Answer:

We have to add 9 on both sides of the equation.

Step-by-step explanation:

The given equation is x^2 - 6x = 1

Let's identify the value of "b" by comparing the general form of quadratic equation ax^2 + bx + c = 0

Here the value of b = -6

To make it perfect square trinomial, we have to divide b value by 2 and make it square. Then we have to add it on both side of the equation.

(b/2) = (-6/2)^2 = (-3)^2 = -3*-3 = 9

So we need to add 9 on both sides of the equation in order to make it perfect square.

x^2 - 6x + 9 = 1 + 9\\(x -3)^2 = 10

Write equation for the line with a slope "undefined" and has the same x-intercept as x−y−1=0
Mariana [72]

Answer:

Step-by-step explanation:

Lines with undefined slopes are perfectly vertical, of the form "x = ". A line with "the same x-intercept" as the given line that has an undefined slope will be the line that we want. I know that sounds confusing; we'll work through it then I'll explain it better. In order to find the x-intercep of the given line, solving it for y will make it a bit easier to "see". Therefore,

-y = -x + 1 and

y = x - 1. The x-intercept exists when y = 0, so setting y equal to 0 and solving for x:

0 = x - 1 and

1 = x. That's the x-intercept. It's also the line that we want that has an undefined slope, because "x = " lines are lines vertical lines and vertical lines have undefined slopes.

x = 1 is the line you want.

Could some one plz help me with this question
zhuklara [117]

Answer:

A

Step-by-step explanation:

The formula for this type of interest is A=P(1+\frac{r}{n})^{nt}, where A is the total amount, P is the initial investment, x is the interest rate, n is the amount of times that the investment is compounded a year, and t is the amount of years. Plugging in the numbers given, you get:

A=1800(1+\frac{0.025}{2})^{2\cdot 12}=

1800(1.0125)^{24}\approx 2425.23

Now, she invests this into a new account, and you can set up the following equation:

A=2425.23(1+\frac{0.04}{12})^{12\cdot 7}=

2425.23(1.0033333)^{84}\approx 3207.40, or option A.

Hope this helps!
