Answer:
2/3
Step-by-step explanation:
To find the slope solve the equation in the form of y=mx+b.
4x-6y=18
-6y= -4x+18
y= 2/3x-3
The slope is 2/3.
Answer:
28.
Step-by-step explanation:
9x^2 + 2 = 10x
9x^2 - 10x + 2 = 0
The discriminant is b^2 - 4ac.
In this case, a = 9, b = -10, and c = 2.
(-10)^2 - 4 * 9 * 2
= 100 - 36 * 2
= 100 - 72
= 28.
Since the discriminant is positive, there are two real solutions to the function.
Hope this helps!
Amanda needs to spend more than 8 minutes on Routine 1 to burn more calories.
Step-by-step explanation:
Given,
Calories burned in Routine 1 = 15.5 calories per minute
Let,
t represents the number of minutes spent running.
Total calories burned = T
T = 15.5t Eqn 1
Calories burned in Routine 2 = 22 calories walking + 12.75 per minute
T = 12.75t + 22 Eqn 2
For burning more calories in Routine 1;
Eqn 1 > Eqn 2
![15.5t>12.75t+22\\15.5t-12.75>22\\2.75t>22](https://tex.z-dn.net/?f=15.5t%3E12.75t%2B22%5C%5C15.5t-12.75%3E22%5C%5C2.75t%3E22)
Dividing both sides by 2.75
![\frac{2.75t}{2.75}>\frac{22}{2.75}\\t>8](https://tex.z-dn.net/?f=%5Cfrac%7B2.75t%7D%7B2.75%7D%3E%5Cfrac%7B22%7D%7B2.75%7D%5C%5Ct%3E8)
