Answer:
x= -2
Step-by-step explanation:
x = -5 is a vertical line, so a line parallel would also have to be a vertical line
It goes through the point ( -2,6)
The x coordinate -2
So a line parallel would be x= -2
The stemplot is a type of frequency data that is presented in table form. It is like a histogram, but you don't use bars. Instead, you make a table where the left side represent the stem, while the right side represent the leaves.
First, arrange the data set from lowest to largest. Then, sort the numbers based on their tens digit. All the common tens digit should be placed on the stem side. The corresponding ones digit are placed in the leaves side, in which they are placed side by side. Fro example, for the data group: 12, 15, 17 ,19. The left side would be 1, then the right side are numbers containing 2, 5, 7 and 9, The stemplot is shown in the attached picture.
To determine the center, just literally find the central data by counting from both ends of the stemplot, until you reach the center. That would be 22, as encircle in the picture. Next, the spread is the topmost number to the bottom. Thus, the range is from 5 to 57. Lastly, the shape of the stemplot is determined by looking at the length of the leaves. The top leaves only contain number, while the bottom leaves contain 2 or 3 numbers. Thus, the spread is bottom-skewed, or more distributed in the bottom area.
20, 18 because they are decreasing by a factor of 2
Answer:
x=3 and y=3
Step-by-step explanation:
explanation for x
using distributive property, 3(2x+10) should be 6x + 30 because you need to multiply both inside numbers by the outside number.
Next, you need to isolate the variable so the 12 is suptracted from thirty which leaves you 6x+18 and 12x. Since six is half of twelve, six is half of the other side, and then there is 18 which is the other six, so that means 6x=18, so simplifies, x=3 because 6×3=18
explanation for y
2(2y-3) using the distributive property, should be 4y-6. Take the 12 from 2y+12 and subtract six from it and you get 2y+6 and 4y. So, since 2y plus 6 equals 4y, 2y is half of 4y and then there is a plus six, which equals the other half, so 2y=6, and simplified, y=3
