Answer:
Rotational symmetry of 180° about the origin: Yes.
Rotational symmetry of 270° about the origin: No.
Explanation:
A figure is a rotationally symmetrical if it look the same after a given turn.
We have to analyze if the parallelogram has rotational symmetry of 180° or 270°. picture the figure rotating a given amount of degrees to see if it looks the same or not.
180 degree rotation:
We can see that the figure looks the same after a 180° rotation.
270 degree rotation:
We can see that the figure does not look the same after a 270° rotation.
So the answer will be:
Rotational symmetry of 180° about the origin: Yes.
Rotational symmetry of 270° about the origin: No.
(0,346)(2,344.8)
slope = (344.8 - 346) / (2 - 0) = -1.2 / 2 = -0.6
y = mx + b
slope(m) = -0.6
(0,346)...x = 0 and y = 346
now we sub and find b, the y int
346 = -0.6(0) + b
346 = b
so ur equation is : y = -0.6x + 346....with x being the number of weeks
after 4 weeks...
y = -0.6(4) + 346
y = - 2.4 + 346
y = 343.6 <==== after 4 weeks
after 9 weeks..
y = -0.6(9) + 346
y = -5.4 + 346
y = 340.6 <=== after 9 weeks
The answer would <span>be <span>3250</span>.</span>
Answer:
4(x+2) = 4*x + 4*2 = 4x+8
3(a+2) = 3*a + 3*2 = 3a + 6
2(x+3) = 2*x + 2*3 = 2x +6
Hope this help you :3
Answer: x=9 is an extraneous solution
Step-by-step explanation:
Given
Function is 
for function to exist
Therefore, 9 satisfies the above equation. It is it's extraneous solution.
