Answer:
17
Step-by-step explanation:
because 19 students for the other in total (you add the ones who study biology and the ones who study both, then you minus the group of students by 19)
This is a simple percentage question. 6/100 * 1000 = 60 people have forgotten
Answer:
C, y=-2/3x+1
Step-by-step explanation:
using points (0, 1) and (3, -1) obtained from the graph:
slope = -1-1/3-0 = -2/3
use one of the points above lets take (1, 0) and another point (x,y)
slope = y-0/x-1 = -2/3
y=-2/3x+1
Answer:
A
Step-by-step explanation:
this is a fraction we two powers with the same base so we have tu subtract the exponents and maintain the same base
5^(-6-3) = 5^-9 = 1/5^9
Answer:
x + 2y - 5 = 0
Step-by-step explanation:
We can see that , the graph passes through (0,2.5) and (5,0) . Therefore the ,
- x intercept is 5
- y intercept is 2.5
We can use the intercept form of equation as ,
=> x/a + y/b = 1
=> x/5 + y/2.5 = 1
=> x + 2y/5 = 1
=> x + 2y = 5
=> x + 2y -5 = 0 .
This equation can be verified by plotting the graph .[ Refer to attachment ]
