Answer:
72.1 and -48.1
Step-by-step explanation:
I set up the equations x + y = 24 and x*y=-3468. Then I substituted for y and used the quadratic formula to come to two numbers rounded to about 72.1 and -48.1. Hope that helps :)
Answer:
7x + 5y ≥ 400
Step-by-step explanation:
Given:
Swimming burns = 7 calories per minute
Yoga burns = 5 calories per minute
At least calories burn = 400
Total minutes of swimming = x
Total minutes of yoga = y
Find:
Inequality
Computation:
7 calories per minute(Total minutes of swimming) + 5 (Total minutes of yoga) ≥ 400
7x + 5y ≥ 400
1) First you would multiply 3 × -4 which gives you -12
You add exponents when multiplying.
So, x^2 +x^3 = x^5 and y^3 +y^4 = y^7
Final Answer: -12x^5y^7
2) 7 times 4 is 28 and y^3 +y^5 = y^8
Final Answer: 28y^8
