Answer:
The 1st one on the right is a function
1) The supplement of 72° is 180°-72° = 108° . (bottom // with right secant)
2) (3z + 18)° = 108° ( in a para llelogram opposite angles are equal)
Then 3z+18 = 108 and 3z° = 90° → z = 30°
3) (3y)° = 108° (vertical angles) , 3y° = 108 and y = 36°
4) 3y = x° (corresponding angles) but 3y = 108, then x = 108°
(Mind you I am calculating the ∠ x, y, and z. To find the angles of the parallelogram replace x,y and z by their respective values
The amount of money the family still needs to save is $2236.
<h2>Linear system</h2>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
Their vacation savings account currently has a balance of $2,764.
The family would like to have at least $5,000.
<h3>To find </h3>
The amount of money the family still needs to save.
<h3>How to find the amount of money the family still needs to save?</h3>
Forming the equation, we get
Let x be the amount needed to save. then
x + 2764 ≥ 5000
On simplifying, we get
x + 2764 ≥ 5000
x ≥ 5000 - 2764
x ≥ 2236
Thus, the amount of money the family still needs to save is $2236.

The amount flora has is 45.
The answer is C. The rate the population increases. The 960 in the equation represents the population at a certain number of weeks which is x. The starting population describes the quantity 15. The number of weeks that have passed is described as the 6 weeks.
The equation would be described as: f(x) =15*(2^x) and f(x) =960
