This is a line in the form y = mx + b, where b is the y intercept. In your equation above, 3 is the slope, the m value, and -6 is the y-intercept, the b value.
Let w represent the number of weeks passed.
The amount of money Ed saved is 6w - 1 (I'm subtracting the one dollar that he owes to someone)
His sister saved 6w + 2.66 (I'm adding the money she already saved).
What value of w makes both expressions equal?
We need to solve the equation 6w - 1 = 6w + 2.66
Let's solve it.
If we subtract 6w from both sides, we get -1 = 2.66
So, there is no solution. They will never have saved the same amount.
This makes sense because they started out with different amounts of money saved, but they are saving at the same rate.
Answer:
twelve, 12 and just draw twelve dots
Z = (x - mean) / SD = (79 - 70) / 3 = 3
<span>P (Z > 3)? = 1 - F (z) = 1 - F (3) = 0.00135</span>
Answer:
85
Step-by-step explanation:
2x+192=180
2x= -12
x= -6
-6+91= 85
