What is the best definition for combining like terms
Step-by-step explanation:
Combing like terms means that you combine the terms that are alike. So, if you have integers you would combine the integers. If you had a variable like x, you would combine everything with x. For instance, 2x+4+3+7x, to combine like terms add 4+3 and 2x+7x.

An example of something discrete is
A.a set of friends: John, Martin, and Bill
B. a set of dice landing on 3 and 4
C. both of the above
Explanation:
Choice A is discrete because it is a finite set. There aren't infinitely many names in here.
The same goes for choice B as well. We have two items in this set { (3,4), (4,3) }. The set of all possible dice rolls is also discrete as there are 6^2 = 36 different ways to roll two dice.
An example of a set that isn't discrete, and continuous, would be the set of real numbers. In this set, we can pick any two values and find the midpoint. We can do this infinitely many times. So in a way, this set is very dense and we can infinitely zoom into a particular region. We can't do the same for a set of finitely many items.
A function is called from the main function and then it calls itself five times. The depth of recursion is
Answer: five.
Step-by-step explanation: The depth of a recursion or Recursive statement can simply be explained as the maximum number of times a function calls itself until the stopping condition is met. In the scenario above, the number of times the function calls itself is five hence the depth of recursion will be five. A Recursive function or algorithm involves repetitive calling of itself( that is the Recursive function) until the condition to stop is met, hence the number of times the fuction has to call itself before the stopping condition is satisfied is called the depth of the Recursive algorithm.
A vertical shelving unit consists of five equal-sized square shelves arranged in a column to form a rectangle. The total area of all five shelves is 500 square inches. What is the length, in inches, of the shelving unit?
Answer:
50 inches
Step-by-step explanation:
Given that
5 equal sized square shelves arranged in a column.
Total area of five shelves = 500 sq inches
To find:
Length of shelving unit = ?
Solution:
First of all, let us find the area of each shelving unit.
Area of each shelving unit = Total area of five shelved divided by 5
Area of each shelving unit = 500 [tex]\div[/tex] 5 = 100 sq units.
Each shelving unit is of square shape and area of a square is given as:
Area = [tex]Side^2[/tex]
100 = [tex]Side^2[/tex]
So, side of shelve = 10 inches
Now, there are 5 squares in the shelving unit.
So, length of shelving unit = [tex]10 \times 5 = \bold{50 \ inches}[/tex]

A square has a side length 15.8cm.If 3 such squares are linked side to side in a straight line, what is the perimeter of the whole shape?
Answer:
126.4 cm
Step-by-step explanation:
1. 15.8 * 3 = 47.4 (This is the length)
2. Find half of the rectangle
47.4 + 15.8 (width) = 63.2
3. Find the whole perimeter
63.2 * 2 = 126.4
Answer:
126.4
Step-by-step explanation:
If you put three squares that are all 15.8cm together, you get a rectangle that is 47.4cm by 15.8cm. To get 47.4, you multiply 15.8 x 3 because it's three 15.8 squares together. Then to find the perimeter of the rectangle, you add all the sides together to get the answer 126.4.

Solve for the exterior angle in the image below?
Answer:
x = 7
Exterior angle = 139°
Step-by-step explanation:
[tex] (15x + 34) [/tex] is an exterior angle to the ∆ given.
29° and [tex] (12x + 26) [/tex] are two opposite interior angles of the ∆.
According to the external angle theorem, [tex] (15x + 34) = 29 + (12x + 26) [/tex]
Solve for x using this expression
[tex] 15x + 34 = 29 + 12x + 26 [/tex]
[tex] 15x + 34 = 29 + 26 + 12x [/tex]
[tex] 15x + 34 = 55 + 12x [/tex]
[tex] 15x + 34 - 12x = 55 + 12x - 12x [/tex]
[tex] 15x - 12x + 34 = 55 [/tex]
[tex] 3x + 34 - 34 = 55 - 34 [/tex]
[tex] 3x = 21 [/tex]
[tex] \frac{3x}{3} = \frac{21}{3} [/tex]
[tex] x = 7 [/tex]
Exterior angle = [tex] (15x + 34) [/tex]
Plug in the value of x
[tex] 15(7) + 34 = 105 + 34 = 139 [/tex]
Exterior angle = 139°

The width of a rectangular parking lot is 20 meters less than the length. The perimeter is 200
meters. Find the length and the width.
Answer:
Length=60 meters, width=40 meters.
Step-by-step explanation:
If the perimeter of the rectangular is 200 that means length*width=100. So we take 50 and add 10 and subtract 10. So the width is 40 and the length is 60

Algebraically determine each of the following for the function y=16 - 4x(squared). A) the x and y intercepts if any. B) the symmetry type (x axis, y axis, origin, or neither.)
Answer:
A) x intercept: (2, 0) , (-2, 0)
y intercept: (0, 16)
B) symmetric about y axis
Step-by-step explanation:
Given the function:
[tex]y=16-4x^{2}[/tex]
To find:
Algebraically, A) find the x and y intercepts and B) the symmetry type.
Solution:
A) x intercept, let us put y = 0
[tex]y=16-4x^{2}[/tex]
[tex]0=16-4x^{2}\\\Rightarrow 4x^2=16\\\Rightarrow x^2=4\\\Rightarrow x =+2, -2[/tex]
x intercept: (2, 0) , (-2, 0)
For y intercept, put x = 0
[tex]y=16-4x^{2}[/tex]
y = 16 - 0 =16
y intercept: (0, 16)
B) If the quadratic equation is given as: [tex]y=ax^2+bx+c[/tex],
the axis of symmetry is a vertical line [tex]x=-\frac{b}{2a }[/tex]
Here, c = 16
b = 0 and
a = -4
So, Axis of symmetry is:
[tex]x=-\dfrac{0}{2\times (-4)} = 0[/tex]
which is the equation of y axis.
So, given equation is symmetric about y axis.

For any positive integer n, the sum of the first n positive integers equals n ( n 1 ) 2 . What is the sum of all the even integers between 99 and 301
Answer:
The sum of all the even integers between 99 and 301 is 20200
Step-by-step explanation:
For the sum of all the even integers between 99 and 301, this can be calculated using the formula for Sum of n terms in an Arithmetic Progression (AP)
Sum of n terms in an AP [tex]S_{n}[/tex]= [tex]\frac{n }{2}[ 2a + (n - 1)d][/tex]
Where [tex]n[/tex] is the number of terms
[tex]a[/tex] is the first term
and [tex]d[/tex] is the common difference
The AP for the sum of all the even integers between 99 and 301 will look like
100 + 102 + 104 + ... + 300
[tex]a[/tex] = 100
[tex]d[/tex] can be calculated by taking the difference of the first two terms or any two consecutive terms of the AP
Hence, [tex]d[/tex] = 102 - 100 = 2
[tex]n[/tex] can be determined from the formula used to calculate the Last term of an AP
[tex]l = a + (n - 1)d[/tex]
Where [tex]l[/tex] is the last term
In the AP, the last term, [tex]l[/tex] = 300
Then
[tex]300 = 100 + (n - 1)2\\300 - 100 = (n - 1)2\\200 = (n - 1) 2\\(n - 1) = 200 / 2\\n - 1 = 100\\n = 100 + 1\\n = 101[/tex]
Hence, there are 101 terms in the AP
Now, to determine the sum
[tex]S_{n}[/tex]= [tex]\frac{n }{2}[ 2a + (n - 1)d][/tex]
[tex]S_{n} =\frac{101}{2}[ 2(100) + (101 - 1)2]\\ S_{n}=\frac{101}{2}[ 200 + (100)2]\\ S_{n}=\frac{101}{2}[ 200 + 200]\\S_{n}=\frac{101}{2}[ 400]\\S_{n} = 20200[/tex]
Hence, the sum of all the even integers between 99 and 301 is 20200

Step-by-step explanation:
explain: Let's solve for x. labc=x−32 Step 1: Flip the equation. x−32=abcl Step 2: Add 32 to both sides. x−32+32=abcl+32 x=abcl+32 Answer: x=abcl+32
Answer:
x=abcl+32
Step-by-step explanation:
We need to solve for x for the below expression :
labc=x−32
Fisrt let's flip the question.
x-32=abcl
Add 32 on both the sides
x-32+32=abcl+32
We know that -32+32 = 0
x = abcl+32
So, the value of x is abcl+32.
You are playing basketball with your friends. The height (in feet) of the ball above the ground t seconds after a shot is released from your hand is modeled by the function f(t)= -16t^2 + 32t + 5.2. What is the value of t when the ball is released from your hand ?
Answer:
Value of (t) = 0
Step-by-step explanation:
According to the scenario no time has passed.
t = 0
Given:
f(t)= -16t² + 32t + 5.2
When t = 0
So.

3x + 2x - 10 = 25
→ Add the 'x's together
5x - 10 = 25
→ Add 10 to both sides to isolate 5x
5x = 35
→ Divide both sides by 5 to isolate x
x = 7
What is the image of the point (4,5) after a rotation of 90° counterclockwise about
the origin?
Answer:
A counterclockwise rotation of 270º about the origin is equivalent to a clockwise rotation of 90º about the origin. Given a point (4, 5), the x-value, i.e. 4 and the y-value, i.e. 5 are positive, hence the point is in the 1st quadrant of the xy-plane.

How do I find the slope to this equation ?
2х-Зу = 12
Answer:
slope = [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x - 3y = 12 ( subtract 2x from both sides )
- 3y = - 2x + 12 ( divide all terms by - 3 )
y = [tex]\frac{2}{3}[/tex] x - 4 ← in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Answer:
2/3
Step-by-step explanation:
Slope of the equation is determined as per slope-intercept form:
y = mx +bBring the given equation to mentioned form:
2x - 3y = 12 ⇒ make y the subject3y = 2x - 12 ⇒ divide all terms by 3y = 2/3x - 4 ⇒ this is the slope-intercept formSince m = 2/3, it is the slope of the given equation
