Explain two different ways to find a new value after an original value is increased by 30%.
Answers
Answer:
Frequently, we know the new amount and the percent change and need to know the original amount. We found that a $600 TV on sale for 30% off, cost $420 on sale. We might think, that to find the original cost of the TV that has a sale price of $420 after a sale of 30% off, we could just take 30% of the $420 cost and add it back to the $420 to find the original cost.
30% of $420 is 0.30($420) = $126 and $420 + $126 = $546.
Or, 130% of $420 is 1.3($420) = $546.
Notice that this is not the $600 original list price with which we started.

Which graph shows a function that is increasing at a constant rate?
Answers
Explanation: constant rate is where the line on the graph is constantly increasing.like shown in picture B.Where as in picture A it’s kinda all over the place
The graph showing a function increasing at a constant rate is graph B.
How to determine a increasing or decreasing function in an interval?In order to check the rate of rise of a function in an interval find the value of its derivative at all the points of that interval. If the values of derivatives are increasing then the function is increasing else it is decreasing.
The graphs A and B are given in the problem can be analysed one by one as follows,
Graph A,
In the interval [-∞,0], the slope of the function is decreasing.
And, in the interval [0,∞], the slope is increasing.
Thus, it is not increasing at a constant rate.
Graph B,
The function has the same slope in both the intervals [-∞,0] and [0,∞], which is positive.
It implies that the function is increasing at a constant rate.
Hence, the function shown in graph B is is increasing at a constant rate.

Answers
Answer:
Y Intercept = (0,8)
x Intercept = (-5,0)
Step-by-step explanation:
Rearrange to y=mx+c
-5y= -40-8x
-5y=-8x-40
Divide both sides by -5
y=8/5x+8
Y Intercept = (0,8)
X intercept; Find x when Y=0
0= 8/5x+8
8/5x = -8
x= -5
Hence;
X Intercept = (-5,0)

Answer:
1 pear costs 20 cents. 1 peach costs 10 cents.
Step-by-step explanation:
x represents pears
y represents peaches
4x + 2y = 1
2x + 3y = 0.7
multiply the second equation by -2 to elimate the x variable
(2x +3y = 0.7) -2 = -4x - 6y = -1.4
add the new equation to the first original one:
4x + 2y = 1
-4x - 6y = -1.4
-4y = -0.4. divide both sides by -4, y = 0.10
plug in y = 10, solve algebraically and get x = 0.20
Lastly, check your work:
4(0.20) + 2(0.10) = 1
2(0.20) + 3(0.10) = 0.7

Explain how to use the distributive property to simplify: -2(x + 5) ?
Answers
Answer:
-2x-10
Step-by-step explanation:
Distributive Property is basically a term for opening parentheses. So, in your case -2(x+5) we would multiply x and 5 by -2. X times -2 is -2x and 5 times negative 2 is -10. -2x-10 would be your final answer.
[tex]\huge\bold{ANSWER:}[/tex]
-2x-10
[tex]\bf{EXPLANATION:[/tex]
Hi there!
Here's what the Distributive Property states:
a(b+c)=ab+ac
So, we take a number outside the parentheses, and "distribute" it.
In this case, we should distribute -2:
-2(x+5)
-2x-10 (a negative times a negative is a positive)
Hope it helps!

What single percentage change is equivalent to a 18% increase followed by a 13% decrease?
Answers
Given:
18% increase followed by a 13% decrease.
To find:
The single percentage equivalent to a 18% increase followed by a 13% decrease.
Solution:
Let a number be 100.
If it is increased by 18% then the number becomes
[tex]Number=100+\dfrac{18}{100}\times 100[/tex]
[tex]=100+18[/tex]
[tex]=118[/tex]
Then, it is decreased by 13%.
[tex]Number=118-\dfrac{13}{100}\times 118[/tex]
[tex]=118-15.34[/tex]
[tex]=102.66[/tex]
New number is 102.66.
Now, the percentage change is
[tex]\%\text{ Change}=\dfrac{\text{New number - Initial number}}{\text{Initial number}}\times 100[/tex]
[tex]\%\text{ Change}=\dfrac{102.66-100}{100}\times 100[/tex]
[tex]\%\text{ Change}=\dfrac{2.66}{100}\times 100[/tex]
[tex]\%\text{ Change}=2.66\%[/tex]
Therefore, the Single percentage change is 2.66%.
