Answer:
D
Step-by-step explanation:
If we look at the right side of the equation we see that the y-intercept is 2, so we will place a point on (0,2).
Next, we look to see if the slope of the graph if positive or negetive, and to see what is the slope (2x).
Finally, we look at the inequality if it is greater than (>), less than (<), greater than or equal to (_>), or less than or equal to (<_).
*Note the following:
if < then the line is dotted and the shading will be under the line.
if > then the line is dotted and the shading will be above the line.
if <_ then the line is solid and the shading will be under the line.
if _> then the line is solid and the shading will be above the line.*
It is a lot of information if you look at it, but with practice it can be made easier.
This is a lot of math to write.... so I'll just say the answer is -21 :D
You can see that the term
appears in both equations. In this cases, we can leverage this peculiarity and subtract the two equations to get rid of the repeated term. So, if we subtract the first equation from the second, we have
![(-4x -6y) - (-10x-6y) = 54-0 \iff 6x = 54 \iff x = 9](https://tex.z-dn.net/?f=%20%28-4x%20-6y%29%20-%20%28-10x-6y%29%20%3D%2054-0%20%5Ciff%206x%20%3D%2054%20%5Ciff%20x%20%3D%209%20)
Now that we know the value of
, we can substitute in any of the equation to deduce the value of
: if we use the first equation, for example, we have
![-10x-6y=0 \iff -10\cdot 9 - 6y = 0 \iff -90-6y=0 \iff 6y = -90 \iff y = -15](https://tex.z-dn.net/?f=%20-10x-6y%3D0%20%5Ciff%20-10%5Ccdot%209%20-%206y%20%3D%200%20%5Ciff%20-90-6y%3D0%20%5Ciff%206y%20%3D%20-90%20%5Ciff%20y%20%3D%20-15%20)
Answer:
It would take 13.7142857 or 13.7, in better terms about 14 minutes.
Step-by-step explanation:
48/14 = 3.42857143
3.42857143 x 4 = 13.7142857 or 13.7.
