4. they are supplementary

5. ∠1+∠2=180°=∠2+∠3

6. ∠1+∠2=180°=∠2+∠3

∠2 are same in both side so ∠1=180°-∠2 =∠3=180°-∠2

WITCHER [35]

Answer:

Cost to a rent a snorkel=\$ 12                ,           Cost on 10 rent  snorkel =\$ 120

Step-by-step explanation:

Given,

Tourist spend on rent snorkel and fin=\$ 168

10 snorkel and 12 pairs of fin

Let the cost to  rent a snorkel be =\$x

and cost of a pair of fin is =\$y

x=3y            (given condition)

10x+12y=168

10\times 3y+12y=168

30y+12y=168

42y=168

y=168/42

y=4

Cost of a pair of fin=  y=\$ 4

x=3y

x=3\times 4

x=12

Cost of rent a snorkel=\$ 12

Total cost of a rent snorkel

=10\times 12

   =\$ 168

ohaa [14]

Answer:

The y-intercept is 40. This is the cost of registration ⇒ last answer

Step-by-step explanation:

* Lets explain how to solve the problem

- Patrick wanted to gather data about the cost of joining a community

 pool in his area

- He plotted the data and determined that the average community

 pool membership cost consists of a one-time registration fee and

 a monthly fee

∴ The cost consists of two parts:

# Part A: one-time registration fee, it is a fixed amount not depend on

  any other condition

# Part B: monthly fee, it depends on the number of months

- He modeled that by the equation y = 15 x + 40, where

# y is the cost for the membership

# 15 is the monthly fee

# x is the number of months

# 40 is the one-time registration

- The form of the equation is y = mx + c, where c is the y-intercept

∴ The y-intercept in the equation y = 15 x + 40 is 40

∴ The y-intercept is the one-time registration fee

* The y-intercept is 40. This is the cost of registration

Solve the following system of equations by substitution. 3x + 2y = -12 x = 2 A. (2, -9) B. (-2, -3) C. (3, 2) D. (2, 3)
Brilliant_brown [7]
Plugging it in, we get (3)(2)+2y=-12 and 6+2y=-12. Subtracting 6 from both sides, we get -18=2y and dividing by 2 we get y=-9  to get (2, -9) since x is first in the pair
