Which graph shows the solution to the following inequality?

Answers

Answer:

We are given a inequality with the equality sign in terms of variable 'r' as:

$-2r+3\geq 19$

Now we find the solution of the following inequality by solving for 'r'.

We subtract 3 from both side of the inequality to obtain:

$-2r+3-3\geq 19-3\n\n-2r\geq 16$

Now we multiply both side by "-1" to obtain:

$2r\leq -16$

Now on dividing both side of the inequality by 2 we obtain:

$r\leq -8$

Hence, the solution of the inequality are the set of all the points on the number line which are less than equal to -8.

i.e. the shaded region is to the left of -8 and closed circle at -8.

i.e. the solution is: (-∞,-8].

A)The equation of a line β is 2x-3y=6find the gradient of β
b) find the equation of the line which is parallel to β and passes through the point (6,9)

Answers

Answer:

a) 2/3

b) $y = (2)/(3) x + 5$

Step-by-step explanation:

b) From my previous answer...

Since parallel lines have the same gradient,

the gradient of the line is 2/3 too.

Thus, m= 2/3.

y= 2/3x +c

Now substitute a coordinate into the equation to find c, the y-intercept.

When x=6, y=9,

9= (2/3)(6) +c

9= 4 +c

c= 9 -4

c= 5

Thus the equation of the line is y= 2/3x +5.

Find the diagonal of a cube if its side equals 5. When applicable, simplify radicals and show all of your work.

Answers

Answer:

7.0711

Step-by-step explanation:

The diagonal of a square of side of length a is a√2.

Here, the length of the square is given as: 5 units.

So, the length of the diagonal is 5√2 units.

But √2 = 1.4142.. (Approx.)

So, the length of the diagonal, d = 5 X 1.4142.

This is equal to 7. 0711.

So, the answer is 7.0711 units.

Which list orders the numbers from least to greatest? |-2.4|,|-1.5|,-2 1/2|,|-3|, |-1 1/8|

Answers

Answer:

the answer is D

Step-by-step explanation:

Sorry if i get it wrong

Final answer:

The ordered list from least to greatest using the absolute values would be: |-1 1/8|, |-1.5|, |-2 1/2|, |-2.4|, |-3|.

Explanation:

The student is asking to order a series of numbers from least to greatest. The numbers given are in absolute values. Absolute value refers to the distance of a number from zero, disregarding whether it is negative or positive. Therefore, the |-2.4| signifies the absolute value of -2.4, which is 2.4. Similarly, the other numbers convert to 1.5, 2.5, 3, and 1.125 respectively.

To answer this question, we must understand that the smaller the absolute value, the closer the number is to zero. Hence, the order from smallest (or least) to largest (or greatest) would be: |-1 1/8|, |-1.5|, |-2 1/2|, |-2.4|, |-3| .
