The value of p that we get by solving the inequality given in the question is [tex]p\geq \frac{-20}{3}[/tex]
The given inequality is
[tex]\frac{3}{4}p+8\geq 3[/tex]
⇒[tex]\frac{3}{4}p\geq 3-8[/tex] (subtracting 8 on both sides)
⇒[tex]3p\geq -5*4[/tex] (multiplying both sides by 4)
⇒[tex]p\geq \frac{-20}{3}[/tex] (dividing both sides by 3)
⇒[tex]p\geq -6.667[/tex]
Therefore the value of p must be greater than or equal to -20/3 or -6.667
That is, [tex]p\geq -6.667[/tex]

Statements and reasons.
1) ∠1 and ∠3 are supplementary
Reason: This is true because it is stated in the question.
2) ∠1 + ∠3 = 180º
Reason: By statement 1, ∠1 and ∠3 are supplementary, and by definition, supplementary angles sum up 180º.
3) ∠2 = ∠3
Reason: From the picture we see that ∠2 and ∠3 are opposite congruent angles, so they are equal.
4) ∠1 + ∠2 = 180º
Reason: from statement 2 we have ∠1 + ∠3 = 180º, and from statement 3 we have ∠2 = ∠3, so we have ∠1 + ∠2 = 180º.
5) ∠1 and ∠2 are supplementary
Reason: from statement 4 we have that ∠1 sum up ∠2, so by definition ∠1 and ∠2 are supplementary.
6) line m || line n
Reason: from the picture we see that ∠1 and ∠2 are internal collateral angles of the lines m and n, and from statement 5 we know that ∠1 and ∠2 are supplementary, so we have that the angle between line m and line n is 180°, and by definition, they are parallel lines.
Summary of the reasons
1) It is stated in the question
2) By statement 1 and by definition of supplementary angles.
3) Because they are opposite congruent angles, so they are equal.
4) By statement 2 and 3.
5) By statement 4, and by definition of supplementary angles.
6) By picture ∠1 and ∠2 are internal collateral angles of the lines m and n, and by statement 5 they are supplementary so they are parallel lines.

I need to know what is the missing reason for line 7 in this proof
Similarity Theorems
Triangles ABG and DCB are similar by the AA similarity postulate
"If two angles in one triangle are congruent to two angles in another triangle, then the two triangles are similar"
The steps previous to statement 7 prove angles C and B are congruent because they are formed by two parallel lines that intersect a common line.
On the other side, angles DBC and AGB are congruent also because they are both right angles.
With two corresponding congruent angles, the AA similarity postulate is satisfied and the triangles are similar.

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options. 18 x minus 15 = 72 50 x minus 25 = 72 18 x minus 9 = 72 3 (6 x minus 3) = 72 x = 4.5
The equations with same value of x as (3/5)(30x - 15) = 72 is 18x - 9 = 72, 3(6x - 3) = 72 and x = 4.5
How to solve an equation?An equation shows the relationship between two or more numbers and variables.
Given the equation:
(3/5)(30x - 15) = 72
Opening the parenthesis:
18x - 9 = 72
Factorizing the equation:
3(6x - 3) = 72
Dividing through by 3:
6x - 3 = 24
6x = 27
Dividing through by 6:
x = 4.5
The solution to the equation (3/5)(30x - 15) = 72 yields x = 4.5

The slope of the line is represented by the word m which is obtained as 0.5.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
To determine a line's inclination or steepness, use the slope formula. Calculating the ratio of the change in the y-axis to the change in the x-axis may be used to calculate the slope of any line.
From the graph, the data is observed as,
(x₁,y₁)=(0,1)
(x₂,y₂) = (-2,0)
The slope of the line is found as,
[tex]\rm m =\dfrac{0-1}{-2-0} \\\\ m = 0.5[/tex]
Thus, the slope of the line is represented by the word m which is obtained as 0.5.

there is a linear relationship between the distance that a car drives and the amount of gas left in the tank of the car. the value of r2 for this linear relationship is 98.01%. what is the value of r?
A linear relationship between the distance that a car drives and the amount of gas left in the tank of the car is negative, and the value of r is -0.99
A linear relationship between the distance that a car drives and the amount of gas left in the tank of the car are negative because when a car travels a distance, it consumes fuel, and so fuel decrease with distance
Calculating the value of r
Given, r^2=98.01%
r^2=0.9801
r=±√0.9801
r=±0.99
Since r should be negative, so we pick the negative value and reject the positive value
