The correct answer is True

Explanation:

In mathematics, equations are mathematical statements that include a set of elements that are said to be equal, for example, x + 5 = 4 - 1. These statements are used to find unknown values that are generally represented by letter x, for example by solving the equation previously presented you can find the value of x.

Equations are widely used at school as part of mathematics subject, but besides this, the main purpose of writing and then solving a equation is to find unknown values in real problems or situations either in daily life or other fields such as engineer, for example if you buy a set of items and do not know the value of one of them but know the total price of them you can use an equation to know the unknown value. Thus, it is true the purpose of solving equations is to solve application problems.

Part A: Eveline rented a car at $180 for 4 days. If she rents the same car for 9 days, she has to pay a total rent of $325. Writ

QveST [7]

Answer:

Step-by-step explanation:

Part A

We will use the slope intercept form of the line and then convert later.

Equation

y = mx + b is the general form

Givens

Two data points

(4,180)

(9,325)

Solution

325 = 9x + b

<u>180 = 4x + b</u> Subtract

145 = 5x Divide by 5

145/5 = 5x/5 Do the division

29 = x This represents the cost / day

180 = 4x + b Substitute x = 29 to find b

180 = 4*29 + b Combine

180 = 116 + b Subtract 116 from both sides.

180 - 116 = b

64 = b

Solution for y = mx + b

y = 29x + 64

In Standard form this is

- 29x + y = 64 But the first number must be plus

29x - y = - 64 <<<< Answer A

Part B

y = 29x + 64

f(x) = 29x + 64

Part C

The graph is shown below. Various points are filled in using y = 29x + 64. The y intercept is (0,64) which is labeled. Let x = 1 , 2, 3, 4, ... 10 (which is arbitrary). This may be more easily done on a spreadsheet if you know how to use one to make graphs.
