I'll call the answer options A, B, C, and D, in that order from top to bottom. The line is a dotted line, so the inequality cannot be a greater/less than or equal to. Thus the answer choices B and D are eliminated. According to the graph, the point (0,0) is one of the possible solutions of the inequality. So, just substitute (0,0) into the inequalities for A and C. For C, you get 0 < -3, which is not true, so C is wrong. For A, you get 0 > -3. This is true, so the correct answer must be A, or y > -2x - 3

Answer:
Option 3 or Option 4.
Step-by-step explanation:
I have this doubt because actually, a rhombus with a right angle (one) is not necessarily a square. Some rhombuses have one right angle and are still not squares. Now, if the four angles are right, it is a square, but this only says one.
On other hand, a parallelogram with congruent diagonals isn't a square necessarily either. Rectangles have congruent diagonals and are parallelograms.
In case you only can answer with one, I'll say is option 3, hope it helps!

Answer: 67
Step-by-step explanation:
Here is the complete question:
A professor determined the relationship between the time spent studying (in hours) and performance on an exam.
Performance = 70.443 + 4.885 × (time)
Ann studied 2.6 hours for the last exam. However there was a concert in town the night before and her score was 16 points lower than expected. What was her score on this exam, rounded to the nearest integer?
Let's rewrite the formula to determine Ann's performance.
P = 70.443 + 4.885t
where t is in hours.
This is equation with P(t) means that P depends on variable t. We can then express t=2.6 in the formula to get her expected performance.
P = 70.443 + 4.885t
P = 70.443 + 4.885(2.6)
P = 70.443 + 12.701
P = 83.144
Now, since the question says that she scored 16 points less than the expected, we then need to find value of P-16
= P - 16
= 83.144 - 16
= 67.144
We can then round it to the nearest integer, this will be 67.
