length = 360cm[/tex]

Step-by-step explanation:

Given

Scale Measurement

[tex]Height = 2cm[/tex]

[tex]Length = 24cm[/tex]

Required

Determine the possible actual measurement

First, calculate the equivalent ratio.

[tex]Ratio = \frac{Length}{Height}[/tex]

[tex]Ratio = \frac{24cm}{2cm}[/tex]

[tex]Ratio = 12[/tex]

To do this, we pick a scale factor.

Assume the scale factor is 15.

The actual measurement will be:

[tex]Height = 2cm * 15[/tex]

[tex]Height = 30cm[/tex]

[tex]Length = 24cm * 15[/tex]

[tex]Length = 360cm[/tex]

When the scale ratio is calculated, we have:

[tex]Ratio = \frac{Length}{Height}[/tex]

[tex]Ratio = \frac{360cm}{30cm}[/tex]

[tex]Ratio = 12[/tex]

Note that both have the same equivalent ratios of 12.

So, whatever the scale ratio you use, the equivalent ratio will be the same
