82 less than r is less than -164

Oliga [24]

Answer:

82<r<-164

Step-by-step explanation:

We need to form an inequality of the given statement.

82 less than r is less than -164

Less than is written as <.

82 less than r means, 82<r

r is less than -164, r<-164

Combining two statements,

82<r<-164

Hence, the expression for 82 less than r is less than -164 is 82<r<-164.

What is the y-intercept of the line y + 11 = –2(x + 1.5)? y-intercept =

Lana71 [14]

y + 11 = –2(x + 1.5)

y=mx+b

multiply the bracket by -2

(-2)(x)=-2x

(-2)(1.5)=-3

y+11=-2x-3

move +11 to the other side

sign changes from +11 to -11

y+11-11=-2x-3-11

y=-2x-14

m is also the slope

b= y-intercept

Answer:

y-intercept=-14
