The equation that must be true regarding the function is a. f(–3) = –5
<h3>
How to explain the information?</h3>
The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function?
a. f(–3) = –5
b. f(–3, –5) = –8
c. f(–5) = –3
d. f(–5, –3) = –2
The question is what does the point (-3, -5) correspond to on the graph of the function.
If we have a point on a graph in the Cartesian coordinate system then that point consists of coordinates (x, y). In other words, y=f(x) and x so (x, f(x)) where x is a x-coordinate and y=f(x) is y-coordinate.
Hence if we have a point (-3, -5) the corresponding coordinates are x=-3 and y=f(x)=-5.
Therefore the correct answer is f(-3)=-5.

12 mixed nuts packs
Explanation:
The box weighs 16 1/2 ounces
1 mixed nut = 1 3/8 ounces
let the number of fruit mixed nut in the box = y
1 mixed nut = 11/8 ounces
y = 33/2 ounces
cross multiply:


For trapezoid, the area = (upper base + lower base) * height / 2
So area = (12 + (2*2 + 12) ) *13 / 2 = 182
X = adult tickets
y= child tickets
x + y = 11
44.95x + 34.95y = 434.45
-44.95x - 44.95y = -494.45
-10y = -60
y = 6 child tickets
x + 6 = 11
x = 5 adult tickets
