Answer:the third option is correct
Step-by-step explanation:
The system of equations are
y = 2x^2 - 5x - 7 - - - - - - - - - - -1
y = 2x + 2 - - - - - - - - - - - - - 2
We would equate equation 1 and equation 2. It becomes
2x^2 - 5x - 7 = 2x + 2
2x^2 - 5x - 2x - 7 - 2 = 0
2x^2 - 7x - 9 = 0
We would find two numbers such that their sum or difference is -7x and their product is - 18x^2. The two numbers are 2x and - 9x. Therefore
2x^2 + 2x - 9x - 9 = 0
2x(x + 1) - 9(x + 1) = 0
2x - 9 = 0 or x + 1 = 0
2x = 9 or x = - 1
x = 9/2 = 4.5
Substituting x = 4.5 or x = -1 into equation 2, it becomes
y = 2 × 4.5 + 2 or y = 2 × - 1 + 2
y = 11 or y = 0
Therefore, the solutions are
(4.5, 11) (- 1, 0)
The answer is 45 total.
So Tommy is 22 years old while his Father is 45.
45 years of age total, tommy is 23 years younger so 45 - 23 = 22 so tommy is 22 while his father is 45.
Answer:
Answer is B
Step-by-step explanation:
This is because there were 14 chocolate cupcakes to 21 vanilla cupcakes which in ratio form is 14 to 21 and simplified is 2 to 3
Since lean beef has 2 legs and there is 18 legs in total, there are 9 lean beef cows.
20 - 9 = 11
There is 11 more ground beefs than lean beefs.
Hope this helps
