1250+27.50x=1400+20x

Mathematics
1 answer:
never [62]4 years ago
5 0

Answer:

x = 20

Step-by-step explanation:

Simplifying

1250 + 27.50x = 1400 + 20x

Solving

1250 + 27.50x = 1400 + 20x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-20x' to each side of the equation.

1250 + 27.50x + -20x = 1400 + 20x + -20x

Combine like terms: 27.50x + -20x = 7.5x

1250 + 7.5x = 1400 + 20x + -20x

Combine like terms: 20x + -20x = 0

1250 + 7.5x = 1400 + 0

1250 + 7.5x = 1400

Add '-1250' to each side of the equation.

1250 + -1250 + 7.5x = 1400 + -1250

Combine like terms: 1250 + -1250 = 0

0 + 7.5x = 1400 + -1250

7.5x = 1400 + -1250

Combine like terms: 1400 + -1250 = 150

7.5x = 150

Divide each side by '7.5'.

x = 20

Simplifying

x = 20

> or = i.e. \ge

and it could also be:

< or = i.e. \le

Take for instance:

Let's see if this is better
1: Substitute 0 for x in the equation → y = f(0) = a^0 = 1
    Therefore (0, 1) is a point on the graph

2: Substitute 1 for x in the equation → y = f(1) = a^1 = a
    Therefore (1, a) is a point on the graph

3: y = f(x) = a^x is an exponential function which has a horizontal asymptote of y = 0 (equation for the x - axis) ... The reason it is above the x-axis is because there is no negative coefficient on "a" to reflect it below the x-axis
