Answer:
jajajaja
Step-by-step explanation:
Testing my knowledge on this one.
A - when doing a 180 degree rotation, the coordinates (x,y) would become
(-x,-y), in other words, the inverse of the numbers in the x and y
places, (-1,2)->(1,-2)
B - when reflecting over the x axis, only the y coordinate inverts, (x,y) becomes (x,-y), (1,-2)->(1,2)
I believe the answer is H,
Karen had a gift card for $150. She bought 3 gifts for her sister. The gifts cost the same amount, X. After paying for the gifts, her card had a balance of $60. How much did each gift cost?
When you multiply by distribution, the answer is: x^2 + 7x + 10. the middle term is 7x

Answer: No, it is not a solution</h3>
Explanation:
Refer to the diagram below. The point (-4,3) marked in red is outside the blue shaded region. So it doesn't make both inequalities true, and therefore not considered a solution.
In contrast, a point like (-5,1) is a solution as it is in the shaded region.
Put another way, the set of all solution points must be below both the solid line and the dashed line. Points can be on the solid line, but must be adjacent to the blue shaded region. The fact (-4,3) is on the solid line doesn't count because its not below the dashed line.
