4s+7a=861
s+a=168
This can be solved using either elimination or substitution. I am going to use substitution.
Solve s+a=168 for s
s=168-a
Replace 168-a for s in 4s+7a=861
4(168-a)+7a=861
672-4a+7a=861
Solve for a
672+3a=861
3a=189
a=63
Substitute 63 for a in s=168-a
s=168-63=105
So, s=105 student tickets and a=63 adult tickets
Answer:
Step-by-step explanation:
A.) As the number of hours spent on homework increases, the test scores received also most likely will increase.
B.) If someone does 2 hours of homework, you just sub in 2 for x, so you should get the equation y=8(2)+40, or a score of 56.
C.) The 40 is the y intercept, which means that the student is guaranteed to get at least a 40 on a test even if they study for 0 hours.
Hope this helps :)
Answer:
see explanation
Step-by-step explanation:
The equation of a circle in general form is
x² + y² + 2gx + 2fy + c = 0
with centre = (- g, - f) and radius = 
Given
2x² + 2y² + 6x - 8y + 12 = 0 ← divide through by 2
x² + y² + 3x - 4y + 6 = 0 ← in general form
Compare like terms
2g = 3 ⇒ g = 
2f = - 4 ⇒ f = - 2 and c = 6, thus
centre = ( - , 2 ) and
radius = 
= 
= 
= 
Answer:
The absolute value of -10 is -10
Step-by-step explanation:
Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative.
...
Absolute Value (For example)
|6| = 6 means the absolute value of 6 is 6.
