Step-by-step explanation:
(3y=9+3)(8x-6y=-4)
(3y=12)(8x-6y=-4)
(y=12÷3)(8x-6y=-4)
(y=4)(8x-6y=-4)
Now putting the value of y in (8x-6y=-4)
8x-6*4=-4
8x-24=-4
8x=24-4
8x=20
x=20/8
x=5/2
Answer:
(x - 1) x (5x + 4)
Step-by-step explanation:
5 x 2 – 4 = 6
5 x 4 – 4 = 16
6 x 2 – 11x – 4 = 56
5 x 2 – x – 4 = (x - 1) x (5x + 4)
Answer:
A) It will take john 15 months to save./////B)The slope of the graph would be steeper.
Step-by-step explanation:
A) It will take him 15 months because 300/20 is 15 and if he earns 20$ every month you multiply 15 by 20 and get 300$.So he will earn 300$ for the new Ipod in 15 months.
B)The slope would be steeper because he is earning more money in less of a time.In this case he would earn 300$ in 7 1/2 months.
