Answer:
y= -1/4x - 6
Step-by-step explanation:
slope: rise over run
find a clear point such as (-4, -5) and count how many to the right and how many down so that you get to the point where it crosses the y-axis (0, -6).
so it is 1 down, and 4 across, giving you slope of -1/4. It is negative because it is going downwards.
as for the +b, it is the y value where it crosses the y axis. (0, -6). so you get -6

the steps alana used to solve the equation x - 7 equals 18 are shown drag a reason for each step to the table
The steps Alana used to solve the equation x - 7 = 18 are:
Step 1: Add 7 to both sides to isolate x: x - 7 + 7 = 18 + 7.
Step 2: Simplify and solve for x: x = 25.
Alana used the following steps to solve the equation x - 7 = 18:
Step 1: Add 7 to both sides to isolate x: The reason for adding 7 to both sides is to eliminate the constant term (-7) from the left-hand side of the equation and to move it to the right-hand side. By doing so, Alana isolates the variable term (x) on the left-hand side and obtains x = 18 + 7.
Step 2: Simplify and solve for x: The reason for simplifying the right-hand side of the equation is to obtain the value of x that makes the equation true. By adding 18 and 7, Alana gets 25, which is the solution to the equation.
In summary, Alana used the addition property of equality to add the same value to both sides of the equation, in order to isolate the variable term and solve for x.

if the ^abc is 32, and the ^dba is 143 find ^aoc and ^ocd
Examining the figure, the missing angles are
angle AOC = 148 degrees
angle OCD = 21 degrees
How to find the anglesLine AB and CB are tangents to the circle and hence will make angle 90 degrees at the point of tangent.
OA bisects angle AOC and angles ABC
In triangle AOB
90 + 32/2 + angle AOB = 180 degrees
angle AOB = 180 - 90 - 32 / 2
angle AOB = 74 degrees
angle AOC = 74 x 2 = 148 degrees
Using inscribed angle theorem
angle D = 1/2 x angle AOC
angle D = 74 degrees
In quadrilateral ABCD
143 + 32 + 74 + angle C = 360
angle C = 360 - 143 - 32 - 74
angle C = 111 degrees
angle OCD = 111 - 90

Find the value of x.
A family decides to have children until it has three children of the same gender. assuming p(b) = p(g) = 0. 5, what is the pmf of x = the number of children in the family?
The pmf provides the probabilities of having 1, 2, or 3 children in the family based on the condition that the family stops having children once it has three children of the same gender.
To find the probability mass function (pmf) of the number of children in the family, we need to consider the possible values of x (the number of children) and their corresponding probabilities.
Let's analyze the possibilities:
1. x = 1 (only one child): The probability of having either a boy or a girl is 0.5. Therefore, P(x=1) = P(B or G) = 0.5.
2. x = 2 (two children): The possible outcomes are BB, GG, or BG (in any order). Each of these outcomes has a probability of 0.5 * 0.5 = 0.25. Therefore, P(x=2) = P(BB or GG or BG) = 0.25 + 0.25 + 0.25 = 0.75.
3. x = 3 (three children): The only outcome that satisfies the condition is BBB or GGG (in any order). Each of these outcomes has a probability of 0.5 * 0.5 * 0.5 = 0.125. Therefore, P(x=3) = P(BBB or GGG) = 0.125 + 0.125 = 0.25.
From the above analysis, we have:
P(x=1) = 0.5
P(x=2) = 0.75
P(x=3) = 0.25
To summarize, the pmf of x (the number of children in the family) is:
P(x=1) = 0.5, P(x=2) = 0.75, P(x=3) = 0.25.
The pmf provides the probabilities of having 1, 2, or 3 children in the family based on the condition that the family stops having children once it has three children of the same gender.

x + y = -5 is it a solution
Answer: The equation X + y = -5 represents a straight line in a two-dimensional plane. To determine whether a specific point (X, y) is a solution of the equation, you can substitute the values of X and y into the equation and see if it holds true. If the equation is satisfied, then the point (X, y) is a solution. If the equation is not satisfied, then the point (X, y) is not a solution.
For example, if X = 2 and y = -7, then the equation becomes:
2 + (-7) = -5
-5 = -5
Since the equation holds true, the point (2, -7) is a solution of the equation X + y = -5.

Find the M JLN
Geometry problem from a test
The value of measure of angle JLN is,
⇒ m ∠JLN = 65 degree
An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Since, WE know that;
The value of angle is half of the difference between major and minor arc of a circle.
Hence, We can formulate;
⇒ m ∠JLN = 1/2 (180 - 50)
⇒ m ∠JLN = 1/2 (130)
⇒ m ∠JLN = 65 degree
Therefore, The value of measure of angle JLN is,

how many liters of water must be added to 50 liters of a 25% acid solution in order to produce a 30% acid solution?
Using equations we know that approximately 8 liters of water must be added in order to produce a 30% acid solution.
What are equations?Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.So, we know that:
Liters of water: x
25% of solution: 0.25 × 50
30% of solution: 0.30 (50 + x)
Now, form equations and calculate as follows:
0.25 × 50 = 0.30 (50 + x)
12.5 = 15 + 0.30x
15 + 0.30x = 12.5
15 + 0.30x - 15 = 12.5 -15
0.30x = -2.5
.030x/.30 = -2.5/.30
x = - 8.33
Since we can't add water in negative, hence it will be +.
Rounding off: 8 liters
Therefore, using equations we know that approximately 8 liters of water must be added in order to produce a 30% acid solution.

A seventh-grade class raised $380 during a candy sale. They deposited the money in a savings account for 6 months. If the bank pays 5.3% simple interest per year, how much money will be in the account after 6 months?
Answer: You want to calculate the interest on $380 at 5.3% interest per year after .5 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $380.00.
r is the interest rate, 5.3% per year, or in decimal form, 5.3/100=0.053.
t is the time involved, 0.5....year(s) time periods.
So, t is 0.5....year time periods.
To find the simple interest, we multiply 380 × 0.053 × 0.5 to get your answer.
