Find a possible value of b. 5x2 - bx - 8​

Mathematics
1 answer:
pychu [463]2 years ago
3 0

Answer:

Step-by-step explanation:

Without more input from you, it's hard to find an exact value for b.  However, b may take on a large range of values.  b = 10 and b = -3 (chosen arbitrarily) are acceptable choices.

Take a look at the quadratic formula.  The discriminant is b^2 - 4ac.  There is nothing about this equation that restricts or forbids the use of any value of b.

A board that measures 3/4 feet long is cut into 6 equal pieces. What is the length of each piece?
shusha [124]

Answer:

See below:

Step-by-step explanation:

So we know that there is a \frac{3}{4} feet long board and that it is split into 6 pieces.

With that information, we can split it by doing the following:

1. \frac{3}{4} *\frac{1}{6}

We can do this because we have a board that is 0.75 feet long and we multiply it by one sixth because we want to divide a fraction and to do that we have to flip the fraction.

After doing that, we get our answer of \frac{3}{24}=\frac{1}{8}

This means that each piece is \frac{1}{8} feet long.

Cheers!

Wegnerkolmp or someone please help me with this question about slope....
NNADVOKAT [17]

Answer:

The slope is -3/4

Step-by-step explanation:

We need two points to find the slope

We have one point at (0,5) and we have one point at (4,2)

We can use the slope formula

m = (y2-y2)/(x2-x1)

   = (2-5)/( 4-0)

   = -3/4

The slope is -3/4
