3. Yes the cost of each item is proportional because in each pack each t-shirt cost $2.33. You can check that by dividing the amount of money each pack cost by the amount of shirts in each pack. For example the pack of 3 is $7, so 7/3 = $2.33. The pack of 5 cost $11.65, so 11.65/5 = $2.33. And the pack of 7 cost $16.31, so 16.31/7 = $2.33

4) Yes, it is proportional because each x is being squared or multiplied by it’s self.

Answer:

∠1 = 82°

Step-by-step explanation:

Sum of angles in a triangle = 180°

Now,we have two sides as 49° and 49°.

The third angle is denoted as ∠1.

Thus;

∠1 + 49 + 49 = 180

∠1 = 180 - (49 + 49)

∠1 = 180 - 98

∠1 = 82°

If (fog)(x)=7x-1/3 and f(x)=3x+5,find g(x),where g(x)is linear<br>

Svetach [21]

Answer: $g(x) = \dfrac73x-\dfrac{16}{9}$

Step-by-step explanation:

Given: $(fog)(x)=7x-\dfrac13$

$f(x)=3x+5$

and g(x) is linear.

A linear function is of the form : $y= mx+c$

Let $g(x)= mx+c$

Then, $(fog)(x)=f(g(x))= f(mx+c)$

$= 3(mx+c)+5\\\\=3mx+3c+5$

Comparing it with the original (fog)(x), we get

$3mx+3c+5=7x-\dfrac{1}{3}$

Comparing coefficient of x and constants separately

$3m=7,\ \ \ \ 3c+5=-\dfrac13\\\\\Rightarrow\ m=\dfrac{7}{3},\ \ \ \ 3c =-\dfrac{1}{3}-5\\\\\Rightarrow\ m=\dfrac{7}{3},\ \ \ \ 3c =-\dfrac{16}{3}\\\\\Rightarrow\ m=\dfrac{7}{3},\ \ \ \ c =-\dfrac{16}{9}$

So, $g(x) = \dfrac73x-\dfrac{16}{9}$
