Create formulas!
x=number of adult tickets
y=number of student tickets
x+y=644 <em>total sold</em>
56+y=x <em>student was 56 less than adult</em>
Perform substitution
(56+y)+y=644
56+2y=644
2y=588
y=294
Substitute y into the formula we created
x+294=644
x=350
350 adult tickets were sold.
Answer:
C the slope of a line is positive
Step-by-step explanation:
Hypothesis: The phrase following the "if" part of a conditional statement. So the answer would be c- The slope of a line is positive.
Answer:
a = -1, b = -2.5
Step-by-step explanation:
Rule for the dilation of a vector 
by a scale factor of k is,
(x, y) → (kx, ky)
BY using this rule for a vector 
by a scale factor of 2.5
→ 
Followed by the rotation by 90° Or 
radians,
Rule for rotation of a vector by 90° is,
(x, y) → (-y, x)
By this rule vector will become,
→ 
If we represent this vector by 
,
Then a = -1 and b = -2.5 will be the answer.
Add 11 on both sides to get
3=z
