Answer:
A.
Step-by-step explanation:
We have x in exponent, so it is an exponential function.
Exponent is negative, so is is an exponential decay.
Answer:
Step-by-step explanation:
(2,1), (-2,-1)
slope(m) = (-1-1) / (-2 - 2) = -2/-4 = 1/2
parallel lines will have the same slope
y = mx + b
slope(m) = 1/2
(-4,8)...x = -4 and y = 8
now sub and find b, the y int
8 = 1/2(-4) + b
8 = -2 + b
8 + 2 = b
10 = b
so ur equation is : y = 1/2x + 10 <==
Answer:
The mean will reduce
Step-by-step explanation:
The total amount of money for the ten days divided by number of days will give mean 1, M₁
Removing the value for day seven will reduce the sum of money as it will be for 9 days only.In finding the mean, you will divide by 9 days to get mean M₂
Mean M₂ < M₁
Answer:
Refer below
Step-by-step explanation:
Installation fee equation will be added onto the original equation
So g = base cost + percent cost + $100
(Cost of carpet) ---> g = $7.5x + ($7.5x * 0.05) + $100
Plug in 150 into the formula that gives you $1281.25
Make sure to study these, questions like these will for sure strengthen your math skills
Y=mx+b is what I learned and point slope is y-y1=m*x-x1
