Answer: (3,1)

Step-by-step explanation:

2x + 3y = 9

(x + 5y = 8) -2

2x + 3y = 9

-2x - 10y = -16

      -7y = -7

         y = 1

2x + 3(1) = 9

       2x = 6

        x = 3

Answer:

5.8516

Step-by-step explanation:

To find the distance between these 2 points we have to use the distance formula. The distance formula is as follows:

[tex]d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

Let's find the variables of this equation:

x2 = 6

x1 = 1

y2 = 4

y1 = 2

Now, we can plug these in to the equation:

[tex]d = \sqrt{(6-1)^2 + (4-2)^2}[/tex]

Next, let's solve:

[tex]d = \sqrt{(5)^2 + (2)^2}\\d = \sqrt{25 + 4} \\d = \sqrt{29} \\d = 5.8516[/tex]

Therefore, the distance between points (1,2) and (6,4) is 5.8516

Answer:

5/12

Step-by-step explanation:

Total pound of oranges = 5

Number of piles = 12

Weight of the oranges in each pile = Total pound of oranges / Number of piles

= 5 / 12

The rational number which represents the weight of the oranges in each pile is 5/12

Answer:

This means that the width = 3y²

The length = 4y+7y³

Step-by-step explanation:

Given

Area of the rectangle = 12y^2+21y^5

Width of the rectangle is the greatest common monomial of 12y^2 and 21y^5

First let us get the greatest common monomial of 12y^2 and 1^5

12y^2 = (3  * y * y) * 4

21y^5 = (3 * y*y)*y*y*y* 7

Hence the greatest common monomial is 3 * y * y = 3y²

Factor out 3y² from the area function;

12y^2+21y^5

3y² (4y+7y³) = Area of the rectangle

Length * Width = 3y² (4y+7y³)

On comparing both sides of the equation

This means that the width = 3y²

The length = 4y+7y³

Answer:

4y^2

Answer:

m=41/24

Step-by-step explanation:

The slope of the line passing through the points (12, 1), (36, 42) is m=41/24.

To find slope, we need to use the slope formula*.

42 - 1/36 -12 = 41/24

m = 41/24

Answer:

Option A: f(x) = log_0.98 (n/74)

Step-by-step explanation:

We are told that that the number of species is decreasing by 2% per year.

Thus, number of species each year is 98% or 0.98 of number of species the previous year. .

We are told that there are currently 74 species of amphibians in the rain forest.

Thus, n/74 will represent a fraction of the current number of species.

Thus, the logarithmic function that models the time can be written as;

f(x) = log_0.98 (n/74)

Answer:

A. f(n) = log0.98(n/74)

The subtraction expression that has the difference 1 + 4i is (3 + 5i) - (2 + i).

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can find the difference 1 + 4i by subtracting the complex numbers in each expression and checking which one gives us the result of 1 + 4i.

Let's start with option (a):

(-2 + 6i) - (1 - 2i) = -2 + 6i - 1 + 2i = -3 + 8i

This is not equal to 1 + 4i, so option (a) is not the correct answer.

Let's move on to option (b):

(-2 + 6i) - (1 - 2i) = -2 + 6i - 1 + 2i = -3 + 8i

We have already seen this expression and it is not equal to 1 + 4i. Therefore, option (b) is also not the correct answer.

Let's move on to option (c):

(3 + 5i) - (2 - i) = 3 + 5i - 2 + i = 1 + 6i

This is not equal to 1 + 4i, so option (c) is not the correct answer.

Finally, we have the option (d):

(3 + 5i) - (2 + i) = 3 + 5i - 2 - i = 1 + 4i

This is equal to 1 + 4i.

Thus,

The subtraction expression that has the difference 1 + 4i is (3 + 5i) - (2 + i).

Step-by-step explanation:

Answer:Answer: The value of x is 11 and the measure of each sides are, 74 cm,74 cm and 37 cm. Explanation: It is given that in triangle CDE is an isosceles triangle with CD congruent to DE. If CD equals 9x - 25, DE equals 6X + 8, CE equals 10 x - 73.

Step-by-step explanation:

Answer:

x=11

Step-by-step explanation:

First, you would subtract the x from both sides to get -4y=8-x. Then you divide by -4 to get y=-2+1/4x. You rearrange your answer to get y=1/4x-2. Then you would graph starting at negative two on the y-axis, or the vertical line, and then go up 1 and over 4 to draw the next dot. Hope this helps!

Answer:

n = number of nickels = 7

d = number of dimes = 10

p = number of pennies = 20

Step-by-step explanation:

Let

n = number of nickels

d = number of dimes

p = number of pennies.

n + d + p = 37

0.05n + 0.10d + 0.01p = 1.55

p = 2d

Substitute p = 2d into the equation

n + d + 2d = 37

0.05n + 0.10d + 0.01(2d) = 1.55

n + 3d = 37

0.05n + 0.10d + 0.02d = 1.55

n + 3d = 37 (1)

0.05n + 0.12d = 1.55 (2)

Multiply (1) by 0.05

0.05n + 0.15d = 1.85

0.05n + 0.12p = 1.55

Subtract

0.15d - 0.12d = 1.85 - 1.55

0.03d = 0.3

d = 0.3/0.03

= 10

d = 10

p = 2d

= 2(10)

p = 20

n + d + p = 37

n + 10 + 20 = 37

n + 30 = 37

n = 37 - 30

n = 7

n = number of nickels = 7

d = number of dimes = 10

p = number of pennies = 20
