The sum of the distances of R to Q and P to Q is 9 units.
Solution:
Given points are P(–3, 6), Q(3, 6) and R(3, 3).
Distance between two points formula:
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance from R to Q:
Here [tex]x_1=3, y_1=3, x_2=3, y_2=6[/tex]
Substitute these in the given formula, we get
Distance = [tex]\sqrt{(3-3)^2+(6-3)^2}[/tex]
[tex]=\sqrt{0+9}[/tex]
= 3 units
Distance from R to Q is 3 units.
Distance from P to Q:
Here [tex]x_1=-3, y_1=6, x_2=3, y_2=6[/tex]
Substitute these in the given formula, we get
Distance = [tex]\sqrt{(3-(-3))^2+(6-6)^2}[/tex]
[tex]=\sqrt{36+0}[/tex]
= 6 units
Distance from P to Q is 6 units.
Sum of the distances = 3 + 6 = 9 units
Hence the sum of the distances of R to Q and P to Q is 9 units.

-6(2x -4)
-(12x -6) +18
-3(4x -3) +15
-4(3x +6)
Answers
-4(3x + 6) is not equivalent to other expressions
Solution:
Let us use the distributive property to get the equivalent expression
Distributive property is represented as:
a(b + c) = ab + ac
First expression:[tex]-6(2x - 4) = (-6 \times 2x) + (-6 \times -4) = -12x + 24[/tex]
Second expression:Using distributive property,
[tex]-(12x - 6) + 18 = -12x + 6 + 18 = -12x + 24[/tex]
Third expression:Solve the expression using distributive property
[tex]-3(4x-3) + 15 = ((-3 \times 4x)+(-3 \times -3)) \\\\-3(4x-3) + 15= -12x + 9 + 15 \\\\-3(4x-3) + 15=-12x + 24[/tex]
Fourth expression:[tex]-4(3x + 6)= -4 \times 3x + -4 \times 6\\\\-4(3x + 6)= -12x -24[/tex]
Thus fourth expression is not equivalent to other expressions

Terrence and Lee were selling magazines for a charity. In the first week, Terrance sold 30% more than Lee. In the second week, Terrance sold 12 magazines, but Lee did not sell any. If Terrance sold 50% more than Lee by the end of the second week, how many magazines did Lee sell? Choose any model to solve the problem. Show your work to justify your answer.
Answers
Answer:
Lee sold 60 magazines
Step-by-step explanation:
1st week:
Lee sold = x magazines
Terrence sold [tex]=x+0.3x=1.3x[/tex] magazines (30% more)
2nd week:
Lee sold = 0 magazines
Terrence sold = 12 magazines
Total:
Lee sold = x + 0 = x magazines
Terrence sold = 1.3x + 12 magazines
If Terrance sold 50% more than Lee by the end of the second week, then
x - 100%
1.3x + 12 - 150% (50% more), then
[tex]\dfrac{x}{1.3x+12}=\dfrac{100}{150}\\ \\150x=100(1.3x+12)\\ \\150x=130x+1,200\\ \\150x-130x=1,200\\ \\20x=1,200\\ \\x=60[/tex]
Hence, Lee sold 60 magazines

A triangle has the length of 6cm and height of 8cm. The area of the rectangle is 5 times the area of the triangle. The rectangle has the length of 12cm. Work out what the width is.
Answers
Area of rectangle = 120
therefore, w x 12 = 120
w = 10
Answer:
10cm
Step-by-step explanation:
Since the area of the rectangle is 5times the area of the triangle, let us first of all find the area of the triangle.
From the question, we obtained the following information:
h = 8cm
b =6cm
Area of triangle = 1/2 x b x h
Area of triangle = 1/2 x 6 x 8
Area of triangle = 24cm^2
But,
Are of the rectangle = 5times the area of triangle i.e
Area of rectangle = 5 x 24 = 120cm^2
Area of rectangle = L x w
L = 12cm
Area of rectangle = 120cm^2
W =?
120 = 12 x w
Divide both side by 12
W = 120 /12 = 10cm

3 What is the y-intercept of the line perpendicular to the line y = -3/4x + 5 that includes the point (-3, –3)?
Answers
The y-intercept of the line perpendicular to y = -3/4x + 5, passing through the point (-3, -3), is 1. This is found by first determining the slope to be 4/3, and then using the point-slope form equation to solve for the y-intercept when x is zero.
To find the y-intercept of the line perpendicular to the line y = -3/4x + 5 that passes through the point (-3, –3), we must first determine the slope of the perpendicular line. Since perpendicular lines have slopes that are negative reciprocals of each other, the slope of the perpendicular line would be 4/3 (since the negative reciprocal of -3/4 is 4/3).
Next, we can use the point-slope form of the equation of a line to find the equation of the perpendicular line. The point-slope formula is y – y1 = m(x – x1), where (x1, y1) is a point on the line and m is the slope of the line. Substituting the given point and the slope into the formula, we get y – (–3) = 4/3(x – (–3)), which simplifies to y + 3 = 4/3(x + 3).
To find the y-intercept, set x to 0 and solve for y. Doing so, we obtain y + 3 = 4/3(0 + 3), or y + 3 = 4. Subtracting 3 from both sides, we find the y-intercept to be y = 1.

Alan, Brady and Matt shared 740 marbles. Alan has 20 fewer marbles than Brady and 120 fewer marbles than Matt. How many marbles did Alan have?
Answers
Answer:
[tex]200 \ marbles[/tex]
Step-by-step explanation:
[tex]Let\ Alan\ have\ =x\ marbles\\Brady\ have = (x+20)\ marbles\\Matt\ have = . (x+120)\ marbles\\\\Total\ marbles = 740\\x+(x+20)+(x+120)=740\\x+x+20+x+120=740\\3x+140=740\\3x=740-140\\3x=600[/tex]
Dividing [tex]3[/tex] both sides.
[tex]\frac{3x}{3}=\frac{600}{3}\\\\x=200[/tex]
We solve the problem by setting up a linear equation based on the information given. We solve it to find that Brady has 260 marbles and then deduct or add from this number to find the number of marbles for Alan and Matt. Our answer is that Alan has 240 marbles.
Explanation:This problem involves solving linear equations in order to find the number of marbles each person has. Firstly, we need to represent each person's marbles in terms of the other person's marbles as given in the question.
Let's say Brady has 'b' marbles. From the problem, we deduce that Alan has 'b-20' marbles (20 less than Brady). We can also deduce that Matt has 'b-20+120' marbles (120 more than Alan).
Given that the total number of marbles is 740, we can set up the equation b + (b - 20) + (b - 20 + 120) = 740. Solving this linear equation, we get b = 260. Then, substituting b in the expressions for Alan and Matt will give us the number of marbles for each person, implying Alan has 260 - 20 = 240 marbles.

Graph the function f(x)=5−1.5x
Answers
The function f(x) = 5 - 1.5x can be graphed by calculating the y values for a set of x-values, plotting these points, and drawing a straight line that connects them, as it is a linear function with a slope of -1.5.
Explanation:To graph the function f(x) = 5 - 1.5x, we can start by finding values for x and calculating the corresponding y-values. For instance, when x = 0, f(x) = 5 - 1.5*0 = 5. When x = 1, f(x) = 5-1.5*1 = 3.5. So, we can plot these points (0,5) and (1,3.5) respectively.
Next, because this is a linear function (it has the form y = mx + b), these points should form a straight line. Simply draw a line that passes through these points. Further, this function has a negative slope of -1.5 which means the line should be falling as it moves from left to right.
The x-axis and the y-axis must be labelled distinctly and the scale should be defined according to the maximum and minimum values of x and y observed.
Note: Without any restrictions on the domain mentioned, we assume that x is a real number and therefore, the graph stretches infinitely in both directions.

Answers
Answer:
i think its Gas attacks allowed Germany to win major battles and defeat France before the United States
joined the war.
Step-by-step explanation:
Final answer:
Gas attacks during World War I contributed to the horrors and difficulties of trench warfare and had severe psychological impacts on soldiers, but they did not lead to major strategic victories or civilian efforts to end the war.
Explanation:
Gas attacks during World War I profoundly changed the nature of warfare, particularly during the era of trench warfare. These gas attacks made the act of fighting in trenches extremely challenging and induced significant psychological suffering among the troops. The use of poison gas was viewed as a horrific method of warfare by soldiers, burning the lungs, eyes, and skin, and leaving those who survived in a state of dread, with many considering the victims of gas attacks the unlucky ones. It did not lead to a significant shift in the outcome of battles, which remained largely stalemated with enormous casualties but minimal territorial gains.
Despite these devastating effects, gas attacks did not lead to military victories that decisively changed the war - at least not in favor of Germany before the United States entered the war, nor did these attacks result in the mass deaths of civilians or lead people to demand an immediate end to the war. The international tensions and problems that initiated the war were not resolved but were instead exacerbated by the new methods of modern combat. Gas attacks did terrify troops, but they did not lead them to demand a truce between the Allied Powers and the Central Powers.
In summary, the most apt answer to how gas attacks affected warfare during World War I would be that they made fighting in trenches difficult and had significant psychological effects upon troops, as discussed in option B.

Explain why the equation 5(2x+1)-2=6x+5 has only one solution. Then find the solution.
Answers
Answer:
10x + 3 = 6x + 5
Based on this, we have the lines y=10x+3 and y=6x+5. Both of the equations are linear, so they are straight lines when graphed. A system of straight lines can only have one solution maximum.
Solution:
x = 1/2
y = 8
(1/2 , 8)
Step-by-step explanation:
Start by expanding with the distributive property, then simplify by collecting like terms.
5(2x + 1) - 2 = 6x + 5 Multiply "5" with each term in the brackets.
10x + 5 - 2 = 6x + 5 Collect left side's like terms (5 - 2 = 3)
10x + 3 = 6x + 5
Based on this, we have the lines y=10x+3 and y=6x+5. A solution is the same as the POI (point of intersection). Both of the equations are linear, so they are straight lines when graphed. A system of straight lines can only have one solution maximum.
Some linear systems might have no solutions (when the lines are parallel) or infinite solutions (when the lines are equivalent, the same).
To find the solution, continue with the equation and isolate "x". This will give you the x-coordinate of the point of intersection.
To isolate 'x', move everything to the other side of 'x'. To move something, you do its reverse operation to both sides in reverse BEDMAS order.
10x + 3 = 6x + 5
10x - 6x + 3 = 6x - 6x + 5 Subtract 6x from both sides
4x + 3 = 5 "6x" cancelled out on the right. Simplified left (10x-6x=4x)
4x + 3 - 3 = 5 - 3 Subtract 3 on both sides. "3" on the left will cancel out
4x = 2 The right side was simplified (5 - 3 = 2).
4x/4 = 2/4 Divide both sides by 4 to isolate 'x'. Simplify right side.
x = 1/2 Solution's x-coordinate
Substitute what you found for 'x' into any equation that has 'y' (either y=10x+3 or y=6x+5). I will choose the first equation.
y = 10x + 3
y = 10(1/2) + 3 Multiply 1/2 and 10
y = 5 + 3 Add
y = 8 Solution's y-coordinate
Therefore the solution is when x=1/2 and y=8, or as an ordered pair, (1/2 , 8).

The area of the base is 34 cm². The height is 7 cm. What is the volume.
Answers
Answer:
238cm³
Step-by-step explanation:
Final answer:
To calculate the volume, multiply the given area of the base (34 cm²) by the given height (7 cm) to obtain a volume of 238 cm³.
Explanation:
The question pertains to finding the volume of a three-dimensional object. Given the area of the base of the object is 34 cm² and the height is 7 cm, the volume V can be calculated using the formula V = area of base × height.
To solve, we simply multiply the area of the base by the height:
V = 34 cm² × 7 cm = 238 cm³.
The volume of the object is therefore 238 cm³.
