The <em><u>correct answer</u></em> is:
b) As the number of days increase, the number of years increase.
Explanation:
The way this is written, the independent variable is the number of days and the dependent variable is the number of years. The slope would be the number of years' increase per day.
If the independent and dependent variables are switched, the number of years would be independent and the number of days would be dependent. The slope would be the number of days' increase per year.
Both of these slopes involve comparing time in two different formats; the slope is still meaningful for both.
Answer:
Let us consider the expression:
(1)
Now, the quotient of power rules says that the numbers that have same base can be find by subtracting if powers are with same sign
And adding if powers are with opposite sign.
We will solve equation (1) by this quotient of power rule.
So, it can be rewritten as:

.
Answer:
152
Step-by-step explanation:
Let x be the number of children tickets sold
2x+x=228
combine like terms
3x=228
x=76
adult tickets is two times the amount of x
2x=152
Answer:
The answer is 5n-2 so the 3rd choice.
Answer:
y = -6x + 7.5
Explanation:
To find <u>perpendicular bisector</u> equation:
Given points: B(-2, 1), C(4, 2)
First find slope:


Then the <u>perpendicular slope</u> will be <u>negatively inverse</u>.

Then find the <u>mid point coordinates</u> between BC:



Then find equation:
y - yₘ = m(x - xₘ)
y - 1.5 = -6(x - 1)
y = -6x + 6 + 1.5
y = -6x + 7.5
