Answers

First, lets put this into slope intercept form

3x + 2y = -6

2y = -3x - 6

y = -3/2x - 3

The y intercept is (0, -3)

To find the x intercept we set the new equation to zero and solve

0 = -3/2x - 3

+3             +3

(2)3 = -3/2x(2)

6 = -3x

6/-3 = -3x/-3

-2 = x

The x intercept is (-2,0)

Therefore, your intercepts are:

y-int. = (0,-3)

x-int. = (-2,0)

Ross has a season ticket.

In 2013 the season ticket cost £65.
In 2014 the cost of the ticket was increased by 8%.
In 2015 the cost of the ticket was increased by a further 5%.

Calculate the cost of the season ticket after the two price increases.

Answers

Answer:

£73.71

Step-by-step explanation:

Let's compute first for the cost of the ticket in 2014. Let x be the increase in the cost of the ticket. If the cost of the ticket is 8% of £65, then the expression should be like this:

x = 65 x 8%x = 65 x 0.08x = £5.2

Let's add £5.2 to £65 ⇒ £5.2 + £65 = £70.2

The cost of the season ticket in 2014 is £70.2.

Next, we'll have to compute the cost of the ticket in 2015. Let y be the increase in cost of the ticket. If the cost of the ticket is 5% of £70.2, then the expression should be like this:

y = 70.2 x 5%y = 70.2 x 0.05y = £3.51

Let's add £3.51 to £70.2 ⇒ £3.51 + £70.2 = £73.71

The cost of the season ticket in 2015 is £73.71. This is also the cost of the season ticket after two price increases.

5) In August, Yesenia was 4 feet tall. Each month since August, she has consistently grown 0.25 inc
How tall is Yesenia t months after August?

Answers

Answer:

Yesenia is 0.25t+4 inches tall after August.

Step-by-step explanation:

Given that:

Height of Yesenia in August = 4 feet tall

Growth rate since August = 0.25 inches

Number of months after August = t

According to given statement;

Height after August = Growth rate * Number of months + Height in August

Height after August = 0.25t + 4

Hence,

Yesenia is 0.25t+4 inches tall after August.

Michele wanted to measure the height of her school's flagpole to place on the ground 35 ft from the flagpole then walks backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft away from the mirror using similar triangles, find the height of the flagpole to the nearest of a foot

Using similar triangles

= Let the height of the flagpole be represented as h.

h/35 =5/12

We cross Multiply

35 x 5 = 12h

12h = 175

h = 175/12

h = 14.583333333 feet

Approximately to the nearest foot is
