Divide by 21 to put the equation in intercept form.
x/(21/9) + y/(-21/7) = 1
x/(7/3) + y/(-3) = 1
The x-intercept is (7/3, 0)
The y-intercept is (0, -3)
The 3rd choice is appropriate.
Let gradient of original line = m = 1/6
Gradient of line perpendicular to this = -1/m = -6
(Gradient = slope)
Answer:
36
Step-by-step explanation:
13) divide 71.5 by 5.5 to find the answer for u.
14) find the common denominator then divide like in the last one
15) multiply 11 by 44 to find t
16) multiply 14 by 8.3 to find b
17) multiply 3 by 15 to find x
18) divide 23.4 by 7.8 to find x
