Step-by-step explanation:
x = by - 3/2
x + 3/2 = by
y = x/b + 3/(2b)
now compare this to the first equation :
y = 2x + 3
the system has infinite solutions, if both equations are actually identical.
and they are only identical, if b = 1/2
y = x/(1/2) + 3/(2 × 1/2) = 2x + 3
So in a 8 hour workday he would make $72... 9x8=72
now 155-72= 83
83/6= a little over 13
so he would at least have to make 14 deliveries
:)
7x^2 + 3
7(4)^2 + 3
7(16) + 3
112 + 3
115.
Answer:
35 degrees is correct(I might be wrong though.)
Step-by-step explanation:
Since this is a vertical angle question,3x° = 70 + x°
Therefore,3x - x = 2 x,making 2x=70.
so x= 70÷ 2=35. Again- I might be wrong-
