Answer:
C
Step-by-step explanation:
To determine which point is a solution substitute the coordinates into both inequalities and check validity
A (2, 0 )
2 + 0 = 2 ← not greater than 2
(4 × 2) + 0 = 8 > - 1
The point (2, 0) is not a solution as it does not satisfy the first inequality
B (0, 2 )
0 + 2 = 2 ← not greater than 2
0 + 2 = 2 > - 1
The point (0, 2) is not a solution as it does not satisfy the first inequality
C (0, 3 )
0 + 3 = 3 > 2
0 + 3 = 3 > - 1
The point (0, 3) satisfies both inequalities and is therefore a solution
Answer:
2
Step-by-step explanation:
The slope of a line is rise/run.
First, you must choose any two points on the line.
Rise is how many spaces a line moves upward or downward from one point to another.
The run is how many spaces a line moves left or right from one point to another.
It is given that from point M to point N, the line moves up 4 spaces and runs to the right 2 spaces.
- 4 = rise
- 2 = run
- Slope = 4/2, which can be simplified to 2, because 4 divided by 2 is 2.

Answer: Choice A
3 over 12 multiplied by 7 over 11
(3/12) * (7/11)
=============================================
Explanation:
There are 3 yellow cars out of 2+7+3 = 12 total. The probability of selecting yellow is therefore 3/12. We can reduce this, but the answer choices decide not to, so we'll do the same.
After picking a yellow car, we have 12-1 = 11 left over. The amount of blue cars do not go down (because we haven't selected it yet). There are 7 blue cars out of the 11 total, so the probability of picking blue for this case is 7/11
Multiply the two fractions to get (3/12)*(7/11) which is a shorthand way of writing "3 over 12 multiplied by 7 over 11".
