Answer:the number of 2 legged animals in the zoo is 9
the number of 4 legged animals in the zoo is 7
Step-by-step explanation:
Let x represent the number of 2 legged animals in the zoo.
Let y represent the number of 4 legged animals in the zoo.
There a 46 legs in the exhibit in the zoo. This means that
2x + 4y = 46 - - - - - - - - - -1
There are 2 more 2 legged animals than 4 legged animals. This means that
x - 2 = y
Substituting y = x - 2 into equation 1, it becomes
2x + 4(x - 2) = 46
2x + 4x - 8 = 46
6x = 54
x = 54/6 = 9
Substituting x = 9 into x - 2 = y, it becomes
y = 9 - 2 = 7
If a line is perpendicular to other his slopes are the opposite inverse of each other
So, if y = -2x - 4 we have the slope of -2, so the slope of the other line will be the opposite inverse which means
opposite of -2 = 2
inverse of 2 = 1/2
So our slope is 1/2
(y - yo) = m.(x - xo)
(y - 4) = 1/2.(x - 3)
y - 4 = x/2 - 3/2
y = x/2 - 3/2 + 4
y = x/2 + 5/2
Answer:
h(2x - 3) = 4x - 5
Step-by-step explanation:
If h(x) = 2x + 1
h(2x - 3) = 2(2x - 3) + 1 = 4x - 5
180 degrees in a triangle. so 180-90-31=59
140,000. the hundred is under 5 so you round down
