Answer:
Yes is a solution
Step-by-step explanation:
3h = 2(h+2)-1
We replace h=3
3*3 = 2(3+2) - 1
Solve
9 = 2(5)-1
9 = 10 - 1
9 = 9
Is correct h= 3
when we manage to find the same value on both sides of equality it means that the value entered is a possible option

Answer:
y=0.5x+8
Step-by-step explanation:
Use the formula for the equation of a line y=mx+c where m is the slope and c is a number.
To find the slope, take two points (x₁,y₁) (x₂,y₂) and put them into the slope equation m=(y₂-y₁)/(x₂-x₁):
We can take two points from the graph: (2,9) (4,10)
m=(y₂-y₁)/(x₂-x₁)
m=(10-9)/(4-2)
m=1/2 or 0.5
Now sub this value in for m and our formula looks like this:
y=0.5x+c
To find the value of c, sub in one of the points, eg. (4,10)
y=0.5x+c
10=0.5(4)+c
10=2+c
c=8
So now that we now m and c, our equation is complete :D
y=0.5x+8
Answer: 1.2metres
Step-by-step explanation:
Five years ago, tree was 4.9m
Today, tree is 6.1m
Subtract 4.9m from 6.1m
Tree has grown by 1.2m
