x=3/5
Answer:
x = 0.6
Step-by-step explanation:
x/3 = 2/10
x/3 = 0.2
Multiply both sides by 3
x = 0.6
How would you factor a^3 - b^3? Please leave detailed instructions. Thanks so much!
a³ - b³ = (a - b) (a² + ab + b²)
You can see why this works if you expand the right side as
a (a² + ab + b²) - b (a² + ab + b²)
(a³ + a²b + ab²) - (a²b + ab² + b³)
Both the a²b and ab² terms cancel, leaving you with a³ - b³.

Answer:
x= 2.2
Step-by-step explanation:
10/11 = 2/x
cross multiply to get
10x=22
x=2.2
Answer:
x = 2.2 (Verified Answer) ✅Step-by-step explanation:
We need to set up a proportion where the triangle with side x is proportional to the triangle with a side measure of 2.
So, 10/2 = 11/x
We cross multiply to get 10x = 22
Dividing gives us x = 2.2
We can check our answer by substituting our answer in for x.
10/2 = 11/2.2
22 = 22 ✅

Step-by-step explanation:
Write the equation of a quadratic with x-intercept at 10 and 6 and passing through the point (11,8)
The quadratic equation with x-intercept at 10 and 6 and passing through the point (11,8) is 5y = 8(x²-16x +60).
As given in question,
Given x-intercept at 10 and 6
The quadratic equation with x-intercept is
y = k(x-10)(x-6) ___(1)
Passing through the point (11,8)
8= k(11-10)(11-6)
⇒8=5k
⇒k=8/5
Substitute the value k in (1) to get quadratic equation with x-intercept :
y = (8/5)(x-10)(x-6)
⇒5y = 8(x²-16x+60)
Therefore, the quadratic equation with x-intercept at 10 and 6 and passing through the point (11,8) is 5y = 8(x²-16x +60).

The area of a rectangle is 24 square centimeters and its side lengths are x centimeters and x+ 2 centimeters,
a. Find the side lengths of the rectangle. Justify your answer.
b. Find the perimeter of the rectangle.
Step-by-step explanation:
area of rectangle= x ( x +2 ) = 24
X2 + 2X = 24
X 2 +2X _24 = 0
(X +6 ) ( X _4 ) = 0
X= 4
X= - 6.......refused
side length of rectangle is 4 , 6
perimeter= 2( 4+6) = 20 Cm
The side lengths are 4cm , 6cm and perimeter of rectangle is 20cm.
What is perimeter of rectangle?The perimeter of a rectangle is the sum of its four sides. Hence,
Perimeter of Rectangle = 2 (Length + Width) units.
What is area of rectangle?The area of the space occupied within the perimeter of a rectangle is called the area of a rectangle. It is calculated by finding the product of the length and breadth of the rectangle.
Area of rectangle = Length * Breath
According to the question
Area of a rectangle = 24 square centimeters
Side length = x+ 2
Side Breath = x
Now,
a> using Formula of Area of rectangle
Area of rectangle = Length * Breath
substituting the value
24 = x * (x+2 )
24 = [tex]x^{2} +2x[/tex]
[tex]x^{2} +2x[/tex] - 24 = 0
[tex]x^{2} + (6-4)x -24 =0[/tex]
(x +6 ) (x-4) = 0
x = -6 , +4
side cannot be negative
Therefore
Breath of rectangle (x) = 4 cm
Length of rectangle (x+2) = 6 cm
b> Perimeter of the rectangle = 2 (Length + Breath) units.
substituting the value
Perimeter of the rectangle = 2 ( 4 + 6 )
= 20 cm
Hence, The side lengths are 4cm , 6cm and perimeter of rectangle is 20cm.

What is the equation of the line that passes through the points (5, 3) and (-3,-1)?
Answer:
y=1/2x+1/2
m=1/2
Step-by-step explanation:
You want to find the equation for a line that passes through the two points:
(5,3) and (-3,-1).
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
First, let's find what m is, the slope of the line...
The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.
For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:
So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (5,3), point #1, so the x and y numbers given will be called x1 and y1. Or, x1=5 and y1=3.
Also, let's call the second point you gave, (-3,-1), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=-3 and y2=-1.
Now, just plug the numbers into the formula for m above, like this:
m=
-1 - 3 over
-3 - 5
or...
m=
-4 over
-8
or...
m=1/2
So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:
y=1/2x+b
Now, what about b, the y-intercept?
To find b, think about what your (x,y) points mean:
(5,3). When x of the line is 5, y of the line must be 3.
(-3,-1). When x of the line is -3, y of the line must be -1.
Because you said the line passes through each one of these two points, right?
Now, look at our line's equation so far: y=1/2x+b. b is what we want, the 1/2 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (5,3) and (-3,-1).
So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!.
You can use either (x,y) point you want..the answer will be the same:
(5,3). y=mx+b or 3=1/2 × 5+b, or solving for b: b=3-(1/2)(5). b=1/2.
(-3,-1). y=mx+b or -1=1/2 × -3+b, or solving for b: b=-1-(1/2)(-3). b=1/2.
See! In both cases we got the same value for b. And this completes our problem.
The equation of the line that passes through the points
(5,3) and (-3,-1)
is
y=1/2x+1/2

What is the first term of an AP whose common difference is 2 and 31st term begin -88
Answer:
a₁ = - 148
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given d = 2 and a₃₁ = - 88 , then
a₁ + (30 × 2) = - 88
a₁ + 60 = - 88 ( subtract 60 from both sides )
a₁ = - 148
a₁ = - 148
Step-by-step explanation:
The n th term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given d = 2 and a₃₁ = - 88 , then
a₁ + (30 × 2) = - 88
a₁ + 60 = - 88 ( subtract 60 from both sides )
a₁ = - 148

function f gives the distance of a dog from a post, in feet, as a function of time in seconds, since its owner left. Find the value of f(20) and of f(140)
The value of f(20) is 3 feet , and the value of f(140) is 3.5 feet .
In the question ,
the graph represents a function which gives the distance of a dog from a post (in feet ) ,
to find, f(20) which means the distance of the dog from the post after 20sec .
As we can see from the graph that at t=20 sec the distance from post (in feet ) is 3feet .
which means f(20) = 3feet .
Also from the graph we see that at t=140 sec the distance from post (in feet ) is 3.5 feet .
which means f(140) = 3.5 feet .
Therefore , the value of f(20) is 3 feet , and the value of f(140) is 3.5 feet .
