Answer:
-2(4-1)
Step-by-step explanation:
Do parentheses first because of PEMDAS. That means 4-1 equals 3. Then take -2 and times it by the 3 to get -6.
Answer:
The answer would be -2(4-1)
Step-by-step explanation:
-2 multiplied by 4 is -8
-2 multiplied by -1 is 2

Answers:
6) B. Negative7) A. Positive==============================================
Explanation:
x < 0 means x is negative
y > 0 tells us y is positive
Dividing a positive by a negative, or vice versa, means the result is negative. It's similar to how positive times negative = negative. So that is why the answer to problem 6 is "negative".
---------------
In problem 7, we square x to get some positive result.
Consider something like x = -7. Squaring this leads to
x^2 = (-7)^2 = (-7)*(-7) = 49
The two negatives cancel out when we square.
Since x^2 is positive, and y is positive, this means x^2*y is positive as well.

All three functions share the same range.

Answers
Answer:
The statements that can be used to compare the characteristics of the functions are:
1. g(x) has the greatest maximum value.
2. All three functions share the same domain.
Explanation:
- The table shows the values of three functions - f(x), g(x), and h(x) - evaluated at different values of x.
- We cannot determine the domain of f(x) or h(x) from the given table but we can see that g(x) has a domain of all real numbers.
- We can see that g(x) has the highest maximum value among the three functions, which is 8.
- We cannot determine the range of f(x) or g(x) from the given table but we can see that h(x) has a range of all negative numbers.
- We cannot say anything about the domain or range of f(x) based on the given table.
- Therefore, the two statements that can be used to compare the characteristics of the functions are: g(x) has the greatest maximum value and all three functions share the same domain.

Given:
Quadrilateral A has side lengths 6,9,9, and 12.
Quadrlateral B with its shortest side length 2.
Required:
(a)Scale factor.
(b)Perimeter of qaudrilateral B.
Explanation:
We have the quadrilateral A with its side lengths 6,9,9, and 12.
Also, the shortest length of side of quadrilateral B is 2.
(a) The scale factor can be calculated by dividing the shortest length of side quadrilateral A by the shortest length of side of quadrilateral B.
Therefore, scale factor is,
\(\frac{6}{2}=3\)Hence, the lengths of sides of quadrilateral B are, 2,3,3, and 4.
(b) The perimeter (P) of quadrilateral B is the sum of lengths of all its sides given by,
\(\begin{gathered} P=2+3+3+4 \\ \Rightarrow P=12 \end{gathered}\)Final Answer:
(a)The scale factor is, 3.
(b)The perimeter of quadrilateral B is 12.

x = 2
f(2) = 10 - 10 = 0

Y varies inversley with x. If y = -2 when x = 6, find the value of y when x = -12.
Answers
The value of y for the inverse variation when x = -12 is derived to be equal to 1.
What is inverse variationInverse variation is a mathematical relationship between two variables, in which an increase in one variable leads to a proportional decrease in the other variable. Mathematically, inverse variation can be expressed as y = k/x, where y and x are the two variables, k is a constant of proportionality, and the product of y and x is always equal to k.
when x = 6 and y = -2, then k is derived as:
-2 = k/6
k = -12 {cross multiplication}
when x = -12, y is derived as:
y = -12/-12
y = 1
Therefore, the value of y for the inverse variation when x = -12 is derived to be equal to 1.

A small tier will serve guests and a large tier will serve guests.
Answers
Answer:
small tier: 22large tier: 50Step-by-step explanation:
If cakes of 4 small and 4 large tiers serve 288 guests, and 3 small and 5 large tiers serve 316 guests, you want to know the number of guests served by a tier of each size.
SetupLet 's' and 'l' represent the numbers of guests served by small and large cake tiers, respectively. The first cake serves ...
4s +4l = 288
And the second cake serves ...
3s +5l = 316
SolutionSubtracting 3/4 of the first equation from the second gives ...
(3x +5l) -3/4(4s +4l) = (316) -3/4(288)
2l = 100
l = 50
4s +4(50) = 288 . . . substitute for l in the first equation
4s = 88 . . . . . . . . . . subtract 200
s = 22 . . . . . . . divide by 4
A small tier will serve 22 guests; a large tier will serve 50 guests.

Answers
Answer:
x = 9
Step-by-step explanation:
To solve the equation 2x - 7 + 3x = 4x + 2 for x, you can follow these steps:
Combine like terms on both sides of the equation. Add the x terms together and move the constant terms to one side of the equation:
2x + 3x - 4x = 2 + 7
Simplifying the left side: x = 9
Simplify the right side of the equation:
x = 9
Therefore, the solution to the equation is x = 9.

A study on college students found that the men had an average weight of about 66 kg and an SD of about 9 kg. The women had an average weight of about 55 kg and an SD of 9 kg.
Roughly what percentage of the men weighed between 57 kg and 75 kg?
Need help ASAP!
Answers
The percentage of the men that weighed between 57 kg and 75 kg is 68%.
What percentage of the men?The percentage of the men that weighed between 57 kg and 75 kg is calculated by applying normal distribution formula.
In a standard normal distribution curve, we have the following;
One standard deviation below the mean = M - S.D = 34%
One standard deviation above the mean = M + S.D = 34%
The number of men that would weigh 57kg is calculated as;
M - S.D = 66 - 9
M - S.D = 57
The number of men that would weigh 75kg is calculated as;
M + S.D = 66 + 9
M + S.D = 75
So we can see that 57 and 75 lie between one standard deviation below the mean and one standard deviation above the mean.
The total probability = 34% + 34% = 68%
