For which intervals is the function negative?Select each correct answer. (4,∞)(−1.5,4.2)(1,4)(−2.5,2.5)(−3,1)(−∞,−3)
Answers
Answer:
(−∞,−3)
(1,4)
Explanation:
To find the interval where the function is negative, we would look at the regions on the graph where the values of y are negative. The required intervals are the values of x in those regions. Looking at the graph,
On the left, the values of y are negative between x = - infinity and x = - 3
On the right, the values of y are negative between x = 1 and x = 4
Thus, the correct options are

Based on the data in question a, the graph for the data is skewed to the left. This can be graphed and seen visually but also by calculating the mean and the median of the data set. The mean of the data is 2.85 and the median is 3. Since the mean is less than the median, we can see that the data is negatively skewed, or skewed to the left.

How to find y-intercept of a graph?The y-intercept is the point where a graph crosses the y-axis.
In simple terms, it is the value of y when x = 0.
Therefore, the graph is express as follows:

Marsha buys 3 pounds of cheddar cheese and some Swiss cheese Both cheeses cost $450 per pound. The total cost is $24.75. How many pounds of Swiss cheese did Marsha buy?
Answers
Let x represent the number of pounds of Swiss cheese that Marsha bought.
We were told that Marsha buys 3 pounds of cheddar cheese and some Swiss cheese Both cheeses cost $450 per pound. This means that the cost of 3 pounds of cheddar cheese is 3 * 4.50 = 13.5
Also, the cost of x pounds of Swiss cheese is 4.5 * x = 4.5x
If the total cost is $24.75, it means that
4.5x + 13.5 = 24.75
The equation is
4.5x + 13.5 = 24.75
We would solve for x. Thus,
4.5x = 24.75 - 13.5
4.5x = 11.25
x = 11.25/4.5
x = 2.5
Thus, she bought 2.5 pounds of Swiss cheese
What is the degree of a polynomial?
Answers
Answer:
A polynomial's degree is the greatest power of a variable in a polynomial equation. The degree indicates the highest exponential power in the polynomial (ignoring the coefficients)
Step-by-step explanation:
The degree of a polynomial is the exponent of the leading term. For example, (x + 1) is a first-degree polynomial because x has an exponent of 1. (x^5 + 2y^4 - 3y^3 + y^2 - x + 3) is a fifth-degree polynomial because x has an exponent of 5.

The fractions arranged from greatest to least are- 13/15, 4/5, 7/9, 30/45
Here, we are given 4 fractions- 4/5, 2/3, 13/15, 7/9
In order to compare them, let us equalize their denominators.
The denominators are- 5, 3, 15 and 9
The LCM of 5, 3, 15 and 9 is 45
Thus, we can write the fractions as-
4/5 = (9*4)/(5*9) = 36/45
2/3 = (2*15)/(3*15) = 30/45
13/15 = (13*3)/(15*3) = 39/45
7/9 = (7*5)/(9*5) = 35/45
Now, we can easily compare the fractions by comparing their numerators.
We see that-
39 > 36 > 35 > 30
Thus, 13/15 > 4/5 > 7/9 > 30/45
Hence, the fractions arranged from greatest to least are- 13/15, 4/5, 7/9, 30/45

What function translates the function f(x) = to the right 2 units and up 10 units?
g(x)= |
Answers
Answer:
g(x) = | x - 2 | + 10
Step-by-step explanation:
given g(x) then g(x± h ) is a horizontal translation of g(x)
• if h > 0 then a move to the left of h units
• if h < 0 then a move to the right of h units
here the move is 2 units to the right, then
g(x) = | x - 2 |
given g(x) then g(x) + c is a vertical translation of g(x)
• if c > 0 then a move up
• if c < 0 then a move down
here the move is 10 units up , then
g(x) = | x - 2 | + 10

I need help with my scale project is there anyway you could make me two similar figures with this and it also has the proportions.
Answers
To make a similar figure, we measure the lengths of each component of the figure - for example, the leg of the figure is 2 units - and then multiply each measured length by a number. This number could be any number - could be 2, 3, 4 ... but we will choose a small enough number that will give us a figure that can fit inside the graph.
Now here are the measurements of the figure.
The legs = 1 units
bottom = 2 units
top = 2 units
sides = 2 units
nose = 0 units (it is a point)
eyes - 0.5 units
Now let's multiply the measurements above by 3, which gives
The legs = 3 units
bottom = 6 units
top = 6 units
sides = 6 units
nose = 0 units (it is a point)
eyes - 1.5 units.
