Answer:
t = -17/49
Step-by-step explanation:
25t-13=-24t-30
Add 24t to each side
25t+24t-13=-24t+24t-30
49t-13=-30
Add 13 to each side
49t-13+13=-30+13
49t = -17
Divide each side by 49
49t/49 = -17/49
t = -17/49
Answer:
B. y=1/2x-5
Step-by-step explanation:
From the graph, we read the slope of line JK.
slope = rise/run = -3/-6 = 1/2
The equation we need has the same slope.
y = mx + b
y = (1/2)x + b
It passes through point P(6, -2). Now we find b.
-2 = (1/2)(6) + b
-2 = 3 + b
b = -5
The equation is
y = (1/2)x - 5
Set it up as a ratio. $5.25/5 = $1.05 per notebook
Then solve your equation by multiplying the cost by 3. 3 * $1.05 = $3.15
