The equation that is parallel and perpendicular are y + 4 = 7/5(x-35) and y+4 = -5/7(x - 35) respectively.
Equation of a lineA line is defined as the shortest distance between two points. The formula for finding the equation of a line in point slope form is:
y - y₁ = m(x-x₁) (Parallel lines)
y - y₁ = -1/m(x-x₁) (Perpendicular lines)
Given the following parameters;
Point = (35, -4)
Given the equation 7x-5y = 0
5y = 7x
y = 7/5x
Slope = 7/5
Substitute the slope and point into the equation
y + 4 = 7/5(x-35) (Parallel lines)
y +4 = -1/(7/5)(x-35) (Perpendicular lines)
y+4 = -5/7(x - 35)(Perpendicular lines)

Debra is 7 years younger than Pamela. In 6 years, Pamela will be twice as old as Debra. How old is Pamela now?
Pamela is 1 year old now.
How to solve problems on ages ?
If the present age of a person be X, thenAge after n years = X +n
Age n years ago = X - n
n times the present age = nX
If ages in the numerical are mentioned in the ratio A : B, then A : B will be AX and BX.
If the sum of ages is X and Y and the ratio of their ages is p : q respectively, then you can determine the age of Y by using the formula shown below:Age of Y = Ratio of Y / Sum of ratios x sum of ages
Age of Y = q/ (p +q) x A
In the given statement is:
Debra is 7 years younger than Pamela. In 6 years, Pamela will be twice as old as Debra.
To find the how old is Pamela now.
Now, Based on the given conditions,
Formulate:
Let x be the Pamela's age

Exactly 120 years ago, students planted a tree in front of their school. Since then, the tree has grown 33 meters taller and the distance around the trunk has increased by 3 meters. Use pencil and paper. Describe how you can use this information to find at least two different unit rates. Then find these unit rates.
Answer: Rate of tree's height per year = 0.275 m per year.
Rate of tree's trunk per year = 0.025 m per year.
Step-by-step explanation:
Given data,
Exactly 120 years ago, students planted a tree in front of their school
Since then, the tree has grown 33 meters taller
The distance around the trunk has increased by 3 meters.
Define Unit rate :
A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
So, we can write,
There are 2 various unit rates in this:
The increase of the tree's height per year
The increase of the tree's trunk per year
Let us assume,
The increase of the tree's height per year = x
The increase of the tree's trunk per year = y
we can solve it :
Rate of tree's height per year x = 33m / 120 years
x = 0.275 m per year.
Rate of tree's trunk per year y = 3m / 120 years
y = 0.025 m per year.
Therefore,
Rate of tree's height per year = 0.275 m per year.
Rate of tree's trunk per year = 0.025 m per year.

Given, the teacher has 48 juice boxes and
64 candies for a Halloween party.
Each student will be given an equal number of juice boxes or sweets, and each one must be consumed.
how many (greater) number of students can attend the party = ?
In order to determine the greatest students we need to calculate the greatest common divisor of the numbers.
To calculate the greatest common divisor, we need to find out the prime factors of each number.
Therefore, by the method of prime factorization.
Prime factors of 48 = 2 × 2 × 2 × 2 × 3
Prime factors of 64 = 2 × 2 × 2 × 2 × 2 × 2.
Now, HCF of (48,64) = 2 × 2 × 2 × 2 = 16
Therefore we get the gcd as 16.
Hence the greatest number of students who can attend the party is 16.

Nadia says the hypotenuse of this right triangle has a length of 73 because the Pythagorean theorem states that (28 + 45) squared = 73 squared.
3 squares are positioned to form a right triangle. The small square is labeled 28, medium square is 45, and large square is not labeled.
Which best describes Nadia’s solution?
She is correct because she applied the Pythagorean theorem properly and her arithmetic is accurate.
She is incorrect because she should have used 45 as the length of the hypotenuse.
She is incorrect because she should have squared each leg length and then found the sum.
She is correct because the hypotenuse is the longest side of the triangle.
Nadia's solution is incorrect because she should have squared each leg length and then found the sum.
What is the Pythagorean theorem?A right angled triangle is a three-sided polygon. The three sides are the length, base and the hypotenuse. The hypotenuse is the longest side of the triangle. The sum of angles in a right angled triangle is 180 degree.
The Pythagorean theorem can be used to determine the length of the hypotenuse given the lengths of the other sides of the triangle. According to this theorem, the sum of the square of the two sides is equal to the length of the hypotenuse.
The Pythagoras theorem: a² + b² = c²
where:
a = lengthb = basec = hypotenuse28² + 45²

Write an equation for a line perpendicular to y = 3x + 2 and passing through the point (9,1)
Step-by-step explanation:
the slope of a line is always the factor of x, and it is defined as ratio (y coordinate change / x coordinate change) when going from one point to another on the line.
in that sense it is y/x.
the perpendicular slope turns that ratio upside-down and flips the overall sign.
so, in our case, the original slope is 3 = 3/1.
the perpendicular slope is then -1/3.
so, now, we have the slope and a point, and we can start with the point-slope form of the line equation :
y - y1 = a(x - x1)
"a" being the slope, (x1, y1) being the point.
y - 1 = -1/3 × (x - 9) = -x/3 + 3
y = -x/3 + 4
and that is the usual slope-intercept form
y = ax + b
"a" is again the slope, "b" is the y-intercept (the y value when x = 0).
An analysis of the amount of fiber (in grams) and the potassium content(in milligrams) in servings of 77 breakfast cereals produced the regression model
Ths meaning of the slope based on the information is that the model predicts that cereals will have approximately 26 more milligrams of potassium for every additional gram of fiber.
How to illustrate the information?It should be noted that the analysis of the amount of fiber (in grams) and the potassium content(in milligrams) in servings of 77 breakfast cereals produced the regression model.
The model used was:
Potassium = 35 + 26 Fiber
Therefore, the meaning of the slope based on the information is that the model predicts that cereals will have approximately 26 more milligrams of potassium for every additional gram of fiber.

Find the area of a parallelogram with a base of 9 ft a height of 4 ft.
Estimate the probability that an NBA player who makes 80% of his free throws makes 2 of his next 3 free throws.
The probability that an NBA player who makes 80% of his free throws makes 2 of his next 3 free throws is 0.384
What is probability?Probability is the extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases.
Now it is given that,
The proportion of free throws the player makes, p = 80% = 0.8
The number of throws, n = 3
The throws the player makes, r = 2
Since the probability is given as,
P(r) = nCr x p^r x (1 - p)^(n-r)
So, the probability that an NBA player makes 2 of his next 3 free throws
Putting the values we get,
P(2) = ³C₂ x (0.8)^2 x (1 - 0.8)^(3-2)
Solving we get,
P(2) = 3 x 0.64 x (0.2)^(1)
Thus we get,
P(2) = 3 x 0.64 x 0.2
Multiplying we get,
P(2) = 0.384
this is the required probability that an NBA player makes 2 of his next 3 free throws.
Thus, the probability that an NBA player who makes 80% of his free throws makes 2 of his next 3 free throws is 0.384

Which equation and number line show that a number and its opposite are additive inverses?
An equation and number line which shows that a number and its opposite are additive inverses is: 2 + (-2) = 0 in graph B.
What is a number line?A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numerical values that are placed at equal intervals along its length.
What is an additive inverse?An additive inverse can be defined as a number (n) which when added to another number (a) makes it equal to zero (0). This ultimately implies that, an additive inverse is the opposite of another number (a).
Mathematically, an additive inverse can be represented by the following expressions:
a + n = 0
a = -n
In this context, we can reasonably infer and logically deduce that an equation and number line which shows that a number and its opposite are additive inverses is 2 + (-2) = 0 in graph B (see attachment).
