Answer:
Domain is [tex]x \ge d[/tex]
You'll check the box labeled "x", the box labeled [tex]\ge[/tex] and the box labeled "d". So you'll have 3 boxes checked.
=======================================================
Explanation:
We cannot have a negative number under the square root, and get some real number output. For example, the result of [tex]\sqrt{-4}[/tex] isn't a real number.
That means we need to have the "x-d" under the square root to be 0 or larger.
[tex]x-d \ge 0\\\\x-d+d \ge 0+d\\\\x \ge d[/tex]
The domain is [tex]x \ge d[/tex] telling us that x = d is the smallest x value we can plug in
So that's why we check off the box labeled "x", the box labeled [tex]\ge[/tex] and the box labeled "d" as shown below.
Find the mean of the following 8, 12, 16, 10, 18, 15, 22, 16, 14, 17
[tex]mean = \frac{sum \: of \: all \: observations}{number \: of \: observations} \\ = > mean = \frac{8 + 12 + 16 + 10 + 18 + 15 + 22 + 16 + 14 + 17}{10} \\ = > mean = \frac{148}{10} \\ = > mean = 14.8[/tex]

Why is it useful to have different forms of linear equations?
Linear equation is the equation of a straight line.
Forms of a linear equation
The forms of a linear equation are:
Slope intercept form - [tex]\mathbf{y = mx + b}[/tex].Point slope form - [tex]\mathbf{y - y_1 = m (x - x_1)}[/tex].Standard form - [tex]\mathbf{Ax +Bx = C}[/tex].Slope intercept form
From the slope intercept form, one can easily deduce the slope and the y-intercept of the linear equation
Point slope form
From the point-slope form, one can easily deduce the slope and the points of the graph of the linear equation
Standard form
From the standard form, the values of x and y can be easily calculated.
Hence, the usefulness of having different forms of linear equation is that they all serve different purposes, even through they represent the same graph.

Answer:
Below
Step-by-step explanation:
The domain tells you if there are any restrictions on the x's
The -5 in the function tells us that it has moved 5 units RIGHT from the original parent function. Because of this, any x coordinates have to be bigger or equal to 5!
So, the domain of this function is x >/ 5

Step-by-step explanation:
solve the following: If 7a – 4b = 3, then b =
Answer:
D (7a-3)/4
Step-by-step explanation:
7a – 4b = 3
Subtract 7a from each side
7a-7a – 4b = 3-7a
-4b = 3 -7a
Divide by -4
-4b/-4 = (3-7a)/-4
b = (7a-3)/4
Answer:
b = (7a - 3)/4
Step-by-step explanation:
7a - 4b = 3
=> -4b = 3 - 7a
=> b = (3 - 7a)/(-4)
=> b = -(3 - 7a)/4
=> b = (-3 + 7a)/4
=> b = (7a - 3)/4
Hence find the value of x that satisfies the two equations y =
5x/2-7 and y=4x/3
simultaneously.
Answer:
x=6
Step-by-step explanation:
since y=5x/2-7, and y=4x/3
so 5x/2-7=4x/3
5x/2-4x/3= 7
15x-8x/6=7
7x/6=7
x= 7*6/7= 6

There are 135 people in a sport centre. 73 people use the gym. 59 people use the swimming pool. 31 people use the track. 19 people use the gym and the pool. 9 people use the pool and the track. 16 people use the gym and the track. 4 people use all three facilities. How many people didn't use any facilities?
Answer:
24 people
Step-by-step explanation:
((The numbers are up there, so I am not going to define each variable.))
For starters, there is no overlap between the double facilities groups, except the triple facility users, so:
19 + 9 + 16 - 4 = 40 people
Since there is overlap between single and double groups, you will need to subtract, so:
Gym: 73 - 19 - 16 = 38
Pool: 59 - 19 - 9 = 31
Track: 31 - 9 - 16 = 6
Total for 1 facility: 38 + 31 + 6 - 4 = 71 people
((Minus 4 because the 4 triple facility users overlap the double facility users (problem is in layers: layer 1 minus layer 2, then minus layer 3).))
Next, add the totals:
71 + 40 = 111 people (using facilities)
135 - 111 = 24 people (who didn't use any)

Answer: q -> p
Step-by-step explanation: You've got it right! To find the converse, you switch the first and second halves of the statement and keep it positive.
Answer:
q→p
Step-by-step explanation:
The converse is a type of mathematical statement that changes the conditional statement. If the conditional statement is p→q then the converse is q→p. This is because the converse of a statement reverses any type of statement. For example, if the conditional statement is: if an angle has 90 degrees, then it is a right angle. Then, the converse would be: if an angle is a right angle, then it has 90 degrees.

It's about making up a rule that gets from one figure to the next. Here's the rule I used:
The bottom left segment is rotated 1/8 turn CW from one figure to the next.
The top middle segment is rotated 1/4 turn CW from one figure to the next.
After steps, the top middle segment will be back in the same place. The lower left segment will be in the opposite corner. This corresponds to figure C.
Phythagorean theorem help plsss rnnn
Answer:
8 m
Step-by-step explanation:
Diagonal: Hypotenuse
Let the hypotenuse (diagonal) be c, Stafford street be a, and let Silvergrove Avenue be b.
Formula: a^2 + b^2 = c^2
Lets plug them in!
6^2 + b^2 = 10^2
36 + b^2 = 100
b^2= 100 - 36
b^2 = 64
64 is the exponential value of b, meaning to lower it to its original terms, we apply the opposite of squaring. Which is finding the square root.
[tex]\sqrt{64}[/tex] = 8
Therefore Silvergrove Avenue is 8 m.
Answer:
8
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2
c (the hypotenuse, or longest leg) = 10, a or b = 6
6^2 + b^2 = 10^2
36 + b^2 = 100
b^2 = 64
b = 8

You can think of "rational" as in "ratio" which is very closely tied to fractions. Any rational number is a fraction of two integers. The denominator can never be zero.
Answer:
Rational
Step-by-step explanation:
A rational number is any integer, fraction, terminating decimal, or repeating decimal.
Decimal form: − 1.08 3
3 repeats itself, so it's rational.
