C: as x increases, y increases, then y decreases, then y increases again.
Y = x - 7
2x + y = 8
2x + (x - 7) = 8
2x + x - 7 = 8
3x - 7 = 8
<u> + 7 + 7</u>
<u>3x</u> = <u>15</u>
3 3
x = 5
y = x - 7
y = 5 - 7
y = -2
(x, y) = (5, -2)
Answer:
2 / 5
Step-by-step explanation:
Fractions are written in the form part/whole, in this case, the part is 18 and the whole is 45 so the fraction would be 18 / 45 which simplifies to 2 / 5.
Answer:
4 r^3
Step-by-step explanation:
sqrt ( 16 r^6 ) = sqrt ( 4^2 * (r^3)^2 ) = 4 r^3
Answer:
Option B
Step-by-step explanation:
Let 'x' represents the number of miles traveled and 'y' represents the total cost of of the taxi ride.
Cost of ride with a rate of $2.25 per mile = $2.25x
Since, service charge of the taxi = $3 for first mile
Total cost of the ride = 2.25x + 3
Equation for the cost of the ride will be,
y = 2.25x + 3
Since, farthest distance that the taxi can travel = 35 miles
That means value of x may vary between x = 0 to x = 35 (including x = 25)
Therefore, domain for the situation will be,
0 < x ≤ 35
Option B will be the answer.
