BRAINLIEST ASAP! PLEASE. HELP ME :) I need help with part 2 of the question.
Part 2:
-4a + 2 + 11a = 5a + 3 + 2a
~Combine like terms
7a + 2 = 7a + 3
~Subtract 2 to both sides
7a = 7a - 1
~Subtract 7a to both sides
0 = 1
Therefore, there are no solutions.

___ power of 10 gives the answer 1,000,000,000? * 10 9 11 6
Answer:
9
Step-by-step explanation:
We see that we have 9 zeros.
We use the base 10 system to help us solve.
When we multiply anything by 10, we simply move the decimal place to the right.
Since we have 9 zeros, we move the decimal place 9 places to the right. Therefore, to get 1,000,000,000, we multiply 1 by 10⁹
solve for x
3+x/8=4
Answer:
x = 8
Step-by-step explanation:
3+x/8=4
We move all terms to the left:
3+x/8-(4)=0
We add all the numbers together, and all the variables
x/8-1=0
We multiply all the terms by the denominator
x-1*8=0
We add all the numbers together, and all the variables
x-8=0
We move all terms containing x to the left, all other terms to the right
x=8

Which is the definition of a ray?
a part of a line that has one endpoint and extends indefinitely in one direction
the set of all points in a plane that are a given distance away from a given point
lines that lie in the same plane and do not intersect
a part of a line that has two endpoints
The definition of a ray is a part of a line that has one endpoint and extends indefinitely in one direction
A ray is part of a line that has one endpoint and extends indefinitely in one direction and has the folowing properties.
It has one starting point called its endpoint. It does not have height or width but has length. But, its length is not measurable since it extends forever.So, the definition of a ray is a part of a line that has one endpoint and extends indefinitely in one direction.

Find the sum 32 +33 +34 + 35 + ... + 112 + 113.
Answer:
5945
Step-by-step explanation:
The sum for an arithmetic series is given by the formula:
[tex]S=(x_1+x_k)\cdot\frac{k}{2}[/tex]
Where x₁ is the initial term, x_k is the last term, and k is the number of elements in the series.
From the sequence, we can see that the first term is 32. The last term is 113.
To determine how many elements we have, subtract 113 and 32:
[tex]113-32=81[/tex]
However, we must add 1 to this number since this doesn't include the first term. Thus:
[tex]81+1=82[/tex]
So, there are 82 terms in total.
Therefore, our sum is:
[tex]S=(32+113)\cdot\frac{82}{2}[/tex]
[tex]S=(145)\cdot 41=5945[/tex]
Answer:
5945
Step-by-step explanation:
an = a1 + ( n - 1) 1
a1 = first term
n = number of terms
an = last term
113 = 32 + ( n - 1 ) 1
113 = 32 + n -1
113 = 31 + n
n = 113 - 31
n = 82.
Sn = n/2(a1 + an)
S82 = 82/2 (32 + 113)
S82 = 41 (145)
S82 = 5945.
x2 – 25 = - 4x – 4
Solve the quadratic by factoring
Answer:
x = -7, +3
Step-by-step explanation:
x² - 25 = -4x - 4
Put it all on one side
x² - 25 + 4x + 4 = 0
Put like terms together
x² + 4x - 21 = 0
Factor
(x + 7)(x - 3) = 0
x + 7 = 0 ⇒ x = -7
x - 3 = 0 ⇒ x = +3
x = -7, +3

College precalc! If you could help me with range, too, that's be great.
Answer:
All together:
D:(-∞,∞)
R:(-∞,2]
Individually:
D: (-∞,-2], (-2,∞)
R: (-∞,-2], y=2
Step-by-step explanation:
So the way I like to think about Domain and Range is that the Domain is the set of real numbers which can be put into a function and the Range is the set of real numbers which you can get out from a function.
Looking at your given function, it looks like the piece-wise parts are f(x)=x and f(x)=2. Neither one of the functions has domain restrictions (you can plug anything into the first and second without getting any mathematical errors [like a 0 in the denominator]). And since the graph shows arrows in each end, indicating infinite continuation of the curve, the Domain is (-∞,∞).
Now for the outputs of each function, we can see that you'll be getting any number out for the f(x)=x portion. But, the f(x)=2 portion will always give you 2 for any input. So the Range is (-∞,2).
Now I'm honestly not too sure what the HW is asking you to do with this info... for the first part, maybe they want the individual domain and range values for each piece of the piece-wise while the second part asks for the overall? You might know what it's asking better then me since it's your class.
I'll include the overall and individual answers above. Comment with any questions.

Step-by-step explanation:
A quantity P obeys the exponential growth law P(t)=e5t (t in years).
At what time t0 is P=15? Use yr for years. t0=?
At what time t1 is P=20? Use yr for years. t1= ?
What is the doubling time for P? Use yr for years. The doubling time is ?
Answer:
the time at which P =15 is [tex]{t_o = 0.54161 \ years}[/tex]
the time at which P =20 is [tex]{t_1 = 0.59914 \ years}[/tex]
the doubling time [tex]{t = 0.138629 \ years}[/tex]
Step-by-step explanation:
From the information we are being provided with:
The quantity P i.e [tex]P(t) = e ^{5t}[/tex]
In order to determine the time at which P = 15, we have the following:
[tex]t= t_o[/tex] when P = 15
∴ [tex]e^{5t_o} = 15[/tex]
[tex]5t_o= In (15)[/tex]
[tex]t_o = \dfrac{1}{5}In 15[/tex]
[tex]t_o = \dfrac{1}{5} \times 2.70805[/tex]
[tex]{t_o = 0.54161 \ years}[/tex]
Hence, the time at which P =15 is [tex]{t_o = 0.54161 \ years}[/tex]
In order to determine the time at which P = 20, we have the following:
[tex]t= t_1[/tex] when P = 20
∴ [tex]e^{5t_1} = 20[/tex]
[tex]5t_1= In (20)[/tex]
[tex]t_1= \dfrac{1}{5}In (20)[/tex]
[tex]t_1 = \dfrac{1}{5} \times 2.9957[/tex]
[tex]{t_1 = 0.59914 \ years}[/tex]
Hence, the time at which P =20 is [tex]{t_1 = 0.59914 \ years}[/tex]
The doubling time at t = 0, mean P = 2
∴ [tex]e^{5t} = 2[/tex]
[tex]5t= In (2)[/tex]
[tex]t= \dfrac{1}{5}In(2)[/tex]
[tex]t = \dfrac{1}{5} \times0.693147[/tex]
[tex]{t = 0.138629 \ years}[/tex]
Hence, the doubling time [tex]{t = 0.138629 \ years}[/tex]

12 - d > 8. Solving inequalities
Answer:
d<4 I might not be right but I think this is correct
Step-by-step explanation:
Simplify both sides of the inequality.
−d+12>8
Subtract 12 from both sides.
−d+12−12>8−12
−d>−4
Divide both sides by -1.

Suppose the average yearly salary of an individual whose final degree is a master's is $41 thousand less than twice that of an individual whose final degree is a bachelor's. Combined, two people with each of these educational attainments earn $115 thousand. Find the average yearly salary of an individual with each of these final degrees.
Answer:N/B The amount is in thousands
The total amount earned by a Bachelor's person be $x:
amount earned by a masters person will be $(2x-38)
Total amount earned by the two individuals will be:
x+(2x-38)=115
solving for x we get:
x+2x-38=115
3x=115+38
3x=153
x=153/3
x=51
also:
2x-38=2*51-38=64
therefore we conclude that master's individual earns average of $ 64,000 while the Bachelor's individual earns $51,000.

Water flows through a pipe at a rate of 91 fluid ounces every 2.5 weeks. Express this rate of flow in cups per hour.
Answer:
[tex]Rate = 0.2167\ fl\ oz/hour[/tex]
Step-by-step explanation:
Given
[tex]Rate = \frac{91\ fl\ oz}{2.5\ weeks}[/tex]
Required
Express the rate as per hour
[tex]Rate = \frac{91\ fl\ oz}{2.5\ weeks}[/tex]
There are 168 hours in a week;
So, the rate becomes
[tex]Rate = \frac{91\ fl\ oz}{2.5 * 168\ hours}[/tex]
[tex]Rate = \frac{91\ fl\ oz}{420\ hours}[/tex]
[tex]Rate = 0.2167\ fl\ oz/hour[/tex]
Hence;
The equivalent of the given rate is [tex]0.2167\ fl\ oz/hour[/tex]
