I need help plsssss asap
Lunna [17]

Answer:

D) (0,9.5) and (10,1.5)

Step-by-step explanation:

a line of best fit is a line that is drawn through the data points on the scatter plot. Option D is the only answer that draws a linear line through the data points.

Option A makes a short line above the points. if the line is not through the points, it doesn't work

Option B is drawing a positive line (as in it's increasing) and therefore cannot work

Option C draws a line below the points and does not represent the line of best fit for this scatter plot

Math is annoying! Can someone help me please?
lord [1]
16.  would be C since they both consist of the same variable to the same power

17. x-2x+7-9+4x
     c. 3x-2
18. -4(3a-5). You would multiply -4 by 3 a, and -4 by -5. It turns to
      -4(3a)-4(-5)
     a. -12a+20

“Solve the system using elimination” im not good at math so can someone help me
iris [78.8K]

Answer:

No solutions

Step-by-step explanation:

i did this via substitution so i hope it isn't a problem

3x+y=4

6x+2y=−4

Step: Solve 3x+y=4for y:

3x+y+−3x=4+−3x(Add -3x to both sides)

y=−3x+4

Step: Substitute−3x+4foryin6x+2y=−4:

6x+2y=−4

6x+2(−3x+4)=−4

8=−4(Simplify both sides of the equation)

8+−8=−4+−8(Add -8 to both sides)

0=−12

so there are no solutions

hope this helps!!
