Answer:
B) 7/3
Step-by-step explanation:
To find the slope of a line using a graph, locate two points. In this example, the points are (0, -2) and (3, 5).
Then, find the distance between the two points. To do so in this example, find the difference between 0 and 3, and -2 and 5.
3 - 0 = 3
5 - (-2) = 7
Since we're dealing with slope, the answer will be in y/x form. 7 is the distance between the y-coordinates and 3 is the difference between the x-coordinates, the answer is 7/3.
A straight line can be drawn through all the points and the line passes through the point where x=0 and y=0. This best describes a graph of paired points that form a proportional relationship. You can tell this because the line passes directly through the origin (0,0). It also says that it is a straight line that passes through the points, so most likely the line will contain points that have a proportional relationship. Hope that helps :)
Answer:
12x6+2(6-1)
72+2x5
72+10
82
82 is the answer.
Step-by-step explanation:
Just replace the X's in the problem with 6.
Answer:
Gọi AH là đường cao kẻ từ A đến BC
Xét tam giác AHC vuông tại H
Suy ra AH = HC. cotA= 9.cot35° = 12,9
Xét tam giác AHB vuông tại H
Suy ra BH = AH.tanA = 12,9.tan61°=23,37
Ta có BC= HC+ HB= 9+23,27 =32,27
Diện tích tam giác ABC = 1/2 × AH ×BC= 1/2 ×12,9×32,27=208,1415
