Answer:
option D
Step-by-step explanation:
x-2y≥-12
-2y≥-x-12
y≤0.5x+6
has to be a solid line since y is less than or equal to 0.5x+6
so, options 1 and 3 are not applicable
also, in y≤0.5x+6 , y is less than or equal to this line, thus it only exists on the line and to the right of it (below it)
so, option 2 is wrong also, leaving us with option 4 or D, which in this case is the answer

Answer:
90°
Step-by-step explanation:
Well, you are trying to simplify the numbers and the equation. You are trying to get the smallest possible number or solution. A difference between the two is that polynomials have factors and variables. Numbers are just numbers. With a polynomial, you have to combine like terms and try to reduce the length of the equation. You may not always fully solve a polynomial. With numbers, you probably will get an exact numeral answer.
So we are just solving for R?
d = rt
d/t = rt/t
d/t = r
Simply isolate the r to one side, using the principle "what you do to one side, you must do to the other."
ANSWER: r = d/t
( d divided by t)
Hope this helps!! God bless! :)
Answer:
x = 2, y = - 1
Step-by-step explanation:
Given the 2 equations
y = - 7x + 13 → (1)
y = - 1 → (2)
Substitute y = - 7x + 13 into (2)
- 7x + 13 = - 1 ( subtract 13 from both sides )
- 7x = - 14 ( divide both sides by - 7 )
x = 2
y = - 1 is already given in (2)
Then x = 2, y = - 1
