Answer:
b, c
Step-by-step explanation:
The factor (x+7) is common to both numerator and denominator. The function can be simplified by cancelling that factor.
y = (x -3)/(x -9) . . . . . . x ≠ -7
The restriction x ≠ -7 is put on the simplified function because the original function is undefined there. The denominator factor x+7 makes the denominator 0 at that point.
The point at x=-7 is called "hole" in the graph. A properly drawn graph will show the function is undefined there (has a hole).
__
The denominator of the simplified function is zero when x=9. This means there is a vertical asymptote at x=9.
__
The ratio of the highest-degree terms of the numerator and denominator will tell you the end behavior of the function — its value when x is large. Here, that ratio is y = x/x = 1. This represents a horizontal asymptote at y=1. The function approaches this line as x gets large, but never reaches it.
The appropriate descriptors are ...
Asymptote: x=9, y=1Hole: x=-7

Stella has five times as many books as Tina. If Stella gave 16 books to Tina, they would each have the same number of books. How many books does Stella have?
Answers
Answer:
40 books
Step-by-step explanation:
s = Stella's books
t = Tina's books
Given:
s = 5t
s - 16 = t + 16
Plug first equation into second:
5t - 16 = t + 16
4t = 32
t = 8 books
s = 5t = 40 books
((Check: 40 - 16 = 24 = 8 + 16 ✔ ))

Answer:
ST = 8 m
SU = 7 m
m∠Q = 75°
m∠S = 59°
m∠R = 46°
m∠U = 46°
Step-by-step explanation:
The given parameter are;
ΔPQR is congruent to ΔSTU
In ΔPQR, m∠P = 59°, PR = 8 m, PQ = 7 m
In ΔSTU, m∠T = 75°
By Side-Angle-Side rule of congruence, and given that m∠P ≠ m∠T, we can have;
m∠S ≅ m∠P, by Congruent Parts of Congruent Triangles are Congruent, CPCTC
ST ≅ PR, SU ≅ PQ, m∠Q ≅ m∠T, m∠U ≅ m∠R
Therefore;
ST = PR = 8 m
ST = 8 m
SU = PQ = 7 m
SU = 7 m
m∠Q = m∠T = 75°
m∠Q = 75°
m∠S = m∠P = 59°
m∠S = 59°
m∠U = m∠R = 180 - (75° + 59°) = 46°
m∠R = 46°
m∠U = 46°.

Answer:
A. AG = 2 × GD
F. GE = (1/2) × BG
Step-by-step explanation:
The given point G on triangle ΔABC, which is the point of intersection of the medians of the triangle, is the centroid of the triangle
The centroid divides each median line in the ratio 2:1, therefore, we have;
The length of AG = 2 × GD, CG = 2 × GF, and BG = 2 × GE
∴ GE = (1/2) × BG
Therefore, the correct options are;
A. AG = 2 × GD, and F. GE = (1/2) × BG

The diagonal is the hypotenuese of a Right Triangle, so use the Pythagorean Theorom
a^2 + b^2 = c^2
Since it is a square a = b
so a^2 + a^2 = 50^2
2a^2 = 2500
a^2 =1250
a = 35.355 cm = lenght of a side

A submarine cruises underwater at 20 km/h and on
the surface at 30 km/h. The submarine travels a.
distance of 650 km in 25 h. A linear system was
created and graphed
Answers
Answer:
System of equations:
20x + 30y = 650
x + y = 25
Time underwater = 10 hours
Time at the surface = 15 hours
Step-by-step explanation:
Let x = time underwater at 20 km/h.
Let y = time on the surface at 30 km/h.
speed = distance/time
distance = speed * time
distance underwater: 20x
distance on the surface: 30y
total distance: 650
20x + 30y = 650
total time: x + y
total time: 25
x + y = 25
20x + 30y = 650
x + y = 25
20x + 30y = 650
-20x - 20y = -500
--------------------------------
10y = 150
y = 15
x + y = 25
x + 15 = 25
x = 10
