N^2 +5n -1 evaluate the expression when n = -6

5

Step-by-step explanation:

substitute n=-6 into the expression

therefore, (-6)^2+5(-6)-1=36-30-1

=5

5

Step-by-step explanation:

1) N is equal to -6 and you are challenge to find the value in the expression n²+5n -1.

so we have:-

n= -6

the expression is n²+5n-1

2) next we substitute the value of n= -6 in the expression n²+5n-1. this means wherever we see 'n' in the expression, we replace it with '- 6 ' so instead of writing n we will write the value -6. thus we have:-

(-6)² + 5(-6) - 1

36+ (-30) - 1

36-30-1

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
