Answer: b ≥ -3

<u />

Step-by-step explanation: B has to be at least -3, which means that it cannot be less thsn -3. however, it can be greater than. That is where the greater than symbol comes from. B can be equal to -3 because the lowest you can go is -3 (The number itself still counts) So, thats why the inequality in word form would be that be is greater than or equal to -3

Triangle X Y Z is shown. The length of side X Y is (9 n + 12) feet and the length of side X Z is (15 n minus 6) feet. Angles X Y

zmey [24]

Answer:

$n = 3$

$XY = 39$

$XZ = 39$

Step-by-step explanation:

Given

$XY = 9n + 12$

$XZ = 15n - 6$

Solving (a): n

To solve for n;

We make use of

$XY = XZ$

Substitute values for XY and XZ

$9n + 12 = 15n - 6$

$9n - 15n = -12 - 6$

$-6n = -18$

Divide through by -6

$n = 3$

Solving (b) XY

$XY = 9n + 12$

Substitute 3 for n

$XY = 9 * 3 + 12$

$XY = 27 + 12$

$XY = 39$

Solving (c): XZ

$XZ = XY$

$XZ = 39$

assume a telephone signal travels through a cable at two-thirds the speed of light. how long does it take the signal to get from

Helen [10]

The time length for a sign to travel from new york to Miami is 0.089 seconds.

We understand the speed of mild in miles per 2nd is 186,000.

the rate of smartphone signal is 2/3rd is =2/3rd of 186,000

= 124,000 miles in line with 2nd

Distance among Miami and new york is given to be 1100 miles.

So, the time required to journey the phone signal from new york city to Miami is = distance ÷ speed

= 1100 ÷ 124,000

=0.089 seconds

Time taken via the telephone sign from Miami to new york is 0.089 seconds.
