By looking at the table, we can see that the y values are equal to the x values multiplied by 3.
3x = 3*3 = 9
3x =3*9 = 27
3x=3*13=39
3x= 3*20= 60
So, it is a direct variation and the function is y=3x
Answer:
option b,c,d
Step-by-step explanation:
Given choices are
A: x^2-5x+6
B: 11> (w-4)^2
C: y< 3^4
D: 5+9<5\cdot 95
E: \dfrac{z+11}{2z-1}
Inequality is the phrase that contains variables or numbers and inequality symbols like < or > or <= or >=
option A goes not have inequality symbol , so it is not an inequality
Option B has > symbol. It is an inequality
Option C has < symbol. It is an inequality
Option D has < symbol. It is an inequality
Option E has only fraction. So it is not an inequality
Here we would use the idea that the post and its shadow form a triangle and the tree and its shadow form a triangle and the side lengths of these two triangles are of the same ratio, ie. if the height of the tree is given by h then:
5/8 = h/48
h = 48*(5/8)
h = 6*5 = 30
Thus the tree is 30 ft tall
