Answer:
Charlene cannot bring 20 books because the weight of her luggage will be more than the permitted weight. She can only bring at most 15 books
We can represent this inequality as:
5 + 3x ≤ 50
Step-by-step explanation:
Whenever we are dealing with inequalities, a good trick is to solve the problem using an "equals to" sign and change it to the "inequality" sign at the last minute.
Let us assume that she carries x books.
The weight of her suitcase + the weight of all the 3-pound books must not be more than 50 pounds.
We can represent this inequality as:
5 + 3x ≤ 50
having said this, to find the value of x, which is the maximum number of books she is allowed to carry.
To do this, we replace the inequality sign with the "equals to" sign
5 + 3x = 50
from this, we have that
3x = 45;
x = 45/3
x = 15 books
From this, we can see that Charlene is not allowed to carry more than 15 books.
i.e x ≤ 15
Charlene cannot bring 20 books because the weight of her luggage will be more than the permitted weight. She can only bring at most 15 books
Answer:
D)
Step-by-step explanation:
Substitute it into equation, for (-1,1): -2*(-1) - 1 = 2 -1 = 1, and -2*4 - 1 = - 8 -1 = -9, so D) is correct.

Answer:
t=0
Step-by-step explanation:
if the slope is 3 the y coordinate with increase by 3 every time the x coordinate goes up 1. So when the x coordinate goes up 1 from 9 to 10, the y coordinate goes up 3 from -3 to 0.
The answer is 112
The volume is 448
You are asked to dilate it to a scale factor of 1/4
All you are doing is multiplying: 448/1 × 1/4
