2) If x+y=6 and xy=5 find x-y?
Answer:
x - y = ± 4Step-by-step explanation:
Given
x + y = 6 and xy = 5To find
x - ySolution
(x - y)² = (x + y)² - 4xy = 6² - 4*5 = 36 - 20 = 16 = 4²(x - y)² = 4²x - y = ± 4Solve 5.4p+13.1=−2.6p+3.5 . Check your solution.
p= __
5.4p +13.1 = −2.6p+3.5 .
5.4p + 2.6p = 3.5 -13.1
8.0p = -9.6
p = -9.6 / 8
p = -1.2

Ericka observed the total variation in the water level over 6.2 years to be −13.64 mm. She compared this to the average annual trend, which shows the water level rising 1.8 mm/year. Remember, she used 6.2 years as her time period. What is the difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
Answer:
3.96mm/year
Step-by-step explanation:
Given that :
Given that:
Observed variation in water level over 6.2 years = - 13.64mm
Average annual trend shows rise in water level at 1.8 mm / year
difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
Average Yearly observed variation :
Observed variation / number of years
-13.64mm / 6.2 years
= - 2.16 mm
Hence, observed yearly fall = - 2.16 mm
Yearly rise = 1.8mm / year
Difference :
( 1.8 mm/year) - (-2.16mm / year)
= (1.8 + 2.16) mm/year
= 3.96 mm/year
Answer:
24.8 millimeters

[tex]\displaystyle S_{27}=675[/tex]
Step-by-step explanation:
The sum of N consecutive natural numbers is given by:
[tex]\displaystyle S_N=\frac{N}{2}(F+L)[/tex]
We need to find the sum of the natural numbers between 12 to 38.
To calculate the required sum we have F=12, L=38, but we don't have the value of N.
From 12 to 38 there are 38 - 12 + 1 = 27 natural consecutive numbers, thus N=27.
Substituting in the formula:
[tex]\displaystyle S_{27}=\frac{27}{2}(12+38)[/tex]
[tex]\displaystyle S_{27}=\frac{27}{2}(50)[/tex]
[tex]\displaystyle S_{27}=27*25[/tex]

What is the slope-intercept form of the line with the point (0, 3) and a slope = -2?
O A. y = 2x + 3
O C. y = -2x + 3
D. y = -2x - 3
B. y = 2x - 3
Answer:
2nd choice OC.y=-2x+3
Step-by-step explanation:
The equation for the slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. With these two numbers both given to us, we can just plug them in and get y=-2x+3.

Step-by-step explanation:
The smaller triangle and the bigger triangle have the same angle of 60 on one side.
They also have a common point at the top, which is also called a common angle.
You only need two angles to show that two triangles are similar, because the other angle has to be the same because all angles in a triangle add up to 180.

The table shows a relationship between x-and y- values which statement describes the pattern created by the values ?
Answer:
3rd one
Step-by-step explanation:
The correct pattern created by the values is,
⇒ Each value of y is determined by adding 4 to each x - values, so the pattern is additive.
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
We have to given that;
The table shows a relationship between x-and y- values.
Now, We have;
x = 2, 4, 6, 8
y = 6, 8, 10, 12
⇒ 2 + 4 = 6
⇒ 4 + 4 = 8
⇒ 6 + 4 = 10
⇒ 8 + 4 = 12
Clearly, Each value of y is determined by adding 4 to each x - values.
Hence, The pattern is additive.

An object was dropped off the top of a building. The function f(x)=-16x^2+144f(x)=−16x 2 +144 represents the height of the object above the ground, in feet, xx seconds after being dropped. Find and interpret the given function values and determine an appropriate domain for the function.
Answer:
Step-by-step explanation:
Given the height at which an ogject dropped modelled by the function f(x)=-16x^2+144
The height of the body on the ground occurs at when f(x) = 0
0 =-16x^2+144
16x^2 = 144
x^2 = 144/16
x^2 = 9
x = 3
The ball reached the ground after 3 secs
The domain of a function is the input function that will make the function exist. Based on the function given, the function can exist on all given input value of x. Hence the domain of the function will be;
Domain =(-\infty, infty)
The domain of the function is required.
The domain of the function is the set of real numbers
[tex]x\in(-\infty,\infty)[/tex]
The function is
[tex]f(x)=-16x^2+144[/tex]
The y intercept of the function is
[tex]y=-16\times 0+144\\\Rightarrow y=144[/tex]
[tex](0,144)[/tex]
The y intercept is the maximum height here.
The x intercepts are the points where the object is on the ground.
They are
[tex]0=-16x^2+144\\\Rightarrow 16x^2=144\\\Rightarrow x=\pm\sqrt{\dfrac{144}{16}}\\\Rightarrow x=\pm3[/tex]

The revenue earned from a sporting event can be determined by the ticket price, $125 each.
Answer:
all whole numbers
all whole-number multiples of 125
Step-by-step explanation:
The domain and the range of a function is the set of input and output values of the function.
The domain is the set of all whole numbersThe range is the set of all whole numbersLet the number of tickets be x, and the revenue be y.
So, the revenue function will be:
[tex]\mathbf{y = 125x}[/tex]
The number of tickets cannot be less than 0.
So, the domain of the revenue function is:
[tex]\mathbf{Domain = [0,\infty)}[/tex]
The above means that, the domain is the set of all whole numbers
Similarly, the revenue cannot be less than 0.
So, the range of the revenue function is:
[tex]\mathbf{Range = [0,\infty)}[/tex]
The above means that, the range is also the set of all whole numbers (in multiples of 125)
