Answer:
y=3x-8
Step-by-step explanation:
Slope -intercept form is y=mx+b.
M represents the slope; b represents the y-intercept.
First, let's find the y-intercept.
It'll be found on the y-axis on the graph.
If you go down the y-axis, you'll see that -8 is the only point to be directly on the y-axis, so we can assume that that's the y-intercept.
Thus, the B in the equation is -8.
Now, let's find the slope.
You can think of it as rise over run. The rise is how many numbers the y-intercept either goes up or down until it can cross over to the x-axis. Crossing sideways is the run that's located on the x-axis.
You can begin from -8 and either count downward or upward.
For the sake of this graph, we'll go upward.
Do you see the dot on the coordinate (1,-5)?
Count upward and go to the side to get to that coordinate.
I count three upward and one to the right.
So as a fraction that would be 3 over 1 or 3/1.
But you can simplify that to just 3.
Thus, the M in the equation is 3.
Hence, y=3x-8.
Hope this helps.

Given: triangle ABC,
Angle B=120°,
AB= 6, BC = 10
Find: The area of triangle ABC
Answers
The area of triangle ABC when Angle B=120°, AB= 6, BC = 10 is 25.980 square unit.
As per the question statement, we are supposed to find out the area of triangle ABC in which angle B=120°, AB= 6, BC = 10.
Lets find out AC for which we should know about Cosine formula
i.e., [tex]AC^{2} =AB^{2} +BC^{2} -2(AB)(BC)cos(B)\\AC^{2} =6^{2} +10^{2} -2*6*10cos120\\AC^{2}= 36+100-120*(-0.5)\\AC^{2}=196\\AC=\sqrt{196} =14[/tex]
Hence We have measures of all three sides of the triangle ABC.
Now we use the Heron's formula for calculating the area of triangle ABC.
We need semi perimeter i.e., [tex]s=\frac{AB+BC+AC}{2}[/tex]
[tex]s=\frac{30}{2} =15[/tex]
Now Area is given by,
[tex]area=\sqrt{s(s-AB)(s-BC)(s-AC)} \\area=\sqrt{15(15-6)(15-10)(15-14)} \\area=\sqrt{15*9*5*1} \\area=\sqrt{675} \\area = 25.980 unit^{2}[/tex]
Area: The space occupied by an object or a shape in square units.Cosine Formula: Uses the cosine of an angle to determine the remaining sides of the triangle.Heron's Formula: Uses the measure of the all sides of triangle to calculate the area of the triangle.To learn more about Heron's questions, click on the link given below:

The amount of money raised at a fundraiser is directly proportional to the number of attendees. The amount of money raised for 12 attendees is $300. How much money is raised for 75 attendees? $300 $1,875 $900 $2,775
Answers
The amount of money raised for 75 attendees will be $1875. The correct option is B.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that the money raised for 12 attendees is $300. The money raised for 75 attendees will be calculated as below:-
12 attendees = $300
1 attendees = $300 / 12
75 attendees = $300 x 75 / 12
75 attendees = $1875
Therefore, the amount of money raised for 75 attendees will be $1875. The correct option is B.

The simplified form of the algebraic expression is [tex]\frac{23}{10} p+\frac{6}{5} r[/tex] .
An expression constructed using integer constants, variables, and algebraic operations is known as an algebraic expression in mathematics (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number).
A good example of an algebraic expression is 3x² + 2xy + c.Any expression that can be converted into a rational fraction using the properties of the arithmetic operations is said to be rational (commutative properties and associative properties of addition and multiplication, distributive property and rules for the operations on the fractions). In other terms, a rational expression is one that can be created using only the four arithmetic operations and the variables and constants.Given expression is of the form:
[tex]\frac{3}{5} (\frac{1}{2}p+2r )+2p[/tex]
Now we will use the distributive property to expand the algebraic expression:
[tex]or, (\frac{3}{5} \times\frac{1}{2}p+\frac{3}{5} \times2r) +2p\\\\or,\frac{3}{10}p+\frac{6}{5} r+2p\\ \\or,\frac{3+20}{10} p+\frac{6}{5} r\\\\or,\frac{23}{10} p+\frac{6}{5} r[/tex]

Write a difference quotient that best approximates the instantaneous rate of change of g at x=2.5.
Answers
A difference quotient that best approximates the instantaneous rate of change of g at x=2.5 is; -3
What is the Difference Quotient?We can define the average rate of change of a function g(x) in an interval [a, b] as:
r = [g(b) - g(a)]/(b - a)
Particularly, if we want to find an approximation of the rate of change for a particular value x', we can choose:
a < x' < b
Such that a and b are really close to x'.
Then if we want to find the instantaneous rate of change of g at x = 2.5, we need to find values of a and b really close to 2.5.
Looking at the graph, we can choose:
a = 2
b = 3
(are the two closer ones to 2.5)
Then the rate of change can be written as:
f'(x) = g(3) - g(2)]/(3 - 2)
f'(x) = (1 - 4)/1
f'(x) = -3
Thus, we can conclude that a good approximation of the instantaneous rate of change is -3.

now, for the denominator, the exponent -8 applies only to h. not to 4.

Using it's concept, the probability of at least 1 red face upper most is 17/18 = 0.9444 = 94.44%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For each cube, the probability of no red faces is:
Cube A: 1/6.Cube B: 3/6 = 1/2.Cube C: 4/6 = 2/3.Hence the probability of no red faces in anu cube is:
1/6 x 1/2 x 2/3 = 1/18.

The probability that the bolt will be inserted in 19 minutes or less is 0.8413.
How to calculate the probability?It should be noted that the probability will be illustrated as:
P(X < x) = P[z < (x - u/sd)]
where
x = number
u = mean
SD = standard deviation
Therefore given the numbers, this will be:
P(x < 19) = P(z < (19 - 15)/4)
= P(z < 4/4) = P(z < 1)
= 0.8413
Therefore, the probability that the bolt will be inserted in 19 minutes or less is 0.8413.
