Derrick's parents are finalizing a budget for his college expenses. His first year of college will cost $8,000, and his
pychu [463]
The first answer



Step by step

His first year costs $8,000
So our total amount to start with is $8,000

His second year will cost 12% more than his first so $8,000 • 1.12 = $8,960
Our total is now $16,960

His third year will again will be 12% more than his last year so $8,960 • 1.12 = 10,035.2
Our total is now $26,995.2

His last year will be 12% more than his previous year so $10,035.2 • 1.12 = $11,239.42
Our final total is $38,234.62
Which rounded equals $38,235

Write an equation in standard form for the line that has undefined slope and passes through (-6, 4)
Nikitich [7]

Answer:

y = ix + 6i + 4

Step-by-step explanation:

Since the line has undefined slope or indefinite slope we connote that the slope is (i)

Slope(m) of straight line = change in y ÷ change in x

Taking another  point (x,y) on the line:

i = \frac{y - 4}{x - -6}

i = \frac{y - 4}{x + 6}

Cross multiplying gives;

y - 4 = ix + 6i

y = ix + 6i + 4

A college basketball team offers season passes for $85, but you pay $4.45 for a program

<h3>What are basic linear equations?</h3>

Moving the variables to one side of the equation and the numeric portion to the other allows us to solve a linear equation with one variable. As an illustration, the equation x - 1 = 5 - 2x can be resolved by transferring the numerical components to the right side of the equation while leaving the variables on the left. Therefore, we receive x + 2x = 5 + 1. Thus, 3x Equals 6. As a result, x = 2. The formula for a two-variable linear equation is Ax + By + C = 0, where A and B are the coefficients, C is a constant term, and x and y are the two independent variables, each with a degree of 1. A linear equation involving two variables, for illustration, is 7x + 9y + 4 = 0.

Consequently, you would multiply $9.45 and $4.45 by the same number (I selected 9 because there are only one or two possible answers), then add $85 to the result for the $4.45 amount.

9.45 x 9

= 85.05

4.45 x 9

= 40.05 +85

= 125.05
