Answer:
(d) 2x +y = 8
Step-by-step explanation:
The answer choices are shown in "standard form," so the comparison to the given equation is easier if it is written in standard form. Add 2x to both sides:
2x +y = 5 . . . . . . given equation in standard form
The other equation in a system with no solution will look like this, but will have a different constant:
2x +y = 8 . . . . . . does not intersect the given equation
_____
<em>Additional comment</em>
All of the other equations shown will intersect the given equation. One way to show this is to use the given equation to substitute for y in the answer choices:
a: 2x -(-2x+5) = 8 ⇒ 6x -5 = 8 . . . one solution: x=13/6
b: x +2(-2x+5) = 8 ⇒ -3x +10 = 8 . . . one solution: x=2/3
c: x -2(-2x+5) = 8 ⇒ 5x -10 = 8 . . . one solution: x=18/5
d: 2x +(-2x+5) = 8 ⇒ 5 = 8 . . . no solution
It dropped by 4.5 means that we have to subtract 4.5 from 9.2
9.2 - 4.5 = 4.7 °C
So 4.7 °C is your answer :D
Heads heads
Heads tails
Tails heads
Tails tails
There are four possibilities. There is only one where heads happens twice; therefore, the probability is 1/4, or 25%. I hope I helped! ^u^
Answer:
a) 10,61
Step-by-step explanation:
31/3 = 10,33333...
2/7 = 0,28571428...
10,33 + 0,28 = 10,61
The answer is B, 7i.
sqrt(-49)
Pull out an i.
i*sqrt(49)
Take the square root to get 7i.
