Answer:
(2, 7)
Step-by-step explanation:
represents the reflection of a point P about the y-axis.
If a point (x, y) is reflected across y-axis, rule for the reflection is,
(x, y) → (-x, y)
If a point (-2, 7) follows the same rule, coordinates of the image point will be,
P(-2, 7) → P'(2, 7)
Therefore, answer is (2, 7).
Answer:
The friends live 285 miles apart.
Step-by-step explanation:
Let total distance in miles Sean needs to cover to visit his friend be =
On first hour distance traveled in miles is =
Distance left to cover after first hour =
On second hour distance traveled = 34 miles
Distance to still left to be covered = 194 miles
Total distance to be covered after first hour will be = = 228 miles
Thus, the equation can be given as:
⇒
Multiplying each term with 5 to remove fractions.
⇒
⇒
⇒
Dividing both sides by 4.
⇒
∴
Thus, the friends live 285 miles apart.
