The answer is the 3rd choice. The beginning temperature is -9 so you add the 7 to the -9 degrees to find the temperature at noon because it increased.
Answer:
Step-by-step explanation:
2.5 = 5 * .5
1 = 1
70 = 2 * 5 * 7
LCM = 2 * 5 * 7
If you include the 1/2, you will reduce the LCM to 35, but 70 will be left out of the LCM.
Discussion
The discriminate is b^2 - 4*a*c
The general equation for a quadratic is ax^2 + bx + c
In this equation's case
a = 1
b= -5
c = - 3
Solve
(-5)^2 - 4*(1)*(-3)
25 - (-12)
25 + 12
37
Note
Since the discriminate is > 0, the roots are real and different. The roots do exist and there are 2 of them.
Answer:
a) max 12000 , min 0
b) no solution
c) pricing based on profit
Step-by-step explanation:
a) look at the parabola
b) there is more than one x (0)
c) the y intercepts represent his profit based on how much he priced the items at
Answer:
The answer is B
Step-by-step explanation: After solving this equation using y=mx+b
I got y=-4x+7
So they give us the slope which is negative 4
so you would throw in the x coordinate with the slope and multiply to get y=-12+7
then you would use the y coordinate to substitute the Y
-5=-12+7
i add twelve on both sides and end up with the y intercept being 7]
so I add them into the equation and got y=-4x+7
