Answer:
see explanation
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ) , thus
C)- 8, - 4 ) → C'(- 4, 8 )
D(0, - 4 ) → D'(- 4, 0 )
E(- 8, - 9 ) → E'(- 9, 8 )
Step-by-step explanation:
The hypotenuse of a right-angled triangle = 25 cm
One side is twice as long as the other.
Let the other side is x.
First side = 2x
Using Pythagoras theorem to find the lengths of the shorter sides.
So, the other side = 11.18 cm
First side = 2(11.18) = 22.36 cm
So, the lengths of the shorter sides are 11.18 cm and 22.36 cm.
D, it’s the only answer that equals 30. When splitting up the 6, you’re doing the distributive property, which is what D is doing.
To choose the graph, we must make sure that it satisfies both equations of the system simultaneously.
We have then:
a line includes points 0 comma 4 and 3 comma 5
Verifying:
(0, 4)
(0) - 3 (4) = -12
0-12 = -12
-12 = -12
(3, 5)
2x - y = 1
2 (3) - (5) = 1
6-5 = 1
1 = 1
answer
The graph that matches the system of equations is
a line includes points 0 comma 4 and 3 comma 5
