Find the unknown coordinate so the line through the
points has the given slope
Answer:
#1 (0,-4)
#2 (5,0)
#3 (3,1)
Step-by-step explanation:
#1. (-3, 2) (0, y) slope = -2
slope = rise/run therefore slope = -2/1 or down 2 and over 1
so from -3 to 0 you are going over 3 units (or 3 times) Therefore to find y at x=0, you have to move three steps, or 3 times -2 = -6 so 2-6 = -4
so y intercept (b) = -4 0r (0,-4)
#2 (-7,-4) (x,0) slope (m) = 1/3 -7+12=5 x=5
#3 (4,-3) (x, 1) slope (m) = -4 (4/-1) Moving one unit in slope means
-3=4=1 for Y and 4-1=3 for X therefore the point is (3, 1)

if x-y = 8 and xy=5 , find x^2 + y^2
Answer:
x² + y² = 74
Step-by-step explanation:
given
(x - y) = 8 ( square both sides )
(x - y)² = 8² ← expand left side using FOIL
x² - 2xy + y² = 64 ← substitute xy = 5
x² - 2(5) + y² = 64
x² - 10 + y² = 64 ( add 10 to both sides )
x² + y² = 74
Question 2: Benjamin rolls an ordinary six-sided dice and flips a coin. List all the possible outcomes.
Answer:
Step-by-step explanation:
The slope of the tangent line to the curve y= 3/x
at the point 5, 3/5 is-
The equation of this tangent line can be written in the form y = mx + b
where:
m is:
b is:
The tangent line at that point is:
y = (-3/25)*x + 6/5
so m = -3/25, and b = 6/5
How to find the slope of the tangent line?To find the slope at that point, we need to evaluate the derivative at that point.
y = 3/x
The derivative is:
y' = -3/x²
When x = 5, we have:
y' = -3/5² = -3/25
So that is the slope, m.
Now let's find the line.
The line must pass trhough the point (5, 3/5), then:
3/5 = (-3/25)*5 + b
3/5 = -3/5 + b
3/5 + 3/5 = b
6/5 = b
The equation of the line is:
y = (-3/25)*x + 6/5

Therefore, the probability that less than 2 Americans in a random sample of 300 will be diagnosed with the rare virus in a year is 0.9703 or about 97.03%.
What is probability?Probability is a branch of mathematics that deals with the study of uncertainty and randomness. It is used to quantify the likelihood of an event or a set of events occurring. Probability can be expressed as a number between 0 and 1, with 0 indicating that the event is impossible, and 1 indicating that the event is certain.
Here,
1a) Let X be the number of Americans in a sample of 100 who will be diagnosed with lung cancer in their lifetime. Then X follows a binomial distribution with n = 100 and p = 0.0625. We want to find P(X < 0.05*100) = P(X < 5). Using the binomial probability formula or a binomial calculator, we get:
P(X < 5) = 0.0066
Therefore, the probability that less than 5% of a random sample of 100 Americans will be diagnosed with lung cancer is 0.0066 or about 0.66%.
1b) If a random sample of 100 Americans who smoke cigarettes results in 20 or more being diagnosed with lung cancer, it would be considered abnormal or rare. This may suggest a higher risk of developing lung cancer among smokers.
2a) Let Y be the number of Americans in a sample of 300 who will be diagnosed with the rare virus in a year. Then Y follows a binomial distribution with n = 300 and p = 0.005. We want to find P(Y < 2). Using the binomial probability formula or a binomial calculator, we get:

Instead of using the values {1,2,3,4,5,6) on dice, suppose a pair of dice have the following: {1,2,2,3,3,4} on one die and {1,3,4,5,6,8} on the other. Find the probability of rolling a sum of 6 with these dice. Be sure to reduce.
Answer:
the probability of rolling a sum of 6 with these dice is 1/6.
Step-by-step explanation:
To find the probability of rolling a sum of 6 with the given pair of dice, we can first list all possible pairs of outcomes that add up to 6:
(2,4)
(3,3)
(4,2)
For each of these pairs, we need to find the probability of rolling each number on its respective die and then multiply those probabilities together. The probability of rolling a particular number on one die is the number of times that number appears on that die divided by the total number of outcomes on that die.
For the first pair (2,4), the probability is:
(2 appears twice on one die out of six possible outcomes) × (4 appears once on the other die out of six possible outcomes) = (2/6) × (1/6) = 1/18
For the second pair (3,3), the probability is:
(3 appears twice on one die out of six possible outcomes) × (3 appears twice on the other die out of six possible outcomes) = (2/6) × (2/6) = 4/36
For the third pair (4,2), the probability is:
(4 appears twice on one die out of six possible outcomes) × (2 appears twice on the other die out of six possible outcomes) = (2/6) × (2/6) = 4/36
The total probability of rolling a sum of 6 is the sum of the probabilities of each possible pair:
1/18 + 4/36 + 4/36 = 1/6
Therefore, the probability of rolling a sum of 6 with these dice is 1/6.

Lisa is framing a rectangular painting length more than twice the widthShe uses 30 inches of framing material. What the length of the paintingWrite equation and solve.
A.3w+3=30;21
b.3w+3=30;9
C.6w+6=30;11
D.6w + 6 = 30 = 4
Answer:
6w = 30
Step-by-step explanation:
We should know that the 30 inches of framing material were used to frame the four sides of the rectangle.
The perimeter of the rectangle is what we should be considering, whenever we are dealing with frames.
This is 2 X (length + width)
From the questions, we can get the dimensions of the rectangle using clues from the various statements made.
From the statement"a rectangular painting length more than twice the width" we can see that the
L = 2w ------------------------- equation 1
substituting this value into the formula for the perimeter of the rectangle we have
30 = 2(2w + w)
30 = 6w
w= 5
from equation 1
L =2 X (5) = 10
Hence, we can set up the equation
6w = 30
However, the closest option to what we have is option D
6w + 6 = 30 - 4
complete question:
Lisa is framing a rectangular painting. The length is three more than twice the width. She uses 30 inches of framing material. What is the length of the printing? Write an equation and solve
Answer:
D.6w + 6 = 30 = 4
Step-by-step explanation:
perimeter = 30 inches
width = w
length = 2w + 3
perimeter of a rectangle = 2l + 2w
where
w = width
l = length
Therefore,
perimeter of a rectangle = 2(2w + 3) + 2w
perimeter of the rectangle = 4w + 6 + 2w
perimeter = 6w + 6
recall
perimeter = 30 inches
6w + 6 = 30
6w = 24
divide both sides by 6
w = 24/6
w = 4

We know that the sum of the angles of a triangle is 180
Assume that the angles are equal

PLS HELP! I REALLY REALLY NEED HELP REALLY REALLY BAD!
Answer:
X=115°
Step-by-step explanation:
If you extend the line on the left up to the top, it forms a triangle. The three interior angles of that triangle are 50, 180-x, and 180-x.
50+180-x+180-x=180
410-2x=180
410-180=2x
230=2x
x=115°
Another way to look at it: Since two of the angles in the triangle are the same, they must total 130. (180-50=130)
130 ÷2 equals 65. If those angles are 65, x=180-65=115°

If mZA = (4x - 2)° and mZB= (6x-20), what is the value of x?
To find the value of x, we can set the two angle measures equal to each other and solve for x.
Given:
mZA = (4x - 2)°
mZB = (6x - 20)°
Setting them equal to each other:
4x - 2 = 6x - 20
Now, we can solve for x:
4x - 6x = -20 + 2
-2x = -18
Dividing both sides by -2:
x = -18 / -2
x = 9
Therefore, the value of x is 9.
Answer:
The answer is 9.
Step-by-step explanation:
We need to use the fact that the sum of the angles in a triangle is 180 degrees. Let A, B, and C be the three angles in the triangle. Then we have:
mZA + mZB + mZC = 180°
Substituting the given values, we get:
(4x - 2)° + (6x - 20)° + mZC = 180°
Simplifying the left side, we get:
10x - 22 + mZC = 180°
Next, we use the fact that angles opposite congruent sides of a triangle are congruent. Since we know that segment AC and segment BC are congruent, we have:
mZA = mZB
Substituting the given values and simplifying, we get
4x - 2 = 6x - 20
Solving for x, we get:
x = 9
Therefore, the value of x is 9.
