18, because cats would be 3, and then the dogs would be 6 times that, which would be 18. 18 + 3 = 21.
Answer:
expression: y = 3.6x
for x = 11, then y = 39.6
Step-by-step explanation:
Direct variation uses the following equation:
y = kx
For each case, there will be an actual number instead of k.
We need to find which value of k our problem uses. We can use teh given x and y values, and solve for k.
y = kx, use x = 5 and y = 18, and solve for k
18 = k * 5
k = 18/5 = 3.6
In our case, k = 3.6, so the specific equation for direct varuiation for this problem is
y = 3.6x
Now we can find y when x = 11.
y = 3.6x
y = 3.6(11)
y = 39.6
A) x = 3
b) x = -1
c) x = -9
d) x = 25
e) x = 8
f) x = -29
g) x = -1
h) x = 4/6
