\frac{ - 2x}{2}  =  - 2 \\  \frac{ - 2x}{2}  \times (2) =  - 2 \times (2) \\  - 2x =  - 4 \\  \frac{ - 2x}{ - 2} =  \frac{ - 4}{ - 2}   \\ x = 2

The scatter plot below shows the relationship between the length (x) in meters and mass f(x) in kg of a marine animal
Vlad [161]
F(x) = -9 + 10.3x probably.
It's definitely not the first or last option as they have negative gradients (i.e. negative x-coefficient) and so represent a negative correlation. The data given tells us there is a positive gradient and so a positive correlation.
It could be the second option as the second and third are not so vastly different but I would go for the third because it appears to most closely fit the data pattern.

A car is driving away from a crosswalk. The formula d = t2 + 2t expresses the car's distance from the crosswalk in feet, d, in t
alukav5142 [94]

Answer:

8 feet per second.

Step-by-step explanation:

We have been given that a car is driving away from a crosswalk. The formula d=t^2+2t expresses the car's distance from the crosswalk in feet, d, in terms of the number of seconds, t, since the car started moving.

We will use average change formula to solve our given problem.

\text{Average change}=\frac{f(b)-f(a)}{b-a}

\text{Average change}=\frac{d(5)-d(1)}{5-1}

\text{Average change}=\frac{(5)^2+2(5)-((1)^2+2(1))}{4}

\text{Average change}=\frac{25+10-(1+2)}{4}

\text{Average change}=\frac{35-3}{4}\\\\\text{Average change}=\frac{32}{4}\\\\\text{Average change}=8

Therefore, the the car's average speed over the given interval of time would be 8 feet per second.

Arrange the list of numbers in increasing order.. . 2/5, 4/9, 3/7
Allushta [10]
The numbers given in the question are 2/5, 4/9 and 3/7. We have to take them to decimal form for arranging the numbers in increasing order.
2/5 = 0.40
4/9 = 0.44
3/7 = 0.43
Then, the increasing order of the numbers would be 
2/5 < 3/7 < 4/9
