1. x - 1 =
x = +1
x =
2. 8x - 5 =9
8x = 9 - 5
8x = 4
x =
3. 2 =
= x
=

Answer:
6. First choice
7. Second choice
Step-by-step explanation:
For number 6, The first choice has a closed circle and the arrow goes to the right, meaning greater than or equal to
For number 7, all values are include except where the open circle is
Answer:
23.92°, 78.503°, and 77.577°
Step-by-step explanation:
The coordinates of the vertices of the triangle are;
X(-3, -5), Y(2, 6), Z(6, 3)
The vectors are;
z = =
y = =
x = =
Therefore, we get;
α = arccos(0.91490) ≈ 23.92°
γ = The angle between -y and x
-y =
We get;
Therefore;
γ = arccos(0.199309) ≈ 78.503°
γ ≈ 78.503°
By angle sum property, β = 180° - (α + β)
β ≈ 180° - (23.92° + 78.503°) = 77.577°
β ≈ 77.577°
The interior angles are;
23.92°, 78.503°, and 77.577°
does that give you options or choices dowen there so I can answer your question
Answer:
Please check explanations for answer
Step-by-step explanation:
To answer this, we need to understand something
Firstly is that we have dotted lines of the inequality line does not have an equal
to
And also, the solution is directly related to the inequality sign. If it states greater than, solution will be greater than (above the line). If it states less than, solution will be less than (below the line)
So let us take the inequalities one after the other from left to right
1. solid line and below the line
2. dotted lines and above the line
3. solid line and above the line
