Step 1

<u>Find the slope of the function f(x)</u>

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

Let

A(-6,0)\\B(0,4)

substitute

m=\frac{4-0}{0+6}

m=\frac{4}{6}

m=\frac{2}{3}

Step 2

<u>Find the y-intercept of the function f(x)</u>

The y-intercept is the value of the function when the value of x is equal to zero

in this problem the y-intercept of the function is the point B(0,4)

so

the y-intercept is equal to 4

Step 3

Verify each case  

we know that

the equation of the line into slope-intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

<u>case A) </u>f(t)=t+4

In this case we have

m=1\\y-intercept=4

therefore

the function of case A) does not have the same slope as the function f(x)

<u>case B) </u>f(t)=t-6

In this case we have

m=1\\y-intercept=-6

therefore

the function of case B) does not have the same slope and y-intercept as the function f(x)

<u>case C) </u>f(t)=\frac{2}{3}t+4

In this case we have

m=\frac{2}{3}\\y-intercept=4

therefore

the function of case C) does have the same slope and y-intercept as the function f(x)

<u>case D) </u>f(t)=\frac{2}{3}t+6

In this case we have

m=\frac{2}{3}\\y-intercept=6

therefore

the function of case D) does not have the same  y-intercept as the function f(x)

therefore

<u>the answer is</u>

f(t)=\frac{2}{3}t+4

Complete the table by writing the fraction as a decimal and as a percent
aniked [119]

Answer:

Decimal = 0.6

Percentage = 60%

Step-by-step explanation:

Let's simplify the fraction.

\frac{120}{200}  =  \frac{60}{100}  = 0.6

Hence the Decimal is 0.6

To express 120/200 in percentage , we have to multiply the fraction with 100.

\frac{120}{200}  \times 100 =  \frac{120}{2}  = 60\%

Hence the percentage value is 60%
