Answer:
Step-by-step explanation:
Equation of line in slope intercept form: y = mx +c
Pick any two points from the table and find the slope.
(-2 , 9) ; (-1,7)
[tex]\sf \boxed{\bf Slope= \dfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\sf = \dfrac{7-9}{-1-[-2]}\\\\=\dfrac{-2}{-1+2}\\\\=\dfrac{-2}{1}\\\\=-2[/tex]
y = -2x + c
Substitute (-2,9) in the above equation and find the y-intercept 'c'.
9 = -2*(-2) +c
9 = 4 + c
9 - 4 = c
c = 5

Janice is offered medical and dental insurance through her company. Medical insurance costs $6,740 annually and dental costs $630
annually. Jessica's company pays 70% of medical insurance and 85% of dental insurance. How much does Jessica pay each biweekly pay
period for medical and dental insurance?
Medical insurance Jessica pays biweekly is $196.58 or 197 dollars.
Dental insurance Jessica pays biweekly is $22.3125 or 22 dollars.
How to find the biweekly pay?
Janice:
Medical insurance costs $6,740 annually
Dental costs $630
Solution:
Jessica:
70% of medical insurance = 70/100*6,740
= 674 * 7
= $4,718/annum.
85% of dental insurance = 85/100 * 630
= 63 * 8.5
= $535.5/annum
Medical insurance Jessica pays per month = 4,718/12 = $393.16
Medical insurance Jessica pays biweekly = 393.16/2 = $196.58 or $197
Dental insurance Jessica pays per month = 535.5/12= $44.625
Dental insurance Jessica pays biweekly = 44.625/2 = $22.3125 or $22.

water flows at a constant rate. Kian measures 8 cups in 6 seconds. whats the constant of proportionality of cups of water to minutes
The constant of proportionality in cups of water to minute is 80 cups/min
What is the constant of proportionality in cups per minute?Here we have the proportional relation:
y = k*x
Where y is the number of cups and x the time in seconds, then:
y/x = k
Replacing the values we know:
y = 8 cups.
x = 6 seconds.
We can get the value of k, the constant of proportionality, but first, let's write the time in minutes.
x = 6 seconds
remember that 1 min = 60 sec, then:
6 sec = (6/60) min = 0.1 min
So the constant of proportionality is:
k = 8cups/0.1 min = 80 cups/min

a equals 2 over 21
Value of 'a' for the given statement the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.
As given in the question,
Given statement :
Negative a minus four sevenths equals two thirds for a
Represent the statement in equation form :
-a -(4 / 7) = ( 2 / 3 )
Solve by adding both the side ( 4 / 7 ) we get,
-a - (4 /7) + (4 /7) = (2/3) +(4/7)
⇒ -a = (2/3) + (4/7)
least common multiple of 3 and 7 is 21.
-a = ( 14 /21) + (12 /21)
⇒ -a = 26 /21
⇒ a = -26/21
Therefore, value of 'a' for the given statement the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.

The relation of the function as a product are found for the long division as: (n-2)×(6n - 16) + 0 = 6n² - 4n - 16
What is referred as the long division?Long Division is a technique for dividing large numbers that divides the problem into several steps that follow a sequence. Just like in frequent division problems, a dividend is divided by divisor, yielding the quotient and, in some cases, a remainder.Each component of a division equation has its own name.Dividend: The dividend is really the number divided during the division process.Divisor: The divisor is the number whereby the dividend is divided.Quotient: A quotient is an outcome of the division process.Remainder: We can't always divide things exactly. There could be an extra number. The leftover number is known as the remainder.The following describes the relationship between such four parts:
Divisor x Quotient + Remainder = Dividend
From the given pictures write the value of each part;
Dividend = 6n² - 4n - 16
Divisor = (n-2)
Quotient = 6n - 16
Remainder = 0
Thus, the relation becomes;
(n-2)×(6n - 16) + 0 = 6n² - 4n - 16
Thus, the relation of the function as a product are found for the long division.

today, the waves are crashing onto the beach every 4.8 seconds. the times from when a person arrives at the shoreline until a crashing wave is observed follows a uniform distribution from 0 to 4.8 seconds. round to 4 decimal places where possible.
A person will wait at least 1.8720 seconds before the wave crashes when the waves are crashing onto the beach every 4.8 second
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is given by the following formula.
[tex]P(X\leq x)[/tex] = x-a / b-a
Uniform distribution from 0 to 4.8 seconds.
This means that a=0 , b=4.8
61% of the time a person will wait at least how long before the wave crashes in?
This is the 100 - 61 = 39% percentile, which is x for which [tex]P( X\leq x)= 0.39[/tex] . So
[tex]P(X\leq x)= \frac{x-a}{b-a}[/tex]

Using the concepts of the mean and of the mean absolute deviation, the correct option is given as follows:
Last month, the amount of rain that fell each day varied less than the month before.
What is the mean absolute deviation of a data-set and what does it represent?The mean of a data-set is given by the sum of all observations divided by the cardinality of the data-set, which is the number of observations in the data-set.The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations, hence it basically is the mean of the deviations, given a degree of variability.The mean absolute deviation(MAD) represents the average by which the values differ from the mean.In this problem, we have that:
Two months ago, the measures were: Mean 9.4 cm, MAD 3.5 cm.Last month, the measures were: Mean 11.5 cm, MAD 1.6 cm.Due to the lower mean absolute deviation combined with the higher mean, the amount varied less than the month before, hence the last option is correct.

What are the rules of PERFECT SQUARE TRINOMIAL
The rules of Perfect Square Trinomial are, an expression obtained from the square of the binomial equation is a perfect square trinomial. If a trinomial is in the form [tex]ax^{2} +bx+c[/tex] is said to be a perfect square, if and only if it satisfies the condition [tex]b^{2} = 4ac[/tex].
What is Perfect Square Trinomial :Perfect square trinomials are algebraic expressions with three terms that are obtained by multiplying a binomial with the same binomial. A perfect square is a number that is obtained by multiplying a number by itself. Binomials are algebraic expressions consisting of just two terms that are either separated by a positive (+) or a negative (-) sign. Similarly, trinomials are algebraic expressions consisting of three terms. When a binomial consisting of a variable and a constant is multiplied by itself, it results in a perfect square trinomial having three terms. The terms of a perfect square trinomial are separated by either a positive or a negative sign.
A perfect square trinomial is defined as an algebraic expression that is obtained by squaring a binomial expression. It is of the form [tex]ax^{2} +bx+c[/tex]. Here a, b, and c are real numbers and a ≠ 0. For example, let us take a binomial (x+4) and multiply it to (x+4). The result obtained is [tex]x^{2} +8x+16[/tex]. A perfect square trinomial can be decomposed into two binomials and the binomials when multiplied with each other gives the perfect square trinomial.
Therefore,
An expression obtained from the square of the binomial equation is a perfect square trinomial. If a trinomial is in the form [tex]ax^{2} +bx+c[/tex] is said to be a perfect square, if and only if it satisfies the condition [tex]b^{2} = 4ac[/tex].

Therefore, CH bisects ∠GCD.
Therefore, it divide ∠GCD into two equal halves.
GC bisect ∠BGD.
Therefore, it divides ∠BGD into two equal halves.
Hence,
m∠BGC = m∠CGF
