Answer:
He was incorrect
Step-by-step explanation:
3x+5(3x+6)
multiply whats inside the parenthesis by whats outside
3x+15+30
he forgot to multiply 6x5 too.
If it’s in slope intercept I pretty sure the slope should be 5 because if y=mx+b and the m is slope then slope should be 5
(4x - y)/(2y + x) when x = 3 and y = 3 is
(4(3) - 3)/(2(3) + 3) = (12 - 3)/(6 + 3) = 9/9 = 1
Answer:
30
Step-by-step explanation:
The midpoint of BC will be a distance from line k that is the average of the distances of B and C: (17+13)/2 = 15. Call that midpoint P. We know distance MP is half of distance MA. This same relationship will hold with respect to the distances from P and A to any line through M. That is, the distance from line k (through M) is twice the distance from P to line k: 30 units.
Step-by-step explanation:
0.5 ( r + 2.75 ) = 3
r + 2.75 = 3 / 0.5
r + 2.75 = 6
r = 6 - 2.75
r = 3.25
