Easy. your starting point is going to be at -2 on the y-axis. then from that point (-2) you're going to go down 1 and then over 2. then draw a straight line through those two points. The line should be a negative line.
Answer:
Step-by-step explanation:
Hi,
The two numbers should be 12 and 30. 12=2x2x3 while 30=2x3x5.
Their HCF is 2x3=6 and their LCM is 2x3x2x5. Because of their HFC, we know that they are both multiple of 6. Also, the question says they both are GREATER than 6, so they can’t be 6 but are 6 times “something”. Thanks to the LCM, we know that “something” is equal to 2 for the first number and to 5 for the second one, the numbers hence being 12 and 30.
I hope this helps. If I was not clear enough or if you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
Answer:
2x³- 2px² + p + 2
First plug in x = -3
2(-3)³- 2p(-3)² + p + 2
According to PEMDAS, we should solve the exponents first.
(-3)³ = -27
(-3)² = 9
2(-27) - 2(9)p + p + 2
Now multiply.
-54 - 18p + p + 2
Now combine the variables and constants.
-17p - 52
This is the simplified expression.
If it is an equation, then it would equal 0.
-17p - 52 = 0
To solve for p, add 52 to both sides.
-17p = 52
Now isolate the p by dividing by -17.
p = -52/17 or -3.0589
In your graphing calculator, you can press 2nd then cos to create cos^-1 and then press 0.5967.
You’re basically doing arccos(0.5967) or cos^-1(0.5967)
Remember to put your calculator into radian mode first.
Your answer will be 0.9314138684 in radian
For degrees it would be 53.36608364
