Answer:

Equation A: x = -1 and y = 3

Equation B: x = 12 and y = 16

Step-by-step explanation:

In the complex numbers (a + bi) and (x + yi)

Equation A

∵ (x + yi) + (4 – 7i) = 3 – 4i

∴ (x + 4) + (y - 7)i = 3 - 4i

→ Compare the real parts and compare the imaginary parts

∴ x + 4 = 3 and y - 7 = -4

∵ x + 4 = 3

→ Subtract 4 from both sides

∴ x + 4 - 4 = 3 - 4

∴ x = -1

∵ y - 7 = -4

→ Add 7 to both sides

∴ y - 7 + 7 = -4 + 7

∴ y = 3

Equation B

∵ (x + yi) - (-6 + 14i) = 18 + 2i

∴ (x - -6) + (y - 14)i = 18 + 2i

→ (-)(-) = (+)

∴ (x + 6) + (y - 14)i = 18 + 2i

→ Compare the real parts and compare the imaginary parts

∴ x + 6 = 18 and y - 14 = 2

∵ x + 6 = 18

→ Subtract 6 from both sides

∴ x + 6 - 6 = 18 - 6

∴ x = 12

∵ y - 14 = 2

→ Add 14 to both sides

∴ y - 14 + 14 = 2 + 14

∴ y = 16

Given:

Superman is working at Daily Planet Newspaper P(100, 40).

Bank robbery at B(40,80).

Criminals to jail at C(130, 105).

Then fly back to the Daily Planet.

To find:

The total distance for the trip.

Solution:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using distance formula, the distance between Daily Planet Newspaper P(100, 40) and place of bank robbery at B(40,80) is

[tex]PB=\sqrt{(40-100)^2+(80-40)^2}[/tex]

[tex]PB=\sqrt{(-60)^2+(40)^2}[/tex]

[tex]PB=\sqrt{3600+1600}[/tex]

[tex]PB=\sqrt{5200}[/tex]

[tex]PB=20\sqrt{13}[/tex]

Similarly,

Distance between place of bank robbery at B(40,80) and jail at C(130,105) is

[tex]BC=\sqrt{\left(130-40\right)^2+\left(105-80\right)^2}[/tex]

[tex]BC=5\sqrt{349}[/tex]

Distance between jail at C(130,105) and Daily Planet Newspaper P(100, 40) is

[tex]CP=\sqrt{\left(100-130\right)^2+\left(40-105\right)^2}[/tex]

[tex]CP=5\sqrt{205}[/tex]

Total distance for the trip = PB+ BC +CP

[tex]Trip=2\sqrt{13}+5\sqrt{349}+5\sqrt{205}[/tex]

[tex]Trip=7.2111+93.4077+71.5891[/tex]

[tex]Trip=172.2079[/tex]

[tex]Trip\approx 172.21[/tex]

Therefore, the total distance for the trip is about 172.21 units.

Step-by-step explanation:

it is (5,-4) the first answer is backwards

Answer:

The value of m is 3 because (5^4)^3 = 244140625 and 5^12 = 244140625 also, this means they are both equal to each other. Another way of getting the correct answer is just seeing what times 4 will get you 12, as you can see

3 x 4 = 12.

So yea the answer is M = 3.

your awnser is n=1 if i wrong just message me but I'm positive that is the awnser

Answer:

The answer is 12

Step-by-step explanation:

y = -2x + 3

y = -x + 10

y = 4x + 10

y = 3/2x - 2

y = -1/2x - 1

y = x + 5

y = 25x + 5

y = .99x + 1.99

y = x - 2

y = -1.50 + 1.50

y = 42x + 27

y = -1/3x - 2

Answer:

(3x-2)(x-2)(x+1)

Step-by-step explanation:

Here, given a factor of 3x^3 -5x^2 -4x + 4, we want to fully express the polynomial as a product of its linear factor

To find the other factors, we shall divide the polynomial by the given factor

That will be;

3x^3-5x^2-4x + 4/(x-2)

we use long polynomial division here

Please check attachment for the division

The division yields 3x^2 + x - 2

what is left is to factorize the expression above

That will be;

3x^2 + 3x -2x - 2

= 3x(x + 1) -2(x + 1)

So we have (3x-2)(x + 1)

So the complete factorization will be;

3x^3-5x^2-4x + 4 = (x-2)(3x-2)(x+1)

Answer:

i think 0.28

Step-by-step explanation:

Answer:

You would pay $0.28 for 1 oz of bag of cheese

Step-by-step explanation:

$1.99 (price for 7.2 oz) ÷ 7.2 oz (how much the bag weighs) = $0.28 (rounded since the original number was: 0.2763888)

Answer:

D. As the AQL​ decreases, the​ producer's risk also decreases.

Step-by-step explanation:

The characteristic curve is the graph that shows the relation between two variables.

Operating characteristic​ curve helps in the selection of sampling plans  that are effective in reducing risks.

In case of an operating characteristic​ curve, as the AQL​ decreases, the​ producer's risk also decreases.

Option D is correct

Answer:

The graph is not a function of x because x=0 intersects the graph at two points.

Step-by-step explanation:

The vertical line test is when you draw, well, a vertical line through the graph. the slope of a vertical line is undefined, and the formula written as x=_. So we can eliminate the choices with y=_.

We can clearly see that this graph isn't a function, so we can eliminate the answer choices that say that the graph is a function.

Just in case, draw a line at x=0, to check that it does indeed cross the graph in 2 places.

Step-by-step explanation:

Answer:

y - 5 = 3(x - 1)

Step-by-step explanation:

Let the equation of the line passing through a point (x', y') and slope 'm' is,

y - y' = m(x - x')

Since slope of a line passing through two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] is represented by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of the line passing through (0, 2) and (1, 5) is,

m = [tex]\frac{5-2}{1-0}[/tex] = 3

Now equation of the line passing through a point (1, 5) and slope = 3 will be,

y - 5 = 3(x - 1)

Option (4) is the answer.

Answer:

The slope of the pile of sand is 0.5

Step-by-step explanation:

Since slope = vertical distance/horizontal distance.

Here, the vertical distance from the pile's peak to its base is 2.5 meters and the horizontal distance from its peak to its edge  is 5 meters.

So, we calculate the slope as

slope = vertical distance/horizontal distance where vertical distance = vertical distance from the pile's peak to its base = 2.5 meters and horizontal distance = horizontal distance from its peak to its edge  = 5 meters.

slope = vertical distance/horizontal

slope = 2.5 meters/5 meters

slope = 0.5

So, the slope of the pile of sand is 0.5

Answer:

carolina needs to buy at least 713 paintballs to get $10 off

Step-by-step explanation:

Entrance fee = $18

Fee per ball = $0.08

The field has a promotion that says, "Get $10 off if you spend $75 or more"

Let B represent the number of paintballs that Carolina buys.

18 + 0.08B ≥ 75

Subtract 18 from both sides

0.08B ≥ 75 - 18

0.08B ≥ 57

Divide both sides by 0.08

B ≥ 57 / 0.08

B ≥ 712.5

Approximately

B ≥ 713

carolina needs to buy at least 713 paintballs to get $10 off
