Answer:

Option d: {d | d ≤ 6} is the correct answer

Step-by-step explanation:

Given inequality is:

3(2d-1)\geq 4(2d-3)-3\\Expanding the terms\\6d-3 \geq 8d-12-3\\6d-3 \geq 8d-15\\Adding\ 3\ to\ both]\ sides\\6d-3+3\geq 8d-15+3\\6d\geq 8d-12\\Subtracting\ 8d\ from\ both\ sides\\6d-8d \geq 8d-12-8d\\-2d\geq -12\\Multiplying\ both\ sides\ by\ -1\\2d\leq 12\\Dividing\ both\ sides\ by\ 2\\d \leq 6

Hence, option d: {d | d ≤ 6} is the correct answer ..

Solve number 8 please
beks73 [17]

Answer:

see explanation

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k )² = r²

where (h, k ) are the coordinates of the centre and r is the radius

given

x² + y² - 8x + 8y + 23 = 0

collect the x and y terms together and subtract 23 from both sides

x² - 8x + y² + 8y = - 23

using the method of completing the square

add ( half the coefficient of the x / y terms )² to both sides

x² + 2(- 4)x + 16 + y² + 2(4)y + 16 = - 23 + 16 + 16

(x - 4)² + (y + 4)² = 9 ← in standard form

with centre = (4, - 4 ) and r = \sqrt{9} = 3

this is shown in graph b

3/n of 32 is 24 solve for n
Sonbull [250]

Answer:

n=4

Step-by-step explanation:

Of means multiplying so,

\frac{3}{n}×32=24

Multiply by n on both sides to get rid of the n denominator.

3×32=24n

Simplify the equation.

96=24n

Divide by 24.

n= 4
