-2x + y = 6 <br> -2x + y = -1<br> Plz help with this problem<br> Elimination

vladimir1956 [14]

The answer is no solution

Step-by-step explanation:

The equation is $-2x+y=6$ and $-2x+y=-1$

Subtracting these two equations, we get,

$-2x+y=6\\-2x+y=-1\\-------\\0=7$

Thus, $0=7$ is not possible.

Hence, the system of equations have no solutions.

PLEASE HELP I WILL GIVE 100 POINTS!!!!!!!!Given rectangle ABCD ~ HGFE , what is the length of HG ?

never [62]

Since rectangle ABCD is similar to HGFE, the ratios of the lengths of their corresponding sides are equal. We can infer form our picture that AD is corresponding to EH and DC is corresponding to HG, so lets find the ratios of those corresponding sides and establish a proportion to find the length of HG:
$\frac{AD}{EH} = \frac{DC}{HG}$
We know that $AD=45$ , $EH=27$ , and $DC=15$ , so lets replace those values in our proportion:
$\frac{45}{27} = \frac{15}{HG}$
$HG= \frac{27*15}{45}$
$HG= \frac{405}{45}$
$HG=9$

We can conclude that the length of the segment HG is 9.
