y≥-3x+4
Step-by-step explanation:
Answer:
The cost of 7 roses and 8 petunias is $9001
Step-by-step explanation:
We are given expression for cost as
where
r is number of roses
p is petunias
We are given
r=7
and
p=8
so, we can plug here
now, we can simplify it
and we get
So,
The cost of 7 roses and 8 petunias is $9001
So this is direct proportional question
so y=(k)x
sub y=48 and x=6
48=6k
k=8
now you got a constant k
now sub x=3
y=(8)(3)
=24
Not at alll . Multiply by 5 and you wouldnt get 5/25
Answer:
36
Step-by-step explanation:
Since f(x) varies directly with x, f(x) can be expressed alternatively as \[f(x) = k * x\] where k is a constant value.
Given that f(x) is 72 when the value of x is 6.
This implies, \[72 = k * 6\]
Simplifying and rearranging the equation to find the value of k:
k = \frac{72}{6}
Hence k = 12
Or, \[f(x) = 12 * x\]
When x = 3, \[f(x) = 12 *3 \]
Or in other words, the value of f(x) when x=3 is 36
