\text{The slope-intercept form:}\ y=mx+b\\\\\text{We have:}\ m=4\\\\\text{then}\ y=4x+b\\\\\text{The line passes through point (6; -4). Substitute:}\\\\(6;-4)\to x=6;\ y=-4\\\\-4=4\cdot6+b\\-4=24+b\ \ \ |-24\\b=-28\\\\\text{therefore:}\ y=4x-28
\text{substitute}\ (2;\ r)\to x=2;\ y=r\\\\r=4\cdot2-28=8-28=-20

Liam, Sarah and Emily shared some money in the ratio 2:3:5. Liam got £30 less than Sarah.
blondinia [14]

The number representing Liam's share is 2; for Sarah's share, it is 3. The difference of those is 1, so each 1 unit of share must be £30, the difference between the amount Sarah got and the amount Liam got.

Emily got 5 shares or £30 × 5 = £150.

Find the value of x in the figure below. <br> 26<br> 56<br> Х
SashulF [63]
The answer is 30

Explanation:

So all of the angles in a triangle add up to 180 degrees and so if you split the triangle into separate triangles then you can add up the angles that are known and subtract from 180 to get the size of the missing angle e.g 90 + 56 = 146, 180 -146 = 34 for the other triangle 90 + 26 = 116, 180 - 116 = 64 and so 64 - 34 = 30

fiasKO [112]
<h3>Answer:  7/19</h3>

Explanation:

There are 7 blue marbles out of 4+7+8 = 11+8 = 19 total

The probability of selecting blue is therefore 7/19

We cannot reduce 7/19 any further because 7 and 19 have no common factors other than 1.
