[tex] {x}^{2} - {y}^{2} [/tex]
( where, x = 12 and y = 11 )
Answer:
here's your solution
=> we need to solve this ( x^2 -y^2)
=> it is given that x = 12 y= 11
=> now putting the value of these in question
=>. 12^2 - 11^2
=> 144 - 121
=. 23

Answer:
Step-by-step explanation:
every time x goes up 1, y goes up 4
x = 3 minus x = 2 is a delta (a change of 1)
x = 4 minus x = 3 is a delta (a change of 1)
x = 5 minus x = 4 is a delta (a change of 1)
the delta x is ALWAYS 1 for this table you can always substract x's to find the delta delta is symbolized by Δ Δx for the delta x
y = 7 minus y = 3 is a delta (a change of 4)
y = 11 minus y = 7 is a delta (a change of 4)
y = 15 minus y = 11 is a delta (a change of 4)
the delta y is ALWAYS 4 for this table you can always substract y's to find the delta delta is symbolized by Δ Δy for the delta y
the slope m = Δy / Δx m = 4 / 1 m = 4
y = mx + b when x = 0 then y = b (called the y intercept)
so how do we find the y intercept?
look at the pattern in the TABLE Δx and Δy
when x = 1 y = (3 - 4) = -1
x = 0 y =( -1 - 4) = -5
so y = 4x - 5 is a line equation for the data in this table
I believe there are other forms for linear equations
I chose the y-intercept form
use the point slope equation
(y - y1) = m(x - x1) where (x1, y1) are the coordinates of a point on
the line
when you know the slope of the line and a point on the line
as before
m = (y2 - y1) / (x2 - x1) from the table
= (7 - 3) / (3 - 2) still equals
= 4/1 = 4
pick a point on the line say x= 4 and y = 11 (4, 11)
(y - y1) = m(x - x1)
y - 11 = 4(x - 4) point slope form
solving point slope form for y
y - 11 = 4x - 16 add 11 to both sides
y = 4x - 5 back to the y-intercept form
Select all of the following that can be a counterexample for the statement below.
If x is an integer, then x + 2 > 7.
I can't see pictures, but I'm assuming you want it solved.
x+2>7.
Cancel out the 2 by subtracting 2 from both sides.
x+2>7
-2 -2
x>5
So the inequality is x>5.

Need help rewriting the equation
Given:
The equation is:
[tex]2-\dfrac{5}{6}x=\dfrac{7}{8}[/tex]
To find:
The simplified for of the given equation so that it does have fractions.
Solution:
We have,
[tex]2-\dfrac{5}{6}x=\dfrac{7}{8}[/tex]
Denominators values are 6 and 8. LCM of 6 and 8 is 24 so multiply both sides by 24.
[tex]24\left(2-\dfrac{5}{6}x\right)=24\times \dfrac{7}{8}[/tex]
[tex]24(2)-24\left(\dfrac{5}{6}x\right)=24\times \dfrac{7}{8}[/tex]
[tex]48-4\times 5x=3\times 7[/tex]
[tex]48-20x=21[/tex]
Therefore, the required equation is [tex]48-20x=21[/tex].
If 0° SOS 90° and cose
15, what is the value of sin (90° - 9)?
A: 11/15
B: 15/11
C: 15/4
D: 4/15
The value of sin (90° - 9) is 11/15, Option A is correct.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Using the trigonometric identity sin(90° - θ) = cos(θ), we have:
sin(90° - 9) = cos(9)
To evaluate cos(9) in degrees,
cos(θ) = cos(π/2 - θ)
Substituting θ = 9 degrees, we get:
cos(9) = cos(π/2 - 9°)
Using radians, π/2 - 9° = 1.4661
cos(9) = 0.9781
Therefore, sin(90° - 9) = 0.9781, which is equivalent to 11/15 when simplified.

C) $6,773.00
D) $6,776.84
Answer:
D, 6500 increased by 1.4% is 6591 plus another 1.4% which is 6683 and for the last year you add another 1.4% to get the final answer which is D 6,776.84
Answer:

Two towns tracked the attendance at their summer fairs in 2016 and 2017. The data for each town and year is shown below. Year Ogdenville North Haverbrook 2016 960 500 2017 1008 540 What was the difference between the percent increases for each town from 2016 to 2017?
Answer:
48 and 5%; 40 and 8%
Step-by-step explanation:
The computation of the difference between the percentage increase for each town from 2016 to 2017 is given below:
Year Ogdenville North Haverbrook
2016 960 500
2017 1008 540
So here the difference would be
For 2016 to 2017
= 1008 - 960
= 48
The percentage increase is
= 48 ÷ 960
= 5%
And,
= 540 - 500
= 40
And, the percentage increase is
= 40 ÷ 500
= 8%

Answer:
The larger circle has an approximate area of 314 cm²
Step-by-step explanation:
As you can see by the diagram, the white circle is twice as wide as the grey circles. That means that its radius is also twice theirs.
The grey circles have a radius of 5cm, so the larger has a radius of 10cm.
The radius of a circle is equal to πr², where r is the radius of the circle. So the larger circle's radius is:
π × 10²
≈ 3.14 × 100
= 314.
So the larger circle has an approximate area of 314 cm²

Answer:
8
Step-by-step explanation:
you want to set it up like this
8/20 and 6/2x-1
then you cross multiply
so 8(2x-1) = 16x-8
and 20*6 = 120
then you do 120= 16x-8
add 8 to both sides (you want x by it's self so to get rid of a -8 you have to add 8)
128= 16x
(divide both sides by 16)
128/16= 8
8=x

Answer:
I hope that help
Step-by-step explanation:
Any point on a two-dimensional graph can be represented by two ... For example, the point (2, 3) is two units to the right of the y-axis and three units ... and (x2, y2), you can define the exponential function that passes through these points by substituting them in the equation y = abx and solving for a and b.
Solve for x if 2(x - 2) = 26
A) x=25
B) x=8
C) x=15
D) c=30
Answer:
The answer is C x=15
Step-by-step explanation:
Simplify both sides of the equation.
2(x−2)=26
(2)(x)+(2)(−2)=26(Distribute)
2x+−4=26
2x−4=26
Add 4 to both sides.
2x−4+4=26+4
2x=30
Divide both sides by 2.
2x /2 = 30/ 2
x=15
Answer:
x= 15
