Rewrite
(7m-3)^2 as (7m-3) (7m-3) (7m-3) (7m-3)
Expand using foil method
7m(7m)+7m. -3 -3 (7m) -3. -3
Simplify 49m^2-42m+9
Use the form ax^2+bx=c to find the values of a,b,and c
a=49, b=-42, c=9
Consider the vertex form of a parabola
a (x+d)^2 +e
Find d
d=-3/7
To answer this, you will write and equation in terms of the number of adult tickets sold and then solve for a, the number of adult tickets.
$5a + $3.50s = $2517.50
$5a + $3.50(a + 100) = $2517.50
5a + 3.50a + 350 = 2517.50
8.50a -350 -350
<u>8.5a</u> = <u>2167.50</u>
8.5 8.5
a = 255
The number of adult tickets sold was 255, and the number of student tickets sold was 355 (255 +100).
Answer:
X=2
Step-by-step explanation:
6(x-2)+4=-2(x-4)
Distribution 6 the the parentheses
6x-12+4=-2(x-4)
Distribute -2
6x-12+4=-2x+8
Calculate the sum
-12+4=8
Move like terms
6x+2x=8x
constant change sign
-8 to +8
6x+2x=8+8
8x=16
Divide by 8 on both side
X=2
