Number of hours: n

<span>The cost of renting a bike for the first hour is $7:
n=1→f(n)=f(1)=$7

</span>He is charged $2.50 for every additional hour of renting the bike:
f(n)=f(n-1)+2.50, for <span>n ≥ 2
</span>
f(1)=7; f(n)=f(n-1)+2.50, for <span>n ≥ 2 (sixth option)
</span>
f(n)=f(1)+2.50(n-1)
f(n)=7+2.50(n-1)
f(n)=7+2.50n-2.50
f(n)=2.50n+4.50 (fifth option)

Answers:
Fifth option: f(n)=2.50n+4.50, and
Sixth option: f(1)=7; f(n)=f(n-1)+2.50, for <span>n ≥ 2</span>

Solve the system of equations algebraically. Verify your
xz_007 [3.2K]

Answer:

The solution is the point (0.5,-3)

Step-by-step explanation:

we have

y=4x-5 ----> equation A

y=-3 ----> equation B

Solve the system by substitution

Substitute equation B in equation A

-3=4x-5

Solve for x

Adds 5 both sides

-3+5=4x

2=4x

Divide by 4 both sides

x=0.5

therefore

The solution is the point (0.5,-3)

<em>Verify your  answer using the graph</em>

using a graphing tool

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (0.5,-3)

therefore

The solution is the point (0.5,-3)

The triangles below are similar. Triangle S R P. Angle S is 54 degrees, R is 41 degrees, P is 85 degrees. Triangle X Y Z. Angle
rewona [7]

Answer:

The similarity statements that describes the relationship between the two triangles are

Triangle S R P is similar to triangle X Z Y.

Triangle R S P is similar to triangle Z X Y.

Triangle R P S is similar to triangle Z Y X.

Step-by-step explanation:

Given:

Triangles below are similar,

In ΔSRP

∠S = 54 ° , ∠R = 41° , ∠P = 85°

In ΔXYZ

∠X = 54 ° , ∠Z = 41° , ∠Y = 85°

Solution:

If two triangles are similar then their corresponding angles are Equal.

When the two triangles are Similar then their Vertices are correspondence to each other. the correspondence of vertices are as

For, Δ SRP ~ Δ XZY

S ↔ X        ∠S ≅ ∠X = 54°

R ↔ Z        ∠R ≅ ∠Z = 41°

P ↔ Y        ∠P ≅ ∠Y = 85°

The true statement  

Triangle S R P is similar to triangle X Z Y.

Triangle R S P is similar to triangle Z X Y.

Triangle R P S is similar to triangle Z Y X.

  • Triangle P R S is similar to triangle X Y Z,

Not correct it should be

Triangle P R S is similar to triangle Y Z X,

  • Triangle P S R is similar to Triangle Z Y X

Not correct it should be

Triangle P S R is similar to Triangle Y X Z.

  • Triangle S P R is similar to triangle X Z Y

Not correct it should be

Triangle S P R is similar to triangle X Y Z
