Answer:
10.5.
Step-by-step explanation:
By similar triangles:
IJ / 21 = 8 /(8+8) = 1/2
IJ / 21 = 1/2
IJ = 1/2 * 21
= 10.5.
Answer:
3 and i use flvs too, also that pfp is fire
Step-by-step explanation:
(2,3)(4,4)
slope = (4 - 3) / (4 - 2) = 1/2
y = mx + b
slope(m) = 1/2
(2,3)...x = 2 and y = 3
sub and find b, the y int
3 = 1/2(2) + b
3 = 1 + b
3 - 1 = b
2 = b
ur equation is : y = 1/2x + 2...but we need it in standard form
y = 1/2x + 2
-1/2x + y = 2 ...multiply by -2
x - 2y = -4 <== standard form
The answer is 4x that the answer
