Answer:

x = 0, y = 2

Step-by-step explanation:

Substitute the first equation into the second equation so 3x + 3(x+2) = 6. Simplify this to get x = 0. Plug x = 0 back into the first equation to get y = 2.

Answer:

x = 0, y = 2

Step-by-step explanation:

y = x + 2

3x + 3y = 6

3x + 3(x + 2) =6

3x + 3x +6 = 6

6x = 0

x = 0

y = x + 2 = 0 + 2 = 2

The value of variable x in the equation is x = c - k / 3

3x+ k = c

let's find x or make it the subject of the formula,

3x + k = c

subtract k from both sides of the equation

3x + k - k = c - k

3x = c - k

divide both sides by 3

3x / 3 = c - k / 3

Therefore,

x = c - k / 3

Answer:

x = 12

Step-by-step explanation:

x = length of side of square A

'x-3' represents length of side of square B

Perimeter of square A = 4x

Perimeter of square A = 4x - 12

we can set up the following proportion based on ratio of 4:3

4x / 4 = 4x - 12 / 3

cross-multiply:

4(3x) = 4(4x-12)

12x = 16x - 48

-4x = -48

x = 12

Answer:

Inside the circle, a distance of [tex]\sqrt{34}[/tex] from the center of the circle.

Step-by-step explanation:

Center of circle is at (0,0)

One point of the circle is at (0,[tex]\sqrt{38}[/tex])

Since the only known point is in the y-axis, the radius of the circle must be [tex]\sqrt{38}[/tex].

[tex]\sqrt{38}[/tex] = 6.164

So the point (-5,-3) is still inside the circle as the distance from point (-5,-3) to the center of the circle is [tex]\sqrt{(5)^2+(-3)^2}[/tex] or [tex]\sqrt{34}[/tex] which is less than the radius of the circle.

Point N(-5, -3) lies inside the circle.

We have,

To determine the location of point N(-5, -3) in relation to the given circle centered at C(0, 0), we can calculate the distance between point C and point N.

- If the distance is equal to the radius of the circle, then N lies on the circle.

- If the distance is greater than the radius, N lies outside the circle.

- If it is smaller, N lies inside the circle.

Let's calculate the distance between C(0, 0) and N(-5, -3):

Distance = √[(x2 - x1)² + (y2 - y1)²]

= √[(-5 - 0)² + (-3 - 0)²]

= √[25 + 9]

= √34

Since the distance (√34) is less than the radius of the circle, which is √38 (distance between C and M), we can conclude that the point N(-5, -3) lies inside the circle centered at C(0, 0).

Thus,

Point N(-5, -3) lies inside the circle.

Halfway Between 0 and 121

Halfway Between

When you ask "What number is halfway between 0 and 121?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=0 and Y=121.

Halfway Between Line

To find the number halfway between 0 and 121, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 121 into our formula, we get:

(0 + 121)/2 = 60.5

Thus, the number halfway between 0 and 121 is 60.5

Answer:

solution given;

half way between 0 and 121=?

let a=0

and

b=121

we have

halfway =[a+b]/2=[0+121]/2=60.5

half way between 0 and 121 is 60.5

Angle D and angle B are congruent because they are corresponding angles. Angle E and C are also congruent because they are corresponding angles.

to be honest i just looked it up it thats what i do with my work and i always get it right so...

Answer:

9x ^2 − 25

Explanation:

( a + b ) ( a − b ) = a ^2 − ^b 2

substitute  a  with  3 x  and  b  with 5:

( 3 x + 5 ) ( 3 x − 5 ) = ( 3 x ) 2 −5^ 2 = 9 x ^2 − 25

( 3 x + 5 )( 3 x − 5 ) =  9 x ^2 − 25

Answer:

9x² - 25

Step-by-step explanation:

(a - b)(a + b)= a² - b²

a = 3x   ; b = 5

(3x - 5 )(3x + 5)= (3x)² - 5²

                        = 3²x² - 25

                        = 9x² - 25

The sequence is arithmetic

Step-by-step explanation:

Here we want to determine the sequence is arithmetic

If the sequence was arithmetic, the difference between the terms would be constant

We have this as;

10-(-12) = 22

32-10 = 22

54-32 = 22

As we can see, the difference is constant and so we have it that the sequence is arithmetic
