Answer:
See below
Step-by-step explanation:
<h3>Part A</h3>
Standard form is Ax + By = C
<u>x - price of adult tickets, y - price of child tickets, the equation in the standard form is:</u>
- 15x + 9y = 90 ⇒ 5x + 3y = 30
<h3>Part B</h3>
<u>y-intercept is obtained when x = 0</u>
- 15*0 + 9y = 90
- 9y = 90
- y = 10
It represents the amount of child tickets if no adult tickets sold
<u>x-intercept is obtained when y = 0</u>
- 15x + y*0 = 90
- 15x = 90
- x = 6
It represents the amount of adult tickets if no child tickets sold
<h3>Part C</h3>
<u>Converting the equation into slope-intercept form of y = mx + b</u>
- 5x + 3y = 30
- 3y = -5x + 30
- y = -5/3x + 30/3
- y = -5/3x + 10
<h3>Part D</h3>
- The slope is -5/3. It represents the negative ratio of ticket prices
When you divide a whole number by a decimal less than 1 the quotient is greater than the whole number because the that is how many times the quotient is a part of the whole number. For instance, you divide 100 by 4, you will get a quotient of 25. There are 4 parts of 25 to be equal to 100.
Answer:
t = 6 years
Step-by-step explanation:
Use the simple interest formula: i = prt, where p is the principal, r is the interest rate as a decimal fraction, and is the elapsed time, in years.
Here we want to know how long it will take for the interest alone to reach $449.40. We first solve i = prt for t, obtaining t = i/(pr).
Here, the length of time is t = ($449.40) / (0.06*$1498.00). This works out to
t = 5.9947, or approximately 6 years.
t = 6 years
Option A is correct i.e 2x+7 is a factor of trinomial 
Step-by-step explanation:
We need to find the factor of the trinomial
Factoring:
So, the factors are (2x+7) and (5x-4)
So, Option A is correct i.e 2x+7 is a factor of trinomial
