The sum of a number and its additive inverse is equal to _____.

1 answer:

7 0

The sum of a number and its additive inverse is equal to zero. The correct option among all the options that are given in the question is the second option or option "b". If we assume "x" to be a real number, then its additive inverse is "-x". On adding these two, we can see that the result comes to zero.

F(-1) f(x) = -3x2 + 2x - 7

egoroff_w [7]

Answer:

$f(-1) = -12$

Step-by-step explanation:

<u>Step 1: Set x to -1 and solve</u>

<u /> $f(x) = -3x^2+2x-7$

$f(-1) = -3(-1)^2+2(-1) - 7$

$f(-1) = -3(1) - 2 - 7$

$f(-1) = -3 - 2 - 7$

$f(-1) = -12$

Answer: $f(-1) = -12$

Write the quadratic equation whose roots are 5 and -3, and whose leading coefficient is 1

kogti [31]

1. A quadratic equation has the following form: ax²+bx+c.

2. The leading coefficient is the number that is attached to the variable with the highest exponent. Then, the "a" is the leading coefficient of the quadratic equation.

3. The problem says that the leading coefficient is 1 (a=1) and the roots of the quadratic equation are 5 and -3. Then, you have:

(x-5)(x+3)=0

4. When you apply the distributive property, you obtain:

x²+3x-5x-15=0
x²-2x-15=0

5. Therefore, the answer is:

x²-2x-15=0
