Answer:121
Step-by-step explanation:
In order to eliminate the y terms, the y terms must be reciprocals.
The first equation has 9y.
To eliminate y, you need to add to it -9y.
The second equation has y. In order for the second equation to have -9y, you must multiply both sides of the second equation by -9.
Answer: D -9
Answer:
200 m s^-2.
133.33 ms^-2.
100 m s^-2.
Step-by-step explanation:
Use Newton's Second Law of motion:
Force = mass * acceleration
The force is in Newtons so the mass must be in kilograms#
100 g = 0.1 kg. So:
20 = 0.1 * a
a = 20/ 0.1 = 200 m s^-2.
We calculate the acceleration for the 150g and 200g potato in the same way.
For the first Q the answer is the first square on the left 10 miles divided by 12 hours = 0,83 miles
And the second Q goes with the last square 12 hours divided by 10 miles = 1.2 h which in minutes is 72 minutes or 1h and 12 minutes.
Answer:
The y intercept and the slope are given in the equation. y=mx+b is slope-intercept form. mx is the slope and b is the y intercept. so in y=3x-5, 3x is the slope and -5 is the y intercept (what y is when x is zero).
