Gavin and Caleb go to the movie theater and purchase refreshments for their friends. Gavin spends a total of $22.25 on 2 bags of

gavmur [86]

Answer:

Drinks = 6.75

Popcorn= 1

Step-by-step explanation:

Let the popcorn = P

Let the drink = D

2*P + 3*D = 22.25 multiply this equation by 6

12*P + 4D = 39.00

12P + 18D = 133.5 Subtract these two equations

- 14D = - 94.50 Divide by -14

-14D/-14 = -94.5/-14 Do the division

D = 6.75

=========================

12P + 4D = 39 Substitute for D

12P + 4*6.75 = 39 Combine

12P + 27 = 39 Subtract 27 from both sides

12P + 27-27=39-27 Collect like terms

12P = 12 Divide by 12

12P/12 = 12/12

P = 1 Answer

Use the relationship between the sine and cosine functions to fill in each blank .

rjkz [21]

Answer:

sin(12°)

Step-by-step explanation:

Because sine and cosine are cofunctions, we can use the relation sin(90° - θ) = cosθ to show that cos(78°) = sin(90° - 78°) = sin(12°)

What is the equation, in slope-intercept form, of the line that is perpendicular to the line y – 4 = –(x – 6) and passes through

Mkey [24]

Let's convert the equation in point-slope form to slope-intercept form.

y - 4 = -(x - 6)
Multiply everything out.
y - 4 = -x + 6
Add 4 to both sides.
y = -x + 10

To be perpendicular, the slope of the new has to be the reciprocal of the other line. To slope in this equation is -1/1. To get the reciprocal, flip the numerator and denominator and change the sign too.

-1/1 becomes 1/-1, and changes to 1/+1, or 1.

y = x + b

Input the coordinate point and solve for b.

-2 = -2 + b
Add 2 to both sides.
0 = b

y = x
