two
Step-by-step explanation:
Two
x - 1 = 0
x = 1
x + 3 = 0
x = - 3
You can see them for your self. The roots are the points where the graph cuts the x axis.
(1,0) and
(-3,0)
Answer:
D
Step-by-step explanation:
A coordinate grid is shown from negative 5 to 0 to 5 on both x- and y-axes. A polygon ABCD has A at ordered pair (2, 3), B at ordered pair (4, 4), C at ordered pair (3, 1), D at ordered pair (2, 1). A polygon A'B'C'D' has A' at ordered pair (-1, 3), B' at ordered pair (-3, 4), C' at ordered pair (-2, 1), D' at ordered pair (-1, 1).
Which of the following sequences of transformations is used to obtain figure A'B'C'D' from figure ABCD? (1 point)
a
) Counterclockwise rotation by 90 degrees about the origin followed by a translation to the right by 1 unit
b) Counterclockwise rotation by 90 degrees about the origin followed by a translation to the left by 1 unit
c
) Reflection about the x-axis followed by a translation to the left by 1 unit
d
) Reflection about the y-axis followed by a translation to the right by 1 unit
Answer: Translate triangle ABC so that point B lies on point D to confirm ∠B ≅ ∠D.
Step-by-step explanation: Since we already know that angle A is congruent to itself by the reflexive property, all we need is another pair of corresponding angles to be congruent according to the AA (angle-angle) similarity postulate. This postulate states that; If two corresponding angles of two or more triangles are congruent, the triangles are similar. So when we translate triangle ABC so that point ∠B lies on ∠D, we prove that these two angles are congruent.
I also got it right on the test. So... yeah.
hope this helps dood.
Answer:
<h2>(90Degree)(0.3Degree/1min) = 300min</h2><h2>since 60min = 1hr</h2><h2>(300min)(1hr/60min) = 5hrs</h2>
