Answer:

Step-by-step explanation:
first find the slope using the above points then use the slope formula to calculate the slope

substitute ⅔ for m and one of the above points into the y-intercept form of the equation for a line and solve for b

substitute the slope and the value for b into the equation to get the answer

Answer:
bro can u see the answers?
the answer is -65y+11x/10
Step-by-step explanation:
The side with all the 9s and x is 12 just like its opposite side because this is a parallelogram. We can write the equation to add up the three segments; the ones on the left and right are 9-x:
9-x + x + 9-x = 12
18 - x = 12
x = 6
The answer is 40 inches. Reason is a^2 + b^2 = c^2. A is 42. B is unknown. C is 58. Taking that information it is 40 inches
