Answer:
a) |e-93|≤1.55; 91.45 ≤ e ≤ 94.55
b) see below
Step-by-step explanation:
a) Let e represent the distance from the sun to the earth in millions of miles. The table tells us the average distance is 93.0 million miles, and the difference from that value can be as much as 1.55 million miles. The corresponding inequality is ...
|e-93.0| ≤ 1.55
We can solve this by rewriting it as a compound inequality.
-1.55 ≤ e -93.0 ≤ 1.55
91.45 ≤ e ≤ 94.55 . . . . . . add 93
__
b) An absolute value equation will give a finite number of particular values as its solution. The question asks for a range of values. An absolute value inequality is well-suited to providing a solution that is a range of values.

“To graph y=2/3x+4, Emaan plots one point at (0,4) and a second point 2 units right and 3 units up at (2,7). He then draws a line through (0,4) and (2,7). What error did Emaan make?”
The “2/3x” area is meant to be a fraction.
Answer:
The error he made was adding 3 to the y value and adding 2 to the x value, instead of adding 2 to the y value and 3 to the x value.
Step-by-step explanation:
The slope can also be called "rise over run," or the change in y divided by the change in x.
In this situation, the slope is 2/3, meaning that a change in y of 2 units will increase the x value by 3 units.
Emaan switched these values when plotting the points, and did a change in 2 x values with a change in 3 y values.
From the point (0, 4), instead of plotting the point (2, 7), he should have plotted (3, 6).
The error he made was adding 3 to the y value and adding 2 to the x value, instead of adding 2 to the y value and 3 to the x value.

Name the multiplicative identity of -12i
Answer:
0
Step-by-step explanation:
The multiplicative identity of -12i is (1 + 0i) or 1.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
-12i
This is a complex number.
The multiplicative identity is the value when multiplied by the given value gives the same value.
Now,
(1 + 0i) x -12i = -12i
Thus,
1 + 0i or 1 is the multiplicative identity.

Answer:
30.32 miles
Step-by-step explanation:
This is a four-part question.
First, you need to find the distance between all of the places.
Alanah to Mia:
Find the hypotenuse: 6^2+8^2= C^2
(After work: C=10)
Mia to Teresa:
14 miles (You can just count.)
Teresa to Arena:
Find the hypotenuse: 2^2+6^2= C^2
(After work: 6.32)
Then, you can add them all up!
10+14+6.32= 30.32 miles (your answer).
Answer:
30 8/25 or 24 + √40
Work:
Alanah to Mia:
We have a right triangle, so do a² + b² = c²
6² + 8² = c²
36 + 64 = 100
100 = 10²
c = 10
Mia to Teresa:
d = 14
Just count here, it's self-explanatory.
Teresa to Arena:
Right triangle again
2² + 6² = c²
4 + 36 = 40
√40 ≈ 6.32 = 6 8/25
Final Sum:
Add 10 14 and 6 8/25 to get your final answer.
10 + 14 = 24
24 + 6 8/25 = 30 8/25 mi
Know that the fraction is just an approximation, the actual answer in radical form would be 24 + √40

Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no wind.
Answer:
6.5 mph
Step-by-step explanation:
Given that :
Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no
Wind speed = 2mph
Let time taken to skateboard = t
Speed = distance / time
Distance of 3.375miles against 2 mph wind
Let skate speed = x
skate speed - wind speed=
(3.375 miles / t) + 2mph = x - - - (1)
Distance of 6.375miles with 2 mph wind
(6.375 miles / t) - 2 mph = x - - - - (2)
Equate (1) and (2)
(6.375/ t) - 2 = (3.375/ t) + 2
(6.375 - 3.375) / t = 2 + 2
3 / t = 4
3 = 4t
t = 3/4
t = 0.75
Hence, speed without wind will be :
(3.375 miles / 0.75) + 2mph = x
4.5mph + 2mph = 6.5 mph
