Answer:
y =
x + 7
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (10,12) ← 2 ordered pairs from the table
m =
=
= 
y =
x + c ← is the partial equation
to find c substitute any ordered pair into the partial equation
using (6, 10 ), then
10 = 3 + c ⇒ c = 10 - 3 = 7
y =
x + 7 ← linear equation
Answer:
-3/7
Step-by-step explanation:
Answer:
Its about 678.584
Step-by-step explanation:
First plug in your given info so put 6 for the r and 6 for thr h. the r stands for radius and the h stands for hight. Then solve for 6 squared which is just 6*6 which is 36 then multiply that by 6 to get 216. then multiply 216 by pie to get your answer.
If you need further explanation just comment on this for help
3(x+4)= 3x+12
3x+12+x+3+x=5x + 15
5x+15=180
5x=180-15
5x=165
x=165/5
x= 33min
mowing the grass = 3(x+4)
= 3(33+4)
=99+12
=111 min mowing grass
