Answer:
See below for the methods.
Step-by-step explanation:
Lengths of line segments between 2 given points are found using the following formula:
If the point are (x1, y1) and (x2, y2).
the length = √ [(x2 - x1)^2 + (y2 -y1)^2]
so for the question 2. b where the points are (2, 7) and (-3, -4):
the length of line segment = √ [ (-3-2)^2 + (-4-7)^2]
= √[ 5^2 + (-11)^2
= √25+121
=√146
= 12.08 to nearest hundredth.
3. The slope (gradient) of the line joining (x1, y1) and (x2, y2)
= (y2 - y1) / (x2 - x1).
For example:
2a.
The 2 points are (-4, 2) and (4, -2)
Gradient = ( -2 - 2) / (4 - (-4))
= -4/8
= -1/2.
Answer:
95 degrees
Step-by-step explanation:
The sum of the measures of a quadrilateral is 360 degrees. 360-105-80-80 = 95 degrees
Answer:
Table is attached with values, but answers are:
(0, 0) (1, 3) (2, 6) (3, 9)
Step-by-step explanation:
y = 3x
Substitute all values.
y = 3(0)
y = 0
0, 0
y = 3(1)
y = 3
1, 3
y = 3(2)
y = 6
2, 6
y = 3(3)
y = 9
3, 9
Tough sorry wish I could help u can’t too hard but I think it is equivalent to the other triangle so I think it’s 31? I THINK
