Answer:
(5,-6) is a solution
Step-by-step explanation:
Given
Required
Tell whether (5,-6) is a solution
In (5,-6): x = 5 and y = -6.
Substitute these values in the given equations
becomes
becomes
Because both solutions are true, then (5,-6) is a solution
Answer: b. (2, 0)
<u>Step-by-step explanation:</u>
L = (-3, 3)
down 3 units means subtract 3 from the y-coordinate
new L = (-3, 0)
left 1 units means subtract 1 from the x-coordinate
newer L = (-4, 0)
reflection across x = -1 means measure the distance of the x-coordinate from x = -1 and move it to the other side that same distance. (-4 - (-1) = 3. --> -1 + 3 = 2
L' = (2, 0)
Answer:
x = 25/4
Step-by-step explanation:
Because of the known similarity of the triangles, we know that
10 x
----- = ----
16 10
Cross-multiplying, we get 16x = 100, and thus x = 100/16 = 50/8 = 25/4
x = 25/4
99/110
