Answer:
The answer is 14
Step-by-step explanation:
Evaluate 13 + 6/ y when y = 6
We substitute 6 for y in the above expression
= 13 + 6/6
= 13 + 1
= 14
The answer to the the above question is 14
Answer:
∠Q = 75 °
Step-by-step explanation:
Since PR = PQ then Δ PQR is isosceles and the base angles are congruent, that is
∠R = ∠Q = 2x + 15
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
2x + 15 + 2x + 15 + x = 180, that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
Hence
∠Q = 2x + 15 = (2 × 30) + 15 = 60 + 15 = 75°
Answer:
First, we need to know the formula when a scale factor appears:
New coordinate = (scale factor)*(old coordinate)
So using this formula we have:
1) c' = (-2,1)*2/3
c' = (-4/3,2/3)
2) r = (-5,2)*2/3
r = (-10/3,4/3)
3) a = (-6,7)*2/3
a = (-4,14/3)
4) f = (-3,9)*2/3
f = (-2,6)
5) t = (-1,6)*2/3
t = (-2/3,4)
