Answer:
-5≤y≤-1
Step-by-step explanation:
The range is the values that y takes
The smallest value of y is -5 and the largest value of y is -1
-5≤y≤-1
Isolate m using inverse operations, get m by itself. (addition and subtraction, mult. and div.)
Answer:
B, D, E
Step-by-step explanation:
-8x - 6y = 10
x + 7y = 9
You can multiply any of these equations by a constant without changing the solution.
B. 4x + 3y = -10 is equivalent to multiplying each side of the first equation by -½.
D. -16x - 12y = 20 is equivalent to multiplying each side of the first equation by 2.
E. 3x + 21y = 27 is equivalent to multiplying each side of the second equation by 3.
A. -2x + 7y = 9 is wrong. The signs don't match those of the second equation.
C. 24x + 18y = 10 is wrong. The signs don't match those of the first equation.
F. x - 14y = -18 is wrong. The coefficient of x should be -2.
Answer:
B, but I can't read C
Step-by-step explanation:
the sum of any 2 sides must be longer that the 3rd.
A is not correct, 2 + 15=17, needs to be greater.
B 1, 8, 8.1 so yes as 1+8 >8.1
C 2, 8.9, I cna't tell if that last number is 9 or 92?
