Answer:
12 books
Step-by-step explanation:
30 multiply by 2/5=12 books that were sold to co-workers.
3/5 which is the remainder multiplied by 1/2 =3/10
3/10 multiply by 30 =6 books sold to her neighbours
now that 30 is the original subtract12 +6
a) The variable in the inequality is <u>x.</u>
b) The inequality symbol needed <u>< ( or >)</u>
c) The constant is <u>8.</u>
d) The inequality is <u>f(x)<8x .</u>
Step-by-step explanation:
Given,
The person can make less than $8 per hour
To find the correct inequality for this situation.
Let us take,
The person works for x hours.
If the total income of the person for x hours is f(x)
Then, the inequality will be
f(x)<8x
Answer: She combined unlike terms.
Step-by-step explanation:
You can only combine like terms. If a number has a variable, you must make sure that the number you're operating it with has the same variable raised to the same power (if applicable)
6.8w-4.7 is in its simplest form.
To be able to subtract these, 4.7 must have a ''w'' variable as follows;
6.8w-4.7w=2.1w
Answer:
D. y = (x - 3)²
Step-by-step explanation:
The parabola formula in vertex form is:
y = a(x - h)² + k
where the vertex is located at (h, k). Replacing with vertex (3, 0) we get:
y = a(x - 3)² + 0
y = a(x - 3)²
In all possible options the leading coefficient <em>a</em> is equal to one. Therefore:
y = (x - 3)²
