Angle a and angle b are similar angles

5x-18=3x+42
-3x -3x
2x-18=42
+18 +18
2x=18
/2 /2
X=9

Angle A=5(9)-18
A=27

hi im 7th grade and i feel like people think i smell when i do everything to not smell. i wake up take a shower with soap aplly
mr_godi [17]

Answer:

Step-by-step explanation:

This might be a hygiene problem. What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process. If deodorant isn’t good enough , I recommend perfume, the perfume smell lasts longer than deodorant I would think. But shower everyday, full clean down, but if ur hygiene is ok, I recommend going to the doctor for a checkup. Hopefully your problem will be resolved. Also use lotion.

which transformation causes the described change in the graph of the function y = cos x? the transformation results in a horizon
luda_lava [24]
The transformations that can occur to the graph of the function y = cos x that will exhibit changes would be changes to the angle, or changes to the coefficient. The transformations can be viewed as follows:

y = cos x transforms to y = cos (kx)

k > 1 ; a horizontal shrink occurs
0 < k < 1 ; a horizontal stretch occurs

y = cos x transforms to y = A cos x

|A| > 1 ; a vertical stretch occurs
|A| < 1 ; a vertical shrink occurs
