Answer:

x = (b-c)/a

Step-by-step explanation:

ax + b = c

Subtract b from each side

ax+b-b = c-b

ax = b-c

Divide by a

ax/a = (b-c)/a

x = (b-c)/a

Hey!


To solve this equation, we'd first have to apply the distributing rule to this equation.

<em>Original Equation :</em>
( 3a - 2 )^{2}

<em>New Equation {Changed by Applying the Distribution Rule} :</em>
( 3a )^{2} - 2 · 3a · 2 + 2 ^{2}

And now we simplify.

<em>Old Equation :</em>
( 3a ) ^{2}  -2 · 3a · 2 + 2 ^{2}

<em>New Equation {Old Equation Simplified} :</em>
9a ^{2} - 12a + 4

<em>So, the equation (3a - 2) ^{2} simplified is</em>  9a ^{2} - 12a + 4.

Hope this helps!

The midpoint of the line segment from P1 to P2 is (-6,5). If P1 = (-7,8), what is P2?
kipiarov [429]
You can determine midpoint by
x-midpoint = (x₁ + x₂)/2
y-midpoint = (y₁ + y₂)/2

Given from the question
x-midpoint = -6
x₁ = -7
y-midpoint = 5
y₁ = 8

Asked from the question
(x₂, y₂)

Solution
Find x₂, input the value of x₁ and x-midpoint to the formula
(x₁ + x₂)/2 = x-midpoint
(-7 + x₂)/2 = -6
-7 + x₂ = -6 × 2
-7 + x₂ = -12
x₂ = -12 + 7
x₂ = -5

Find y₂, input the value of y₁ and y-midpoint to the formula
(y₁ + y₂)/2 = 5
(8 + y₂)/2 = 5
8 + y₂ = 5 × 2
8 + y₂ = 10
y₂ = 10 - 8
y₂ = 2

Answer
P₂ = (-5,2)

Identify the 27th term of an arithmetic sequence where a1 = 38 and a17 = -74.
makkiz [27]
Arithmetic sequence:
an=a1+(n-1)d
a_{17}= a_{1}+16d&#10;&#10;-74=38 + 16d&#10;&#10;16d=-74-38&#10;&#10;16d=-112
d=-112/16=-7
a_{27}=a_{1}  + 26d=38+26*(-7)=38-182=-144
