-2 and 1/3 times 1 and 1/2=

Mathematics
1 answer:
torisob [31]3 years ago
4 0

Answer:

-2\frac{1}{3}\times 1\frac{1}{2}=-3.5

Step-by-step explanation:

We are asked to find the product of -2\frac{1}{3} and 1\frac{1}{2}.

Upon writing our expression as a product we will get,

-2\frac{1}{3}\times 1\frac{1}{2}

Let us convert our given mixed fractions to improper fractions.

\frac{-7}{3}\times \frac{3}{2}

Upon cancelling out 3 from our given expression we will get,

\frac{-7}{2}

Upon dividing -7 by 2 we will get,

\frac{-7}{2}=-3.5

Therefore, our expression simplifies to -3.5.

Hey!

Hope this helps...

<em>Question 7:</em>  Is the Graph a 1-to-1?

The answer is: No

<em>Reason: </em>If you look at the graph, you see that when the x value is -1 the y value is -2, when x is 0, y is 0.  When x is 1, y is 2, when x is 3, y is 4, and so on and so on...


<em>Question 9:</em> What is f(2)?

The answer is: When f (or x) is 2, y is 3... so f(2) = 3

<em>Reason:</em> (Look at reason for Question 7)


I hope this helped, if it did, please do not forget to give a "Thanks" and a 5 star rating...

And as always, thanks for using Brainly...

±1/2. The equation 4x^{2} =1 has two possible solutions +1/2 and -1/2.

The problem is a quadratic equations and it can be solved using the equation x=-b±\frac{\sqrt{b^{2} -4ac} }{2a}.

Ordering the quadratic equation given in the problem, we obtain 4x^{2} -1=0 where a = 4, b = 0, and c = -1

Substituting the values

x=±\frac{\sqrt{-4(4)(-1)} }{2(4)}=±\frac{\sqrt{16}}{8} =±\frac{4}{8} \\x=±\frac{1}{2}
