If P = (-2,7), Find: Ry-axis (P) ([?], [])
1 answer:
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).

For this case we have the following polynomial:
To answer the question, what we must do is rewrite the polynomial in its standard form.
We have then that the polynomial will be given by:
Therefore, we have the ordered polynomial in descending form of exponents.
Therefore, the second term of the polynomial is:
Answer:
The second term of the polynomial is given by:
Answer:
20 mph
Step-by-step explanation:
Let speed of Train a = Va mph
Let speed of Train b = Vb mph
Va = Vb + 30
Let time taken for Train a = Ta
Let time taken for Train b = Tb
time taken = distance travelled/speed
Ta = 350/Va = 350/(Vb+30)
Tb = 140/Vb
But they both travel in the same amount of time.
So, Ta = Tb
Cross multiply
Divide both sides by 210
