SOMEONE PLEASE HELP ME ASAP PLEASE!!!

Answer:

y = x - 5

Step-by-step explanation:

The equation given to us is;

y = x - 3

y = (1)x + (-3)

y = mx + c

Where m = slope of the line = 1

As parallel line have same slope, slope of second line is also 1

Use general equation to find line

y = mx + c

y = 1x + c

y = x + c

Substitute (3,-2) in the given equation:

-2 = 3 + c

c = -5

Substitute m=1 and c=-5 in general equation to find the equation of line:

y = mx + c

y = x - 5

Which expressions are equivalent to (4⋅a)⋅2 Drag and drop the equivalent expressions into the box. A. 4 x (a x 2) B. 4x2xax2 C 8

aksik [14]

(4*a)*2

lets give a a number: a = 3 so (4*3)*2 = 12*2 = 24

lets try the options:

A) 4 *(3*2) = 4*6 = 24 = the same

B) 4*2*3*2 = 8*3*2 = 24*2 = 48 = different

C) 8*3 = 24 = same

D) 4*2+3*2 = 8 +6 = 14 = different

E) 2*(4*3) = 2*12 = 24 = same

so A, C & E would be the equivalent.

What is the solution of the system?

Kryger [21]

Greetings!

Solve the System, using Elimination:
$\left \{ {{4x+2y=18} \atop {2x+3y=15}} \right.$

Multiply Equation #2 by 2:
$\left \{ {{4x+2y=18} \atop {2(2x+3y)=2(15)}} \right.$

$\left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.$

Eliminate variable x:
$-\frac{ \left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.}{0x-4y=-12}$

$4y=-12$

Divide both sides by 4:
$\frac{4y}{4}= \frac{12}{4}$

$y=3$

Input this value into one of the Equations:
$4x+2y=18$

$4x+2(3)=18$

Simplify:
$4x+6=18$

$(4x+6)+(-6)=(18)+(-6)$

$4x=12$

Divide both sides by 4.
$\frac{4x}{4}= \frac{12}{4}$

$x=3$

The Solution to this System (The Point of Intersection):
$\boxed{(3,3)}$

I hope this helped!

Find the measure of each angle of a regular pentagon.<br> 36°<br> 108°<br> 144°<br> 72°

iragen [17]

Answer:

The Correct Option is Second one 108°.

Hence, the measure of each internal angle of a regular Pentagon is 108°.

Step-by-step explanation:

Given:

A Regular Pentagon.

Accordingly, for a Pentagon, the total of the internal angles is given by,

$\textrm{Total Measure Internal Angles}=(5-2)\times 180\° = 3\times 180\°= 540\°$
