Answer:
n = 7m
Step-by-step explanation:
n = k(m)
21 = k(3)
k = 21/3 = 7
n = 7m
80/100 and 8/10 cause if you multiply the 8/10 by2 ( numerator and denominator) you see that your equivalent fraction is 80/100
Answer:
+9.
Step-by-step explanation:
6 / 2 = 3
3^2 = 9
So it is + 9
Checking:
(x + 3)^2 = x^2 + 6x + 9.
(-24,-2)(-15,-8)
slope = ( - 8 - (-2) / (-15 - (-24) = (-8 + 2) / (-15 + 24) = -6/9 = - 2/3
y = mx + b
slope(m) = -2/3
use any of ur points (-24,-2)...x = -24 and y = -2
now we sub and find b, the y int.
-2 = -2/3(-24) + b
-2 = 16 + b
-2 - 16 = b
-18 = b
so ur equation is : y = -2/3x - 18
now in y = mx + b form, the y int is in the b position
y = mx + b
y = -2/3x - 18
so ur y intercept is -18 or (0,-18) <=====
to find the x int, sub in 0 for y and solve for x
y = -2/3x - 18
0 = -2/3x - 18
2/3x = -18
x = -18 * 3/2
x = - 54/2 = -27....and ur x intercept is -27 or (-27,0) <===
