The correct option is D. In fact, you can evaluate this function at every possible input x.
All this function does is:
- Take a number x
- Add 6
- If the result is negative switch the sign, otherwise keep it as it is
As you can see, you can perform these operations regardless of the input x.
Answer:
Nicole is correct
Step-by-step explanation:
by multiplying the first equation by 3 it becomes:
3x + 6y =21
this can cancel the -3x in the second equation when adding them together
and
are vectors and:
![\vec{u}=14j=0i+14j=[0,14]\\\\ \vec{v}=i+4j=1i+4j=[1,4]](https://tex.z-dn.net/?f=%5Cvec%7Bu%7D%3D14j%3D0i%2B14j%3D%5B0%2C14%5D%5C%5C%5C%5C%0A%5Cvec%7Bv%7D%3Di%2B4j%3D1i%2B4j%3D%5B1%2C4%5D)
is the dot product or scalar product, so:
![\vec{u}\cdot\vec{v}=[0,14]\cdot[1,4]=0\cdot1+14\cdot4=56](https://tex.z-dn.net/?f=%5Cvec%7Bu%7D%5Ccdot%5Cvec%7Bv%7D%3D%5B0%2C14%5D%5Ccdot%5B1%2C4%5D%3D0%5Ccdot1%2B14%5Ccdot4%3D56)
Correct answer is A.
Base= 2(area)/height <- that is the formula for finding the base of a scalene triangle
Answer:
C) z = 1/2
Step-by-step explanation:
4z + 5 = 7
4z = 2
z = 1/2
