What is the slope of the line through (-1, -7) and (3,9)?
Answers
Answer:
B (4)
Step-by-step explanation:
[tex]\frac{9+7}{3+1}[/tex] = [tex]\frac{16}{4}[/tex] = [tex]\frac{4}{1}[/tex] = 4
This is because you use the formula
Y2-y1
———-
X2-x1
So you would take Y2 which = 9 then subtract y1 which is -7 This equals 16
Then you take x2 which is 3 and subtract -1 which equals 4
Then you take 16/4 which equals 4

Answer:
29.25
Step-by-step explanation:
This is a simple function table we are working with, so we see that 2 (pounds) would cost around $4.50. So Next we look at 4 would equal $9. By doing this I divide 9 by 4 to get the answer of 2.25. This is are new function table rule of C=P x 2.25. Now that we have this we know that 13 is are P (pounds) and we are looking for are C (cost) After we input 13 into are function rule. We get the answer of $29.25.
Answer: well 14 pounds cost $31.50
so that means 13 pounds cost $29.50

Answer:
five sixths pound
Step-by-step explanation:
Kip bought [tex]1\frac{4}{6}[/tex] pounds of toffee. He gave [tex]\frac{5}{6}[/tex] of a pound to his friend. How much toffee does he have left?
The narrator is asking how much he has left after giving some toffee to his friend, that means we have to subtract.
[tex]1\frac{4}{6}[/tex] - [tex]\frac{5}{6}[/tex]
We already have an equal denominator so we can just subtract.
[tex]\frac{10}{6}-\frac{5}{6}[/tex] = [tex]\frac{5}{6}[/tex]
Kip has [tex]\frac{5}{6}[/tex] pounds left.

The tail of a kite is 1.5 feet plus twice the length of the kite. Together, the kite and tail are 15.5 ft long. Find the length of the tail.
What is the length of the tail? Show your work.
Answers
Answer:
We know that the kite with the tail is 15 feet and 6 inches. While 6 inches is 0,50 foot, it's 15,5 feet. If the lenght of the kite is x, then:
15,5 = x + 1,5 + 2x
15,5 = 3x + 1,5 / - 1,5 (both sides)
14 = 3x / : 3 (both sides)
x ≈ 4,66
The kite is approx .4,66 feet long. It means that the tail is about 15,5 - 4,66 = 10,84 feet long.
Answer:
10 5/6 feet
Step-by-step explanation:
Tail= 1.5+2Kite
Kite+Tail=15.5
x+1.5+2x=15.5
3x=15.5-1.5
3x=14
x=14/3=4 2/3
Kite=4 2/3
Tail= 1.5+2(4 2/3)=10 5/6

Answer:
the first one should be 5.28x10^-2 and the second one should be 3.2x10^6
Step-by-step explanation:
because with 0.0528 you move the decimal right twice. which makes it negative.
with 3,200,000 you assume that the decimal is at the end and move it between the three and the two. making it have 6 moves. since it moves left its positive
Answer:
0.0528=5.28*10^-2
Step-by-step explanation:
Scientific notation is a simpler way to write very large or very small numbers. In this case, you want to write a small number in simpler form. To write in scientific notation, the number being multiplied always has to be between 1 and 10. Here, it is 5.28, so we aren't breaking the rule. You can see that we moved the decimal two places to the right, which is going to make the exponent negative (the opposite applies for larger numbers). To convert to scientific notation, move the decimal place to the right or left until you get a number between 1 and 10. Then, if you moved to the right, multiply the number that is between 1 and 10 by 10 the the negative [# of spaces that you moved the decimal] power. If you moved it left, do the same but a positive exponent. To convert from scientific notation, write the number that is being multipied by 10 on a sheet of paper. if the exponent is negative, you'll have to move the decimal left for every number that the exponent is. For example, if the exponent was -5, you would move the decimal to the left 5 times. If it was just 5, you would move the decimal to the right 5 times. Then, there's your number.

if you reflect any shape across the x-axis and then rotate it 90 degrees clockwise about the origin, do you get the same results as if you reflect it across the y-axis and then rotate it 90 degress counterclockwise about the origin? what does this mean?
Answers
Yes, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise direction around the origin to achieve the same results as a shape reflected across the y-axis and rotated in a counterclockwise direction. This implies that these two transformational sequences are similar.
What is reflection in Mathematics?A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.
