Answer:
4,000 and 40
Step-by-step explanation:
Answer:
y=-5/2x+4
Step-by-step explanation:
5x+2y=8
2y=8-5x
2y=-5x+8
y=-5/2x+8/2
y=-5/2x+4
124 tickets sold at $9.20 = $1140.80
124÷4 =31
31 tickets sold at $5.30 = $164.30
$1140.80+$164.30=$1305.10
so so if you take the 124 tickets and divide it by 4 you get 31. The answer is 31 rickets were sold that day.
If you evaluate your polynomial at x= - 3, the polynomial = 0. So, that means ( x + 3 ) is a factor. Either using long division, or synthetic division, you'll find out that 2x^3 - 9x^2 + 3x + 4 remains. Then if you try x = 4 on that remaining polynomial, it will = 0. Use long division or synthetic division to find out that 2x^2 - x - 1 is left over. That trinomial factors into ( 2x + 1 ) ( x - 1 ).
factored form is ( x+3 )( x - 4 )( 2x + 1 )( x - 1 )
4 x 1/5 is 4/5 so it is not that one. 1/5+1/5+1/5+1/5 equals 4/5 so it is not that one. 2 x 2/5 is 4/5 so it is not that one.
2+2/5 is 12/5 so this expression does not equal 4/5
