Which relationship is a function?
Answer:
the first one
Step-by-step explanation:
remember, in a function, x can only have one y, whereas y can have more than one x
Answer:
The first one (the one with the months)
Step-by-step explanation:
A function is when an x value doesn't have more that one y value (y can have more than one x value, though). On the teachers and pets one, Ms. Valverde has two pets, so that doesn't count. On the shapes one, the orange square is pointing to another orange square and a triangle, so that doesn't count. The last one has 7 equaling to 12 and 13, so that doesn't count. The one with the months doesn't have any x values with more than one y value, so it is a function.
Rectangle N NN has an area of 5 55 square units. James drew a scaled version of Rectangle N NN and labeled it Rectangle P PP. Rectangle P Rectangle P What scale factor did James use to go from Rectangle N NN to Rectangle P PP?
Answer:
The scaled factor is 3.
Step-by-step explanation:
Consider the figure shown below:
It is given that: A rectangle N has an area of 5 square units. James drew a scaled version of Rectangle N and labeled it Rectangle P.
We need to find the scale factor which is used by James.
First, we will calculate the area of Rectangle P by counting the number of squares shown in the figure.
Area of rectangle P = 45 square unit
Let x be the scaled factor.
To scale the rectangle we need to multiply both the length and breadth of the rectangle N by x and the scaled area should be equal to 45.
[tex][x\times \text{Length} ][x \times \text{breadth}]=45[/tex]
[tex]x^2(\text{Length} \times \text{breadth})=45[/tex]
It is given that area of the rectangle N is 5 square units, so put length time breadth as 5.
[tex]x^2(5)=45[/tex]
[tex]x^2=9[/tex]
[tex]x=3[/tex]
Hence, the scaled factor is 3.

Quante’ had 15.3 feet of fishing line. He cut off a piece and had 3.2 inches left. How long was the piece he cut off?
Answer:
180.4 inches (15.033 feet)
Step-by-step explanation:
To solve this, we convert 15.3 feet to inches. We do this by multiplying 15.3 by 12. This gets us 183.6. Now, we subtract 3.2 from 183.6. This gets us 180.4. That means the piece cut off of 180.4 inches long. To convert this to feet, we divide by 12. That gets us 15.033. That means the piece cut off is 180.4 inches long, or 15.033 feet long.
some soiled goods are sold for 2 /5 of their original price. what will be the selling price of a pair of trouser originally Costing#850.00
Answer:
The selling price of the goods is #340.00
Step-by-step explanation:
Given;
original price, P = #850.00
the new cost = 2/ 5 of the original price
The selling price of the goods is calculated as follows;
[tex]= \frac{2}{5} \ \times \#850\\\\ = \# 340[/tex]
Therefore, the selling price of the goods is #340.00

Answer:
x = 2; y = 6
Step-by-step explanation:
y=3x
x+y=8 [substitute y for 3x]
x+3x=8; 4x=8; x=2
if x=2, y=3x or y=3(2) = 6
Solve for k in the equation 12 = 4(k - 6)
Answer:
12 = 4 (k - 6) (use the distributive property to get rid of the parentheses)
12 = 4k -24 (add 24 to both sides to isolate the k-term)
36 = 4k (divide both sides by 4 to get k all alone)
k = 9 (your answer)

Determine which representation corresponds to a decreasing speed with an increasing time. A 2-column table with 5 rows. The first column is labeled time with entries 0, 2, 4, 6, 8. The second column is labeled speed with entries 0, 15, 25, 45, 70. A graph shows time (seconds) labeled 1 to 8 on the horizontal axis and speed (feet per second) on the vertical axis labeled 1 to 8. A line shows the speed starting at 7 feet per second and continuing to lose speed over 5 seconds.
Answer:it c
Step-by-step explanation:
The Graph representation corresponds to a decreasing speed with an increasing time.
What is Graph?In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way. The relationships between two or more items are frequently represented by the points on a graph.
Given:
We have the table
Time Speed
0 0
2 15
4 25
6 45
8 70
So, the rate of change
= (15-0) / (2-0)
= 15/2
= 7.5
and, the rate of change
= (25-15) / (4-2)
= 10/2
= 5
and, the rate of change
= (45-25) / (6-4)
= 20/2
= 10
and, the rate of change
= (70-45) / (8-6)
= 25/2
= 12.5
As, the rate of change is increasing.
and, from the graph the slope is decreasing as time increases.

There are five sign changes, so there are five or, counting down in pairs, three or one negative solutions. Then my answer is:There are two or zero positive solutions, and five, three, or one negative solutions.In the above example, the maximum number of positive solutions (two) and the maximum number of negative solutions (five) added up to the leading degree (seven). It will always be true that the sum of the possible numbers of positive and negative solutions will be equal to the degree of the polynomial, or two less, or four less, or....This can be helpful for checking your work. For instance, if I had come up with a maximum answer of "two" for the possible positive solutions in the above example but had come up with only, say, "four" for the possible negative solutions, then I would have known that I had made a mistake somewhere, because 2 + 4 does not equal 7, or 5, or 3, or 1
There are four, two, or zero positive roots, and zero negative roots.
Descartes' Rule of Signs can be useful for helping you figure out (if you don't have a graphing calculator that can show you) where to look for the zeroes of a polynomial. For instance, suppose the Rational Roots Test gives you a long list of potential zeroes, you've found one negative zero, and the Rule of Signs says that there is at most one negative root. Then you know that you've found every possible negative root (rational or otherwise), so you should now start looking at potential positive roots.Similarly, if you've found, say, two positive solutions, and the Rule of Signs says that you should have, say, five or three or one positive solutions, then you know that, since you've found two, there is at least one more (to take you up to three), and maybe three more (to take you up to five), so you should keep looking for a positive solution.
