Answer:
B) (-2, 5)
Step-by-step explanation:
Perhaps easiest is to try the points to see what works. You can also graph the equations or solve by any of several other means.
<u>Trying the points</u>
A) 3(-2)+4(-2) = -6 -8 = -14 ≠ 14
B) 3(-2) +4(5) = -6 +20 = 14; -2 = 2(5) -12 = 10 -12 . . . . true
C) 3(-4) +4(4) = -12 +16 = 4 ≠ 14
D) 3(2) +4(2) = 6 +8 = 14; 2(2) -12 = -8 ≠ -2
__
Choice B ( -2, 5) is the only point that works in both equations.
(6+18)^2 = m^2 + m^2
=> 2m^2 = (24)^2
=> m = 24/sqrt(2)
6√2 + 4 √32
try to get the same number "2" remaining under the root sign by finding what # times 2 gives 32
6√2 + 4√2×√16
since 16 is a perfect Square √16 gives 4
therefore.
6√2 + 4 ×4 √2
6√2 +16√2
these are Like terms so add them
which would give u
22√2
hoped i helped, feel free to ask any question XOX
Answer:
5x-8y
Step-by-step explanation:
4x-9y+x+y
=4x+-9y+x+y
=4x+-9y+x+y
=(4x+x)+(-9y+y)
=5x+-8y
=5x-8y
Answer:
2.5h = 150 min.
Step-by-step explanation:
An hour is 60 minutes.
A half an hour is 30 minutes.
Two hours = 1 hour + 1 hour = 60 minutes + 60 minutes = 120 minutes
2.5 hours = 2 hours + 1/2 hour = 120 minutes + 30 minutes = 150 minutes
2.5h = 150 min.
Hope this helps.
