How many solutions does the equation 4x + 8 = −2 − 2 + 5x have? (1 point) Two One None Infinitely many

one

Step-by-step explanation:

only one value of x will let this equal. two would mean its exponential, none would mean the number before x would be the same on both sides but with different numbers for example 5x-8=5x+2. same 5x but when cancel them out -8 = 2 which is false. infinitely many means the two sides are identical.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
