86. To find that you just add up the two given angles and subtract that by 180. All triangles angles add up to 180 degrees.
What you said doesn't even make sense.
I'll assume you said f(x) = -5x^2 + 4.
This is an even function.
f(-x) = f(x)
The total cost of 1000 CD's given that each costs $6.45 is equal to $6450. The revenue is the product of the number of CD's sold, n, and the selling price of each is $12.95. The equation for the profit or loss of "CD Universe" is, P = 12.95n - 6450
Answer:
A) 6x + 6y = 24, Yes, they have the same solution set
Step-by-step explanation:
Let's first start by multiplying the equation by 3:
(2*3)x + (2*3)y = 24
6x + 6y = 24
Now lets find the solution set for both:
6y = -6x + 24
y = -x +4
2y = -2x + 8
y = -x +4
Yes, they have the same solution set
Answer:
1. 2x
2. v(t) =2
3. 24mph
Step-by-step explanation:
1. W(t) = x^2 -3
dw/dt = 2x dx/dt
2. v(t) =2
Take the derivative to get the acceleration
dv/dt = 0
The choice you picked has 0 velocity so it is not in motion
3. To find the velocity
