Can someone solve for x

Helen [10]

bearing in mind that, whenever we have an absolute value expression, is in effect a piece-wise function with a positive and a negative version of the expression, so

$\bf |x^2-4x-5|=7\implies \begin{cases} +(x^2-4x-5)=7\\\\ -(x^2-4x-5)=7 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ +(x^2-4x-5)=7\implies x^2-4x-5=7\implies x^2-4x-12=0 \\\\\\ (x-6)(x+2)=0\implies x= \begin{cases} 6\\ -2 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ -(x^2-4x-5)=7\implies x^2-4x-5=-7\implies x^2-4x+2=0 \\\\\\ (x-2)(x-2)=0\implies x = 2$

Simplify without the absolute value<br> |x+3| ; if x=2

Alja [10]

ANSWER

5

EXPLANATION

We want to simplify:

$|x + 3|$

when x=2.

We substitute x=2 into the absolute value expression to obtain:

$|2 + 3| = |5|$

The about value of 5 means what is the distance of 5 from zero on the real number line.

$|2 + 3| = |5| = 5$

Has an x-intercept of (4,0) and a y- intercept of (0,-2)

Mazyrski [523]

Just to be different we'll start with intercept intercept form which says the line through x intercept (a,0) and y intercept (0,b) is

$\dfrac x a + \dfrac y b = 1$

Through (4,0) and (0,-2) that's

$\dfrac{x}{4} + \dfrac{y}{-2} = 1$

Multiply through by the common denominator of 4 for standard form:

x - 2y = 4

For slope intercept form we solve for y

-2 y = -x + 4

y = (1/2) x - 2

We see our slope is (1/2) and we go through (4,0) so point slope form is

y - 0 = (1/2)(x - 4)

y = (1/2)(x-4)
