Answer:
See explanation below
Step-by-step explanation:
a. One solution (p = 1/4)
b. Infinite amount of solutions (No matter what value for p is, the equation will always be 7=7)
c. One solution (p = 12)
d. No solution (No matter what value for p is, the equation will always be 3 = -1, which wouldn't work)
Answer:
-3
Step-by-step explanation:
Slope is rise over run or the change in y over the change in x
the answer is -3 over 1
Answer:
3 hours
Step-by-step explanation:
let x = # of hours
Amy: y = 25 + 15x
Dan: y = 10 + 20x
Set the expressions equal to each other and solve for x
10 + 20x = 25 + 15x
20x = 15 + 15x
5x = 15
x = 3
I think y = 8. Since x = -3 then the equation would be y = -1(-3) +5. -1 times -3 equals 3. So now the equation is y = 3 +5. That would give you 8.
