Answer:
6x +2x
Step-by-step explanation:
when the number= x, you can just form the equation as per usual. 6x = a number times 6; 2x = a number times 2.
x is used bc the number is an unknown value. only x can be used bc it is stated the same number. hsing different alphabets such as y or z indicates the unknown value ia different.
We know, y - y1 = m(x - x1)
y - 9 = 2(x - 3)
y - 9 = 2x - 6
y = 2x + 3
In short, Your Answer would be Option B
Hope this helps!
Subtract 4 from each side
Divide both sides by 5
Take square root of both sides
Add 3 to both sides
The function modelled by the height (x) of the tree is as follows:
y - 180 = (368 - 180)/(7 - 3) (x - 3)
y - 180 = 47(x - 3) = 47x - 141
y = 47x - 141 + 180 = 47x + 39
Therefore, after 10 years, the tree will be 47(10) + 39 = 470 + 39 = 509 cm tall
