Answer:
Step-by-step explanation:
5x+y-7=0 isolate y
y=-5x+7 (m=-5,b=7)
9x+7y-14=0
7y=14-9x ( divide both sides by 7)
y=-9x/7 +14/7
y=-9/7 + 2 (m=-9/7, b=2)
x+y=1000
4x+3y=3600 ( multiply the first equation by 3 to eliminate y)
3x+3y=3000
4x+3y=3600 ( subtract the two equations)
3x+3y-(4x+3y)=3000-3600
3x+3y-4x-3y=-600
-x=-600
x=600 ( substitute x in the equation)
x+y=1000
600+y=1000
y=1000-600=400
check : x+y=1000 , (600+400)=1000
check : 4x+3y=3600 = (4(600)+3(400))=2400+1200=3600
how many tickets are sold :
adults x=600/4=150
kids (y)=400/3=133 tickets+1 dollars left
unless( x represent kids then x=200, y represent adult = 100)
Answer:
B. segment DE bisects segment AC
Step-by-step explanation:
BD splits AC directly in half as shown by the dashes. AE is equal to EC. The definition of bisect is to divide into two equal parts.
Use distributive property
6x + 12 = -8x + 2 + 6x
Now simply
6x + 12 = -2x + 2
8x + 12 = 2
8x = -10, x = -10/8. Simplify: x = -5/4
Solution: x = -5/4
