factor completely 4n^2-28n+49

Answer:

Step-by-step explanation:

2x - 5y = 6

5y = 2x - 6

y = 2/5x - 6/5

y-intercept is -6/5

x-intercept is when you say that y = 0

and so 6/5 = 2/5x

x = 6/2 = 3

Answer:

The distance between the two stars in miles is 5.292 * 10^10 miles

Step-by-step explanation:

Here, we want to make a conversion from light year to miles

To make this conversion, we simply are going to multiply the light year by the miles

Mathematically, we have this as;

9 * 10^-3 * 5.88 * 10^12

= 52.92 * 10^9

= 5.292 * 10^10 miles

8 cups would be 4 pints for your problem

Answer:

C. 27

Step-by-step explanation:

((4x + 5) + 10)*10 = (21 + 9)*9 (two secants intersecting)

(4x + 5 + 10)*10 = (30)*9

(4x + 15)*10 = 270

40x + 150 = 270

40x = 270 - 150 (subtraction property of equality)

40x = 120

Divide both sides by 40

40x/40 = 120/40

x = 3

✔️QS = (4x + 5) + 10

Plug in the value of x

QS = 4(3) + 5 + 10

QS = 12 + 5 + 10

QS = 27

Answer:

Subtract 4 from both sides of the equation

6+4=3+13

6+4−4=3+13−4

Simplify

Subtract the numbers

6=3+9

Subtract 3 from both sides of the equation

6x=3+9

6−3=3+9−3

Simplify

Combine like terms

3=9

Divide both sides of the equation by the same term

3=9

3/3=9/3

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

=3

Solution

x=6 , y = 4

Step-by-step explanation:

( x-2,6)=(4,Y+2)

this means; (x-2) &( 4) stands for" x "axis.

and( 6 )& (y+2) stands for y axis.

So, we can say( x-2)=X1 & (4)=X2 , (6)=Y1 & (y+2)=Y2

then; to Solve The Equation we use The Formula: X1=X2 for "X" And Y1=Y2 for "Y".

Solution: for "X" ; X1=X2

x-2= 4

x=4+2

x=6

For "Y" ; Y1=Y2

6 = y+2

y=6-2

y=4

finally check ; ( (x-2),6) = (4,(y+2) )

(6-2),6 = (4,(4+2) )

( (4),6) = (4,(6) )

(4,6) = (4,6)

so, X1 =X2 ; 4 = 4

Y1 = Y2 ; 6 = 6

Answer:

3Ax-6x = 15

3x(A-2)=15

If A were 2, the left side of the equation would be 0 and it wouldn't equal 15 no matter what the value of x is. So A is 2

Answer:

x=1,y=3

correct answer is (1,3)

Step-by-step explanation:

We can quickly eliminate y by subtracting one equation from the other

(-2x+y=1)-(-4x+y=-1)

2x=2

x=1

plug x=1 into equation 1

-2(1)+y=1

y=1+2=3

Answer: 32

Step-by-step explanation:

The expression that is equivalent to 2^2 divided by 2/2^4 would be calculated as:

= 2^2 ÷ 2/2^4

= 4 ÷ 2/16

= 4 ÷ 1/8

= 4 × 8

= 32

The expression would be equal to 32 based on the above calculation

Answer:

3/2x=6 X=4

Step-by-step explanation:

Answer:

a. x = 12

b. x = 4

Step-by-step explanation:

a.  [tex]\frac{2x}{3}=8[/tex]

Multiply both sides by 3;

[tex]\frac{2x}{3} *3=8*3\\\\2x=24[/tex]

Divide both sides by 2;

x = 12

b.  [tex]\frac{3x}{2}=6[/tex]

Multiply both sides by 2;

[tex]\frac{3x}{2}*2=6*2\\\\3x=12[/tex]

Divide both sides by 3;

x = 4

Responder:

1) x² + y²-8x + 10y + 16 = 0

2) x² + y² + x + 18y + 33 = 0

Explicación paso a paso:

A partir de la pregunta, debemos expresar la ecuación en la forma estándar de un círculo expresado como;

x² + y² + 2gx + 2fy + c = 0 donde;

(-g, -f) es el centro.

1) Para la ecuación (x-4) ² + (y + 5) ² = 25

Expande el paréntesis;

(x-4) ² + (y + 5) ² = 25

x²-8x + 16 + y² + 10x + 25 = 25

x²-8x + 16 + y² + 10y + 25-25 = 0

Recopile términos similares;

x² + y²-8x + 10y + 16 + 0 = 0

x² + y²-8x + 10y + 16 = 0

Por lo tanto, la ecuación requerida es x² + y²-8x + 10y + 16 = 0

2) Para la expresión (x + 1) ² + (y + 9) ² = 49

x² + x + 1 + y² + 18y + 81 = 49

x² + x + 1 + y² + 18y + 81-49 = 0

Recopile términos similares;

x² + y² + x + 18y + 82-49 = 0

x² + y² + x + 18y + 33 = 0

Por tanto, la ecuación requerida es x² + y² + x + 18y + 33 = 0

Answer:

Step-by-step explanation:

a. It is a decay function as number of population is decreasing over time

b. f(n) = 33500*((100 - 2.5)/100)^n = 33500*(0.975)^n

c. In year 2025, n = (2025 - 1995)/10 = 3

f(3) = 33500*(0.975)^3 = 31100 rounded up

Answer:

X = 5a+5g

Step-by-step explanation:

Adding g on both sides gives:

X/5 = a+g

Now dividing 5 on both sides gives us the value of x which is:

X = 5(a+g)

Hence X=5(a+g) or X=5a+5g( multiplying by 5 gives us 5a and 5g)

Answer:

x= -14

Step-by-step explanation:

-x+3x-x=-8-6

x= -14

-x+8+3x=x-6

the first thing we need to do is move the x's to the left and the numbers to the right

when moving a number from one side to another it's sign is changed

-x+3x-x=-6-8

x=-14

Step-by-step explanation:

Answer:

x = 2, y = -1

Step-by-step explanation:

To solve this with elimination, we first multiply the first equation by -2.5

Our new equations are:

-5x - 7.5y = -2.5

5x – 4y = 14

After adding these two equations together, the x cancels out and we have:

-11.5y = 11.5

Divide both sides by -11.5

y = -1

Plugging this value into y in one of the equations we have:

2x + 3y = 1

2x + 3(-1) = 1

2x - 3 = 1

Add 3 to both sides

2x = 4

Divide both sides by 2

x = 2

99,000

Step-by-step explanation:

since 3 times 10 to the power of 3 is 1000 and 10 to the power of 5 is 100000 the answer is 99,000

Answer: 97000 more

Step-by-step explanation:

10*10*10*10*10=100000  10⁵

10*10*10=1000*3=3000    10³

So 100000-3000= 97000 more

f(x) and g(x) are not closed under subtraction because when subtracted, the result will be a polynomial, the correct option is B.

According to Closure Property, when something is closed, the output will be same as the input.

The polynomials f(x) and g(x) can be seen in the image.

On subtracting the two polynomials, the output will be a polynomial and so it is closed under subtraction.
