Answer:
<h2>A. Switch the inequality sign</h2>
Step-by-step explanation:
When multiplying, you must switch the inequality sign. This is also true when dividing.
EXAMPLE 1:
-4r < -21
Note: We reversed the inequality sign when we divided by -4
r > 5 1/4
EXAMPLE 2:
x/-5 <u>></u> 7
Note: We reversed the inequality sign when we multiplied by -5
x <u><</u> -35
I'm always happy to help :)
I’m confused on what it is asking
On a clock one rotation around the clock for 12 hours is 2pi, since the clock rotates for 36 hours that means that the clock rotates around the clock 3 times since 36/12=3. So 2pi*3= 6pi. Therefore the hour hand will rotate 6pi radians in 36 hours
We have that
x²<span> − 2x − 3 = 0
Step 1
</span>isolate the variable terms
<span>x² - 2x = 3
</span>Step 2
complete the square
<span>x² - 2x + 1² = 3 + 1² </span>
<span>(x-1)² = 4
</span>
the answer is the option (x-1)² = 4
