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

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.

Janice works part-time in a pizza restaurant. She makes a monthly salary of $240. She spends 3/5 of her salary on gas for her car. How much does Janice have left at the end of the month for her other expenses
Answer: 144
Step by step: In order to solve this easily, you should convert 3/5 into a decimal. In order to do that, you have to divide the numerator by the denominator. 3 divided by 5 = 0.6. Then you multiply 240 by 0.6 to get your answer, 144.

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]

Solve a = 2x + 6xz for X
Answer:
See Below.
Step-by-step explanation:
We are given the equation:

And we want to solve for x.
On the right-hand side, we can factor:
[tex]a=x(2+6z)[/tex]
And divide both sides by the factored expression. Hence:
[tex]\displaystyle x=\frac{a}{6z + 2}[/tex]
And we're done!

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.

___ 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
Zero pairs are two numbers that _____ to get zero. 1. add 2. subtract 3. divide 4. multiply

Area of triangle=42, the width is x+3 and the length is 2x+8, find the value of x
Step-by-step explanation:
Area of triangle = 1/2 × the width × the length
42 = 1/2(x+3)(2x+8)
42 = 1/2×2×(x+3)(x+4)
42 = (x+3)(x+4)
(x+3)(x+4) = 42
x² + 7x + 12 = 42
x² + 7x + 12 - 42 = 0
x² + 7x - 30 = 0
(x-3)(x+10) = 0
x = 3, -10
x can't be -10 because the width and the length should be only + values
x = 3
The value of x found by using the area of triangle concept is 3
What is the Area of a Triangle?
The entire area filled by a triangle's three sides on a two-dimensional plane is referred to as the triangle's area. The fundamental equation for a triangle's area is A = 1/2 b × h, where b and h are the product of the triangle's base and height. All triangle shapes, including scalene, isosceles, and equilateral triangles, may be calculated using this formula. It is important to keep in mind that a triangle's base and height are perpendicular to one another.
In the question, It is given that:
Area of triangle = 42.
Width of the triangle = x+3
Length of the triangle = 2x+8;
And, we know that:
Area of triangle = [tex]\frac{1}{2}[/tex]×[tex]lw[/tex]
⇒[tex]42[/tex] = [tex]\frac{1}{2}[/tex]×[tex](x+3)(2x+8)[/tex]
⇒42 = (x+3)(x+4)
⇒(x+3)(x+4) = 42
⇒x² + 7x + 12 = 42
⇒x² + 7x + 12 - 42 = 0
⇒x² + 7x - 30 = 0
⇒(x-3)(x+10) = 0
⇒x = 3, -10
x can't be -10 because the width and the length should be only + values
⇒x = 3
Hence, The value of x is 3.

Step-by-step explanation:
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.
