Answer:
Step-by-step explanation:
1. Add 19 to both sides.
2. Divide both sides by 2.

Answer:
32 units squared
Step-by-step explanation:
When we plot these points on the xy plane, we will see that it makes a rectangle with the dimensions 4 by 8.
The area of a rectangle is given by , where l is the length and w is the width. Here,
= 8 and w = 4. So: A = 8 * 4 = 32.
Thus, the answer is 32 units squared.

Answer:
Option B) {(1, -1), (-3, -3), (2, 4)}
Step-by-step explanation:
<u><em>The correct inequality is </em></u>
The solution of the inequality is the shaded area above the dashed line
see the attached figure to better understand the problem
we know that
If a ordered pair satisfy the inequality, then the ordered pair must lie in the shaded area of the solution
<u><em>Verify each case</em></u>
case A) {(6, 1), (-1, -3), (4, 4)}
ordered pair (6,1)
For x=6, y=1
substitute in the inequality
---> is not true
therefore
The point not satisfy the inequality
case B) {(1, -1), (-3, -3), (2, 4)}
ordered pair (1,-1)
For x=1, y=-1
substitute in the inequality
---> is true
so
The point satisfy the inequality
ordered pair (-3,3)
For x=-3, y=3
substitute in the inequality
---> is true
so
The point satisfy the inequality
ordered pair (2,4)
For x=2, y=4
substitute in the inequality
---> is true
so
The point satisfy the inequality
therefore
The set contains only points that satisfy the inequality
case C) {(1, -1), (-3, -3), (4, -2)}
ordered pair (4,-2)
For x=4, y=-2
substitute in the inequality
---> is not true
therefore
The point not satisfy the inequality
case D) {(-1, -3), (-3, -3), (2, 4)}
ordered pair (-1,-3)
For x=-1, y=-3
substitute in the inequality
---> is not true
therefore
The point not satisfy the inequality
Answer:
C. 125
Step-by-step explanation:
Given:
Bacteria on day 1 = 5
On day 2, each bacteria got split into 5.
So, number of bacteria on day 2 =
Now, again on day 3, each of the 25 bacteria got split into additional 5 bacteria.
So, number of of bacteria on day 3 =
Therefore, the population of bacteria on day 3 is 125.
