Step-by-step explanation:

Answer:

In equation A, x= -1 and y= 3

In equation B, x= 12 and y= 16

Step-by-step explanation:

Given the expression

(x + yi) + (4 – 7i) = 3 – 4i

We are to find the value of x and y

Expand the equation;

(x + yi) + (4 – 7i) = 3 – 4i

x + yi + 4 – 7i = 3 – 4i

x+4+yi-7i = 3 - 4i

x+4 + (y-7)i = 3-4i

Equate the real part

x+4 = 3

x = 3-4

x = -1

Equate the imaginary part;

y - 7 = -4

y = -4 + 7

y = 3

In equation A, x= -1 and y= 3

For equation B:

(x + yi) - (-6 + 14i) = 18 + 2i

x+yi+6-14i = 18+2i

x+6+(y-14)i = 18+2i

x+6 = 18

x = 18-6

x = 12

Equate the imaginary part;

y - 14 = 2

y = 2 + 14

y = 16

Hence In equation B, x=12 and y= 16

Answer:

One serving of Grapefruit juice has 41 more mg of Vitamin C than one serving of Tomato juice

Step-by-step explanation:

This question is asking for a comparison of the amount of Vitamin C is Grapefruit juice, 86 mg, and Tomato juice, 45 mg. Because the question is worded so that whichever juice has the most Vitamin C is put first, Grapefruit juice must be put first. The next part is asking for the difference in the amount of Vitamin C between Grapefruit and Tomato juice, which can be found by simplifying an expression such as 86-45. This leaves the answer being 41, which will be put in the second box. Finally, the third box is asking for the juice with the lowest amount of Vitamin C, which is the tomato juice.

im getting alot of points thank you:)))...the reason I am going this is cause you are doing the same thing

The answers for both the parts are a) 260 and b) 200 Jolly Rancher and 520 jawbreakers.

A ratio is a way to show a relationship or compare two numbers of the same kind. We use ratios to compare things of the same type.

Given that, a candy jar have candies type Jolly Rancher and jawbreakers

in ratio 5:13 respectively.

Let the number of Jolly Rancher and jawbreakers be 5k and 13k respectively,

a) When you have 100 Jolly Rancher, then,

5k = 100

k = 20

Hence, number of jawbreaker = 20×13 = 260

b) When the total number of candies in the jar is 720, then,

5k+13k = 720

18k = 720

k = 40

Therefore, number Jolly Rancher and jawbreakers it contains = 40×5 = 200 and 13×40 = 520

Hence, The answers for both the parts are a) 260 and b) 200 Jolly Rancher and 520 jawbreakers.

I had the same question, not sure if you still need it.

Answer:

Quantity A because it changes with gravitational pull.

Explanation:

Mass defines the constitutive matter of an object. It is immutable (does not change). Although it could be converted into energy, the matter is constant.

On the other hand, the weight of an object (gravitational force) depends on the acceleration due to gravity.

That is why an astronaut weighs about three times more on earth than on Mars. The gravitational acceleration on Mars is about one third that on earth.

Please check the attached number line graph.

The number line clearly indicates that the graph is heading towards negative infinity from -2.

Step-by-step explanation:

Given the inequality expression

x ≤ -2

The inequality symbol ' ≤ ' means 'less than or equal to'.

Thus,

x ≤ -2 means x is less than or equal to -2.

In other words,

[tex]x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}[/tex]

Answer:

  A.  d = 0 -- one (1) solution

  B.  x = {1, 3.5}

Step-by-step explanation:

A. The discriminant for ax²+bx+c = 0 is ...

  d = b² -4ac

For the given equation, this is ...

  d = (-36)² -4(9)(36) = 0

The discriminant is zero (0).

The discriminant divided by the leading coefficient (a=2) will give the difference between the two roots of the equation. When the difference is zero, as here, both roots are the same. Effectively, there is one (1) solution to the equation.

__

B. The equation can be factored as ...

  2x² -9x +7 = (2x -7)(x -1) = 0

The solutions are the values of x that make the factors be zero:

  2x -7 = 0  ⇒  x = 7/2

  x -1 = 0  ⇒  x = 1

  The solutions are x = 7/2  or  x = 1.

Answer:

The possible lengths of c are between 3 to 17.

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

a = 7

b = 10

As we know that, in a triangle length of third side is always greater than difference between the given two side, and always lesser than sum of both side.

So, Difference between both side = 10 - 7 = 3

Sum of both side = 10 + 7 = 17

Hence, the possible lengths of c are between 3 to 17.

Answer:

y+2=.25(x+3)

Step-by-step explanation:

The point slope form is shown as follows

y-y₁=m(x-x₁)

We know that the slope (m) is equal to .25 and that x₁=-3 and y₁=-2

We can plug this in and get

y-(-2)=.25(x-(-3))

Simplify the signs to get

y+2=.25(x+3)

Answer:

139, or 140. I did the math, but i am not entirely sure

Step-by-step explanation:

Answer:

3 units

4 1/2 or - 1 1/2

Step-by-step explanation:

Given that :

Value of n is a distance of 3 units from 1 1/2 on a number line.

Recall that a number line may be divided into two parts that is the left and righmosr portions with 0 as the mid point.

Hence a value of 3 units from 1 1/2 may be to the right (positive) or to the left(negative side of the line).

Therefore :

1 1/2 + 3 = 4 1/ 2

1 1/2 - 3 = - 1 1/2

The value n will result in a distance of 3 units in either way and could be either 4 1/2 or - 1 1/2

When multiplying the same number is raised to different exponents add the exponents together:

332^-6 x 332^3 = 332^(-6 +3) = 332^-3

Then when a number is raised to a negative exponent, change the exponent to a positive value and make the number a fraction, as the denominator, with 1 as the numerator:

332^-3 = 1/332^3

1/332^3 = 1/36594368

Answer:

-248.15°C

Step-by-step explanation:

An object in a laboratory is cooled to 25 Kelvin. What is the temperature of the object in degrees Celsius?

The formula that converts from Kelvin to degrees Celsius =

Celsius = (Kelvin – 273.15)

Kelvin = 25K

Hence:

°C = 25 - 273.15

°C = -248.15°C

Therefore, the temperature of the object in degrees Celsius is -248.15°C
