7 0

Answer: -3x + 7

Step-by-step explanation: All you have to do is combine like terms

First, you combine 3x - 6x which, will give you -3x

Second, you combine 12 - 5 which will give you 7

3x - 6x = -3x

12 - 5 = 7

So, combine the answers and you will get -3x + 7

Overline MD cong overline LS additional information is necessary to show that triangle MTD cong triangle LGS by SSS?

aivan3 [116]

Answer:

$TD \cong GS$

Step-by-step explanation:

See comment for complete question

Given:

$TM \cong GL$

$MD \cong LS$

Required

The information that shows $\triangle MTD \cong \triangle LGS$ by SSS

By SSS implies that, the three sides of both triangles are congruent

Already, we have:

$TM \cong GL$

$MD \cong LS$

The third side of $\triangle MTD$ is $TD$

The third side of $\triangle LGS$ is $GS$

So, for both to be congruent by SSS, the third sides must be congruent

i.e.

$TD \cong GS$

ANYONE GOOD AT MATH? PLEASE PLEASE PLEASE SOMEONE HELP ME :(

Mumz [18]

Answer:

The parent function is $f(x)=a(x-h)^{2} +k$

That Parabola's equation is $f(x)=x^{2}$

Step-by-step explanation:

I can't really explain much, but the top equation is a formula for all equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.

How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.

194 in radical form is just √194. I don't believe any square roots go into it. Hope that helps. :)
