7) On Friday, November 24, 2017, the Iowa Hawkeyes football team played the Nebraska Cornhuskers. There were 70 total points scored in the game. Iowa scored 42 more points than Nebraska. a) Using “I” and “N” as your variables, write a system of equations to represent the situation. (1 pt) b) Solve the system of equations to find out how many points each team scored. (2 pts)

114

Step-by-step explanation:

70 + 42 = N

114 = N

N = 114

answer: no

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
