F(x) = 2/3x + 1

This is in the slope-intercept form of an equation for a line. 
Which is written as this: (Note f(x)= is the same as saying y= in this case)

y = mx + b

M is our slope. Slope is the RISE over the RUN

In other words it is y/x
For this graph y represents distance, and x represents time. (Life Tip: TIME is almost ALWAYS the X value) 

In this case M = 2/3

So her speed is: 
2 units/3 units

B is the y-intercept. The y-intercept is where the X-value equals 0. So, (0,y). Because the y-intercept is distance she should have a y-intercept of 0. (The origin) because that would mean at the start of the race she had no distance (aka she was at the starting line).

Because her y-intercept (b) = 1 she did have a head start.

Here are both the answers at once to make it easier for you: 
Speed (Replace Units with whatever units you were given. Distance Units go on top. Time units on bottom. Example: Meters/Second))
2 units/3 units

Did she have a head start? (Unit being whatever distance unit you were given) 
Yes, 1 unit.

Add -15.9 to both sides so it’ll look like 3.7x=18.87

Which of the following describes the end behavior of<br> f(x) = (1/2)^x
NARA [144]

Answer:

as x approaches infinity, f(x) approaches 0

as x approaches -infinity, f(x) approaches infinity

Step-by-step explanation:

we can observe that 1/2 < 1 and since it's being exponentiated, the f(x) gets smaller and smaller as x gets bigger.

For example, f(0) = 1, f(1) = 1/2, f(2) = 1/4

so, as x approaches an infinitely large number, f(x) gets closer and closer to zero.

this is the opposite as x approaches a negatively large number. following exponential rules, 1/2^(x) = 2^x for all x < 0. therefore as x approaches negative infinity, f(x) approaches infinity.

in this case, f(-1) = 2, f(2) = 4, f(3) = 8

) Una compañía invierte $15,000 al 8% y $22,000 al 9%. ¿A qué tasa debe invertir
Anna35 [415]

Usando proporciones, hay que los $12,000 restantes deben ser investidos a una tasa de 11%.

<h3>¿Qué es una proporción?</h3>

Una proporción es una fracción de la cantidad total.

De las dos primeras inversiones, el ingreso es dado por:

0.08 x 15000 = $1,200.

0.09 x 22000 = $1,980

T = 1200 + 1980 = $3,180

Por la tercera inversión, busca-se un retorno de 4500 - 3180 = $1,320.

De esa forma, la tasa x es la seguiente:

12000x = 1320

x = 1320/12000

x = 0.11.

Los $12,000 restantes deben ser investidos a una tasa de 11%.
