Answer:
C
Step-by-step explanation:
Because the input(x) does not repeat more than once
The answer is: " y = -15x + 104 " .
_________________________________________
y = mx + b ;
m = -15
y = -15x + b
When x = 7 ; y = -1 ;
-1 = -15(7) + b
-1 = -105 + b ;
________________
Solve for "b"
_________________
-1 = -105 + b ; ↔ - 105 + b = -1 ;
↔ b − 105 = -1
________________________
Add "105" to each side of the equation:
________________________________
b − 105 + 105 = -1 + 105 ;
b = 104
_______________________________
y = mx + b ; → y = -15x + 104 .

Answer:
5.3 but the three is repeated
Step-by-step explanation:
Answer:
64 degrees
Step-by-step explanation:
Since the triangles are similar they have the same angle measures
∠P = ∠S ∠R =∠U ∠Q=∠T
We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U
In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula
subtract 116 from both sides
Therefore ∠Q is equal to 64 degrees
