1) Convert the following to decimals:
a) 25% b) 60% c) 72.1%
d) 7%
e) 9.5%
f).66%
25% = 25% : 100% = 0,25 ← the end
60% = 60% : 100% = 0,6 ← the end
72,1% = 72,1% : 100% = 0,721 ← the end
7% = 7% : 100% = 0,07 ← the end
9,5% = 9,5% : 100% = 0,095 ← the end
66% = 66% : 100% = 0,66

Can someone please help me? I just need these question for finish my test.
Answer:
A. y = |x - 5| - 4
Step-by-step explanation:
The shape of the graph is a V with slope 1 on the right side and slope -1 on the left side. The parent function is y = |x|. The vertex of the V in the parent function is at (0, 0). Here, there has been a translation of the vertex to (5, -4).
The x-coordinate shifted 5 units right, or a shift of +5, and the y-coordinate shifted 4 units down, or a shift of -4.
y - k = |x - h| shows a shift of h units in x and k units in y when compared to the parent function y = |x|.
y - (-4) = |x - 5|
y + 4 = |x - 5|
y = |x - 5| - 4
Answer: A. y = |x - 5| - 4

You take a package to your local shipping company. They charge a fixed base cost of 6 per package plus an additional 0.39 per pound If p represents the number of pounds and c is the total cost of shipping your package write the linear equation that represents the relationship between pans c
Answer:
c = 6 + 0.39p or c = 0.39p + 6
Step-by-step explanation:
p = #pounds
c = total cost to ship
cost c = $6 + $0.39p ($6 flat fee + $0.39 per pound)
Answer:
C=0.39P+6
Step-by-step explanation:
0.39 is per pound, 6 is the fixed charge

let's write the given equation in its slope intercept form :
i.e y = 6x + 8
by comparing to the general equation : y = mx + c
we get, slope (m) = 6
what is the slop of 2x+3y-9=0
Answer:
Step-by-step explanation:
We need to write this equation in y=mx+b where m is the slope.
3y= -2x +9
y= -2/3 +9
So now that it is in the form of y=mx+b, we can find the slope. -2/3 is the slope of the equation. Hope that helps!
Can somebody tell me the domain and show me or tell me the work plz.
Answer:
Set the denom to 0 and solve.
x^2 - 16 = 0 --> x = -4,4
This means the vertical asymptote is 4, -4.
Therefor, the domain is for all real numbers that are not 4, -4.
We ignore the top because if the numerator was 0, it's still a number. But if the denom was 0, then it would be impossible (you can't divide by 0). So for all numbers that can go into the denom that aren't 0, is your domain.

What is mean median mode range?
Answer:
Mean- the average of data, meaning you add up all the numbers, and then divide the sum of the numbers by how many numbers there are. For example:
2, 2, 3, 4, 6, 6, 9.
7 numbers total.
2 + 2 + 3 + 4 + 6 + 6 + 9 = 32
32 ÷ 7 = 4.57
The mean would be 4.57.
Median- the middle point of the numbers. You cross off each of the numbers until you have one last number standing. If you have an even number of numbers, you find the middle of the last two numbers you crossed off. For example:
2, 2, 3, 4, 6, 6, 9
2, 3, 4, 6, 6
3, 4, 6
4
4 would be the median.
Mode- the largest number on the data.
Range- subtract the mode (largest number) from the smallest number to get range. For example:
2, 2, 3, 4, 6, 6, 9
9 - 2 = 7
7 would be the range.
Step-by-step explanation:
Let A = {a, b, c, d}, B = {a, c, d, e}. Let f : A → R and g : B → R such that f = {(a, 1),(b, 2),(c, 2),(d, 4)} and g = {(a, 0),(c, 4),(d, 8),(e, 0)}. State the domain and find: f − g

hi <3
multiply the coefficient of x^2 with the last value:
2 x 3 = 6
you need to find a value that multiplies to give 6 and adds to give 5
this would be 3 and 2
now you have:
(x + 3)(x + 2)
we need to incorporate the 2 into it
you can divide the 2 by 2 so that part is fine. however, as 3 cant be divided by 2, you have to carry the 2 up as a coefficient for x
your final answer works out to be:
(2x + 3)(x + 1)
hope this helps :)
