Answer:
y = 1/2x -5 slope intercept form
y-1 = 1/2(x-12) point slope form
Step-by-step explanation:
We can find the slope of this line by using
m = (y2-y1/(x2-x1)
= (1--7)/ (12 --4)
= (1+7)/(12+4)
= 8/16
= 1/2
We know the slope and a point, so we can use point slope form
y-y1 = m(x-x1)
y-1 = 1/2(x-12)
y-1 = 1/2 x -6
Add 1 to each side
y-1+1 = 1/2x -6+1
y = 1/2x -5
This is in slope intercept form
Answer:
x = 84 , y = 168
Step-by-step explanation:
I think its shear, because that is the only one in which the shape actually changes shape and size
Answer:
The weight of 12 tennis balls = 691. 2 grams
Step-by-step explanation:
The weight of each tennis ball = 57.6 grams
So, the weight of 12 balls = 12 x ( weight of 1 ball)
= 12 x 57.6 grams
= 691.2 grams
⇒12 balls weigh 691.2 grams
Hence, the weight of 12 tennis balls = 691. 2 grams
