X=4

Explanation: 42-3x=30
So you subtract 42 on each side leaving you with -3x=-12 and then you divide by -3 on each side meaning -12/-3 which leaves you with x=4

Please help. question in the photo!
Alja [10]

well, if m = 1, let's see, then f(x) = √(mx) = √(1x) = √x

and then g(x) = m√x = 1√x = √x

well, if both equations are equal, then their ranges are also equal.

now, if m = "any positive real number"

f(x) = √(mx)  = √m √x will yield some value over the y-axis

g(x) = m√x will yield some range over the y-axis, however, "m" is a larger value than "√m".

what that means is that so long "m" is a positive real number, the ranges of f(x) and g(x) will be the same over an infinite range on the y-axis, even though g(x) is moving faster than f(x), f(x) is moving slower because √m makes a stretch transformation which is smaller than one "m" does.

Lindsey made a map of her town which place in Lindsey's town is located at 4,5
Nesterboy [21]

Answer:

the school

Step-by-step explanation:

the point given is (4,5) so let's try to hone in on that so to speak-

with that in mind, the way that i find the easiest to answer this is by using rise over run or the crawl before you walk method

seeing as how both are practically the same i'll just go with the craw before you walk method-

so we will 'crawl' to 4 along the x axis then we'll 'walk' and stop once we reach (4,5) and at (4,5) there is the school building and since her town is also located at the same point the school building is the correct answer

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!
