Value of m{8+[b(m-1)+3]} when m = -2 and b = 2/3

Mathematics
1 answer:
Mrrafil [7]2 years ago

Answer:

-18

Step-by-step explanation:

m = -2                 Start with the expression that is within the most number of brackets.

m - 1 = -2 - 1 = -3

Multiply that result by 2/3

-3 * 2/3 = - 2

To that result add 3 which will get you through the square brackets.

- 2 + 3

+ 1

Just outside the square bracket is 8 Eight should be added to 1

8 + 1 = 9

Now you multiply that result by - 2

-2 * 9

= - 18

The answer is 6

Write a quadratic relation in the form y = ax2 + bx + c with roots 4 and - 3 and
pochemuha

Answer:

y =  2*x^2 - 2*x - 24

Step-by-step explanation:

If we have a quadratic function with roots a and b, we can write the equation for that function as:

y = f(x) = A*(x - a)*(x - b)

Where A is the leading coefficient.

In this case, we know that the roots are: 4 and -3

Then the function will be something like:

f(x) = A*(x - 4)*(x - (-3) )

f(x) = A*(x - 4)*(x + 3)

Now we need to determine the value of A.

We also know that the graph of the function passes through the point (3, -12)

This means that:

f(3) = -12

Then:

-12 = A*(3 - 4)*(3 + 3)

-12 = A*(-1)*(6)

-12 = A*(-6)

-12/-6 = A

2 = A

Then the equation is:

y = f(x) = 2*(x - 4)*(x + 3)

Now we need to write this in standard form, so we just need to expand the equation:

y = f(x) = 2*(x^2 + x*3 - x*4 - 4*3)

y = f(x) = 2*(x^2 - x - 12)

y = f(x) = 2*x^2 - 2*x - 24

Then the relation is:

y =  2*x^2 - 2*x - 24
