Answer:
The answers would be 9 and 1.
Step-by-step explanation:
x= 5±√16 can be separated into two equations.
x=5+√16 and x=5-√16
1. 5+√16 can be solved by simplify √16, which is 4. So then it would become 5+4 which equals 9.
2. 5-√16 can be solved by simplifying √16 which is 4. So then it would become 5-4 which equals 1.
So the values of x are 9 and 1.
Plugging in (2,-7) into
y=-5x+b, we get that b=3.
Therefore, the equation is y=-5x+3
The value of c is 233.3
Step-by-step explanation:
Given equation is:

To find the value of c, we have to isolate c on one side of the equation
So,
Adding 250 on both sides

Multiplying by 20 on both sides

Dividing both sides by 18

Rounding off to the nearest one decimal place
c=233.3
The value of c is 233.3
