There are 52 weeks in a year, so 52x represents how much she earns in a year.
Answer:
x=-5, y=-2. (-5, -2).
Step-by-step explanation:
x-3y=1
-x+6y=-7
-------------
3y=-6
y=-6/3
y=-2
x-3(-2)=1
x+6=1
x=1-6
x=-5
1/4 = the probability of getting spiral wrapping paper
1/3 = the probability of getting a green ribbon
1/4 x 1/3 = 1/12 = the probability of getting spiral wrapping paper and a green ribbon
Answer:
C and D
Step-by-step explanation:
To determine which pairs are solutions, substitute the coordinates into the left side of the equation and if equal to the right side then they are solutions.
(7, - 2)
2(7) + 10(- 2) = 14 - 20 = - 6 ≠ 12 → (7, - 2) is not a solution
(- 5, - 4)
2(- 5) + 10(- 4) = - 10 - 40 = - 50 ≠ 12 → (- 5, - 4) is not a solution
(4,
)
2(4) + 10(
) = 8 + 4 = 12 → hence solution
(- 5,
)
2(- 5) + 10(
) = - 10 + 22 = 12 → hence solution
Answer:
Step-by-step explanation:
Neither blue plot line is dashed, so we eliminate any equation that contains the symbols "<" or ">". Remove A and C
B and D (actually all options) have y ≤ -x + 4 which is a line with slope -1 any y intercept 4. This represents the area below the line running from (0, 4) to (4, 0)
Which leaves us to select from y ≥ x + 2 for option B or y ≤ x + 2 for option D
As the shaded area is <em>below</em> the line we choose <u>option D</u>
