1. 2X + 1 = Y 2Y = 6 Show your work

slamgirl [31]

Answer:

x = 1

y = 3

Step-by-step explanation:

2x + 1 = y ------- eqn (1)

2y = 6--------eqn (2)

from eqn(2)

2y = 6

y = 3

when you divide 6 by 2y

substitute y = 3 into eqn (1)

2x + 1 = y

2x + 1 = 3

2x = 3-1

2x = 2

therefore

x = 1

Determine whether the graphs of the given equations are parallel, perpendicular, or neither. (#2)

masha68 [24]

Look at the slope. if the slopes are the same, the two lines are parallel. if the slopes are negative reciprocals, the lines are perpendicular. otherwise, neither, the two lines will intersect.
6y=x+9
y=(1/6)x+(9/6)
the slope is 1/6, while the second line has a slope of 7, so the two lines have different slopes, so choice D is correct.

189 is 45% of what number? 198 is 55% of what number?

daser333 [38]

189 is 45% of 420 and 198 is 55% of 360

189 = .45x
/.45 /.45
420 = x

198 = .55x
/.55 /.55
360 = x

What are the solutions of the equation x4 95x2 Ă˘â‚¬"" 500 = 0? Use factoring to solve.

liq [111]

All the values of the x for the given function are $\sqrt{5},-\sqrt{5}, 10i$ and $-10i$ .

Given-

Given function is,

$x^{4}+95x^2-500=0$

Rewrite the equation,

$(x^2)^2+95x^2-500=0$

Let u in place of $x^2$ and rewrite the equation in the form of u,

$u^2+95u-500=0$

Break the 95 in factors and rewrite the equation,

$u^2+100u-5u-500=0$

$u(u+100)-5(u+100)=0$

$(u+100)(u-5)=0$

Replace the value of u with $x^2$ ,

$(x^2+100)(x^2-5)=0$

It is known that If any individual factor on the left side of the equation is equal to zero then the entire expression will be equal to zero. therefore we get,

$x^2-5=0$
