Answer:
23
Step-by-step explanation:
(4 x 23) -20 = 72
Answer:
Your answer is -6 over 15
Step-by-step explanation:
Use the formula y2-y1 over x2- x1 to solve the slope. Then plug in your numbers. It would be 1- 7 over 10 - (-5). This equals -6/15, which would be the slope.
Answer
Find out the what is the acceleration of the object .
To prove
Formula

Where
t = the time in which the change occurs
As given
If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s .
Final velocity = 98 m/s
Intial velocity = 65 m/s
Time = 12 s
Put in the formula


Acceleration = 2 .75 m/s ²
Option (A) is correct .

Step-by-step explanation:
Comment
If 4 numbers have an average of 9, then total of the 4 numbers is 4 * 9 = 36.
If one of the 4 numbers is a 7, then
7 + x = 36 where x is the sum of the other 3 numbers.
7 + x = 36 Subtract 7 from both sides
7- 7 +x = 36 - 7
x = 29
