Answer:
Step-by-step explanation:
In y = mx + b form, the slope can be found in the m position and the y intercept can be found in the b position.
4x - 2y = -6
-2y = -4x- 6
y = (-4/-2)x -(6/-2)
y = 2x + 3....slope here is 2, and y int is 3
3x + y = 3
y = -3x + 3.....slope here is -3, and y int is 3
B. slopes are different, y intercepts are the same
Answer:
It would be $62.62 because basically you want to do 52.50 times 1.25
Answer:
Step-by-step explanation:instead, try making the subscripts and superscripts stand out:
n-1
a = a * r
n n-1
Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.
1
So, a = -3 and r=2.
1
So the formula for this geometric sequence is
n-1
a = -3*2
n
Answer:
B. 95% confident the average concentration of PCBs in the water supply is between 2.9 ppb and 3.5 ppb
Step-by-step explanation:
You are given the total number of samples, the concentration of lead, and the standard deviation. The standard deviation represents how inaccurate the estimation of the concentration of lead in the drinking water. This means that there can only possibly be a 0.3 ppb error in the estimation. 3.2-0.3=2.9, and 3.2+0.3=3.5
