The slope is the rate of change on a line.
If you just mean the product of the prime factors of 39 then this is the answer
39 = 3 x 13
Answer:
(-2/17, 5/17)
Step-by-step explanation:
Given the coordinates A (-3,-5) to B (9,4), we are to find the coordinate of the point cutting the line using the ratio 7:10
Using the midpoint formula;
M(X,Y) = {(ax1+bx2/a+b, (ay1+by2/a+b))
Given
x1 = -3, y1 = -5, x2 = 9, y2 = 4, a = 7 and b = 10
get the required coordinates;
X = ax1+bx2/a+b
X = 7(-3)+10(9)/7+10
X = -21+19/17
X = -2/17
Get the Y coordinate;
Y = ay1+by2/a+b
Y = 7(-5)+10(4)/7+10
Y = -35+40/17
Y = 5/17
Hence the required coordinate is (-2/17, 5/17)
Answer:
Option A
Step-by-step explanation:
Let's denote:
x is the number of albums Teresa downloads.
y is the number of individual songs Teresa downloads.
=> 9x + y = 25
Let's check:
Option A: x = 2 and y = 7 => 9 x (2) + 7 = 18 + 7 = 25 => valid
Option B: x = 1 and y = 8 => 9 x (1) + 8 = 9 + 8 = 17 => invalid
Option C: x = 4 and y = 5 => 9 x (4) + 5 = 36 + 5 = 41 => invalid
Option D: x = 3 and y = 6 => 9 x (3) + 6 = 27 + 6 = 33 => invalid
