A football team is known to run 40% of its plays to the left and 60% to the right. A linebacker on an opposing team notices that, when plays go to the right, the right guard shifts his stance most of the time (80%) and that he uses a balanced stance the remainder of the time. When plays go to the left, the guard takes a balanced stance 90% of the time and the shift stance the remaining 10%. On a particular play, the linebacker notes that the guard takes a balanced stance.

48+y= ?

the y is the variable and the ? could also be a variable  

b: y = 2x + 2

step-by-step explanation:

y = 2x + 1

we want a line that is parallel, so it will have the same slope

the line is in the form y= mx+b, so the slope is 2

we have a slope and the y intercept (0,2)

since x is 0 we know the y point which is the y intercept

we can use y= mx+b to write the equation of the line

m is the slope and b is the y intercept

y = 2x +2

the first sequence is an arithmetic sequence.

answer: a. 40 sq. units

step-by-step explanation:

pretty simple, since the rectangle is 80 and the triangle is half of it, divide by 2. you'll get 40 afterwards.

hope it ; d.
