The value of x is -3! ^^

$\stackrel\star{\rightsquigarrow\circ\boldsymbol{\underbrace{Explanation}}}\circ\leftharpoonup$

$\bullet$ First multiply 5 times 1 and -x

$\twoheadrightarrow\sf 5(1-x)=20$

$\twoheadrightarrow\sf 5-5x=20$

$\bullet$ Now subtract 5 from both sides

$\twoheadrightarrow\sf -5x=15$

$\bullet$ Now divide both sides by -5

$\twoheadrightarrow\sf x=-3$

Hope that this helped! Best wishes.

Ryker is given the graph of the function y= 1/2x^2 - 4 . He wants to find the zeros of the function but is unable to read them e

REY [17]

$y = \frac{1}{2x^{2} - 4}$
$0 = \frac{1}{2x^{2} - 4}$
$0(2x^{2} - 4) = (2x - 4)(\frac{1}{2x^{2} - 4})$
$0(2x^{2}) - 0(4) = 1$
$0 - 0 = 1$
$0\neq1$

What is the slope of 2x+3y=15

Fynjy0 [20]

Note that the slope-intercept form is: y = mx + b

First, set the equation as such

2x (-2x) + 3y = (- 2x) + 15

3y = -2x + 15

Isolate the y. Divide 3 from both sides

(3y)/3 = (-2x + 15)/3

y = (-2/3)x + 5

-2/3 is your slope

hope this helps
