Answer:
The equation of the line AB is y - x -4 = 0
Step-by-step explanation:
The points are A (10,14) and B(2,6)
Now, slope of the line AB : 
or, 
= 
So, slope of the equation AB = 1
Now, by SLOPE INTERCEPT FORM:
The equation of line is given as : y - y0 = m (x-x0)
So,the equation of line AB is y - 6 = 1(x-2)
or, y - 6 -x + 2 = 0
or, y - x -4 = 0
Hence, the equation of the line AB is y - x -4 = 0
Answer:
(C. one solution
Step-by-step explanation:
So basically you use the ratio they have given you. You either multiply by 2 if image is enlarged or divide by 2 if it is reduced. (Keep in mind I got the 2 from your ratio : 1inch : 2inches) Therefore the find the original width, you multiply 10 by 2, giving you 20 inches.
Answer:
D. greater than 8 cm and less than 70 cm
Step-by-step explanation:
Given:
Length of one side = 39 cm
Length of other side = 31 cm
We need to find the length of third side.
Solution:
to find the length of third side we will use triangle Inequality property which states that;
"The length of the third side should be less than sum of the other two side."
Also;
"The length of the third side should be greater than difference of the other two sides."
Now Sum of 2 sides of triangle = 39 + 31 =70 cm
Also Difference of 2 side of triangle = 39 -31 = 8 cm
Hence The length of the third side should be greater than 8 cm and less than 70 cm.
