What are the coefficients of -4x - 7y + 21z?

-4

-7

21

Step-by-step explanation:

a coefficient is the number before the variable

-4, -7, 21

Step-by-step explanation:

Coefficients are a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x)

So in this problem -4, -7 and 21 are the coefficients

i can't see the picture : /

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

happy to
