Determine whether the graphs of the given equations are parallel, perpendicular, or neither.
3x + y = 4
y=-1/3x-2​

By algebra properties, the x-value such that expression 0.5 · x - 3 = - 4.

In this problem we must determine the value of x such that the following expression is satisfied:

0.5 · x - 3 = - 4

This can be solved by means of algebra properties. First, write the entire expression:

0.5 · x - 3 = - 4

Second, clear the variable x by algebra properties:

0.5 · x = 3 - 4

0.5 · x = - 1

x = - 2

Select which is in ascending order

It should be noted that absolute values only return positives.

i.e.

∣a∣ or ∣∣a∣∣ or ∣-a∣ or ∣∣-a∣∣ = a

Having said that:

a.∣∣−514∣∣ , ∣∣−47∣∣ , ∣∣67∣∣

This gives: 514, 47, 67

This is not in ascending order

b.∣∣−23∣∣ , ∣∣−59∣∣ , ∣∣29∣∣

This gives: 23, 59, 29

This is not in ascending order

c.∣∣−38∣∣ , ∣∣34∣∣ , ∣∣−78∣∣

This gives: 38, 34, 78

This is not in ascending order

d.∣∣−110∣∣ , ∣∣−45∣∣ , ∣∣710∣∣

This gives: 110, 45, 710

This is not in ascending order

Hence, none of the list is in ascending order

Answer:

Step-by-step explanation:

The triangle is translated two units right on the x axis and none on the y-axis, as well rotated 180 degrees

Transformation involves changing the position of a shape.

The congruence transformation is (c)

Using the coordinates of point K, we have:

[tex]\mathbf{K = (-4,-4)}[/tex]

First, triangle KNO is translated 2 units right, and 2 units up.

So, we have:

[tex]\mathbf{K = (-4-2,-4+2)}[/tex]

[tex]\mathbf{K = (-6,-2)}[/tex]

Next, the triangle is rotated 180 degrees across the origin.

The rule of this transformation is:

[tex]\mathbf{(x,y) \to (-x,-y) }[/tex]

So, we have:

[tex]\mathbf{K = (6,2) }[/tex]

The corresponding point of K on triangle AWN is A.

So, we have:

[tex]\mathbf{A = (6,2) }[/tex]

Hence, the correct option is (c)

Answer:

The light intensity is 528 foot-candles at 5 feet

Step-by-step explanation:

If x and y are in inverse variation, then x y = k, where k is the constant of variation

In the given question

∵ The intensity I, of light received at a source, varies inversely as the

   square of the distance d, from the source

→ That means I × d² = k, where k is the constant of variation

∴ I × d² = k

∵ I = 33 foot-candle at d = 20 feet

→ Substitute them in the rule above to find k

∴ 33 × (20)² = k

∴ 33 × 400 = k

∴ 13200 = k

→ Substitute the value of k in the equation

∴ I × d² = 13200 ⇒ equation of variation

∵ d = 5

→ Substitute it in the equation to find I

∵ I × (5)² = 13200

∴ I × 25 = 13200

→ Divide both sides by 15

∴ I = 528

∴ The light intensity is 528 at 5 feet

y <  [tex]\frac{1}{3}[/tex] x - 2

Step-by-step explanation:

Slope of the line m = [tex]\frac{-4+1}{-6-3}[/tex] = [tex]\frac{1}{3}[/tex]

y + 1 = [tex]\frac{1}{3}[/tex] (x - 3)

y = [tex]\frac{1}{3}[/tex] x - 2

Points (9, 1) and (- 4, 7) are not solutions, then

1 < [tex]\frac{1}{3}[/tex] (9) - 2

7 < [tex]\frac{1}{3}[/tex] (- 4) - 2

Thus, the inequality is y <  [tex]\frac{1}{3}[/tex] x - 2

Step-by-step explanation:

For all Plato users

The amount of concrete needed after doubling the diameter of the circle will be multiplied by 4 by the initial amount. Hence, the correct option is (B).

Direct proportions are the proportions where a variable changes with another variable by direct mean so the coefficient of constant will be direct.

For example y ∝ x² here y varies with respect to x square.

y = Kx² where k will be the coefficient of constant.

Given that amount is Amount ∝ d²

Amount = k d²

By doubling the diameter

Amount = k (2d)²

Amount = 4 kd²

Amount = 4 × initial amount hence, the amount will be multiplied by 4.

Answer:  g(x) = (x-2)^2 + 1. Choice C

===========================================================

Explanation:

The graphs have the same shape, which means they have the same 'a' value.

In this case, a = 1.

The vertex of the red graph is (0,0).

The vertex of the blue parabola is (2, 1)

The red curve has been shifted 2 units to the right and 1 unit up.

Since the vertex of the blue graph is (2,1), this means h = 2 and k = 1.

Plug a = 1, h = 2 and k = 1 to get...

y = a(x-h)^2 + k

y = 1(x-2)^2 + 1

g(x) = (x-2)^2 + 1

Answer:

C.

Step-by-step explanation:

Since the blue graph shifted up by 1 unit, it would be +1 at the end of the quadratic function. Then, because the graph also shifted to the right 2 units, the blue graph subtracts from f(x)=x^2 (it does the opposite).

Answer:

  800(9 +√2) cm² ≈ 8331.4 cm²

Step-by-step explanation:

The surface area of the pyramid is the sum of the areas of the base and triangular faces.

The base area is given by ...

  A = 2(1 +√2)s² . . . . . where s is the length of one side

  A = 2(1 +√2)(20 cm)² = 800(1 +√2) cm²

The lateral area is given by ...

  A = (1/2)Ph . . . . . where P is the perimeter of the base and h is the slant height

  A = (1/2)(8)(20 cm)(80 cm) = 6400 cm²

Then the total surface area of the pyramid is ...

  SA = (800(1 +√2) +6400) cm² = 800(9 +√2) cm² ≈ 8331.4 cm²

Step-by-step explanation:

Subtract 2z2z from both sides of the equation.

x−2y+z=1x-2y+z=1

y=5−2zy=5-2z

x+y+3z=8x+y+3z=8

Replace all occurrences of yy with 5−2z5-2z in each equation.

x−2(5−2z)+z=1x-2(5-2z)+z=1

y=5−2zy=5-2z

x+5−2z+3z=8x+5-2z+3z=8

Simplify each equation.

x−10+5z=1x-10+5z=1

y=5−2zy=5-2z

x+5+z=8x+5+z=8

Move all terms not containing xx to the right side of the equation.

x=11−5zx=11-5z

y=5−2zy=5-2z

x+5+z=8x+5+z=8

Replace all occurrences of xx in x+5+z=8x+5+z=8 with 11−5z11-5z.

x=11−5zx=11-5z

y=5−2zy=5-2z

(11−5z)+5+z=8(11-5z)+5+z=8

Simplify (11−5z)+5+z(11-5z)+5+z.

Answer:

The answer would be 45 minutes.

Step-by-step explanation:

Just skipped to the answer on Edementum.

A fraction is a way to describe a part of a whole. The time it takes Edward to cut the lawn alone is 45 minutes.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Let the time taken by Maya to lawn the garden be x.

The rate at which Maya lawn = 1/x

Maya has a newer lawnmower, so Edward takes 15 minutes longer to cut a lawn than Maya. Therefore,

The rate at which Edward lawn = 1/(x+15)

Working together they can both cut a lawn in 18 minutes.

The rate at which they both work = 1/18

Now, the rate of working can be compared as,

1/x + 1/(x+15) = 1/18

(x+ x + 5)/x(x+15) = 1/18

(2x + 15)18 = x(x+15)

36x + 270=x² + 15x

x²-21x-270=0

x = 30, -9

Since time can not be negative. Therefore, the time it takes Edward to cut the lawn alone is,

x + 15

= 30 + 15

= 45 minutes

Hence, the time it takes Edward to cut the lawn alone is 45 minutes.
