S=number of swim lessons

A.) The equation is 237 = 402-15s

237 = 402 - 15s
-402 = -402
-165 = -15s
/-15= /-15
11 = s
B.) 11 swim lessons.

C.) 0 = 237 - 19s
-237= -237
-237 = -19s
/-19 = /-19
12.47368 = s
She can pay for 12 more swim lessons and will have some money left in her account.

(WILL GIVE BRAINLIEST) Which of the following exponential functions goes through the points (1, 6) and (2, 12)?
olganol [36]

Answer:

\boxed{a. \: f(x) = 3(2)x} \: is \: correct

Step-by-step explanation:

if \: the  \: points \: are \:  (1, 6) \:  and  \: (2, 12) \to \\ then \to \\ m =  \frac{12 - 6}{2 - 1}  =  \frac{6}{1}  \\  \boxed{m = 6} \\ y - 6 = m(x  - 1) \\ y = 6x - 6 + 6 \\ y = 6x = (3)(2)x \\ but \: y = f(x) \to \: hence \to \\ \boxed{ f(x) = 3(2)x}

what is an equation of the line that is parallel to the line with y=-.60x+2 and passes through the point (10,-10)
sp2606 [1]

y = -0.60x - 4

because the slope stays the same because it is parallel and the y intercept for the new equation ends up being -4

Dexter has 83 tiles left over from tiling his bathroom floor and he would like to use them to tile the front entrance of his hou
creativ13 [48]

Answer: [0, 396]

Step-by-step explanation:

The domain is the acceptable values of x in the function.  In this case, x = t, the number of tiles.  If you think about it, the minimum number of tiles is 0 (you can't have a negative number of tiles), and the maximum number of tiles is 44 (you only have 44 tiles).  So, the domain for this function is from 0 to 44.

0 to 44 written in interval notation is [0,44].

The range is the acceptable values of y in the function.  In this case, y = A, the area given.  A(t) = 9t, so you can use the acceptable values of t to get the range.  Again, the minimum area is 0 because you can't have negative area. To find the maximum area, plug in the maximum number of tiles: 9.

A(t) = 9t

A = 9(44)

A = 396

With the maximum number of tiles, 44, the area you get is 396 cm².  Therefore, the acceptable values of A are from 0 to 396.

0 to 396 written in interval notation is [0, 396].
