Answer: 625100

Step-by-step explanation:

To begin, we would start multiply both numbers one by one.

(6.3 x 10^6) - 4.9 x 10^4

6.3 x 10^6 = 6300000

4.9 x 10^4 = 49000

Now, subtract (6.3 x 10^6) and (4.9 x 10^4)

                          6300000.            49000

6300000 - 49000 = 6251000

Write an equation that is perpendicular to and 3x+y=3 whose y-intercept 5. Anyone please help me, no link just explain how to do
Liula [17]

Answer:

y = \frac{1}{3}x + 5

Step-by-step explanation:

By definition, two lines are perpendicular if and only if their slopes are negative reciprocals of each other:  m = - \frac{1}{m_{2} }, or equivalently, m_{1} * m_{2} = -1.

Given our linear equation  3x + y = 3  (or y = -3x + 3):

We can find the equation of the line (with a y-intercept of 5) that is perpendicular to y = -3x + 3 by determining the negative reciprocal of its slope, -3, which is \frac{1}{3}.

To test whether this is correct, we can take first slope,  m_{1} = -3,  and multiply it with the negative reciprocal slope m_{2} = \frac{1}{3} :

m_{1} * m_{2} = -1

-3 * \frac{1}{3}  = -1

Therefore, we came up with the correct slope for the other line, which is  \frac{1}{3}.

Finally, the y-intercept is given by (0, 5). Therefore, the equation of the line that is perpendicular to 3x + y = 3 is:

y = \frac{1}{3}x + 5

Need help with my math homework 3x +2y = 8
professor190 [17]

3x=8-2y

x=(8-2y)/3

3(8-2y)+2y=8

24-6y+2y=8

-4y=-16

y=4

3x+2(4)=8

3x+8=8

3x=0

x=0

3(0)+2(4)=8

x=0,y=4
