Y = 4x+2<br>y = -2x - 3

Dima020 [189]

Solve for x and y

y = 4x+2

y = -2x - 3

<h3><u>Answer:</u></h3>

$x = \frac{-5}{6}$ and $y = \frac{-4}{3}$

<h3><u>Solution:</u></h3>

Given equations are:

y = 4x+2 --------- eqn 1

y = -2x - 3 ---------- eqn 2

We have to solve both equations and find values of "x" and "y"

Substitute eqn 1 in eqn 2

4x + 2 = -2x - 3

Combine like terms we get,

4x + 2x = -3 - 2

On solving,

6x = -5

$x = \frac{-5}{6}$

Substitute "x" value in eqn 1

$y = 4(\frac{-5}{6}) + 2\\\\y = \frac{-20}{6} + 2\\\\y = \frac{-20 + 12}{6}\\\\y = \frac{-8}{6} = \frac{-4}{3}$

Thus $x = \frac{-5}{6}$ and $y = \frac{-4}{3}$

Find the value of c that makes x^2–6x + c a perfect square trinomial and write as a binomial squared.

denpristay [2]

Answer: 9

Step-by-step explanation:

Given

The function is $x^2-6x+c$

To make it a perfect square, compare it with $(a-b)^2=a^2+b^2-2ab$

Here,

$x=a,\\-6x=-2ab\\\\\therefore b=3$

So, c must be square of b i.e. 9

$x^2-6x+c\Rightarrow x^2-6x+9\\\Rightarrow (x-3)^2$

Therefore, value of c is 9.
