Write an inequality for the given graph! Please help!
Answer:
y < 1/2 x - 3
Step-by-step explanation:
The line crosses the y-axis (up and down numbered axis) at -3. That's the - 3 in the equation. If you look very carefully, closely, you can see that the line, from there, goes UP1 and OVER2 to get to the next point (and the next point and the next point) This is the slope, it goes in front of the x, here it is UP1 and OVER2 and is written 1/2.
The line is dashed so the symbol is < "less than" WITHOUT the line mark underneath it; also because the shading is BELOW the dashed line we use < "less than" and not > "greater than"

find the 7th term
3, 1,1/3
The sequence 3, 1,1/3 is a geometric sequence
The 7th term of the sequence is 1/243
How to determine the 7th term?The sequence is given as:
3, 1,1/3
The above sequence is a geometric sequence with the following parameters:
First term, a= 3Common ratio, r = 1/3The nth term is then calculated as:
Tn = ar^(n-1)
So, the 7th term is:
T7 = ar^6
Substitute known values
T7 = 3 * (1/3)^6
This gives
T7 = 1/3^5
Evaluate
T7 = 1/243
Hence, the 7th term of the sequence is 1/243

9000 ways to create 4-digit passwords using digits from 0 to 9 that the first character can't be 0, but not using the digit 0 as the first character.
We have to see how many different 4-digit passwords we can create by using digits from 0 to 9, such that the first character can't be 0.
What is the combination?Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.
Here we have 4 selections.
Now let's find the number of options for each of these:
First character = 9 options {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
Second character = 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
Third character = 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
Fourth character = 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
The total number of different combinations is just the product of these 4 numbers:
C = 9×10×10×10 = 9,000
So, we can conclude that the correct option is D.

What is the area of a square enclosure that uses 320 meters of fencing?
Answer:
A = 6400 m²
Step-by-step explanation:
the sides s of a square are congruent , then
s = 320 ÷ 4 = 80 m
tahe area (A) of a square is calculated as
A = s² = 80² = 6400 m²
The required area of square, having side 80 meters, is 6400 square meters.
What is square ?A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral. The square's angles are at a straight angle or 90 degrees.
Given that,
The length of fencing enclosure a square = 320 meters,
Let the side of the square is a meter,
According to given condition, perimeter of square,
4a = 320

If (8,b) Is a solution to the equation represented by the graph below, what is the value b?
Answer:
b= -18
Step-by-step explanation:
See attached image.
Formulate the equation for the line by calculation the slope and adding the y-intercept, as shown. The y-intercept if the value of y when x = 0. The equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept. Note that this b is not the same b in the question (8,b). The b in the question may be calculated once the equation is found: y = -3x+6, where -3 is the slope and 6 is the y-intercept (0,6).
Use x = 8 in this equation. y = -3(8)+6, y = -18
The point is (8,-18), so b is -18.

c. 64
d. 58
Answer:
b. 26°Step-by-step explanation:
ABE is tangent to the circle then m∡OBE = m∡OBD = 90
Then m∡OBD = 90 - 58 = 32
In the triangle DAB :
m∡CAB = m∡DAB = 180 - [m∡BDA + (m∡DBA)]
= 180 - [ 32 + (90 + 32)]
= 180 - [ 32 + ( 122) ]

B) 26°
Step-by-step explanation:
Finding ∠OBD
∠OBA = ∠OBE = 90° [tangent to the circle]∠OBE - 58° = ∠OBD∠OBD = 90° - 58°∠OBD = 32°Then, ∠ADB = ∠OBD = 32° (angles opposing equal sides OB and OD, both of which are radii of the circle.

Step-by-step explanation:
Start by doing what is in the paranthesis from right to left.
[tex]9 * 10^2 = 900[/tex]
and
[tex]4 * 10^3 = 4000[/tex]
So if we add them we get:
[tex]900 + 4000 = 4900[/tex]
Now to put it into standard form we just put a decimal to the right of the first number and see how many times we need to move right in order to make the number. In this case it's 3 times so we tack on × [tex]10^3[/tex]

The mean of 4, 10, 3, 6, a, 9 and 10 is 7, find the value
of a
Answer:
The value of a is 7.
Step-by-step explanation:
To calculate mean, add all of the numbers in the set and divide by the number of terms in said set. There are 7 numbers in this set, so the equation can be set up as follows.
(4 + 10 + 3 + 6 + a + 9 + 10)/7 = 7
Simplify the terms on the top.
(42 + a)/7 = 7
Multiply both sides by 7.
42 + a = 49
Subtract both sides by 42.
a = 7.
Proof:
(4 + 10 + 3 + 6 + a + 9 + 10)/7 = 7
Substitute variable.
(4 + 10 + 3 + 6 + 7 + 9 + 10)/7 = 7
Add in the parenthesis.
49/7 = 7
Divide.
7 = 7.
