Answer: D
<u>Step-by-step explanation:</u>
Vertex form is: f(x) = a(x - h)² + k where (h, k) is the vertex.
f(x) = (x - 3)² - 5
- the vertex is (3, 5).
- "a" is positive (+1), so it points upward.
The only graph that matches is the last one, <em>which I called graph D.</em>
Answer:
3x - y + 
Step-by-step explanation:
Hooboy okay here we go.
1.) Rewrite the equation in the classic division method
3x³ + 2x²y - xy² 
2.) Divide using normal division rules, but it's super hard now 'cause there are letters involved. Basically, what can you multiply 3x³ by to get 9x⁴? 3x. So 3x is your first number. Then multiply everything else by 3x, and subtract
3x
3x³ + 2x²y - xy² 
-(9x⁴ + 6x³y - 3x²y²)
= 0 - 3x³y - 2x²y² - 5x²y + xy³
Now lets do that again, see what happens. 3x³ times -y should get -3x³y
3x - y
3x³ + 2x²y - xy² 
- (9x⁴ + 6x³y - 3x²y²)
= 0 - 3x³y - 2x²y² - 5x²y + xy³
- ( - 3x³y - 2x²y² + xy³)
= 0 + 0 - 5x²y + 0
So! From this information, we can know that the answer is 3x-y with a remainder of - 5x²y. How it's written is shown above, in "Answer"
To find the cost per pound you simply divide the amount paid by the amount purchased
For Beef it would be:
$7.20 ÷ 2.0 = $3.60
For Pork it would be:
$8.10 ÷ 2.5 = $3.40
For Chicken it would be:
$9.80 ÷ 3.5 = $2.8
Any whole number above 5600, not counting 5600.
the number 5600 would make them equal, but it needs to be greater than. so any whole number above 5600 would make the statement true:
800(7)= 5600
5600 / 7 = 800
so,
5601 / 7 > 800 is a true statement
again, any whole number above 5600 is a correct answer, there are an infinite amount of solutions
Answer:

Step-by-step explanation:
Simply equate the equations:
-2x+7=5x-7
14=7x

Put this in one of the equations again.
$ y=-2(2)+7$
$\implies y=-4+7= \boxed{3}$
