Answer:
-35
Step-by-step explanation:
15(x-7) + 4 = 10(x-7) +4
15x + 105 + 4 = 10x -70 + 4
15x + 109 = 10x - 66
-10x + 109 = -66
5x+ 109 = -66
-109 = -109
5x = -175
divide -175 by 5
Answer:
10
Step-by-step explanation:
Firstly, find the value of f(3)
⇒ [sub in 3]
⇒ [multiply by 2 and add 1]
Now, find g(f(3))
⇒ [sub in 7]
⇒ [multiply by 3 and subtract 1]
⇒ [divide by 2]
Step-by-step explanation:
845/1160 = 0.728
116.5/174 = 0.669
42.25/58 = 0.728
23.4/29 = 0.806
16.9/23.2 = 0.728
25.35/34.8 = 0.728
Hence the 2nd, 4th and 5th options are correct.
Answer:
(1.63,4.18)
Step-by-step explanation:
1) look at the graph below: they intersect at about (1.5,4)
lets solve the systems by substitution:
since both equations are equal to y lets substitute the second equation into the first:
-6x+14=5x-4
-6x-5x=-14-4
-11x=-18
x=1.63
lets substitute x in the first equation:
5(1.63)-4=4.18
