This is a linear equation because it has an x and y within the expression without exponents or other complex operators. We can rearrange and simplify the equation into slope-intercept form.

$y-2=4(3x+5)\\y-2=12x+20\\y-2+2=12x+20+2\\y=12x+22$

This linear equation follows the form y=mx+b where m is the slope and b is the y-intercept. For this function, m=12 and b=22. This is not a proportional relationship because the function's y-intercept is something other than 0.

What is 36kg in the ratio 7:2

babymother [125]

Answer:

28 Kg : 8 Kg

Step-by-step explanation:

Sum the parts of the ratio, 7 + 2 = 9 parts

Divide 36 Kg by 9 to find the value of one part of the ratio.

36 Kg ÷ 9 = 4 Kg ← value of 1 part of the ratio, thus

7 parts = 7 × 4 Kg = 28 Kg

2 parts = 2 × 4Kg = 8 Kg

36 Kg in the ratio 7 : 2 = 28 Kg : 8 Kg
