Answer:
y = 2x - 3
Step-by-step explanation:
So since we have to put it in y = mx + b form
Subtract 2x from both sides
-y = -2x + 3
Divide both sided by -1
y = 2x - 3
Answer:
Heyy
Step-by-step explanation:
Lets Price of article is 100
Dep value after 1 year =100−
100
100×10
= 90
Dep. value after 2 year =90−
100
90×10
=81
Dep. value after 3 years =81−
100
81×15
=68.85
Total Dep. =100−68.85 = 31.15%
4y + 8x = 112
V = x*x*y= x^2y
y + 2 x = 28
y = 28 - 2x
V = x^2 (28-2x) = 28 x^2 - 2 x^3
Answer:
4 : 7
Step-by-step explanation:
Given 2 similar figures the if the ratio of perimeters = a : b
The the ratio of areas = a² : b²
Here
ratio of areas = 16 : 49 , then
ratio of perimeters = : = 4 : 7
