ANSWER: 47 .....................................................................................................................................................................................

Answer:

4 + 4i

Step-by-step explanation:

Add the real part and add the imaginary part.

9 + 7i + (-5  - 3i) = 9 + 7i - 5 - 3i

                          = 9 - 5 + 7i - 3i

                          = 4  + 4i

Answer:

44

Step-by-step explanation:

Okay so we are given (9 + 71) + (-5 - 31).

We need to figure out the value of this expression.

First, let's solve the expression (9 + 71).

1.  (9 + 71) = 80.

Now we have 80 + (-5 - 31).

Next, let's solve the expression (-5 - 31).

2.  (-5 - 31) = -36.

We're left with 80 + (-36).

Finally, let's add the two numbers together.

80 + (-36) = 44

So (9 + 71) + (-5 - 31) = 44

Answer:

1-7 2-6 3-6 4-4

Step-by-step explanation:

To do this, you must notice that all of these are isosceles triangles (2 of the sides are the same.) You already have 1 value on each triangle, and the length of that side is the same length as the side with the unknown value, so those are the correct answers. If I made a mistake, please correct me. Everybody makes mistakes.

The slope is the intensity of inclination thus the slope of p(x) is greater than the slope of m(x) thus option (A) is correct.

A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.

As per the given function,

p(x) = 157.1x

p(x)/x = slope = 157.1

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

In the function m(x) the slope will be as,

Slope = (188.4 - 125.6)/(3 - 2)

Slope = 62.8

Hence "The slope is the intensity of inclination thus the slope of p(x) is greater than the slope of m(x)".

Y = 20

Step-by-step explanation:

120/ 160 = 15 / y

120/15=8

that means there is a 8 to 1 ratio between them. So now do 160/8 = y

y = 20.

prove it by dividing both fractions to create decimal form. They match, so y = 20.

Answer:

62 cm^2

Step-by-step explanation:

the sides are 3*5, 3*2, and 2*5, and there are two of each. 3*5 is 15, 3*2 is 6, and 2*5 is 10.

we need to find 15*2, which is 30, 6*2, which is 12, and 10*2 which is 20. then we need to add all of these together, which is 62

Answer:

angle A is congruent to angle R

Step-by-step explanation:

when it gets rotated counterclockwise around point X that is how the triangles end up matching up

Answer:

The answer is 1. ∠A ≅ ∠R

Step-by-step explaation:

Looking at the triangles when they're in their alphabetical order, ΔABC and ΔRST, since they are congruent, that means that if you were to pick an angle in one triangle, it would be equal to the angle in the same place of the other triangle. So if we were to take the first letter from ΔABC it'd be A, and the first letter in ΔRST is R, so that means angles ∠A and ∠R should be congruent.

Answer:

13

Step-by-step explanation:

First find the population of city c 1,070,000 times 2 = 2140000

Round 2140000 to the nearest hundred thousands = 2,100,000

Third find how many places the decimal moves which is 6 places

Fourth scientific notation of 2,100,00 is 2.1 times 10^6

Fifth divided city c by the population of city a

2.1x 10^6 divided by 1.6 x 10^5

2.1 / 1.6 rounded is 1.3

10^6 divided by 10 ^ 5 is 10

Therefore 2.1 x 10^6 divided by 1.6 divided by 10^5 equals 1.3 times 10 = 13

The population of city c is about 13 times the population of city a

Answer:

Point A

Step-by-step explanation

Got it correct on edge test

Point A represents (3, - ). Therefore, the correct option is option A among all the given options.

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more integers, or coordinates. It matters how the coordinates are arranged.  

Sometimes they are recognised by their place in an ordered tuple, and other times they are recognised by a letter, such as "the x-coordinate." In elementary mathematics, the coordinates are assumed to be real numbers. Point A t represents (3, - ).

Therefore, the correct option is option A.

Answer:

no solution

Step-by-step explanation:

1/2(2-4x)+2x=13

We simplify the equation to the form, which is simple to understand

1/2(2-4x)+2x=13

Simplifying:

+ 0.5*(2-4x)+2x=13

Reorder the terms in parentheses

+(+1-2x)+2x=13

Remove unnecessary parentheses

+1-2x+2x=+13

We move all terms containing x to the left and all other terms to the right.

-2x+2x=+13-1

We simplify left and right side of the equation.

0x=+12

0=12

The left and right sides are not equal, therefore there is no solution. This equation is invalid.

Answer:

✔ 3r > 34

✔ r > 11.3

✔ The squirrel ran faster than 11.3 feet per second.

Step-by-step explanation:

1. The Squirrel's speed is 3r > 34

2. The solution of the inequality is r > 11.3

3. The interpretation is: The squirrel ran faster than 11.3 feet per second.

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

A squirrel runs across a road in 3 seconds.

The road was more than 34 feet wide.

1. The Squirrel's speed is

3r > 34

2. The solution of the inequality is

r > 34/3

r > 11.3

3. The interpretation is: The squirrel ran faster than 11.3 feet per second.

Answer:

Marcel reads 20 pages every 2 days.

Then, in one day, she reads:

20/2 = 10 pages per day.

Now, we know that in one day she reads 10 pages, then we can subdivide the number 350 in N groups of 10 pages, each one of these N groups needs one day to be read, then 350 pages will be read in N days:

N = 350/10 = 35 days.

Xion reads 8 pages per day.

Then to read 350 pages, he neds:

N = 350/8 = 43.75 days

Amber reads 56 pages in 7 days.

Then she reads 56/7 = 8 pages per day (Same as Xion)

Then she also needs 43.75 days to read 350 pages.

Francessca reads 55 pages in 5 days.

Then she reads 55/5 = 11 pages per day.

To read 350 pages, she needs:

350/11 = 31.82 days

Then the one that needs less days to read 350 pages is Francessca.
