Answer:
x = 4.31 and y = -1.23 (to the nearest hundredth).
Step-by-step explanation:
y = 16 - 4x
3x + 4y = 8
Substitute y = 16 - 4x in the second equation:-
3x + 4(16 - 4x) = 8
3x + 64 - 16x = 8
-13x = 8 - 64 = -56
x = -56 / -1 3 = 4.308
Plugging this value into the first equation:-
y = 16 - 4(4.308)
= -1.23
The answer is 39600
Use calculator to evaluate it
8!-3!(5!) = 39600
Or
8!=1×2×3×4×5×6×7×8
3!=1×2×3
5!=1×2×3×4×5
Solve it this way by replacing 8!, 3! and 5!
Answer is B I did it on one of my quiz
A or C cause they both have the same equation that start from a + but descend down to a -
