Step-by-step explanation:
first u have to put the like terms together which are 7p and 19p when u move the 19p th 7p it turns to minus su have to minus 7p-19p which equals to -12 check if there is more like terms there arent so u have to keep the rest the sameAnswer:
B. (5q - 12) / 12
Step-by-step explanation:
7p + 5q = 19p + 12
So, we are looking for p, let's move all the p on the left, and the rest on the right
7p + 5q = 19p + 12
7p - 19p = 12 - 5q
-12p = 12 - 5q
Now to get single p we need to divide both sides by -12
-12p = 12 - 5q
p = [tex]\frac{12 - 5q}{-12}[/tex]
We don't have answer like this, so we have to get rid of the minus from this equation. To do so, we have to multiply the fraction's top and bottom by (-1)
[tex]\frac{12 - 5q}{-12} * \frac{-1}{-1} = \frac{- 12 + 5q}{12}[/tex]
all right, we almost got it, now let's change the order in top of the fraction:
p = [tex]\frac{- 12 + 5q}{12}[/tex]
p = [tex]\frac{5q - 12}{12}[/tex]
And it's done

Answers
Answer:
6.4 ounces
Step-by-step explanation:
The total number of 'parts' is 5 containing 2 parts yellow and 3 parts green so if we divide 16 ounces of blue paint by the 5 parts, we can find 1 part. 1 part is 3.2. Yellow uses 2 parts so we time 3.2 by 2. The answer should be 6.4

Given the functions,
f(x) = x^3 - 4x^2 + 5
g(x) = x^2 + 6x - 7
h(x) = x + 6
Find f(g(-3)).
Answers
Answer:
f(g(- 3) ) = - 5115
Step-by-step explanation:
Evaluate g(- 3) then substitute the value obtained into f(x)
g(- 3) = (- 3)² + 6(- 3) - 7 = 9 - 18 - 7 = - 16 , then
f(- 16) = (- 16)³ - 4(- 16)² + 5
= - 4096 - 4(256) + 5
= - 4096 - 1024 + 5
= - 5115
The price of a scarf is reduced by $2.19. The price is now $8.40. What was the original price of the scarf? Enter your answer in the box. $WHOEVER ANSWER GETS BRAINLESS NEED HELP
Answers
If the price was reduced by $2.19, the original price of the scarf would be $2.19 + $8.40 which is $10.59
Answer:
The original price of the scarf was $10.59.
Step-by-step explanation:
"The price of a scarf is reduced by 2.19. The price is now 8.40."
Let X be the original price of the scarf.
That can be written as an equation like this:
x - 2.19 = 8.40
Now, just solve for x. Add 2.19 to both sides:
x = 10.59
The original price of the scarf was $10.59.

ANALYZE The table below shows the values of a cubic function. Could there be a zero between
x= 2 and x = 3? Justify your argument.
ONLY QUESTION 30
Answers
Answer:
No; no sign change of g(x) in that interval
Step-by-step explanation:
The intermediate value theorem tells you there will be at least one zero between any two points where the function changes sign. The table shows sign changes in the intervals [-2, -1], [0, 1], and [1, 2]. So, the three zeros of the cubic lie in those intervals.
There are no additional zeros to be found, and there are no sign changes of g(x) between x=2 and x=3, so there is no zero in the interval [2, 3].
_____
Additional comments
We can only answer this with certainty because we have already found the locations of the three real zeros this cubic has. If there were two that were unaccounted for, then the possibility might exist for the graph to make an excursion across the x-axis and back in the interval [2, 3].
__
First differences of the table values are ...
-5, +1, +2, -3, 0
Second differences are ...
6, 1, -5, 3
Third differences are ...
-5, -6, +8
This table cannot represent a real cubic function. For evenly-spaced x-values, a cubic polynomial must have constant 3rd differences. If the last two values in the table were -1 and -12, the function would be ...
g(x) = -5/6x^3 +1/2x^2 +7/3x -1

6.2 Margin of error and the confidence interval. A study of stress on the campus of your university using the College Undergraduate Stress Scale (CUSS) reported an average stress level of 1123 (a higher score indicating more stress) with a margin of error of 43 for 95% confidence. The study was based on a random sample of 400 undergraduates. a. Give the 95% confidence interval. b. If you wanted 99% confidence for the same study, would your margin of error be greater than, equal to, or less than 43
Answers
Using confidence interval concepts, it is found that:
a. The 95% confidence interval is (1080, 1166).
b. The margin of error would be greater than 43.
Item a:
The interval is the sample mean plus/minus the margin of error, hence:
[tex]1123 - 43 = 1080[/tex]
[tex]1123 + 43 = 1166[/tex]
The 95% confidence interval is (1080, 1166).
Item b:
The margin of error is direct proportional to the critical value.The higher the confidence level, the higher the critical value, and thus, the higher the margin of error.Hence: The margin of error would be greater than 43.
