The correct answers are A, D, E
Answer:
b
Step-by-step explanation:
divide both sides of the equation by 4 to leave s by itself
1.2×10‐2
Integer is a number which is not a fraction and is whole number. Yes whole numbers are 0,1,2 and so on but integer can also be negative such as -1,-2 etc.
-3⁰= -1 which is integer
18/3(is a fraction but when solved)=6 which is integer
root under49 is 7 which is integer.
some numbers which are not integer
1.2,-3.6,1/2 etc.
It depends on which variable is eliminated.
If you multiply the second equation by -1 and eliminate the y:
3x - y = 7
-6x + y = -10
-3x = -3 or x = 1
If you multiply the first equation by -2 and eliminate the x:
-6x + 2y = -14
6x - y = 10
y = -4
