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
Answer:
100 students play only basketball.
Step-by-step explanation:
We are given the following information in the question:
Total number of students in school = 240
Number of students that play soccer =
n(S) =80
Formula:
Putting the values, we get,
Thus, 144 students play basketball.
Out of these 144, 44 plays soccer as well.
Thus, 100 students play only basketball and not soccer.
Sandy got 350 out of 2400.
Her portion is 350/2400 which can be reduced to:
35/240 = 7/48
The portion is 7/48
Hello,
(3x²+5x-8)+(5x²-13x-5);
3x²+5x²+5x-13x-8-5;
You add up similar terms, you get it:
(3+5)x²+(5-13)x+(-8-5);
8x²-8x-13
Bye:-)
Answer:
Absolutely, I would be more than willing to.
