Offers are parallel because they would never intersect
Answer:
Step-by-step explanation:
Given the inequality
0.21x + 0.05(17 - x) > 2.55 where x is the amount of 21% lotion needed
Given
0.21x + 0.05(17 - x) > 2.55
Open the parenthesis
0.21x + 0.85-0.05x > 2.55
Collect like terms
0.21x-0.05x+0.85>2.55
0.16x+0.85>2.55
0.16x>2.55-0.85
0.16x > 1.7
x > 1.7/0.16
x > 10.625
Hence she will need 21% lotion approximately greater than 10 ounces
I can't factor that.
Is the equation input correctly?
Answer:
5 bags
Step-by-step explanation:
Given Marianne buys 16 bags of potting soil which come in 5/8 pound bags
The above provides 10pounds of potting soil already
Now her father says he needs 13 pounds So Marianne should get an extra of 13 - 10 =3 pounds of potting soil
We know that 1 bag contains 5/8 pounds of potting soil
x bags contain 3 pounds of potting soil
On cross multiplication we get

x =
since x is an integer x = 5 bags
Note that an extra amount of soil will be remained unused
We can use the vertex form

to find the equation of the graph. We know that a is the coefficient, and since the graph opens upwards and is slightly stretched vertically, we know that a is 1/3. On the graph, we see that the vertex of the parabola is at (0,-1). Therefore, h is 0 and k is -1.
Our vertex form equation is

Which is D
