Answer:

The x-coordinate of the solution to this system of equations is 2

Step-by-step explanation:

we have

3x-y=2 ------> equation A

x+y=6 ------> equation B

Adds equation A and equation B

3x-y=2\\x+y=6\\--------\\ 3x+x=2+6\\4x=8\\x=2

<span>3x − y = 2

y = 3x - 2

x + y = 6

x + 3x - 2 = 6

4x - 2 = 6

4x = 6 + 2

4x = 8

x = </span>\frac{8}{4}

x = 2

Hence, the x co-ordinate is 2.

Someone please help me please
sertanlavr [38]

Answer:

D.   (x - 2)(x + 2)

Step-by-step explanation:

Look at the graph, when y = 0, x = - 2 and x = 2, vertex = -4

OK so x = -2 means x + 2 = 0

and x = 2, means x - 2 = 0

So

answer :D.  (x - 2)(x + 2)

Write an expression equivalent to `m+m+m+m` that is a product of a coefficient and a variable. Please include an explanation!
Marina CMI [18]

Answer:

4m

Step-by-step explanation:

it would be 4m because there are four different copies and the variable being used originally is 'm'. therefore, we can move it around and since addition is basically the longer version of multiplication, we would correct this to 4m.

good luck :)

i hope this helps

have a nice day !!

what is the circumference of a circle that has a radius of 8 units use 3.14 (pie) and round to the nearest hundredth
SashulF [63]

Remember that the formula for the circumference, C, of a circle is:

C = d \pi


In this case, we are not given the diameter. However, remember that the diameter is equivalent to two times the radius of a circle. Thus,

d = 2 \cdot 8 = 16,

and we can say the circumference of our circle is:

C = 16 \cdot 3.14 = 50.24 \,\textrm{units}


The circumference of our circle is 50.24 units.


<em>Also, a little side note not relating to the question:</em>

<em>Remember that \pi is spelled as "pi" not "pie." Pie is a dessert, while pi is a mathematical constant.</em>
