ow do you find the radius of a circle using the circumference?

Step-by-step explanation:

(x1,y1) = (-2,5)

(x2,y2) = (5,-2)

(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)

(y - 5)/(-2 - 5) = (x + 2)/(5 + 2)

(y - 5)/-7 = (x + 2)/7

(y - 5)/-1 = (x + 2)/1

y - 5 = -(x + 2)

y - 5 = -x - 2

y = -x -2 + 5

y = -x + 3

Answer:

The answer is A, because this expression translates to the number of students on the 6th floor being greater than (due to the < symbol) the number of students of the 1st and 2nd floor combined (due to the + symbol).

Answer:

BC = 6

Step-by-step explanation:

Look at two corresponding sides that have both lengths given.

They are AB = 4 and XY = 3.

We need BC, and its corresponding side YZ = 4.5.

We can use a proportion.

BC/YZ = AB/XY

a/4.5 = 4/3

3a = 4.5 * 4

a = 1.5 * 4

a = 6

Answer: BC = 6

Answer:

interest earned is $176

Step-by-step explanation:

Interest = Principal x Rate x Time

I = 880 x .04 x 5

I = 176

Answer:

$176

Step-by-step explanation:

Simple interest  = P ( initial money )*r (rate ) *t ( time )

P = $880

r = 4% = 0.04

t = 5 years

Simple interest  = 880 * 0.04 * 5 = $ 176

Interest you earn in 5 years is $176.

Slope, in the form of y = mx + b, is m

[1] 9

    () It is the m

[2] -1/2

    () It is the m

[3] 2

    () add 2x to both sides

[4] 3/4

    () add 4y and subtract 12 from both sides (4y = 3x - 12) and then divide by 4

Me please I have been having a bad day…

Answer:

(0.5, 1 )

Step-by-step explanation:

y = 4x - 1 → (1)

2x + 2y = 3 → (2)

Substitute y = 4x - 1 into (2)

2x + 2(4x - 1) = 3 ← distribute parenthesis and simplify left side

2x + 8x - 2 = 3

10x - 2 = 3 ( add 2 to both sides )

10x = 5 ( divide both sides by 10 )

x = [tex]\frac{5}{10}[/tex] = 0.5

Substitute x = 0.5 into (1)

y = 4(0.5) - 1 = 2 - 1 = 1

solution is (0.5, 1 )

Answer:

-26

Step-by-step explanation:

Dropping here means subtracting. That means that we calculate:

Answer:

A

Step-by-step explanation:

I = Prt = r * Pt

divide Pt from both side we get

I/(Pt) = r

Answer:

a

Step-by-step explanation:

I = Prt ( isolate r by dividing both sides by Pt )

[tex]\frac{I}{Pt}[/tex] = r , that is

r = [tex]\frac{I}{Pt}[/tex] → a

Answer:

11) x = -1

12) y = 8

13) j = 155

14) g = -4

15) x = 18

Step-by-step explanation:

11) 2(x - 3) = -8

x - 3 = -4

x = -4 + 3 = -1

12) y + 3 = -2y + 27

3y = 24

y = 8

13) 2j - 3 + 3j = 2 (341 + 45)

5j - 3 = 2(386)

j = 155

14) 2(g + 1) = 3(g + 2)

2g + 2 = 3g + 6

-4 = g

15) 25 = 4/3 x + 1

25 - 1 = 4/3 x

24 = 4/3 x

18 = x

x = 18

g = -4

Answer:

Solution: x = 8, y = -24 or (8, -24)

Step-by-step explanation:

Given the systems of linear equations, 4x + y = 8 and -3x - y = 0:

We can find the solution by using the elimination method since the variable, y, has opposite signs. Simply add the two equations and solve for the value of x:

Equation 1:   4x + y = 8

Equation 2:  -3x - y = 0

    4x + y = 8  

+  -3x - y = 0

      x  =  8

Next, substitute the value of x = 8 into either one of the equations to solve for y:

4x + y = 8

4(8) + y = 8

32 + y = 8

Subtract 32 from both sides:

32 - 32 + y = 8 - 32

y = -24

Therefore, the solutions to the given systems of linear equations are:

x = 8, y = -24  or (8, -24)
