Answer: x= -9,8

Step-by-step explanation:

x=?

y=0

y=x^2+x-72

0=x^2+x-72

0=(x+9)(x-8)

x+9=0 x-8=0

-9 -9 +8 +8

x= -9 x=8

How you do this? I've been trying but I keep getting it wrong

Answer:

you plug in (y) with the top equation

Step-by-step explanation:

step 1: 2x+1/2x-1=-6

step 2: 2.5x-1=-6

step 3: 2.5x-1=-6

+1. +1

step 4: 2.5x= -5. Divide both sides by 2.5

-5/2.5 = -2

step 5: plug in your (x) to find (y)

y= 1/2(-2)-1

step 6: 1/2(-2) = -1

y=( -1)-1

y=-2

step 7: (x,y)= (-2,-2)

step 8: graph your coordinate

I hope that this helped you!

I don't know if it's right but this is what I did. the rounding might be a little different.

$(1 + 3.5) \div 2 \times x = 8.1$
$4.5 \div 2 = 2.3$
$2.3x = 8.1$
$8.1 \div 2.3 = 3.5$
x=3.5 cm.
