Answer:
x - 3/4 is a zero
Step-by-step explanation:
f(x) = x+3/4
To find the zeros, set f(x) =0
0 = x+3/4
Solve for x
Subtract 3/4 from each side
0-3/4 = x+3/4-3/4
-3/4 =x
The zero is -3/4
for number 10a is 4,10,16,22
10c is 3,6,12,24
1) In a proportion: y/x=k
k is your constant of proportionality.
x is your independent variable and y is your dependent variable.
Since you need 3 oz of flour for each 2 oz of sugar, y=3 and x=2.
So k=1.5 (3/2)
3)
a) y/x as a showed above. This question is very similar to #1.
b) y/x=k
