A zoo has 15 emperor penguins The emperor penguins make up 30% of all the penguins at the zoo. How many penguins live at the zoo
r-ruslan [8.4K]

Let x + 15 = total penguins

15/ (x +15) = .30

15 = .30x + 4.5

.30x  = 10.5

x = 35

Total penguins = 15 + 35 = 50

Double Check

15 / 50 * 100 = 30%  Correct!!!

What is the point and slope of the line represented by the equation below y-4=-5(x+3)
Vedmedyk [2.9K]
The slope is -5.
The point is (-3, 4)
The formula for point slope form is
y-y1=m(x-x1) where y1 and x1 are the coordiantes of the point and m is the slope.
This shows that the y coordinate is positive and the x coordinate is negative.
May seem counterintuitive. So just flip signs that you see in formula to make the actual point if you are confused.
