Answer:

Photo Lab: $y$ =3.20x +8

Specialty Photos: $y$ =2.60x + 10

Step-by-step explanation:

At the Photo Lab, the cost is $3.20 per roll plus 8 per print.

Therefore, the cost of developing a roll of film is:

$y$ =3.20x +8

At Specialty Photos the cost is $2.60 per roll plus 10 per print.

Therefore, the cost of developing a roll of film is:

$y$ =2.60x + 10

(x-19)/2=(x-7)/1 step by step please

Maksim231197 [3]

Answer:

X=-5

Step-by-step explanation:

Since anything divided by one is still that number, then (x-7)/1 becomes x-7. So our equation now looks like:

(X-19)/2=(x-7).

Multiplying both sides by 2, we get

X-19=2x-14

Adding 19 to both sides:

X=2x+5

Subtract 2x from both sides:

-x=5

Multiplying both sides by -1, we get:

X=-5

Which of the following equations is on the same path as x=2-3t, y=7-6t?

Svet_ta [14]

Answer:

C. $y = 3+2\cdot x$

Step-by-step explanation:

Let be the parametric equations $x = 2-3\cdot t$ and $y = 7 - 6\cdot t$ , we need to clear $t$ and eliminate it afterwards to obtain a function of the form $y = f(x)$ :

$x = 2 - 3\cdot t$

$3\cdot t = 2 - x$

$t = \frac{2}{3}-\frac{1}{3}\cdot x$ (1)

$y = 7 - 6\cdot t$

$6\cdot t = 7 - y$

$t = \frac{7}{6} - \frac{1}{6}\cdot y$ (2)

By (1) and (2):

$\frac{2}{3}-\frac{1}{3}\cdot x = \frac{7}{6}-\frac{1}{6}\cdot y$

$4 -2\cdot x = 7 - y$

$y = 3+2\cdot x$

Hence, the correct answer is C.
