The exterior angle of a triangle is equal to the sum of the interior angles

6x+1 = 79+ 2x+10

Combine like terms

6x+1 = 2x+89

Subtract 2x from each side

4x+1 = 89

Subtract 1 from each side

4x = 88

Divide by 4

For the fractions, the calculation of 3/5 of 2/3 of 3/4 of 560 is equal to 168.

To calculate 3/5 of 2/3 of 3/4 of 560, break it down step by step:

Step 1: Calculate 3/4 of 560:

3/4 × 560 = (3 × 560) / 4 = 1680 / 4 = 420

Step 2: Calculate 2/3 of the result from Step 1:

2/3 × 420 = (2 × 420) / 3 = 840 / 3 = 280

Step 3: Calculate 3/5 of the result from Step 2:

3/5 × 280 = (3 × 280) / 5 = 840 / 5 = 168

Therefore, 3/5 of 2/3 of 3/4 of 560 is equal to 168.

Step-by-step explanation:

Two equations:

x = 5 + 4y

x + y = 40

Substitute x for 5 + 4y:

5 + 5y = 40

5y = 35

y = 7

Substitute y for 7:

x = 5 + 4(7)

The answer is 90° counterclockwise

Step-by-step explanation:

Have a good day

The rotation that maps point K(8, 6) to K(-6, 8) is 90° counterclockwise rotation

The coordinates are given as:

K(8, 6) to K(-6, 8)

Remove the points

(8, 6) to (-6, 8)

Replace the coordinates with x and y

(x, y) to (-y, x)

The above represents a 90° counterclockwise rotation

Hence, the rotation that maps point K(8, 6) to K(-6, 8) is 90° counterclockwise rotation

Answer:

average rate of change is 3/2

Step-by-step explanation:

Recall that the average rate of change in an interval [x1, x2], is defined as:

[f(x2)-f(x1)] / (x2 - x1)

which for the interval [0, 2] becomes:

[f(2)-f(0)] / (2 - 0)

From the graph we read that f(0)= 1 and f(2) = 4, therefore:

[f(2)-f(0)] / (2 - 0) = [4 - 1] / 2 = 3/2

Angie decorates 8 cupcakes after putting 4 sugar flowers on each cupcake.

To find the number of cupcakes c Angie decorates, we can use the equation:4c = 32where 'c' is the number of cupcakes Angie decorates.

4 represents the number of sugar flowers Angie puts on each cupcake, and 32 is the total number of sugar flowers Angie puts on the cupcakes.

To solve this equation for c, we need to isolate c on one side of the equation. We can do this by dividing both sides of the equation by 4. This gives us:c = 8

Therefore, Angie decorates 8 cupcakes.Here's how we get to this answer:4c = 32Divide both sides by 4 to isolate c:c/4 = 32/4c = 8

Case 1: a = 0; b = 0 --> Real Number

Case 2: a = 0; b ≠ 0 --> Non-Real Complex Number

Case 3: a ≠ 0; b = 0 --> Real Number

Case 4: a ≠ 0; b ≠ 0 --> Non-Real Complex Number

For each case, we can determine whether the expression a + bi represents a real number or a non-real complex number based on the values of a and b.

Case 1: a = 0; b = 0

In this case, both a and b are zero. The expression a + bi simplifies to 0 + 0i, which is equal to 0. Therefore, the expression represents a real number.

Case 2: a = 0; b ≠ 0

Here, a is zero, but b is nonzero. The expression a + bi becomes 0 + bi, where b is a nonzero real number multiplied by the imaginary unit i. Since the expression contains a nonzero imaginary part, it represents a non-real complex number.

Case 3: a ≠ 0; b = 0

In this case, a is nonzero, but b is zero. The expression a + bi simplifies to a + 0i, which is equal to a. As there is no imaginary part in the expression, it represents a real number.

Case 4: a ≠ 0; b ≠ 0

Here, both a and b are nonzero. The expression a + bi contains both a real part (a) and an imaginary part (bi). Thus, it represents a non-real complex number.

The product of the two numbers  45, is the highest number, and the sum of the two numbers  18, is the lowest number follow symmetry .

When an object is split into two identical, mirrored components, it is said to have symmetry in mathematics. What does "axis of symmetry" refer to? An "axis of symmetry" is a fictitious line that has the ability to fold or split a thing into two identical mirror parts. Any object is symmetrical if two parts fit together. To determine the shape's symmetry, draw a mirror line across the center, making sure that all parts are identical. Another way of putting it is that symmetry is when two objects are facing one another or when two items have mated components that circle around an axis.

The reasoning presented lacks explicit explanations and logical connections between the steps, making it difficult to fully understand the intended proof strategy.

The given proof aims to show that the Separation Axioms can be derived from the Replacement Schema using a particular construction involving a formula p(x, y). Let's analyze the proof step by step:

Define the formula p(x, y) as x = yo(x).

This formula states that for each x, y pair, x is equal to the unique object y such that y is obtained by applying the operation o to x.

Define the set F as {(x, x) (x)}.

This set F contains pairs (x, x) where x is the unique object obtained by applying the operation (x) to x.

Claim: F(X) = {y (x = X)p(x, y)} = {y: (x = X)x = y^o(x)} = {x: (3x € X)o(x)} = {x X: (x)}.

This claim asserts that F(X) is equivalent to {y (x = X)p(x, y)}, which is further equivalent to {y: (x = X)x = y^o(x)}, and so on.

The proof states that since (x, y) satisfies the functional formula VaVyVz(p(x, y)^(x, z) y = z), it follows that (x, y) is a functional formula.This step emphasizes that the formula p(x, y) satisfies certain properties that make it a functional formula, which is relevant for the subsequent deductions.

Finally, the proof concludes that the Separation Axioms follow from the Replacement Schema, based on the previous steps.

Step-by-step explanation:

use Pythagorean theorem:

a² + b² = c²

where a = h

plugin values into the formula:

h² + 4² = 5²

x = √9

x = 3

The value of f(2) in the given algebraic expression is:  18

The algebraic expression we are given is expressed as:

f(x) = 2x² + 5√(x + 2)

Now, we want to find f(2) which means we want to find the range when the domain is x = 2. Therefore we solve it as:

f(2) = 2(2)² + 5√(2 + 2)

f(2) = (2 * 4) + 5√4

f(2) = 8 + 5√4

f(2) = 8 + (5 * 2)

f(2) = 8 + 10

The meaning of the derivative f'(8) is the rate of change of the quantity of coffee sold with respect to the price per pound when the price is $8 per pound.

It represents how the quantity of coffee sold changes with respect to changes in the price per pound, when the price per pound is $8.

In mathematics, the derivative of a function is a measure of how the value of the function changes with respect to changes in one of its variables. In other words, the derivative gives the rate of change of a function with respect to its independent variable.

The derivative can be thought of as the slope of the tangent line to the function at a particular point. It can be calculated using limits, differential calculus, or other methods. The derivative is represented by the symbol "d/dx" for a function of a single variable x, where d/dx represents the rate of change of the function with respect to x.

The value of x, representing the length of the hypotenuse AC, is 3√2 units.

In a right triangle ABC, with angle ABC measuring 45 degrees and side AB having a length of 3 units, we can use trigonometric ratios to find the length of the hypotenuse AC, represented by x.

Since angle ABC is 45 degrees, we know that it is a special right triangle, specifically a 45-45-90 triangle.

In such a triangle, the lengths of the sides are in a specific ratio: 1:1:√2.

In this case, side AB is 3 units, which represents the length of one of the legs. By the ratio mentioned earlier, the hypotenuse AC (x) will be √2 times the length of AB.

Therefore, we have:

AC = AB \(\times\) √2

AC = 3 \(\times\) √2

AC = 3√2 units
