Answer:
A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system.
X/35 = 7
we can multiply 35 on both sides
x = 245
Answer:
<u>x < -12</u>
Step-by-step explanation:
-2/3x > 8
-2/3x * (-3/2) < (-3/2)
cancel the common factor of 2
-x/3*-3<8* (-3/2)
Multiply
x<8 * (-3/2)
Simplify
x < 4 * -3
Multiply
x<-12
-2/3x > 8
= x < -12
If <span>σ = the standard deviation and we know the deviation is 15 we can set his up like the following:
</span><span>σ = √v
</span><span>15 = √v
Square both sides:

</span>
