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]
[tex]\large\boxed{\text{Infinite solutions.}}[/tex]
[tex]-4(x + 5) = -4x - 20\\\\\text{Simplify:}\\\\-4(x) -4(5) = -4x - 20\\\\-4x - 20 = -4x - 20\\\\\\\\\text{Add 4x to both sides:}\\\\-4x + 4x - 20 = -4x + 4x - 20\\\\-20 = -20\\\\\text{Both sides of the equal sign are the same, so:}\\\\\\\text{Infinite solutions.}[/tex]

I need someone to explain functions and functional symmetry to me. This is very important, so if you do not have a legit answer, you will get reported.
Symmetrical functions can be about the x and y axis. Essentially, if we reflect the graph across the y or x axis, we get the same graph. Some other graphs can be reflected across both the x and y axis at the same time and be symmetrical. These can be classified as odd and even functions. You can test this by replacing x and y with -x and -y and simplify the equation. If the results comes out to be the same as the original, it is symmetrical across the origin.
Best of Luck!
Answer:
a shape that has reflective symmetry either x or y axis of origin.
in other words... it's a mirror image.

The Bureau of Labor and Statistics (2018) reports that the average earner with a high school diploma will earn about $35,000 per year, an earner with a bachelor's degree will earn about $59,000 per year. The average salary of the high school graduate is what percent of the college graduate?
Answer:
59.322% or 59%
Step-by-step explanation:
devide 59,000 from 35,000 to get the answer.
After that, you will get 59% (rounded).
the answer is D (59.3%)

Statement: All integers are rational numbers.
For a science experiment, Marcia dissolved 1.0 kilogram of salt in 3.0 liters of water. For a different experiment, Bobby dissolved 2.0 pounds of salt in 7.0 pints of water. Which person made a more concentrated salt solution? Explain. Use 1 L = 2.11 pints. Round your answer to the nearest hundredth.
Step-by-step explanation:
The concentration of Marcia's solution is:
1.0 kg / 3.0 L = 0.33 kg/L
The concentration of Bobby's solution is:
(2.0 lb × 1 kg / 2.2 lb) / (7.0 pints × 1 L / 2.11 pints) = 0.27 kg/L
Therefore, Marcia's solution is more concentrated.

Which letter represents the first number in an ordered pair?
Step-by-step explanation:
Example: (5,2)
On a graph, the 5 goes on the x-axis and the 2 goes on the y-axis.
Also, in the world of variables, and the alphabet, x is before y.
So x represents the first number in an ordered pair.

Please help on number 9 and 10. Will mark brainliest.
Answer:
9. 1.24 mL
10. $5.93
Step-by-step explanation:
Question 9:
If the dosage of medicine is 0.01 mL per pound of weight of the patient, and the patient's weight is 124 pounds, we can set up an equation to solve for how much medicine the patient would need to take:
Dosage of medicine per pound of body weight x Total body weight = Total medicine required
OR
0.01 * w = m,
where w is total body weight and m is total medicine required.
To solve for the dosage the patient needs, just plug the numbers into the right places (124 for w and leave m as it is):
0.01 * 124 = m
1.24 = m
Therefore, a patient with a body weight of 124 pounds would need a 1.24 mL dosage.
Question 10:
To make the multiplication easier, we could rewrite 15% as 0.15 ( because 15% = 15/100):
0.15 * Total bill = Total tax payed for bill (Also can be written as [tex]\frac{15}{100} * 39.51[/tex])
OR
0.15*39.51 = Total tax
5.9265 = Total tax
5.93 = Total tax <-------- (rounded)

L 1. Andrew's hobby is mountaineering. He
started his hike at 250 feet above sea level.
When he reached the peak of the mountain
he was at 1700 feet above sea level. How
many feet did Jake hike up the mountain?
Answer:1700
Step-by-step explanation:
In total, he traveled 1700 feet. He had to get to the 250ft starting point somehow, so you would count that as the overall total distance traveled.
What is Equivalent?
Is it possible for two things to look different but be equal
to one another? Think about $10... is a $10 bill the only
way you can have $10? Give an example of money that
is equivalent to a $10 bill.
Answer:
Equivalent is when two things contain the same total value. For example, you could give two 5 dollar bills instead of one 10 dollar bill and they would be equivalent as they would both total to be 10 dollars.
Step-by-step explanation:
$10 = 2 * x
$10/2 = $5
x = $5
find the distance between (-6,4) and (-2,1)
Answer:
[tex]d=2.65[/tex]
Step-by-step explanation:
Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}[/tex]
Simply plug in your 2 coordinates into the formula to find distance d:
[tex]d=\sqrt{(-2-(-6))^2-(1-4)^2}[/tex]
[tex]d=\sqrt{(-2+6))^2-(-3)^2}[/tex]
[tex]d=\sqrt{(4)^2-9}[/tex]
[tex]d=\sqrt{16-9}[/tex]
[tex]d=\sqrt{7}[/tex]
[tex]d=2.65[/tex]

Suppose S is between R and T. Use the Segment Addition Postulate to solve for the variable. Round to three decimal places. RS = 9y − 2 ST = y + 7 RT = 26
Answer:
The variable y = 2.100
Step-by-step explanation:
Here, we are told to solve for the variable y.
We are asked to use the segment addition postulate. In summary, the postulate is of the opinion that given 3 points X,Y and Z, we can only say that these 3 points are collinear(lie on the same line) if they obey the formula below;
XZ = XY + YZ
Now, we have that S is between R and T.
Mathematically that means;
RT = RS + ST
from the question, we are told that RT = 26, RS = 9y-2 and ST = y + 7
Now, insert these values into the alphabetical equation;
26 = (9y-2) + (y + 7)
26 = 9y-2 + y + 7
26 = 9y+y -2 + 7
26 = 10y + 5
26-5 = 10y
10y = 21
y = 21/10
y = 2.1
Which is y = 2.100 to three decimal places
