Step-by-step explanation:
if she cut 3 inches off the length, that makes it 9 inches. the original rectangle was 2 inches longer. so subtract 2 from 9 and 7. she needs to have the width 7 inches.
Answer:
The equation that models the relationships between 
, the number of hours Mark reads, and , 
the number of pages of the book he reads is:
Step-by-step explanation:
Given:
Mark reads 42 pages every 
hour.
The number of hours is given by =
The number of pages is given by =
The equation can be modeled as:
where 
represents rate of change and 
represents the y-intercept or the initial value.
Rate of change =
The initial value 
as Mark starts reading from 0.
So, the equation is:
∈ ≤ ≥
-6 ≤ 2x + 6 ≤ 6 ( seperate the two inequalities)
2x + 6 ≥ - 6
2x + 6 ≤ 6 (solve the inequalities)
x ≥ -6
x ≤ 0 (find the intersection)
solution is : x ∈ { -6, 0 }
Answer:
No
Step-by-step explanation:
Since 1/2 =0.5
0.5 > 0.4
Therefore
1/2 >0.4
