A local yoga studio
Andrews [41]

Answer:

Let's call the first studio, yoga studio A.

Let's call the second studio, yoga studio B.

The equations:

Yoga Studio A: y=10x+55

Yoga Studio B: y=12.5x+25

So, for 12 classes:

Yoga Studio A: y=10(12)+55, y=175

Yoga Studio B: y=12.5(12)+25, y=175

These two numbers are equal, so Griffin is right.

For 10 classes:

Yoga Studio A: y=10(10)+55, y=155

Yoga Studio B: y=12.5(10)+25, y=150.

These two numbers are not equal, so Gigi is wrong.

Let me know if this helps!

Which function describes the arithmetic sequence shown?<br><br> 1, 7, 13, 19, 25, 31, ...
Taya2010 [7]

Answer:

a(n) = a(1) + 6(n -1)

Step-by-step explanation:

The common difference here is 6.  1 + 6 = 7; 13 + 6 = 19; and so on.

Thus, the function in question is a(n) = a(1) + 6(n -1).

Functions f(x) and g(x) are shown below:
AlekseyPX
Consider f(x) = -4(x - 6)² + 3
This is a parabola with vertex at (6, 3).
Because the leading coefficient of -4 is negative, the curve opens downward, and the vertex is the maximum value.

Answer: Maximum of  f(X) = 3

Consider the function g(x) = 2 cos(2x - π) + 4
The maximum value of the cosine function is 1.
Therefore the maximum value of g(x) is
2*1 + 4 = 6

Answer: Maximum of g(x) = 6

0.7 (3s + 4)-1.1s = 7.9
vichka [17]

Answer:

s = 5.1

Step-by-step explanation:

0.7 (3s + 4)-1.1s = 7.9\\

Multiply both sides of the equation by 10

0.7\left(3s+4\right)\cdot \:10-1.1s\cdot \:10=7.9\cdot \:10\\\\= 7\left(3s+4\right)-11s=79\\

Expand

\mathrm{Expand\:}7\left(3s+4\right)-11s:\\\quad 10s+28

Subtract 28 from both sides

10s+28-28=79-28

Simplify

10s=51

Divide both sides of the equation by 10

\frac{10s}{10}=\frac{51}{10}

Simplify

s=\frac{51}{10}\\\\Decimal = 5.1
