Answer:
b = 2a + 3
Step-by-step explanation:
Here, we want to write an expression for b in terms of a
Mathematically, the formula for the slope of a line is
m = (y2-y1)/(x2-x1)
m is 2
(x1,y1) = (-1,1)
(x2,y2) = (a,b)
Substituting these values
2 = (b-1)/(a-(-1))
2 = b-1/a + 1
2(a + 1) = b-1
2a + 2 = b- 1
2a + 2 + 1 = b
b = 2a + 3
Answer:
Its B 0.454554555
Step-by-step explanation:
it has a pattern which is repeating. So its known as rational number..
From the above expression we get,
=》x + y = 7 - [1]
=》3x - 2y = 11 - [2]
now, let's solve :
multiplying [1] by 3
=》3x + 3y = 21
=》 3x - 2y = 11
subtracting
now, subtracting [2] from [1]
=》3x + 3y - 3x + 2y = 21 - 11
=》5y = 10
=》y = 2
now, plugging the value of y as 2 in equation [1]
=》x + y = 7
=》x + 2 = 7
=》x = 5
So, value of :
Answer:

Greg is selling games for $10 each, while Martin is selling games for $12 each.
120 divided by 10 is 12, 60 divided by 6 is 10
Answer:
58
Step-by-step explanation:
The sum of the exterior angles ALWAYS measures 360 degrees, meaning that 90+38+3x+x = 360
This means that 128 + 4x =360, meaning that 4x = 232.
That makes x = 58
