Consider the coordinates of the given points

(- 4, - 8 ), (0, 0 ), (1, 2 ), (3, 6 )

It should be noted in each case that the y-coordinate is twice the value of the x- coordinate, hence equation is

y = 2x → D

Simplify: -0.8b+4.1c-(-3.2b)-0.1c

BigorU [14]

[ Answer ]

$\boxed{2.4b \ + \ 4c}$

[ Explanation ]

Simplify: -0.8b + 4.1c - (-3.2b) - 0.1c

-----------------------------------

Apply Rule: - (-a) = a

-0.8b + 4.1c + 3.2b - 0.1c

Group Like Terms

-0.8b + 3.2b + 4.1c - 0.1c

Add Similar Elements: -0.8b + 3.2b = 2.4b

2.4b + 4.1c - 0.1c

Add Similar Elements: 4.1c - 0.1c = 4c

2.4b + 4c

$\boxed{[ \ Eclipsed \ ]}$

The number of species of coastal dune plants in australia decreases as the latitude, in °s, increases. There are 34 species at 1

Bas_tet [7]

We have been given that the number of species of coastal dune plants in Australia decreases as the latitude, in °s, increases.

Further we know that there are 34 species at 11°s and 26 species at 44°s.

We can express the given information at two ordered pairs as shown below:

$(n,l)=(11,34)\text{ and }(n,l)=(44,26)$

Let us find slope of the line through these points:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{26-34}{44-11}=\frac{-8}{33}=-0.2424$

Therefore, we can write the equation of line in slope intercept form as:

$n=-0.2424l+b$

Where b is the y intercept, and we can find its value using one of the two points.

$34=-0.2424(11)+b\\34=-2.67+b\\b=34+2.67=36.67$

Therefore, the required equation of the linear function is:

$n=-0.2424l+36.67$

City L has a temperature of −3 °F. City M has a temperature of −7 °F. Use the number line shown to answer the questions: Number

Alik [6]

-3 > -7
u have to remember, with negatives, the larger number is smaller in value.

when u plot these numbers on the number line, the number that is farthest to the left is less then...the number that is farthest to the right is greater then.

-3 is warmer because it is closer to zero then -7.
