Which graph show the solution set for -5/2x -3&lt;2
Oliga [24]
It is less than two, so it has to be going in the direction that is below two. There is a line under the < so the dot should be filled. The answer is the third from the top. “Choice C”

The mass of a sunfish and a giraffe, since birth, are represented by the following tables:
Lyrx [107]

Answer:

Giraffe is linear. Sunfish is exponential.

Step-by-step explanation:

For the sake of clarity the first matrix, for Giraffe.

In this Giraffe the angular coefficient is not exact, but quite close.

m varies from 102 to 99

Time (months) and Mass (Kg)

\begin{bmatrix}0 &63  & \\ 5 &165&\\10&264\\15&368\\20&468\\ \end{bmatrix}

Geometrically, solving just plotting these two parameters as coordinate points.

(0, 63), (5,165), (10,264)...(20,468) We have a linear function.

2. Sunfish

\begin{bmatrix}0 &3.5\\ 5 &19.3\\10&106.5\\15&587.5\\20&3240.5\\ \end{bmatrix}

Exponential functions are given according to y=ax^n  let's call n, by t. and find the other variables

y=ax^t

3.5=a(x)^t \therefore 3.5=a(x)^0 \\Finding\: x\\\\t= is\: the \:time \: in \:the\: table\\19.3=3.5(x)^1 \therefore 5.514=x  \therefore x=5.541\\\\m_{3}=3.5(2.348)^3\\\\So:\\y=3.5(5.514)^t

y=3.5(5.514)^3 \therefore y=586.77

An exponential function fits the best.

SpyIntel [72]

Answer:

Option 1

Similar triangles have proportional sides.

This means that the sides of ΔABC must have the same ratio to the sides of ΔSTR, ΔLKJ, or ΔDEF.

The base angle of ΔABC is 6 and therefore the base angle of the similar triangle should be divisible by 6. This leaves ΔSTR out

Continue the process with the other sides:

side BC is 4 units meaning the corresponding side of either ΔDEF or ΔLJK with have to be divisible by 4. in JKL the corresponding side KL is 9 units and not divisible by 4. Therefore, DEF is the correct answer since its corresponding sides are proportional
