Answer:
72
Step-by-step explanation:
12 times 6 is 72
48 + 24 =72
<span>Simplifying
5x2 + -35 = 0
Reorder the terms:
-35 + 5x2 = 0
Solving
-35 + 5x2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '35' to each side of the equation.
-35 + 35 + 5x2 = 0 + 35
Combine like terms: -35 + 35 = 0
0 + 5x2 = 0 + 35
5x2 = 0 + 35
Combine like terms: 0 + 35 = 35
5x2 = 35
Divide each side by '5'.
x2 = 7
Simplifying
x2 = 7
Take the square root of each side:
x = {-2.645751311, 2.645751311}</span>
Answer:
B
Step-by-step explanation:
The standard form of a circle is
where h and k are the coordinates of the center of the circle and the radius is squared. The radius is easy...take the square root of 25 to get that the radius is 5. Since the pattern for the standard form is "x-" and "y-", if (x+2)^2 is the horizontal placement of the center, it actually was originally written as (x-(-2))^2, so the h coordinate is -2. Same goes for the vertical movement of the center. (y-(5))^2 means that the k coordinate is a positive 5.
Answer:
a) 8 < 9 < 10 1/2
b) 10 1/2 > 9 > 8
Step-by-step explanation:
We can use inequalities to order shoe sizes. We need to know what the symbols mean, for example < means "is lower than" while > means "is greater than". We know that 8 is lower than 9, and 9 is lower than 10 1/2 (which can be written also as 10.5), so we can write:
a) 8 < 9 < 10 1/2
The other way around would be to say that 10 1/2 is greater than 9, and 9 is greater than 8, which means:
b) 10 1/2 > 9 > 8
Hey there! :D
So I want you to think of a function as an input and output, where f(x)= y and x=x.
(x,y)
(0.4, 0.2)
So when 0.4 is equal to x, y is equal to 0.2.
So, you can plug in the point you do know.
(1.6, y)
Divide x by 0.4.
1.6/0.4= 4
0.2*4= 0.8
f(x)= <em>.8 </em><em>
</em>
I don't know if you added another 0 to the decimal, but the function is set up so that f(x) is half of x. 1.6/2=.8 That is the answer.
I hope this helps!
