Do you need a equation for that?

y=4x+3

Answer:

r = -13

Step-by-step explanation:

Step 1: distribute the signs & terms outside the parenthesis. on the left side, distribute a - sign (same thing as -1) and on the right side distibute -7

12 - (3r) - (+2) = (-7)r + (-7)6

Step 2: algebraically simplify

10 - 3r = -7r - 42

52 = -4r

r = -13

Answer:

The ones you circled are right I believe its just small errors in your notations. I am not sure if the justifications are correct or not.

4 might just be a labelling of the line error. Say line AD is parallel to line BE and line AC is parallel to BD

6 all the lines you circled are all parallel to each other, not two separate pairs

The equation isn't written out so I can't be sure but here are possible answers.

2.2 divided by 6 is 0.36. 0.36 minus 2 is -1.64.

6 minus 2 is 4. 2.2 divided by 4 is 0.55.

Step-by-step explanation:

m∠3 = 7x - 10

m∠6 = 5x + 10

m∠3 = m∠6

7x - 10 = 5x + 10

7x - 5x = 10 + 10

2x = 20

x = 20/2 = 10°

Answer:

132

Step-by-step explanation:

The required answer would be the sum of 5, and 4 is divided by 2 as per the PEMDAS rule which is the correct answer would be option (A)

PEMDAS rule states that the order of operation starts with the calculation enclosed in brackets or the parentheses first. Exponents (degrees or square roots) are then operated on, followed by multiplication and division operations, and then addition and subtraction.

We have been given that expression as

⇒ 5 + 4 ÷ 2

As per the PEMDAS rule,

We have to apply the division operation to terms 4 and 2,

⇒ 5 + 4 /2

⇒ 5 + 2

Apply the addition operation, and we get

⇒ 7

Therefore, the required answer would be the sum of 5, and 4 is divided by 2.

Answer:

The radius is half one of the sides.

Step-by-step explanation:

Answers:

==========================================================

Explanation:

In triangle P, aka triangle ABC, we have the color coded angles:

For triangle Q, aka triangle XYZ, we have:

The colors must pair up to match together. The order is important. That order being "blue, purple, red".

Because of this, we have the three pairs of congruent angles:

Furthermore, that extends to having these pair of corresponding sides that match up together:

-----------------------

Side AC = 7 involves the blue and red angles. The same applies to XZ = 21.

The jump from 7 to 21 is "times 3", which tells us the scale factor. The triangle XYZ has side lengths 3 times longer compared to triangle ABC.

We'll use this scale factor to determine the missing sides of each triangle.

-----------------------

Side BC = 5 involves the purple and red angles. For the other triangle, side ZY involves those same color angles. Going from BC = 5 to ZY = unknown will involve the "times 3" operation. So we have,

ZY = 3*BC = 3*5 = 15

-------------------------

Side AB = unknown pairs up with side XY = 27 of the other triangle. Each side mentioned involves the blue and purple angles.

Instead of multiplying, we'll do the opposite: we divide 27 by 3 to get the side of AB.

This is because:

XY = 3*AB

AB = XY/3

AB = 27/3

AB = 9

The value of P(B|A) is 0.25.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have P(A) = 0.40 and P(B) = 0.5

and, P(A and B) = 0.10

Using Conditional Probability

P(B|A) = P(A ∩ B)/P(A)            

Substitute the values of P(A), P(B) and P(A ∩ B),

P(B|A) = 0.10/ 0.40

P(B|A) = 0.25

Step-by-step explanation:

that's an equilateral triangle, 3 equal side and 3 equal angles of 60°,

so 10x + 20 = 60

solve with an equation

10x + 20 = 60

10x = 60 - 20

10x = 40

An exponential decay function that represents the population after t years is [tex]\rm f (x) = 250000 (0.965)^t[/tex].

An exponential function can be represented in the form f(x) = aˣ.

The population of a city was 250,000

Rate of decay is 3.5%

Two or more expressions with an Equal sign is called as Equation.

Given that,

f ​is a scaled copy of Figure e

The process of increasing or decreasing a figure with a factor is called as scaling.

Given that segment AB=6

Answer:

The distance is 4 units.

Step-by-step explanation:

Let the distance between the two points (x₁, y₁) and (x₂, y₂) is

d = √(x₂ - x₁)² + (y₂ - y₁)²

Here, the given points are (2,8) and (6,8), therefore,

x₁ = 2, x₂ = 6,

y₁ = 8, y₂ = 8

d = √(x₂ - x₁)² + (y₂ - y₁)²

d = √(6 - 2)² + (8 - 8)²

d = √(4)² + (0)²

d = √16

d = 4

Thus, The distance is 4 units.
