Answer:

X=-5

Step-by-step explanation:

100 + 84 - 62x =494

184 - 62x =494

494-184 = -62x

310 =-62x

310/-62 =x

X= -5

Write an equation for the line, given the that m=0 and the y-intercept is (0,-2)
Vika [28.1K]

If you were thinking about slope (explicit) form of the equation

y=m*x+n where m is slope ( angular coefficient) and n intersection on the y axis then equation is y= -2 and it is parallel with x axis.

Good luck!!!

Patel is solving 8x2 + 16x + 3 = 0. Which steps could he use to solve the quadratic equation? Select three options.
MakcuM [25]

Answer:

<em>8(x2 + 2x) = –3 </em>

<em>8(x2 + 2x + 1) = –3 + 8 </em>

<em>x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot</em>

Step-by-step explanation:

<u>Solving Quadratic Equations </u>

Sometimes it's preferred to solve quadratic equations without the use of the known quadratic formula solver. One of the most-used methods consists of completing squares and solving for x.

We have the equation

\displaystyle 8x^2+16x+3=0

We separate variables from constants

\displaystyle 8x^2+16x=-3

Taking the common factor  8

\displaystyle 8(x^2+2x)=-3

Completing squares in the brackets and balancing the equation in the right side

\displaystyle 8(x^2+2x+1)=-3+8

Factoring the perfect square

\displaystyle 8(x+1)^2=5

Isolating x

\displaystyle (x+1)^2=\frac{5}{8}

\displaystyle (x+1)=\pm \sqrt{\frac{5}{8}}

\displaystyle x=-1\pm \sqrt{\frac{5}{8}}

We can clearly see the steps used to solve the quadratic equation are (in order and written like in the question)

8(x2 + 2x) = –3

8(x2 + 2x + 1) = –3 + 8

x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot

What is the equation of line l?
inessss [21]
Y=-3/2L -2. At the Y axis, line L is at -2, so we add that as B or the Y intercept. We can see that the graph goes 2 over to the right and down three, which makes the slope negative and 3/2 (rise/run)
