Solve this problem: –282 – (+1,017) =

Answers

Answer 1

Answer: This question more or less tries to trick you with the positive number in parentheses, as you would carry out subtraction as normal. However, since the number you are subtracting from is also negative, it would be easier to think about it as adding two positives, and setting aside the negative symbol for the answer.

-282 - 1017 = -(282 + 1017) = -(1299) = -1299

which is your final answer.
-282 - (+1017) = -1299.
Hope that helped! =)

Step-by-step explanation:

hope this helps

If the given is -1= 3 + 4x then the answer is x= -1

-1= 3 + 4x

-1-3=4x

-4=4x

To find the x divide both sides by 4.

-4/4=4x/-4

x= -1

To find the vertex form of parabola $y=a(x-x_0)^2+y_0$ given in almost standard form $y=ax^2+bx+c,$ were written following steps:

1. Write the function in standard form:

$y=3x^2+18x.$

2. Factor a out of the first two terms:

$y=3(x^2+6x).$

3. Form a perfect square trinomial:

$y=3(x^2+6x+9-9)=3(x^2+6x+9)-3\cdot 9.$

4. Write the trinomial as a binomial squared:

$y=3(x+3)^2-27.$

The vertex is (-3,-27).

Answer: missing value is 3

The function in vertex form is y = 3( x+3)² -9

What is a Function ?

A function is a mathematical statement formed for relating a dependent and in independent variable.

It is given that

f(x) = 18x +3x²

To write it into vertex form

The standard vertex form is given by

y =a(x- h)² +k

y = 18x +3x²

y = 3(x² +6x)

y = 3 (x² + 2.3 x + 9) -9

y = 3( x+3)² -9

Therefore in vertex form the function is y = 3( x+3)² -9
