Answer:
Step-by-step explanation:
there are function that "invert" each other..
subtraction inverts addition...
3+2 = 5 ... 5-2 = 3
division inverts multiplication
5*2 = 10 ... 10/2 = 5
Using that concept, "factoring" is basically the inverse of multiplication
3x^2 + 9x can be factored to 3x(x+3)
if you multiply that out it reverts back to the original equation
so x^2 + 5x + 6 factors to (x+3)(x+2)
if you multiply that out (foil it)
you get x^2 + 5x + 6
Answer:
905
Step-by-step explanation:
365+540=905
Answer:
92
Step-by-step explanation:
Let the number be x.
As per the question,
3/4x - 18 = 1/2x + 5
(4)3/4x - (4)18 = (4)1/2x + (4)5
3x - 72 = 2x + 20
x = 92
The number is 92.
Answer:
C
Step-by-step explanation:
If the object figure was reflected along the y-axis, it would've ended up on the third quadrant (meaning the region of the graph where the x and y values are both negative). Moving the image down 2 units would cause it to be at a lower level than the image of M'.
The rest of the options are all correct.
Answer:
v =7/75
Step-by-step explanation:
5/3v = 125/7
cross multiply
5*7 = 125 *3v
35 = 375v divide by 375
v = 35/375
v =7/75
