I just looked up the question Bc I didn’t know if there was more to it but, Helen bought 15 chips and 8 pretzels. I hope this helps!!
The Pythagorean trigonometric identity is a trigonometric identity expressing the Pythagorean theorem in terms of trigonometric functions. Along with the sum-of-angles formulae, it is one of the basic relations between the sine and cosine functions.
Answer:
(2,-2)
Step-by-step explanation:
To solve this using substitution you would take your second equation and plug it in for y of the first equation (4x-10= -3x+4). You then would add the 10 over (4x= -3+14). Next you add the 3x over(7x=14). Finally divide both sides by 7, which should give you x=2. Now all you have to do is plug the two in for x in one of your equations (which ever equation you prefer) (y=-3(2)+4). Solve the equation and you will then have the answer to y, which you can then put into a point.
Answer:
5/4
Step-by-step explanation:
An probability can not be more than 1.
The range from probability is from 0-1.
When 0, is none and 1 is all.
5/4 is more than 1, so it is not an possible probability.
