Answer:
Question 1: y = x + 4 if x>5
Question 2: y = x
Question 3: y = -x-4
Question 4: y = 3x-6
Step-by-step explanation:
Ok, I will admit, these questions are a bit confusing, but I will try my best.
Question 1: y = |x-3| + |x+2| - |x-5| if x>5. So, let's plug in a number greater than 5 - 6. y = |6-3| + |6+2| - |6-5|. Inside the absolute value, every number is positive, which pretty much renders the absolute value symbol useless. So, you can take the equation and change the absolute value lines into parentheses. y = (x-3) + (x+2) - (x-5). In order to get rid of the parentheses, you have to distribute any subtraction symbols which is in front of x-5. This makes our equation y = x - 3 + x + 2 -x + 5. Combine like terms to get y = x + 4 if x>5.
Question 2: y = |x-3| + |x+2| - |x-5| if -2<x<3. Let's plug in a number between -2 and 3 so 0. y = |0-3| + |0+2| - |0-5|. x-3 becomes a negative number, x+2 becomes a positive number, and x-5 becomes a negative number. Just like question 1, we can leave the x+2 alone since it's a positive number, but we have to change the x-3 and the x-5. So we'll take the equation and change the absolute value to parentheses, but for the values that are negative, we have to put a negative sign in front of to make it positive. Our equation looks like y = -(x-3) + (x+2) - -(x-5). Since there are two negatives in front of x-5, we can just make it a plus sign. We distribute the negative to x-3 to make our equation y = -x+3 + x+2 + x-5. Combine like terms to get y = x
Question 3: y = |x-3| + |x+2| - |x-5| if x<-2. Let's plug in -3 since it's less than -2. y = |-3-3| + |-3+2| - |-3-5|. All three parts of the function are negative numbers, so when we change it to parentheses, all parts will have a negative to distribute. Our equation looks like y = -(x-3) -(x+2) - -(x-5). Since there are two negatives in front of x-5, we can just make it a plus sign. We distribute the negative to x-3 and x+2 to make our equation y = -x+3 + -x-2 + x-5. Combine like terms to get y = -x-4.
Question 4: y = |x-3| + |x+2| - |x-5| if 3<x<5. Let's plug in 4 since it's in between 3 and 5. y = |4-3| + |4+2| - |4-5|. Only x-5 is negative so that's the only one we need to put a negative in front of when we change it to parentheses. Our equation looks like y = (x-3) + (x+2) - -(x-5). Since there are two negatives in front of x-5, we can just make it a plus sign. Our equation is now y = x-3 + x+2 + x-5. Combine like terms to get y = 3x-6.
Hope this helps! :)

TrueTrueThe diagram is shown below what happens when you dilate with a scale factor 2/3, and the center of dilation is D.
Line A'B' has the same slope of AB, so the lines are parallel.
Line AD and line A'D' are the same line, since D = D'. Recall that the center of dilation does not move when applying a dilation. Point A moves to A', which is one line AD. Due to D being at the center, all lines from the center will connect the four points shown.

However, Alex leaves the house 15 minutes earlier, drives 40mph, and arrives on time. How far from Alex's house is the appointment? need by sat.
Answers
Answer:
40 miles
Step-by-step explanation:
First, change the 15 minutes to 0.25 hours and 3 minutes to 0.05 because we are working with mph.
let x be the normal driving time to work in hours so 40x is the driving to work
since we know distance = speed multiplied by time we do
50(x-0.25+0.05)=40x
50(x-0.2)=40x
50x-10=40x
50x-40x=10
10x=10
x=1 hour normal time to work
therefore
40(1) = 40 mi to work
Confirm this by finding the dist when he went 50 mph for 48 min (0.8hrs)
50(1-.25+0.05) = 50(.8) = 40 mi also

Oatmeal is packaged in a right circular cylindrical container that has a radius of 2.5 inches and a height of 10 inches.
What is the surface area of this container in terms of π?
Answers
Answer:
surface area: 62.5π
explanation:
total surface area of cylinder: 2πr(h+r)
Given:
radius = 2.5 inchheight = 10 inchSolve:
2π(2.5)(10+2.5)
5π(12.5)
62.5π
Solution:
Given:
Radius of cylinder: 2.5 inHeight of cylinder: 10 inSurface area of cylinder: 2πrh + 2πr²
Using the formula:
[tex]2\pi rh + 2\pi r^{2} = \text{Surface area of cylinder}[/tex]
[tex]\rightarrow 2(3.14)(2.5)(10) + 2(3.14)(2.5)^{2} = \text{Surface area of cylinder}[/tex]
Simplifying the LHS:
[tex]\rightarrow (3.14)(50) + 2(3.14)(6.25) = \text{Surface area of cylinder}[/tex]
[tex]\rightarrow (31.4)(5) + (6.28)(6.25) = \text{Surface area of cylinder}[/tex]
[tex]\rightarrow \boxed{\bold{196.25 \ in^{2} = \text{Surface area of cylinder}}}[/tex]

Answers
Answer:
any point where x=3, 4, or 6.
Step-by-step explanation:
The thing that makes a function a function and not a relation is having only 1 y value per x value, which means if you draw a vertical line through a point, it should not intercept any other points. Basically, the main difference between a function and a relation is that a function can't have 2 points on top of each other.
Pick a point where x=3, 4, or 6. Those are the open spots on the grid with nothing above or below them. It doesn't matter which point you pick, as long as there is NOTHING directly above or below that point.
I hope you understood this solution. Happy mathing!

Answer:
[tex]n = 32[/tex]
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
~
First, add 10 to both sides of the equation:
[tex]\frac{n}{2} - 10 = 6\\\ \\\frac{n}{2}- 10 (+10) = 6 (+10)\\ \\\frac{n}{2} = 6 + 10\\\\\frac{n}{2} = 16[/tex]
Next, isolate the variable n by multiply 2 to both sides of the equation:
[tex]\frac{n}{2} = 16[/tex]
[tex]\frac{n}{2} *2 = 16 * 2[/tex]
[tex]n = 16 * 2\\n = 32[/tex]
[tex]n = 32[/tex] is your answer.

Step-by-step explanation:
Reason:
Frank drives 60miles per 1 hour ( 1:60)
If he drives 120miles, its per 2hours because you multiply by 2.
If he drives 360miles, its per 6 hours
Because 60x6=360 and 1x6=6 (6:360)
4,280 is odd one out because if he drives 4hours, you multiply 60 by 4 to get 240, 280 is incorrect
