Answer: (0, 10)

Step-by-step explanation:

The given expression is in the standard form of linear equations: <u>Ax + By = C</u>, where A and B are constants.

The definition of y-intercept is <u>the point that intersects with the y-axis</u>, meaning that the [x] value of the point will be zero.

To find the y-intercept of an equation, <u>substitute the [x] variable with 0</u>, as mentioned above, the [x] value of a y-intercept is 0.

7x+y=10\\

7(0)+y=10

0+y=10

y=10

As we find the [y] value is 10, while the given [x] value is 0, therefore, the y-intercept of 7x+y=10 is \boxed{(0,10)}.

Hope this helps!! :)

9. The ticket at right has a perimeter of 42 cm.
Liula [17]

Perimeter simply represents the sum of all side lengths of a shape. The length of the missing side of the ticket is 5 cm; the length of gold line on each ticket is 20 cm, and 2 bottles of gold ink are required to draw gold lines on 200 tickets.

I've added the image of the ticket as an attachment.

(a) The missing side length

From the attachment, the 4 unknown side lengths are equal. Represent this side length with L.

So, we have:

Perimeter =2\times 11 + 4 \times L

This gives

2\times11 + 4 \times L = 42

22 + 4 \times L = 42

Collect like terms

4 \times L = 42-22

4 \times L = 20

Divide both sides by 4

L =5cm

(b) The length of the gold lines

There are 4 slant lines and the length of one of the slant lines is 5 cm (as calculated above).

So, the length of the gold line is:

Gold = 4 \times L

Gold = 4 \times 5cm

Gold = 20cm

(c) The number of gold ink bottles.

n = 200 --- number of tickets

The length of all gold line in the 200 tickets is:

Length = 200 \times Gold

Length = 200 \times 20cm

Length = 4000 cm

Length = 4000 \times 0.01m ---- convert to meters

Length = 40m

Given that:

Bottle = 20m --- 1 bottle for 20 m

The number of bottles (n) is:

n = \frac{Length}{Bottles}

n = \frac{40m}{20m}

n = 2

Hence, 2 bottles of gold ink are enough.
