Read the sentence and write the equation:
x = the input #

The sum of the cube of the input = x^3
and 4 times the square of the input = 4x^2 and
the difference of the product of 5 and the number decreased by 7 = 5(x - 7)

Now put the terms together:
x^3 + 4x^2 - 5(x - 7)

Express x in terms of a and b: b−7x=a−b
pav-90 [236]
B - 7x = a - b
Subtract b from both sides.

-7x = a - 2b
Divide both sides by -7.

x = \frac{-a + 2b}{7}

So to find the balance use this equation.

Balance = Credit- Debit


 In other words, to find BALANCE... You Subtract Debit from Credit

Whats my debit? 29$
Whats my balance? Lets find out! How? Well, lets subtract my credit (84) from my debit (29).

84-29= 55

Find the equation for the line that passes through the point (−2,0), and that is perpendicular to the line with the equation 2/3
patriot [66]

Answer:

y = 3/2 x + 3

Step-by-step explanation:

2/3 x + y = -14/3

y = -2/3 x − 14/3

The slope of this line is -2/3.  So the perpendicular slope is the opposite of the inverse:

m = -1 / (-2/3)

m = 3/2

We know the slope of the line and a point on the line, so using point-slope form:

y − 0 = 3/2 (x − (-2))

Simplifying into slope-intercept form:

y = 3/2 (x + 2)

y = 3/2 x + 3
