The variable of interest would be whether or not their eyes were affected.
Variables of interest are like independent variables, they are the variable that you are testing for change.
Hello :
let the equation : y = ax+b
<span>xx-intercept (4.5,0) : 0 = a(4.5) +b .... (1)
</span><span>yy-intercept (0,-5.4) .: - 5.4 = a(0)+ b .....(2)
by (2) : b = - 5.4
subsct in (1) : 4.5a -5.4 = 0
a = 5.4/4.5
a = 54/45
a = 6/5
</span><span>the equation of the line (in slope intercept form) is : y =(6/5)x - 5.4</span>
Answer:
Step-by-step explanation:
Answer:
4x2 − 3x = 0
Factorization:
x(4x − 3) = 0
Solutions based on factorization:
x = 0 ⇒ x1 = 0
4x − 3 = 0 ⇒ x2 = 34 = 0.75
hope this helps if wrong sorry
