Since angles A and C are equivalent, then angles B and D must also be equivalent. So if
angle B = angle D then...
7x + 15 = 8x
Now we just solve for x
7x + 15 = 8x
15 = 8x - 7x
15 = x
We Can check to see if it is correct by substituting 15 in for x in the equation..
7x + 15 = 8x
7 (15)+15 = 8 (15)
105 +15 = 120
120 = 120
It checks! angles B and D = 120 degrees
Answer:
the funtion does not satisfies the hypothese f(a)=f(b), just because when evaluate f(0) = 1 and when evaluate f(2) = 11,

{7c+9a=4475
2c=286
c=143
a=529-143=386
There are 143 children and 386 adults used the public swimming pool.
Answer:
the signs
Step-by-step explanation:
the greater than or less than symbol change the whole meaning of the equation. the difference between less than or greater than affect the equation read and the value.
