Answer:
The units of the displacement are (3, 5) → T (x + 3, y + 5)
Step-by-step explanation:
The rules of translation of a point
- If the point (x, y) is translated h units to the right and k units up, then its image is (x + h, y + k)
- If the point (x, y) is translated h units to the right and k units down, then its image is (x + h, y - k)
- If the point (x, y) is translated h units to the left and k units up, then its image is (x - h, y + k)
- If the point (x, y) is translated h units to the left and k units down, then its image is (x - h, y - k)
∵ Point (4, 2) is translated by (h, k)
∵ Its image is (7, 7)
∴ The x-coordinate of the point is increased from 4 to 7
∴ The point is translated to the right by h units
∵ 4 + h = 7
∴ h = 7 - 4 = 3
∴ The point is translated to the right 3 units
∵ The y-coordinate of the point is increased from 2 to 7
∴ The point is translated up by k units
∵ 2 + k = 7
∴ k = 7 - 2 = 5
∴ The point is translated up 5 units
∴ The point is translated 3 units right and 5 units up
∴ The units of the displacement are (3, 5) → T (x + 3, y + 5)
Answer:
2,535,008
two million , five hundred thirty five thousand, eight
Step-by-step explanation:
3/0.4
mutilply both by 10
=30/4
= 7.5
Rise is change in y
Run is change in x
Change in x
4-2=2
Change in y
120-60=60
Rise over run
60/2=30
Final answer: B, 30
Answer is B and C
<IRF = <MRN
<QRT = <QRU
