Consider 8x2 - 48x = -104. Write the equation so that x2 – 6x + (blank) = –13 + (blank)

Answers

Write the equation so that:

-6 and -13

Complete the square:

9 and 9

Hope this helps for Edg.

Answer:

That (blank) is 9.

Step-by-step explanation:

Please write 8x^2 - 48x = -104, with " ^ " indicating exponentiation. Thanks.

This sounds like a perfect example of "completing the square."

First, factor 8x^2 - 48x = -104: 8(x^2 - 6x = -13).

If we focus SOLELY on x^2 - 6x = -13, it's just a little easier to "complete the square." Take half of the coefficient of x (which here is -6), and square that result (which here is (-3)^2, or 9. Now add 9 both sides of x^2 - 6x = -13:

x^2 - 6x + 9 = -13 + 9. Note: The "blank" in the problem statement is 9.

We could go ahead and solve this, tho' we weren't asked to do so. Rewrite x^2 - 6x + 9 as (x - 3)^2:

x^2 - 6x = -13 then becomes (x - 3)^2 = 4. To solve for x, take the sqrt of both sides of this latest result, obtaining x - 3 = plus or minus 2. Add 3 to both sides to isolate x: x = 3 plus or minus 2.

Thus, x = 5 or x = 1.

How do you multiply a decimal by a fraction

Answers

In order to multiply a fraction and a decimal, you have to either change the fraction to a decimal or change the decimal to a fraction then multiply ... for example

1/2 × .8 =

we can change 1/2 to a decimal by doing the division that is described by the fraction... the fraction bar literally means "divided by", so 1/2 means 1 ÷ 2 = .5

Now you can multiply
.8 × .5 = .40 or .4

The other choice would be to convert .8 into a fraction. Look at the place value... the 8 is in the 10ths place so the value is 8 tenths or 8/10. Now multiply
8/10 × 1/2 = 8/20 = 4/5

Solve the equation -4(1.75+x)=18. Show your work.

Answers

The required solution is $x=(-25)/(7)$

Given equation is,

$-4(1.75+x)=18$

Simple linear equation:

Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1.

Now, solving the given equation,

$-4(1.75+x)=18\n-7-4x=18\n-4x=18+7\n-4x=25\nx=(-25)/(7)$
