Answer:

<h2>B. y=25x+50</h2>

Step-by-step explanation:

We need to use two points on the line: (0,50) and (2,100).

Then, we find the slope with the formula

m=\frac{y_{2}-y_{1}  }{x_{2} -x_{1} }\\ m=\frac{100-50}{2-0}=\frac{50}{2}=25

Then, we use the point-slope formula to find the equation

y-y_{1} =m(x-x_{1} )\\y-50=25(x-0)\\y=25x+50

Therefore, the right answer is B.

Find the quotient of 812.30 divided by 83. Round to the nearest tenth.
elena-14-01-66 [18.8K]
812.30/83 = 9.78674698.....
Nearest tenth means one number under decimal place so...

812.30/83 ~ 9.8

Explanation: The 9.7... rounded up to 9.8 because the number after the tenths place (in this case the number after the 7) is greater or equal to 5.

Not to be mean Fernanda but it wouldn't be 0 it actually would be 0.19444444 so I would just put 0.194 and put a line over the 4 to show that it repeats continuously
