Answer:
A = 3
B = 1
C = 2
D = 10
E = 2
F = Not listed
G = 1
Step-by-step explanation:
![\sqrt[3]{270x^5y^7} =\sqrt[3]{27*10x^5y^7}=3xy^2\sqrt[3]{10x^2y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B270x%5E5y%5E7%7D%20%3D%5Csqrt%5B3%5D%7B27%2A10x%5E5y%5E7%7D%3D3xy%5E2%5Csqrt%5B3%5D%7B10x%5E2y%7D)
We know that
the x-intercepts of the quadratic function f(x)=x²<span>−3x−10 is when
f(x)=0
</span>x²−3x−10=0
Group terms that contain the same variable, and move the
constant to the opposite side of the equation
(x²−3x)=10
Complete the square. Remember to balance the equation
by adding the same constants to each side.
(x²−3x+2.25)=10+2.25
Rewrite as perfect squares
(x-1.5)²=12.25----------> (+/-)[x-1.5]=3.5
(+)[x-1.5]=3.5----> x1=5
(-)[x-1.5]=3.5-----> x2=-2
<span>
the answer is</span>
the x-intercepts of the quadratic function are<span>
x=5x=-2</span>
The answer would be 6 4/6 - 2 3/6 which would equal 3 1/6.
We are going to want to change any mixed number into an improper fraction. 2 3/4 is 11/4 and 1 2/5 is 7/5.
We are going to set up a proportion where the lbs are on the top and the money is on the bottom. x is going to be how much it costs for 2 3/4 lbs of lunch meat.
(7/5)/3.36 = (11/4)/x
Cross multiplication \/
7/5x = 9.24
x = 6.60
As a final answer, the 2 3/4 lbs of lunch meat cost $6.60
Answer:
$300
Step-by-step explanation:
$400 is 100% of the price
25% is a quarter of 100%
A quarter of 400 is 100 so the discount was $100
400-100 =300
