Solve for x and graph the solution on the number line.
As a single inequality, we can write the solution of the given compound inequality as → x ≥ 8.
What are two types of inequalities?There are two types of inequalities -
Strict inequalities : The inequalities that have < or > symbol between the L.H.S and R.H.S.
Slack inequalities : The inequalities that have ≤ or ≥ symbol between the L.H.S and R.H.S.
Given in the question are two inequalities as mentioned below -
-2x - 3 < -1 and -2x - 3 ≤ -11
In this question → -2x - 3 < -1 is a strict inequality and -2x - 3 ≤ -11 is a slack inequality. We will solve them one by one.
Inequality - 1
- 2x - 3 < - 1
Add 3 on both sides -
- 2x - 3 + 3 < - 1 + 3
- 2x < 2
Multiply by -1/2 on both sides -
x > - 1
Inequality - 2
-2x - 3 ≤ -11
Add 3 on both sides -
-2x ≤ -8
Multiply by -1 on both sides -
2x ≥ 8
Divide by 2 on both sides -
x ≥ 8
Now, we have two inequalities -
x > - 1 and x ≥ 8
We can write it as one equality -
x ≥ 8
Therefore, as a single inequality, we can write the solution of the given compound inequality as → x ≥ 8.

In March, a family starts saving for a vacation they are planning for the end of August. The family expects the vacation to cost $ 1375 . They start with $125 . Each month they plan to deposit 20% more than the previous month. Will they have enough money for their trip? If not, how much more do they need?
Will they have enough money for their trip?Yes.They will have $1407.35
If not, how much more do they need?
Given:
a1 = $125
r = 1.25
n = 6(march-august)
[tex]S_n=\frac{a(1-r^{n})}{1-r} \\\\S_6=\frac{125(1-(1.25)^{6})}{1-1.25}\\\\S_6=1407.35[/tex]
The family will have $1407.35 after making the final deposit in August.
So, they will have enough money for their trip.
They have an additional amount of $32.35 ($1407.35-$ 1375)

In Δ SZU, UJ = 9, VI = 3 , and ZT = 18 then the value of SV = 9.
What is meant by centroid theorem?The triangle's centroid is the point where the three medians intersect. According to the centroid theorem, the centroid is 23 times the distance from each vertex to the midpoint of the opposite side.
The centroid has the unique property that the distance from a vertex to the centroid is twice that of the distance from the centroid to the midpoint of the side opposite that vertex for each median. In addition, the three medians of a triangle divide the triangle into six equal-area regions.
Given: In Δ SZU, UJ = 9, VI = 3 , and ZT = 18 .
Since ZV ≅ VU, Y is the midpoint of UZ and SV is a median of Δ ZSU. Similarly, points Y and T are also midpoints of SZ and SU, respectively, so YU and ZT are also medians. Therefore, point J is the centroid of
Δ ZSU and, according to the Centroid Theorem, SJ is 2/3 of SV.
SJ = 2/3 (SV)
= 2/3 (SJ + VJ)
simplifying the above equation, we get
(3SJ/2) - SJ = VJ
SJ/2 = 3
SJ = 4.5
Therefore, to find SV, we can now add SJ and VJ
SV = SJ + VJ
= 6 + 3
= 9
Therefore, the value of SV = 9.

Explanation below.
Step-by-step explanation:
1. The 2 ends in the hundredths place, so we place that over 100.
0.02 = 2/100
2. 2/100 can be simplified with the Greatest Common Factor of 2 and 100 which is 2. So divide 2 on the numerator and denominator.

Determine whether the following are mutually exclusive. Explain.
choosing a triangle that is equilateral and a triangle that is equiangular
Not mutually exclusive. If a triangle is equilateral, it is also equiangular.
Which of these triangles has equal sides?
An equilateral triangle, which is frequently referred to as a "regular" triangle, is a triangle with three equal-length sides. Because all three sides of an isosceles triangle are equal, an equilateral triangle is a particular case of an isosceles triangle. There are three equal sides to an equilateral triangle.Any two sides that are equal have equal opposite angles since every equilateral triangle is likewise an isosceles triangle.
As a result, because an equilateral triangle has equal lengths on each of its three sides, its three angles are also equal.
As a result, every equiangular triangle is an equilateral triangle.

Find the volume of a cube with a side of 6 cm. It has a mass of 457 g. Find its density and label with correct units.
Answer: 8.1 g/cm
Step-by-step explanation:
Density is equal to mass divided by volume. You are given a mass of
64.7
grams. You can find the volume of the cube by doing height multiplied by width multiplied by the depth.
Because all of the sides of a cube are the same length, the volume just ends up being
(2 cm) = 8 cm
Now plug both of those numbers into your density equation
p= m/v = 64.7 g/8 cm = 8.1 g/cm
~Hope this helps ;0~
Answer:
[tex]2.11 \: \: gram \: per \: cm {}^{3}[/tex]
The density is 2.11 g/cm^3
Step-by-step explanation:
Density is the ratio of the mass of a body per volume. To find density we need mass and volume.
side given (l) =6 cm
Volume of the cube = l^3
= 6^3
= 6 * 6 * 6
= 216 cm^3
we have mass = 457 g
Now,
density= mass/volume
= 457/216
=2.11
Soo, the density is 2.11 g/cm^3

There are 24 baseball teams in a league.
Each team plays two matches against each of the other teams.
Work out the total number of matches played?
(I have already tried writing 552 but it marking it wrong).
There are 534 played games in total.
How to get the total number of matches played?
There are 24 teams, and each team plays 2 matches against each one of the other teams.
So, let's say that each team is called team 1, team 2, team 3, ..., team 24.
If we start with team 1, they will play 2 games with each one of the other 23 teams, so here we will have: 23*2 = 46 games.
Now we go to team 2, we already counted the 2 games that the played with team 1, so we only look at the remaining 22 teams, here we will have:
22*2 = 44 more games.
Now with team 3, there are 21 teams remaining, so here we add another 2*21 = 42 games
And so on, now we do that for all the teams and then add all the numbers of games, the total number of games will be given by:
N = 2*(23 + 22 + 21 + ... + 2 + 1) = 534
There are 534 played games in total.

A transversal is a line that intersects two parallel lines (or lines of side) at different intersecting points, forming angles.
Parallel lines can be easily identified using the following basic properties and characteristics:
Parallel lines are always have straight lines with an equal distance between each other.
They are coplanar lines.
They never intersect, like transversal.
If there is a transversal line that show two parallel lines at two different points, it will structure 4 angles at each point.
The corresponding angles structured by the two parallel lines and a transversal are equal.
Linear equations are generally represents by the slope-intercept represented by the equation .

Determine whether the statement is always, sometimes, or never true. Explain your reasoning.
The geometric mean for two positive integers is another integer.
The statement is sometimes true.
The given statement is ' The geometric mean for two positive integers is another integer.'
Geometric mean of two integers is the square root of their product.
If a and b are two integers, then geometric mean = [tex]\sqrt{ab}[/tex]
Its value need not be an integer always. In some cases the statement fails.
For example, let a = 3 and b = 6
Then geometric mean = [tex]\sqrt{3 \times 6} = \sqrt{18}[/tex] = 4.24, which is not an integer.
Now if a and b are equal numbers, we will get an integer as the geometric mean. Because then their product will be a perfect square and taking square root, we get the same number as the geometric mean.
Also consider a = 9 and b = 4
Then their geometric mean = [tex]\sqrt{36}[/tex] = 6
So sometimes the statement is true but not always.
