2{ 5[12+5 (500 - 100)+399]}

Answers

This is solved by breaking the equasion down.

2 { 5 [12 + 5 (500 - 100) + 399 ]}

2 { 5 [12 + 5 (400) + 399]}

2 { 5 [12 + 2000 + 399]}

2 { 5 [2411]}

2 {12055}

24110

Is this the answer you were looking for?

2(5(12+5(500−100)+399))

=2(5(12+(5)(400)+399))

=2(5(12+2000+399))

=2(5(2012+399))

=2(5)(2411)

=(2)(12055)

Which of the following statements must be true whenever n, a, b, and c are positive integers such that n < a, c > a, and b > c ?A. a < n
B. b – n > a – n
C. b < n
D. n + b = a + c
E. 2n > a + b

Answers

b is true,
since b is larger than a. we see this from the 2 last statements.
n is subtracted form both of them, so b is still larger, and b-n is larger than a-n

Final answer:

The statement that must be true is n + b = a + c.

Explanation:

The correct statement among the given options is D. n + b = a + c.

Given that n < a, c > a, and b > c, we can see that the sum of n and b must be equal to the sum of a and c. This is because n + b represents the sum of the smaller numbers, while a + c represents the sum of the larger numbers, so if n + b is not equal to a + c, then the given conditions would not hold true.

For example, let's say n = 2, a = 4, c = 6, and b = 8. In this case, n + b = 2 + 8 = 10, and a + c = 4 + 6 = 10. So, the statement n + b = a + c is true.

What is the standard form of the equation of the circle in the graph

Answers

When an equation of circle is expressed in the form:

(x-h)^2 + (y-k)^2 = r^2

(h, k) is the center and r is the radius.

The center = the coordinate you have plotted on the graph.

Radius = how many units long the circle extends to.

SO, let's plug this in.

Coordinate plotted = (0, -4)

0 = h

-4 = k

(x - {0})^2 + (y - {-4})^2 = 2^2

(x - 0)^2 + (y + 4)^2 = 4

(whenever we have two negative signs next to each other, it turns the digit to the right of the final negative sign positive.)

Now we are left with this final equation as a solution:

x^2 + (y + 4)^2 = 4.

I hope this helped~!

The standard form of a circle:

$(x-h)^2+(y-k)^2=r^2$

$(h;\ k)$ - the coordinates of a center of a circle

$r$ - the radius

We have:

the center: $(0;\ -4)$

the radius: $r=2$

substitute

$(x-0)^2+(y-(-4))^2=2^2\n\nx^2+(y+4)^2=4$
