how many solutions -4(x+5)=-4x-20
Answer:
Infinite number of solutions. The equations and answers are the same no matter what number x you plug in.
Step-by-step explanation:
-4(x + 5) = -4x - 20
-4x - 20 = -4x - 20
0 = 0
[tex]\text{Hello there! :)}[/tex]

A Toyota Prius and a Dodge Circuit leave an intersection at the same time. The Prius heads east at an average speed of 50 miles per hour, while the Circuit heads south at an average speed of 45 miles and hour. After 30 minutes, the two cars are about _____ miles apart. After 2 hours, the two cars are about ______ miles apart. Write an express for the distance, d (in miles) after t hours.
Answer:
33.634 ; 134.536 ; d = √[(50t)² + (45t)²]
Step-by-step explanation:
Given the following :
Toyota Prius = East at 50mph
Dodge Circuit = South at 45mph
Distance apart after 30 minutes :
Distance = speed * time
Distance moved by Prius = ( 50mph × 0.5hr) = 25 miles
Distance moved by Circuit = ( 45mph × 0.5hr) = 22.5 miles
Hence Displacement after 30 minutes :
d = √(25² + 22.5²)
d = √625 + 506.25
d = √1131.25
d = 33.634 miles
Distance apart after 2 hours :
Distance = speed * time
Distance moved by Prius = ( 50mph × 2hr) = 100 miles
Distance moved by Circuit = ( 45mph × 2hr) = 90 miles
Hence Displacement after 2 hours :
d = √(100² + 90²)
d = √10000 + 8100
d = √18100
d = 134.536 miles
Distance d in miles after t hours :
d = √[(50t)² + (45t)²]

5. A circle has a diameter of 8.2 inches. Find its circumference?
in a test consisting of 90 questions, Ama answered 75% of the first 40 questions correctly. If she had to get a score of 80% in the test, (i) how many questions did she answer correctly out of the first 40 questions? (ii) how many questions should she answer correctly out of the 90 questions? (iii) what percentage of the remaining 50 questions should she answer correctly in order to get the 80%?
Answer:
total question =90
she obtained 75% of first 40 questions
No. of question she got correct in first 40 = 75% * 40 = 302. in order to get 80% out of 90,
the no. of questions got correct by Ama = 80% * 90 = 72
3. As she already got 30 c0rrect in first 40 questions, the number of question she needs correct for remaining 50 = (72-30) = 42
percentage = 42/50*100% = 84%
The number of questions answered correctly on the first 40 questions is 30.
The questions answered correctly of the 90 questions is 72.
The percentage answered correctly on the last 50 questions is 84%.
How many questions were answered correctly?Percentage can be described as a fraction of an amount expressed as a number out of hundred.
Number of questions answered correctly on the first 40 questions: 40 x 0.75 = 30
Questions answered correctly of the 90 questions: 90 x 0.8 = 72
Number of questions gotten correctly on the last 50 questions: (0.8 x 90) 30 = 42
Percentage = 42/50 x 100 = 84%

Emily and Hunter tracked the average temperature in their city for the past 8 days. They recorded their temperature findings in this list 66°F, 57°F, 61°F, 65°F, 54°F, 62°F, 59°F, 56°F
What is the mean absolute deviation of this data set?
Enter your answer in the box.
Answer:
The mean absolute deviation = 3.5°F
Step-by-step explanation:
The sum of the given temperatures, ∑T, is found as follows;
∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F
The number of days, n, over which the temperature was tracked = 8 days
Therefore, the mean, [tex]\bar x[/tex], of the data set = ∑T/n = 480°F/8 = 60°F
The mean absolute deviation is given by the following formula;
[tex]Mean \ absolute \ deviation = \frac{\sum \limits_{i = 1}^{n} \left | x_i - \bar x \right | }{n}[/tex]
Therefore, we have;
66 - 60 = [tex]\left | 6\right |[/tex] = 6
57 - 60 = [tex]\left | -3\right |[/tex] = 3
61 - 60 = [tex]\left | 1\right |[/tex] = 1
65 - 60 = [tex]\left | 5\right |[/tex] = 5
54 - 60 = [tex]\left | -6\right |[/tex] = 6
62 - 60 = [tex]\left | 2\right |[/tex] = 2
59 - 60 = [tex]\left | -1\right |[/tex] = 1
56 - 60 = [tex]\left | -4\right |[/tex] = 4
The mean absolute deviation is therefore;
The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.
Geometry Basics Unit 1 - Please Help
Answer: 24
Step-by-step explanation:
if line BD = line BC, then
5x - 26 = 2x + 1
3x = 27
x = 9
so if you plug that pack into the original equation for line BC (2x + 1), then line BC is 19 units long. now, subtract that from AC to find the length of AB:
43 - 19 = 24 units
A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 6 feet per second. The elevator for the miners descends 16 feet per second. One day, the equipment elevator begins to descend. After 28 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 14 seconds? At that time, which elevator is deeper?
Answer:
equipment: -252 feet; miners: -224 feetequipment is deeperStep-by-step explanation:
The attached graph shows the depth of the elevators with respect to the time the miners' elevator started.
After 14 more seconds, the positions are ...
equipment: -6(42) = -252 feet relative to the surface
miners: -16(14) = -224 feet relative to the surface
The equipment elevator is deeper.

What is the domain and range in this graph?
Step-by-step explanation:
The graph starts when the value of x is -1 and ends when it's value is 5 , So domain is [-1,5]
The highest value of the graph is 4 which is at x = -1 and the lowest value of the graph is 0 , which is at x = 5, So range is [0,4]
The domain is equal to all the input values (x-values)
The range is equal to all the output values (y-values)
In this problem,
The domain: [-1, 5]
The range: [0, 4]

HELP PLEASE TIMED This graph displays a linear function. Interpret the constant rate of change of the relationship. Rate of change = BLANK
Answer:
3
Step-by-step explanation:
The rate of change is just another way of saying slope.
The slope of a line is it’s rise over run.
We can see here that every time x increases by 1, y increases by 3. (This is where the triangle comes in handy).
Rise:3
Run:1
[tex]\frac{3}{1}=3[/tex]
So the rate of change is 3.
