Answer:

x=15 y=24

Step-by-step explanation:

This is because the rule is x goes up 3 y goes up 4

(9,12)->(x,20)

it skips one, so instead of adding 3 we add six

x=15

(15,20)->(18,y)

you follow the rule and 4.

Y=24

What is an equation of the line that passes through the points (0, -1)(0,−1) and (6, 1)(6,1)?

horrorfan [7]

$slope = y2 - y1 \div x2 - x1$

$1 - - 1 \div 6 - 0$

$2 \div 6$

$1 \div 3$

$y = mx + c$

$1 = 1 \div 3 \times 6 + c$

$1 = 2 + c$

$c = 3$

$y = 1 \div 3x + 3$

Answer:

Hope this helps!!!!!!

Mark Brainlest!!!!!!!!!!

Step-by-step explanation:

Mark and Henry win some money and share it in the ratio 1:3. Mark gets £9. How much did Henry get?

Ratio = 1 : 3

Let Mark's share be 1x = x

and Henry's share be 3x

We know that Mark gets £9

So,

1x = x = £9

Then 3x = £(3 * 9) = £27

HENCE,

Mark's share = £9

Henry's share = £27

Total money = Mark's share + Henry's share = £9 + £27 = £36
