Answer: 3a-21
Step-by-step explanation:
Apply distributive property
a=3-3*7
Multiply 3*7=21
Answer: 3a--21
Answer: D: s∈ (-∞, 3]
Step-by-step explanation:
When we have a function:
y = f(x)
The domain is the set of the possible values we can input in f(x).
In this case, we have:
y = √(3 - s)
Where our variable is s.
So we want to find the possible values of s we can input in that function.
Remember that if y is a real number, then we can not have a negative number inside the square root, because it will lead to an complex solution.
Then the argument of the square root needs to be equal to or larger than zero.
This means that:
3 - s ≥ 0
From this inequality, we can find the possible values of s, which will be the domain.
We need to isolate s.
3 ≥ s
This means that s needs to be smaller than or equal to 3.
Then the domain is:
D: s∈ (-∞, 3]
Answer:
$20,000 = sales
Step-by-step explanation:
Giving the following information:
Fixed salary= $300
Commission rate= 1% of sales
<u>First, we need to establish the net income formula:</u>
Net income= 300 + 0.01*sales
<u>Now, the sales required for $500 net income:</u>
500= 300 + 0.01sales
200/0.01 = sales
20,000 = sales
Prove:
Net income= 300 + 0.01*20,000
Net income= $500
Answer:
-3 is the value of k in g(x)=kf(x)
Step-by-step explanation:
Both functions cross nicely at x=-3 so I'm going to plug in -3 for x:
g(x)=kf(x)
g(-3)=kf(-3)
To solve this for k we will need to find the values for both g(-3) and f(-3).
g(-3) means we want the y that corresponds to x=-3 on the curve/line of g.
g(-3)=-3
f(-3) means we want the y that corresponds to x=-3 on the curve/line of f.
f(-3)=1
So our equation becomes:
g(-3)=kf(-3)
-3=k(1)
-3=k
So k=-3.
