Nitella [24]

Answer:

$6y - 8$

$2(3y - 4)$

Step-by-step explanation:

The given expresion is 2y-8+4y.

We want to find an expression that is equal to 2y-8+4y.

We need to group like terms to obtain:

$2y + 4y - 8$

We can now combine the like terms to get:

$2y + 4y - 8$

$6y - 8$

We can factor 2 to obtain:

$2(3y - 4)$

Given that points A, B, and C are the midpoints of their respective sides, which of the following is true about the figure? ANSW

Tems11 [23]

Answer:

The correct option is;

$\overline{YZ}\left | \right | \overline{AC}$

Step-by-step explanation:

The dimensions given are;

YX = 2 × AX (A = midpoint of YX)

ZX = 2 × CX (C = midpoint of ZX)

∠X and ∠X are congruent (Reflexive property)

Therefore, triangle XAC is similar to triangle XYZ (SAS similarity theorem)

Since ∠XYZ = ∠XAC segments YZ and AC are parallel from having equal angle on the same side of the transversal YX

Therefore the correct option should be;

$\overline{YZ}\left | \right | \overline{AC}$

PLEASE ANSWER I WILL RANK AND THANK

X + 4y = 9 Convert to slope / intercept form:-

y = (-1/4)x + 9/4

so the line perpendicular to this will have a slope -1 /(-1/4) = 4

so our equation will be y - y1 = 4(x - x1) where x1y1 is a point on the line.
x1 = 8 and y1 = -3:-
y - -3 = 4(x - 8)

y = 4x - 35
-4x + y = -35 is the answer
