Answer:
x+y=37-------(1)
5.5x+13.5y=355.5-----(2)
Put x=37-y in eqn 2
5.5(37-y)+13.5y=355.5
203.5-5.5y+13.5y=355.5
8y=152
y=19
x=18
Step-by-step explanation:
Answer:
y = ( 5 / 9 )x + 30
Step-by-step explanation:
y - y1 = m ( x - x1 )
m = 5 / 9
y - ( 5 ) = ( 5 / 9 ) [ x - ( - 45 ) ]
y - 5 = 5 / 9 ( x + 45 )
y - 5 = ( 5 / 9 )x + 25
y = ( 5 / 9 )x + 30
Answer:
d. y= 5x+18
Step-by-step explanation:
y=mx+b is slope intercept form
Now we plug in the information given to us which is slope(m) is 5 and a point (x,y) which is (2,28).
So by substituting we get 28=5(2)+b
simplify to 28=10+b and when we subtract 10 from both sides to isolate 'b', we get that b = 18.
So now we use the values of slope(m) and the y-intercept(b) to write the equation:
y=5x+18
