The equation of a function<br>y = 2/3x+1/3 find the value of y<br>when x = -3<br>when x = 1 1/2​
kirill [66]

Answer:

y = \frac{-5}{3}\\\\y = \frac {4}{3}

Step-by-step explanation:

y = \frac{2}{3} x + \frac{1}{3}\\\\when \ x = -3 \\\\y = \frac{2}{3}(-3) + \frac{1}{3} = -2 + \frac{1}{3} = \frac{-6 + 1}{3}= \frac{-5}{3} \\\\When \ x = 1 \frac{1}{2} = \frac{3}{2}\\\\y = \frac{2}{3} \times \frac{3}{2} + \frac{1}{3} = 1+ \frac{1}{3} = \frac{3 + 1}{3}= \frac{4}{3} \\\\

A Table showing Freezing Temperatures in degrees with 2 columns and 6 rows. The First row, F, has the entries, negative 13, nega
Yuki888 [10]

Answer:

5F + -9  C= 160       39°F = 3.9

Step-by-step explanation:

A Table showing Freezing Temperatures in degrees with 2 columns and 6 rows. The First row, F, has the entries, negative 13, negative 4, 5, 14, 23. The second column, C, has the entries, negative 25, negative 20, negative 15, negative 10, negative 5.

The table shows temperatures below freezing measured in different units. Complete the equation in standard form to represent the relationship between F, a temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius.

5F + -9 C = 160

39°F = 3.9°C rounded to the nearest tenth of a degree

Shrinivas deposited $1300 in an account which pays 8% annual interest, compounded continuously. How long will it take to reach $
sertanlavr [38]

Answer: a. 12.4 years

Step-by-step explanation:

Function to represent exponential growth continuously:

A=A_0e^{rt}  ...(i)

, where A_0 = initial amount, r= rate of interest ( in decimal) , A = Amount after t years.

As per given , we have

A_0=\$1300\\\\r=8\%=0.08\\\\ A=\$3500

To find : t

Put all values in (i) ,

3500=(1300)e^{0.08t}\\\\\Rightarrow\ 2.6923077=e^{0.08t}

Taking natural log on both sides

\ln(2.6923076)= 0.08t\\\\\Rightarrow\ 0.99039867=0.08t\\\\\Rightarrow\ t=\dfrac{0.99039866}{0.08}=12.37998325\approx12.4

Hence, it would take <u>12.4</u> years.

so, the correct option is a. 12.4 years .
