Find the equation of the linear function represented by the table below in
slope-intercept form.
V
5
-10
8
A linear function in slope intercept form is
y = mx + c
To find the equation, you need m and c. This can be found by substituting the points you have.
For example, 5 = -1(m) + c and -7 = 2(m) + c
From here, do simultaneous equations
c = m + 5
-7 = 2(m) + m + 5
3m = -7 -5
m = -4
c = m + 5
c = 1
Rewrite the equation: (This is your answer)
y = -4x + 1
A bag contains 7 milk and 5 dark chocolates. A sweet is selected at random. What is the probability of choosing: P(milk) = P(not milk) =
Answer: P(7)=P(5)=12
Step-by-step explanation:
The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
A sack contains 7 milk and 5 dim chocolates. A sweet is chosen indiscriminately.
The total number of the sweets will be given as,
Total events = 7 + 5 = 12
The probability of choosing milk will be given as,
P = (7/12)
P = 0.5833
The probability of choosing not to milk will be given as,
P = (5/12)
P = 0.4167
The probability of choosing milk and not milk will be 0.5833 and 0.4167, respectively.

express x^2 - 8x + 5 in the form (x - a)^2 - b where a and b are integers
Answer:
x^2 -8x + 5 = (x-4)^2 - 11
Step-by-step explanation:
Here we want to write the given expression in the form
x^2-8x + 5 can be written as follows;
(x-4)^2 = x^2 - 8x + 16

What is pattern?A recurring arrangement of numbers, forms, colours, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series.
From the given pattern,
Area of the shape in step 1 is 2 square centimeter
Area of the shape in step 2 is 7 square centimeter
Area of the shape in step 3 is 14 square centimeter
Here, the pattern is 2²-2=2
3²-2=7
4²-2=14
so, the general form is (n+1)²-2
Therefore, the area of the shape in Step n is (n+1)²-2.

HELP In △ABC, m∠A = 75° and m∠C = 20°, What is m∠B?
To solve this question, we must know the the angle sum property of a triangle. Therefore the value of ∠B is 85° when ∠A = 75° and ∠C=20° in △ABC
What is angle sum property of a triangle?According to angle sum property of a triangle, the sum of all angles of a triangle is always 180 degree. It can never be more than or less than 180 degree. If two angles of a triangle is given then the third angle can be calculated by subtracting the sum of two angle from 180°
The sum of the three angles in a triangle = 180° , that is
∠ A + ∠ B + ∠ C = 180°
Substituting the given values in the given equation we get
75° + ∠ B + 20° = 180°
∠ B + 95° = 180°
subtracting 95° from both sides we get
∠ B = 85°
Therefore the value of ∠B is 85° when ∠A = 75° and ∠C=20° in △ABC

Nigel and Mia are searching for a treasure chest under water. The straight line distance between them is 100 meters.
A triangle has points Nigel, Mia, and Treasure Chest. The distance from Nigel to Mia is 100 meters. The angle between Treasure Chest, Nigel, and Mia is 65 degrees. The angle between Nigel, Mia, and Treasure Chest is 80 degrees.
Given the angles in the diagram, who is closer to the treasure chest and why?
Nigel is closer because his distance to the chest is opposite the larger angle.
Mia is closer because her distance to the chest is opposite the smaller angle.
Nigel is closer because his distance from the chest is 100 meters.
Mia is closer because her distance from the chest is 100 meters.
Mia is closer to the treasure chest because her distance to the chest is opposite the angle less than 80 degrees.
What is triangle?A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°

The measure of angle R is 3 degrees less than twice the measure of angle S. If the sum of the measures of the two angles is 72 degrees, find the measure of each angle.
Measures of the given angles:
∠S = 25° and ∠R = 47°
What is an angle?In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.
There are two main parts related to an angle - the arms and the vertex.
Given,
Measure of angle R is 3 degrees less than twice the measure of angle S
⇒ 2∠S - ∠R = 3°
⇒ ∠R = 2∠S - 3° ------(a)
Sum of R and S
⇒ ∠R + ∠S = 72°
Substituting ∠R in terms of ∠S in above equation from equation (a)
2∠S - 3° + ∠S = 72°
3∠S - 3° = 72°
3∠S = 72° + 3°
3∠S = 75°
∠S = 75°/3
∠S = 25°
Substituting value of ∠S in equation (a)
∠R = 2 × 25° - 3°
∠R = 50° - 3°
∠R = 47°
Hence, ∠S = 25° and ∠R = 47° are the measures of given angles.

Use the Law of Cosines to write an expression equivalent to a. I need this answer urgently pls!
9514 1404 393
Answer:
a = √(b² +c² -2bc·cos(A))
a = √(c² -b²)
Step-by-step explanation:
For sides a, b, c, and opposite angles A, B, C, the general form of the law of cosines is ...
a² = b² + c² -2bc·cos(A)
An expression for 'a' can be written by taking the square root.
a = √(b² +c² -2bc·cos(A))
__
If you recognize that cos(A) = b/c, then a substitution can be made:
a = √(b² +c² -2(bc)(b/c)) = √(b² +c² -2b²)
a = √(c² -b²) . . . . . . . same as the Pythagorean theorem
