Answer:

$a+(-a)=0$

Step-by-step explanation:

Let $a\in \mathbb R$ , that is a be any real number.

The inverse property of addition says that, the sum of a number $a$ and its additive inverse $-a$ gives the identity element of addition which is zero.

That is :

$a+(-a)=0$

We can rewrite this as $-a+a=0$

From the above options, we have the correct answer to be the first choice

Sales of SUVs (sport utility vehicles) in the United States (in millions) for the years 1990-1999 can be modeled by the quad

Andrei [34K]

If x = 0 is 1990, x = 1 is 1991, then 1998 is represented by x = 8. Substitute this value of x into the quadratic equation to find y:
y = 0.016*(8^2) + 0.124*8 + 0.787 = 1.024 + 0.992 + 0.787 = 2.803
Therefore, there were approximately 2.803 million SUVs sold in 1998.

Can someone explain how u can write a percent in simplest form?

mash [69]

Answer:

The answer is 1 1/4 or a.

Step-by-step explanation:

Basicallly percents are based of 100% so there is a 100% which would be a whole then there is only 25% and if you take 4 quarters and each quarter is 25 cents and there is 4 quarters in a whole that would be 1/4. You add the 1 whole and the 1/4 to get 1 1/4.

Hope this helps, tried to explain it in the best way I can.

Number two please <br> ASAP

The solutions for $-5 +2x^{2} = -6x$ is option 3. $x= \frac{-6 \pm \sqrt{36-4 (2)(-5)}}{4} .$

Step-by-step explanation:

Step 1:

First, we must bring the equation to the form of $ax^{2} +bx +c =0.$

So $-5 +2x^{2} = -6x$ becomes $2x^{2} +6x-5=0.$

The value of a is the coefficient of the $x^{2}$ term, the value of b is the coefficient of x term and c is the coefficient of the constant term.
