Answer:
y = -13x - 1
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Slope <em>m</em> = -13
y-intercept <em>b</em> = -1
<u>Step 2: Find Equation</u>
- Substitute in variables [Slope-Intercept Form]: y = -13x + -1
- Simplify: y = -13x - 1
just multiply 45 time 31!
C, 1/3
Every time the number is reducing by 1/3
Hope this helps
Step-by-step explanation:
b = age of Bailey
c = age of Celine
b + c = x
c = b + 8
so, using that identity in the first equation
b + b + 8 = x
2b + 8 = x
or, to go "after" c (Celine) :
b = c - 8
c - 8 + c = x
2c - 8 = x
2c = x + 8
c = (x + 8)/2
in x years c will have increased to c+x, and b to b+x.
so,
b + x + c + x = x + 2x = 3x
and
2c - 8 = 3x
2c = 3x + 8
c = (3x + 8)/2

Answer:
x = 6
Step-by-step explanation:
The sum of segments is used:
EF +FG = EG
3x +(5x +16) = 11x -2 . . . . substitute given expressions
8x +18 = 11x . . . . . . . . add 2
18 = 3x . . . . . . . . subtract 8x
6 = x . . . . . . divide by 3
The value of the variable is 6.
__
<em>Check</em>
The segment lengths are ...
EF = 3x = 3·6 = 18
FG = 5x+16 = 5·6 +16 = 46
EG = 11x -2 = 11·6 -2 = 64 = 18+46 . . . answer is correct
