Answer:
x = 0
y = 1
Step-by-step explanation:
I'm on a school laptop so the pic is blocked, i can not seeee.
Answer:
I believe that the missing value is 5, y=5
Step-by-step explanation:
1st since you can see in the ordered pair that 8 is in the x place that means 8 is the x value so what you can do is rewrite the equation to look like this: 5(8)-2y=30
2nd solve for y
5(8)-2y=30
40-2y=30
-40. -40 -subtract 40 on both side
-2y=-10
÷-2. ÷-2 -divide -2 on both sides
y=5
Since the hotdog is $2.99 with 7% tax increased by hotdog then
$2.99+0.07(2.99)
$2.99+$0.21
=$3.2
I don't think there is a way to answer your question.
Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) )
x = [-5 ± √(25 - (-40) ) ] / ( -4 )
x = [-5 ± √(65) ] / ( -4)
x = [-5 ± sqrt(65) ] / ( -4 )
x = 5/4 ± -sqrt(65)/4
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
