Answer:

15\ units

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and the corresponding angles are congruent

In this problem Triangles PQT and RQS are similar by AA Similarity Theorem (The three angles are congruent)

therefore

\frac{12}{16}=\frac{x}{20}\\ \\x=12*20/16\\ \\x=15\ units

Using a system of equation, we have that:

a)

  • x, which is the cost of on-site service.
  • y, which is the cost of at-store service.
  • z, which is the cost of by-mail service.

b)

The system is:

x = 3y

z = y - 10

15x + 40y + 5z = 3100

c)

The cost of one on-site repair service is of $90.

Item a:

The variables are:

  • x, which is the cost of on-site service.
  • y, which is the cost of at-store service.
  • z, which is the cost of by-mail service.

Item b:

On-site service costs <u>3 times as much as at-store service</u>, thus:

x = 3y

By mail service costs <u>$10 less than at-store</u>  service, thus:

z = y - 10

Last week, the shop completed <u>15 services on-site, 40 services at-store, and 5 services by mail for total sales of $3100</u>, thus:

15x + 40y + 5z = 3100

The system is:

x = 3y

z = y - 10

15x + 40y + 5z = 3100

Item c:

  • The cost of one on-site repair service is x.
  • First, replacing the first two equations into the third, we find y, and then with it we find x.

15x + 40y + 5z = 3100

15(4y) + 40y + 5(y - 10) = 3100

60y + 40y + 5y = 3150

105y = 3150

y = \frac{3150}{105}

y = 30

Then

x = 3y = 3(30) = 90

The cost of one on-site repair service is of $90.

You would put they y intercept on 0 and then go up 1 to the right 5
continue that till the is no more graph
the go down 1 to the left 5
continue that too

After 2 weeks, a plant is 9 centimeters tall. After 5 weeks, it has grown to 15 centimeters. If the plant grows at constant rate
Reil [10]

Answer:

y = 2x + 5

Step-by-step explanation:

First, find the slope using rise over run, (y2 - y1) / (x2 - x1)

With this information, we can create 2 points: (2, 9) and (5, 15)

Plug in the points:

(15 - 9) / (5 - 2)

6 / 3

= 2

Plug in the slope and a point into y = mx + b, and solve for b:

y = mx + b

15 = 2(5) + b

15 = 10 + b

5 = b

Plug in the slope and b into the equation:

y = 2x + 5 is the equation of the line
