Hope I was able to satisfy your needs
First you make the fractions have a common denominator. In this case it would be 6.
Then you have 8 3/6 - 2 4/6.
Because the number you are subtracting is greater than what you are subtracting from, you can turn the fraction into an improper fraction.
8 3/6 = 7 9/6
9/6 - 4/6 = 5/6
Then subtract the whole numbers.

How much money would Julie earn for working 16 hours?
Julie works 1/12 hours/dollars. Write one or two-sentence explanation of what this rate means use this rate to find how long it takes for Julie to earn $228
Julie would earn $12/h×16h=$192
This rate means that for each hour she works, she gets $12.
The general formula for calculating these types of problems is:
m = r × t,
where m marks the total amount of money, r marks the rate and t marks the time.
To find the time when
m = $228
r = $12/h,
t = m ÷ t = 228 ÷ 12 = 19 hours.

The vertex form of the equation of
a parabola is y = 2(x +4^2 - 7.What is the standard form of the equation?
Answer:
The standard form of the equation is y = 2x^2 + 16x + 25
Step-by-step explanation:
To find the standard form, first square the parenthesis.
y = 2(x + 4)^2 - 7
y = 2(x^2 + -8x + 16) - 7
Now distribute the 2
y = 2(x^2 + 8x + 16) - 7
y = 2x^2 + 16x + 32 - 7
Now combine like terms
y = 2x^2 + 16x + 32 - 7
y = 2x^2 + 16x + 25
Answer:
y = 2x^2 + 16x + 25

Sqrt63, sqrt65 sqry67 sqrt69?
slope intercept equation for (0,-4) and (4,1)
Answer:
y = (5/4)x - 4
Step-by-step explanation:
As we move from (0, -4) to (4, 1), x increases by 4 and y increases by 5.
Thus, the slope of the line segment connecting these two points is
m = rise / run = 5/4.
Subbing these knowns into the point-slope formula for the equation of a straight line, we get:
y - 1 = (5/4)(x - 4), or
y = (5/4)x - 5 + 1, or
y = (5/4)x - 4
Let's check this out. Determine whether or not (0, -4) satisfies the equation:
-4 = (5/4)(0) - 4
Yes, this is true; the equation is correct.
How far will a freight train travel in 3 hours at an average speed of 48 miles per hour?
Answer:
48 X 3= 144 miles
Step-by-step explanation:
Answer:
144 miles
Step-by-step explanation:
First, let's use the distance formula which is distance = rate*time.
We know the rate is 48 miles and the time is 3 hours so if you were to plug it in to the formula you'd get distance = 48*3.
When you multiply 48 by 3 you get 144 which will be the distance.

c. x > 0
d. All real number
ASAP !!!!
Answer:
C. [tex]x>0[/tex]
Step-by-step explanation:
Given: [tex]f(x)=log(8x)[/tex]
To find the domain of a logarithmic function, we need to take the argument, 8x, and set it greater to zero. This is because an argument of a logarithmic function cannot be zero or negative.
[tex]8x>0[/tex]
[tex]x>0[/tex]
So since x is greater than zero, we have just found out our domain:
Interval Notation: (0, ∞)
Set Notation: {[tex]x|x>0[/tex]}
The domain of the logarithmic function is,

Step-by-step explanation:
Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.
A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:
[tex]\frac{BC}{EF} =\frac{AC}{DF}[/tex].
[tex]\frac{18}{x}=\frac{12}{10}[/tex]
To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
[tex]\frac{18}{x}=\frac{12}{10}\\ 18*10 = x*12 \\ 180 = 12x \\ 15 = x[/tex]

Simplify the expression given below x^2+x-2/x^3-x^2+2x-2
Answer:
The simplest form is [tex]\frac{x+2}{x^2+2}[/tex]
Explanation:
The given is: [tex]\frac{x^2 + x-2}{x^3-x^2+2x+2}[/tex]
1- For the numerator:
[tex]x^2+x-2[/tex] can be factorized to give (x-1)(x+2)
2- For the denominator:
[tex]x^3-x^2+2x-2[/tex]
We will factor this using grouping
Take [tex]x^2[/tex] as a common factor from the first two terms and [tex]2[/tex] as a common factor from the last two terms
This will give us:
[tex]x^3-x^2+2x-2[/tex] [tex]=x^2(x-1) + 2(x-1)[/tex]
Now, take (x-1) as a common factor:
[tex]x^3-x^2+2x-2[/tex] = (x-1)(x²+2)
3- Finally, getting the simplest form:
[tex]\frac{x^2+x-2}{x^3-x^2+2x-2}=\frac{(x-1)(x+2)}{(x-1)(x^2+2)}=\frac{x+2}{x^2+2}[/tex]
