Answer:

C

Step-by-step explanation:

f(x)=0 at points of intersection of the graph of the function with x-axis.

From the diagram you can see that the graph of the function intersects x-axis at three points:

  • somewhere between -3 and -2;
  • somewhere between -1 and 0;
  • at x=1.

Since x=1 is the value of x from the domain, then correct choice is option C.

Answer:

When x equals 1. To solve this, just find the x-intercepts, or where the function intersects the x-axis.

Hope this helps!

If the simple interest on $5,000 for 4 years is $1,600, then what is the interest rate?
matrenka [14]

Answer:

0.08, or 8%

Step-by-step explanation:

The appropriate formula is i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.

We want to calculate r when i, p and t are known.

                                                           i

Solving i = p*r*t for r, we get r = ------------

                                                       p*t

The interest rate in this case is

        $1600

r = ---------------- = 0.08, or 8%

      $5000*4

I need help i dont understand this
Ad libitum [116K]

The answer is B)x+y=y+x.

This is just changing the order of the numbers to get the same equation....\

So for example if I have 2+7 and I use the property of addition It would give me 2+7=7+2.

Pls mark brainliest if this helped!

PLEASE HELP PLEASE PLEASE
NNADVOKAT [17]

Answer: The value of x =2 units.

Explanation:

Since we have given that

AD= CD

BE= EA

So, we get that D and E are the mid-points of AC and AB respectively.

So, by Mid- point theorem , which states that the line joining the two midpoints is parallel to third side and it is half in length of third side i.e.

DE=\frac{1}{2}BC

So, we put the value of DE  and BC ,

5x-3=\frac{1}{2}\times (x+12)\\\\2(5x-3)=x+12\\\\10x-6=x+12\\\\10x-x=12+6\\\\9x=18\\\\x=\frac{18}{9}=2

Hence, the value of x =2 units.
