$2x + ( - 2x - 6) = 5 \\ - 6 = 5 \\$

Y= -2x-6
2x+y=5 so then y= -2x+5

If you look at those two equations and ask yourself when is
y = a number-6 and in the same time
y = same number +5
The answer is never, so the system of equations has no solutions

Answer:

$[f(x)]^2-g(x) = 5x^2-13x-8$

Step-by-step explanation:

Given

$f(x) = 2x-2\\g(x) = -x^2+5x+12$

To find: $[f(x)]^2-g(x)$

First of all the square of first function f(x) will be found and then second function g(x) will be subtracted from the square of first function

Squaring the first function

$[f(x)]^2 = (2x-2)^2\\Using\ (a-b)^2 = a^2-2ab+b^2\\\[f(x)]^2 = (2x)^2-2(2x)(2)+(2)^2\\= 4x^2-8x+4$

Now subtracting g(x) from [f(x)]^2

$[f(x)]^2-g(x) = (4x^2-8x+4)-(-x^2+5x+12)\\\[f(x)]^2-g(x) = 4x^2-8x+4+x^2-5x-12$

Combining alike terms

$[f(x)]^2-g(x) = 4x^2+x^2-5x-8x+4-12\\\[f(x)]^2-g(x) = 5x^2-13x-8$

Hence,

Subtracting g(x) from the square of f(x) gives us:

$[f(x)]^2-g(x) = 5x^2-13x-8$

you have a credit card that has a balance of 3589.90 and a credit limit of 5000. how much is the balance over the acceptable deb

Fed [463]

The correct answer for this question is this one: 1410.10

You have a credit card that has a balance of 3589.90 and a credit limit of 5000. The balance over the acceptable debt ratio percentage is

= 5000 - 3589.90
= 1410.10
Hope this helps answer your question and have a nice day ahead.

Identity whether the following points are collinear . (2 , 3 ) (4 , 7 ) (8 , 11 )

Natasha_Volkova [10]

Answer:

not collinear points

Step-by-step explanation:

If the points are collinear ( lie on the same line ) then the slopes between adjacent points will be equal.

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$
