Which inequality represents the graph?
Answer:
y ≤ x - 2
Step-by-step explanation:
Using the coordinate points on the graph (0, -2) and (2,0)
The general equation of the line will be y = mx+b
Slope m = 0-(-2)/2-0
m = 2/2
m = 1
From the coordinate (0, -2), this shows that the y intercept is -3
Get the equation
y = 1x + (-2)
y = x - 2
Since the line is a thick line and shaded towards the negative y-axis, the required inequality expression will be y ≤ x - 2

The last can be any of the 5 odd digits
Since there is no restriction in selection;
The [tex]second[/tex] can be [tex]any[/tex] of [tex]the[/tex] 10 digits

Answer:
[tex](\sqrt{6}+\sqrt{3})(\sqrt{6}-\sqrt{3})=3[/tex]
[tex](\sqrt{5}-\sqrt{2})(\sqrt{2}+\sqrt{5})=3[/tex]
Step-by-step explanation:
We want to simplify the expression:
[tex](\sqrt{6}+\sqrt{3})(\sqrt{6}-\sqrt{3})[/tex]
Notice that this is the difference of two squares pattern. Namely:
[tex]a^2-b^2=(a+b)(a-b)[/tex]
If we let a = √6 and b =√3, we acquire:
[tex](a+b)(a-b)[/tex]
Expand accordingly:
[tex]=a^2-b^2[/tex]
Back-substitute:
[tex]=(\sqrt{6})^2-(\sqrt{3})^2[/tex]
Simplify:
[tex]=6-3=3[/tex]
For the second expression, we have a similar pattern:
[tex](\sqrt{5}-\sqrt{2})(\sqrt{2}+\sqrt{5})[/tex]
We can first rewrite the expression (commutative property):
[tex]=(\sqrt{5}-\sqrt{2})(\sqrt{5}+\sqrt{2})[/tex]
And if we let a = √5 and b = √2:
[tex]=(a-b)(a+b)[/tex]
Expand accordingly:
[tex]=a^2-b^2[/tex]
Back-substitute and simplify:
[tex]=(\sqrt{5})^2-(\sqrt{2})^2=5-2=3[/tex]
Here is some information about a holiday.
7 night holiday
$340 per person
8% discount if you book before 31 March
On 15 February, Naseem books this holiday for 2 people.
Calculate the total cost of his holiday.
Answer:
$625.6
Step-by-step explanation:
Information about a holiday:
7 night holiday
$340 per person
8% discount if you book before 31 March
Number of people Naseem booked the holiday for = 2
Date of booking of the holiday = February 15
Total cost of the holiday per person = cost per person - discount before March 31
= $340 - 8% of $340
= 340 - 8/100 * 340
= 340 - 0.08 * 340
= 340 - 27.2
= $312.8
Total cost of the holiday for 2 persons = 2 × Total cost of the holiday per person
= 2 * $312.8
= $625.6
How to find the slope of a line passing through (-3,3) , (-5,9)
Answer:
slope = - 3
Step-by-step explanation:
[tex]slope, m = \frac{y_2 - y_1}{x_2 - x_ 1}[/tex] , [tex][ \ (x_ 1 , y_ 1 ) = ( -3 , 3 ) , \ (x_2 , y _ 2 ) = ( - 5 , 9 ) \ ][/tex]

Answer:
"D" (the fourth one....(7,1),(6,2)....
a "function" is a very specific relationship in math...
for a relationship to be "a function" every possible INPUT (x-values) has to map (correspond) to a UNIQUE output value (Y-value)
a line is a function (all x's have unique y values.
A circle is NOT ..... at the center (x-value) there are two y values (one above and one below)
in your problem answer "D" the "x-value" "5" has two different "y-values"

8p²-18p² need help from brainliest
Answer:
- 10p2
Step-by-step explanation:
p(8p - 18 p)
p x -10p
ans = -10p2
Answer: -10p²
This is the same as saying -10p^2
============================================
Explanation:
Both terms 8p² and -18p² are like terms.
We combine them in much the same way as 8-18 = -10, just with a p² attached to everything.
So 8p² - 18p² = (8-18)p² = -10p²
The coefficient -10 is negative because we're subtracting small minus big. If it was the other way around, then we'd get a positive value.
At which angle will the hexagon rotate so that it maps
onto itself?
O 60°
90°
0 120°
O 180°
Answer:
60 degress
Step-by-step explanation:
Edgen 2021
60° is the angle at which the hexagon rotate so that it maps onto itself.
What is Polygon?A polygon is a plane figure made up of line segments connected to form a closed polygonal chain.
When a figure has a rotational symmetry, it maps onto itself under rotation about a point at the centre.
When an hexagon rotate onto itself,the vertices must cover to vertices and from sides to sides.
There are six angles in a hexagon and the sum of the angles is 360°. Therefore, each angle has a measure of 360°/6 is equal to 60°.
Rotating subsequently by 60 degree will rotate a hexagon onto itself. A hexagon has 6 rotations, that is, a hexagon has a rotational symmetry of 6 and at angle 60°, the hexagon will rotate onto itself.
Hence, 60° is the angle at which the hexagon rotate so that it maps
onto itself.

At noon, the temperature at a mountaintop research center is 11 degrees. Overnight the temperature drops to -19 degrees. Which expression represents how much the temperature changed?
a. |19|
b. |-19|
c. |-30|
d. |-38|
Answer:
c. |-30|
Step-by-step explanation:
It wants the change from 11 to -19. While normally absolute value is the distance from zero, zero can be shifted. Depending on where you are in learning about absolute value, the midway point can change from zero to, say, 4. This is called a transformation and is typically represented on a graph. Simple answer is that zero is shifted to 11. Therefore, absolute value changes from distance away from zero, to distance away from 11.

Write an in Standard Folm given the following points:
(-2, 6), (9,8)
Answer:
2/11 x + 70/11
Step-by-step explanation:
Given the coordinate (-2, 6), (9,8), the equation in standard form is of the form y = mx+b
m is the slope = 8-6/9-(-2)
m = 2/11
Get the y-intercept
Substitute m = 2/11 and (-2, 6) into the expression y = mx+b
6 = 2/11(-2)+b
6 = -4/11 + b
b = 6 + 4/11
b = (66+4)/11
b = 70/11
Get the required equation
y = 2/11 x + 70/11
Hence the required equation is 2/11 x + 70/11

What is the value of x?
2

7
Answer:
x = 2
Step-by-step explanation:
AE is equal to the sum of AB and BE because of segment addition postulate, we can substitute to get AE = 11 + x + 1 = x + 12
DE is equal to the sum of DC and CE because of segment addition postulate, we can substitute to get DE = 1 + x + 4 = x + 5
To solve the problem, we can use power of a point, more specifically exterior secants products scenario. In this case, we can get the equation:
AE * BE = DE * CE
Now, we can substitute and solve:
(x + 12)(x + 1) = (x + 5)(x + 4)
x^2 + 13x + 12 = x^2 + 9x + 20
13x + 12 = 9x + 20
4x + 12 = 20
4x = 8
x = 2

Answer:
66 in^2
Step-by-step explanation:
Imagine that the figure is a whole square, where the space between is filled in.
Find the area of the imaginary square (l x w):
9 in. x 9 in. = 81 in^2
Lets make that whole square the original figure it used to be (take away the space we “filled in”)
Lets find the area of the space we filled in:
5 in x 3 in= 15 in^2
Subtract the imaginary square’s area by the area of the space that was originally blank:
81 in^2 - 15 in^2 = 66 in^2
66 in^2 IS YOUR FINAL ANSWER, that is the real area of the composite figure you have.
