Answer:
If the table is:
x=2 y=22
x=7 y=77
x=9 y=99
you can see that 22/2=11 same with 7/77 and 9/99
r=11
Step-by-step explanation:
pretty simple but i probably explained it horribly
The constant of proportionality (r) is 11 for the given variables in the table.
What is the constant of proportionality?The constant of proportionality is the constant value of the ratio of two proportional values. A proportionality relation exists between two changing quantities when either their ratio or product gives a constant.
The table is given in the question consists as:
The value of variable x = 2 when variable y = 22
The value of variable x = 7 when variable y = 77
The value of variable x = 9 when variable y = 99
We have to determine the constant of proportionality (r)
the constant of proportionality (r) = y / x
Substitute the values in the above equation,
the constant of proportionality (r) = 22/2 = 7/77 = 9/99 = 11
the constant of proportionality (r) =11
Thus, the constant of proportionality (r) is 11 for the given variables in the table.

.Solve for x in the equation below:
x1/2- 4 = 8
Answer:
x = 144
Step-by-step explanation:
[tex] x^\frac{1}{2} - 4 = 8 [/tex]
Add 4 to both sides.
[tex] x^\frac{1}{2} = 12 [/tex]
Square both sides since x^(1/2) is the same as sqrt(x).
[tex] (x^\frac{1}{2})^2 = (12)^2 [/tex]
[tex] x^{\frac{1}{2} \times 2} = 144 [/tex]
[tex] x^1 = 144 [/tex]
[tex] x = 144 [/tex]
A farmer wants to fence off part of a rectangular field to create an area that is 22,500 square feet. He then wants to divide that area in half by creating a fence parallel to one side of the rectangle. Find the dimensions of the area that will minimize the amount of fencing he needs.
Answer:
90 x 125
Step-by-step explanation:
22500÷2 = 11250
factors of 11250 = {1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 125, 150, 225, 250, 375, 450, 625, 750, 1125, 1250, 1875, 2250, 3750, 5625, 11250} (this took me long to type and calculate lol)
well we want the factors as close as possible to minimize the perimeter. In this case, it is 90 and 125. therefore the dimenstions are 90 x 125
expand and simplify (x+1)(x+7)
Answer:
Factored?
x^2 + 8x +7
Step-by-step explanation:
x times x = x^2, with 7 times x = 7x and x times 1 = 1x. Add those two common terms together to get 8x. Then lastly 7 times 1 =7 so add that.
Simplify form of (x + 1)(x + 7) is equals to x² +8x +7.
What is simplification?
"Simplification in mathematics means to write the given expression in such a way that it is easy to understand."
According to the question,
Simplify the given equation by opening the brackets we get,
(x + 1)(x + 7)
= x² + 1x +7x +7
= x² + 8x + 7
Hence, simplify form of (x + 1)(x + 7) is equals to x² +8x +7.

Laura is graphing an absolute-value function in the form
f(x) = a|x - h| +k. She determines that the domain
is (-00,00) and that the minimum value is y=-3.
What might be the equation of this function?
A. f(x) = \x + 3) + 3
B.f(x) = -3\x+31 - 3
C.f(x) = (x – 31 - 3
D.f(x) = 3|x – 3] + 3
Answer:
The equation of the function is;
y = |x-3| -3
Step-by-step explanation:
Here, we want to give the absolute-value function
For the minimum value to be -3, it means that k is negative
since the domain is the set of all real numbers, then we do not have any undefined value for the range y
So, the equation is ;
y = |x-3| - 3

OA) xs O and x > 3
OB) xs O or x3
OC) 0
OD) x<0 or x> 3
Answer:
D) x<0 or x>3
Step-by-step explanation:
x(x-3)>0
either x>0 and x-3>0 .... positive-positive=positive so x>3
or x<0 and x-3<0 ..... negative-negative=positive so x<0
if x=0 then x(x-3)=0
The solution to the inequality is x < 0 or x > 3
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To solve the inequality x(x - 3) > 0, we can use a sign chart.
First, we can find the critical points of the inequality, which are the values of x that make the expression x(x - 3) equal to zero. These values are x = 0 and x = 3.
Then, we can create a sign chart with these critical points and test intervals between them to determine the sign of the expression x(x - 3) in each interval.
Interval Test Value x(x - 3)
x < 0 -1 Positive
0 < x < 3 1 Negative
x > 3 4 Positive
From the sign chart, we see that x(x - 3) is positive when x < 0 and when x > 3, and negative when 0 < x < 3.
Hence , the solution to the inequality x(x - 3) > 0 is x < 0 or x > 3

What is the ratio of the number of beaks to the number of legs the chickens and the sheep have on this farm?
Number of Chickens Number of Sheep
8 14
1 to 9
because 1 chicken has 1 beak so the ratio of beaks is 8
1 sheep has 4 legs while 1 chicken has 2 legs

Suppose the newspaper states that the probability of rain today is 50%. What is the complement of the event "rain today"?
Answer:
50%
Step-by-step explanation:
Given that :
Let Probability of rain today = P(rain today) = 50% = 0.5
The complement of an event A denoted as A' means the opposite of event A is obtained by subtracting event a from 1.
P(rain today) = 0.5
The complement of P(rain today) ; means the probability that it will NOT rain today;
Hence, P(raintoday') = 1 - 0.5 = 0.5 = 50%
