Answer:
A. (0,2) and (7,23)
Step-by-step explanation:
To solve, we set both equations equal to each other (because both equations equal y).
3x + 2 = x^2 -4x + 2
x^2 - 7x = 0
x(x-7)
so the x values are 7 and 0.
Plugging x back into the linear equation (because it’s easier)
3(7) + 2 = 23
3(0) + 2 = 2
so the answers are (7, 23) and (0,2)
Answer:
The answer to the question is
25 % increase in production rate
Step-by-step explanation:
To solve the question, we note that
Initial number of products = 84 toy robots per day
Present production rate = 105 robots per day
The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100
Where increase in production rate = 105 - 84 = 21
Percentage increase = 21/84 ×100 = 25 % increase
Answer: C: y = 4x + 20
Step-by-step explanation:
4x is multiplying 4 by the number of levels, and you add the castles he's already found which is 4*5 =20.
First we divide 162 by 18. Our answer is 9. She earns 9$ for every hour she works. We then divide 207 by 9 and we get 23.
Answer: 23
To figure out what the number is, just do the inverse operations in the opposite order:
Start by adding 7/18 to 1 5/6, which gives you 2 2/9.
Next, multiply 2 2/9 by 1 1/5, which gives you 2 2/3.
Finally, divide 2 2/3 by 2 1/2, which gives you 1.06666...
Therefore, the number you thought of is 1.06666...
