I will mark brainliest Annette is surveying people in the city about their interest in a new shopping mall. She found that 180 people, or 30% of those surveyed, do not want a new mall. How many people did Annette survey?

(if you answer this may you please show your work)

54

Step-by-step explanation:

30 percent * 180 =

(30:100)* 180 =

(30* 180):100 =

5400:100 = 54

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
