Answer:
n = -28
Step-by-step explanation:
-4 = 10 + n/2
first step, subtract 10 from each side to get:
-14 = n/2
cross-multiply to get:
n = -28
Answer: 90%
Step-by-step explanation:
Answer:
x ≥ -2 AND y < 2x
Step-by-step explanation:
the equation for the vertical line is x = -2
the inequality crosses the y-axis at 0 and it's slope is 2 because if you are at the point (-2,-4) you must go up by 4 and then to the right by 2 which reduces to 2
we can write the equation now as:
y = 2x
the shaded portion indicates the solutions to both of these equations so we can say that:
all values that are greater than or equal to -2 AND values less than y=2x
Y=50-3.25X after 12 lunches it would have a value of 11$
