Part A: first multiply 2 by x and -3, then combine the like terms, after that add 6 from both sides, then subtract 6x from both side, the answer is -5.
 4x + 2(x-3) = 4x + 2x - 11
          4x +2x -6 = 4x + 2x - 11
           6x -6 = 6x - 11
           6x = 6x -11 +6
         6x = 6x -5
          6x-6x= -5 
         0 = -5 
 part B) add the like terms

Answer:  There is no solution to the equation ad we have used distributive property to solve the equation.

Step-by-step explanation:  The given equation is

4x+2(x-3)=4x+2x-11.

PART A:

The solution of the above equation is as follows:

4x+2(x-3)=4x+2x-11\\\\\Rightarrow 4x+2x-6=6x-11\\\\\Rightarrow 6x-6=6x-11\\\\\Rightarrow -6=-11,

which cannot be TRUE.

So, the equation will not have any solution.

PART B: We have used DISTRIBUTIVE PROPERTY to solve the equation, which states that

for any real numbers a, b and c

(i) a(b + c) = ab + ac,

(ii) (a + b)c = ac + bc.

Thus, there is no solution to the equation ad we have used distributive property to solve the equation.

What is the constant of variation,k, of the direct variation,y=kx,through (5,8)
grigory [225]

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form \frac{y}{x}=k or y=kx

where

k is the constant of variation

in this problem we have

the point (5,8)

so

x=5\\y=8

substitute

\frac{y}{x}=k

\frac{8}{5}=k

therefore

<u>the answer is</u>

k=\frac{8}{5}

A red-light flashes every 28 seconds. A green light flashes every 24
Maslowich

Answer:

168 seconds

I edited the answer.

Step-by-step explanation:

To find the the time taken for both lights to flash at the same time, we need to find the lowest common multiple of 28 and 24.

28 x 6 = 168, 24 x 7 = 168

The LCM of 28 and 24 is 168.

So it takes 168 seconds for both lights to flash at the same time.

Eddi Din [679]

Answer:

-6

Step-by-step explanation:

The equation is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

The y intercept is the value when x = 0

The y value is -6 when the x value is 0

y = -4x+ (-6)

The congruent statement and the reason why the triangles are congruent is (b) ΔUVZ ≅ ΔVYX, SSS

<h3>How to determine the congruent statement and the reason?</h3>

From the question, we have the following parameters that can be used in our computation:

Triangles = UVZ and VYX

There are several theorems that make any two triangles to be congruent

One of these theorems is the SSS congruent theorem

The SSS congruent theorem implies that the corresponding sides of the triangles in question are congruent

From the question, we can see that the following corresponding sides on the triangles UVZ and VYX have the same mark

UV and VY

UZ and VX

VZ and YX

This implies that these sides are congruent sides

Hence, the congruent statement on the congruency of the triangles is (b) ΔUVZ ≅ ΔVYX and the reason is by SSS
