Answer:
Sample response: Using the distributive property to expand the first expression, you would get -1.5x - 2.5. Since the constant term does not have the same sign as the second expression, the two expressions are not equivalent. Also, if you substitute in a value for x and evaluate each expression, the values will not be equal.
Step-by-step explanation:
It's the simple response
Answer:
As x approaches ∞, y approaches -∞
As x approaches -∞, y approaches ∞
Step-by-step explanation:
![f(x) = -x^5 + 9x^4 - 18x^3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-x%5E5%20%2B%209x%5E4%20-%2018x%5E3)
F(x) is a fifth degree (odd function ) with negative leading coefficient
If exponent is odd and leading coefficient is negative then end behavior is
As x approaches ∞, y approaches -∞
As you go on the right , f(x) goes down
As x approaches -∞, y approaches ∞
As you go on the left , f(x) goes up
Let x equal the # of coach tickets
Let y equal the # of first class tickets
x + y = 16
260x + 970y = 10,550
Solve and state the answer. Use the substitution method to solve this system. Solve the first equation for x.
x + y = 16
x = 16 - y
Now substitute the resulting expression into the other equation and solve for y.
260( 16 - y ) + 970y = 10,550
4160 - 260y + 970y = 10,550
Combine like terms
4160 + 710y = 10,550
Subtract 4160 from both sides
710y = 6390
divide by 710
y = 9
Substitute the value of y into the equation that we solved for x, x=17−y.
x = 17 - 9
x = 8
Therefore the answer is, 8 coach tickets and 9 first class tickets.
Answer:
A. ![y = \frac{2}{5}x -2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2%7D%7B5%7Dx%20-2)
Step-by-step explanation:
The y-intercept starts at -2
The slope is
because it goes up 2 and 5 to the right.
The equation would be ![y = \frac{2}{5}x -2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2%7D%7B5%7Dx%20-2)
Step-by-step explanation:
here is your answer bro..just use the formula and keep the value
