Answer: A

We could solve it but it's easier to just check the given solutions.

A. (7,1)

2y + 5 = 2(1)+5 = 7 = x, good

x/3-y = 7/3 - 1 = 4/3, good

B. (-3,8)

2y + 5 = 2(8)+5 = 21 not x=-3, doesn't check

C. Can't be true because we found a solution

D.  Infinitely many solutions not true because the lines have different slopes

.−3(4x + 3) + 4(6x + 1) = 43<br> What is the solution?
maks197457 [2]

Answer:

  x = 4

Step-by-step explanation:

After you simplify the left side by eliminating parentheses and collecting terms, you have a 2-step linear equation.

  -3(4x +3) +4(6x +1) = 43 . . . . . . given

  -12x -9 +24x +4 = 43 . . . . . eliminate parentheses

  12x-5 = 43 . . . . . . . . . . . collect terms (now a 2-step equation)

  12x = 48 . . . . . . . . . . step 1, add the opposite of the unwanted constant

  x = 4 . . . . . . . . . . . step 2, divide by the coefficient of x

The solution is x = 4.

__

<em>Check</em>

  -3(4·4 +3) +4(6·4 +1) = 43 . . . . substitute for x

  -3(16 +3) +4(24 +1) = 43

  -3(19) +4(25) = 43

  -57 +100 = 43 . . . . . true

Decide whether there is enough information to prove that △WXZ≅△YZX using the SAS Congruence Theorem.
Ratling [72]

Answer:

D

Step-by-step explanation:

ΔWXZ and ΔYZX

WZ ≅XY    {Given}

ZX ≅ ZX      {Reflexive property}

∠W ≅ ∠Y

But for SAS congruent the congruent angles should between congruent sides( WX & WZ should be congruent to ZY & XY respectively).

So it cannot be proved using SAS congruent
