Answer: All Numbers Are Real Solutions (Note - Have An Amazing Day! :)
Comment If I'm Wrong!
Step-by-step explanation:
4(3x+5)=5(x+4)+7x
4(3x+5)=5(x+4)+7x
(4)(3x)+(4)(5)=(5)(x)+(5)(4)+7x
12x+20=5x+20+7x
12x+20=(5x+7x)+(20)
12x+20=12x+20
12x+20=12x+20
12x+20−12x=12x+20−12x
20=20
20−20=20−20
0=0
Answer: All real numbers are solutions
Answer:
x = 0
Step-by-step explanation:
D = (-8, -3), D' = (8, -3)
The line of reflection is the perpendicular bisector of the segment between these points. In order to find that, we need to know the slope and midpoint of the segment DD'.
<u><em>Slope</em></u>
The slope of the line DD' is ...
... m = (change in y)/(change in x) = (-3 -(-3))/(8 -(-8)) = 0/16 = 0
The line through point D with slope 0 is ...
... y = 0(x -(-8)) +(-3)
... y = -3
<u><em>Midpoint</em></u>
The midpoint of the segment DD' is the average of their coordinates:
... M = (D +D')/2 = ((-8, -3) +(8, -3))/2 = (-8+8, -3-3)/2 = (0, -3)
<em><u>Perpendicular bisector</u></em>
The line perpendicular to the horizontal line y=-3 through the point M = (0, -3) will be a vertical line of the form ...
... x = constant
The x-coordinate of the point (0, -3) tells us the constant, so the line of reflection is ...
... x = 0
Answer:
3.33 miles per hour
Step-by-step explanation:
The total distance traveled by the hiker is 5 * 2 = 10 miles, and the total time travelled is 2 + 1 = 3 hours.
So, to find the average speed of the entire trip, we can use the formula:
distance = speed * time
With distance = 10 and time = 3, we have:
10 = speed * 3
speed = 10/3 = 3.33 miles per hour.
Answer:
38.5
Step-by-step explanation:
to find the area of the triangle, you can do 11 x 3 ÷ 2 = 16.5
then you find the area of the triangles: 3 x 3 = 9
and 3 × 11 = 33
then you add them all to find a total area of 38.5
The answer is b. m^2/3.n^5/3
