Answer:
(-2, 5)
Step-by-step explanation:
we subtract 6x+3y=3 by 2x+3y=11 to get 4x=-8.
we divide both sides by 4 to get x. x=-2
We subsitute -2 for the second equation to get:
2(-2)+3y=11
=-4+3y=11
=3y=15
y=5
Put an open circle pointing to the left on -1
Student Tickets - x-64
Adult Tickets - x
x+x-64=386
2x=450
x=225
225 adult tickets were sold,
161 student tickets were sold.
Hope that helps!
Answer:
Step-by-step explanation:
"For a polynomial, no matter how many terms it has, always check for a greatest common factor (GCF) first. Literally, the greatest common factor is the biggest expression that will go into all of the terms. Using the GCF is like doing the distributive property backward.
If the equation is a trinomial — it has three terms — you can use the FOIL method for multiplying binomials backward.
If it’s a binomial, look for difference of squares, difference of cubes, or sum of cubes.
Finally, after the polynomial is fully factored, you can use the zero product property to solve the equation."
