Answer:

x= -1/2 = -0.500

x=4

Step-by-step explanation:

2x^2-7x-4=0

2x^2-8x+1x-4=0

2x(x-4)+1(x-4)=0

(2x+1)(x-4)=0

2x+1=0...2x= -1.. x= -1/2 x-4=0 .. x=4

checking the solution

2(-1/2)^2-7(-1/2)=4..... 4=4

2(4)^2-7(4)=4....... 4=4

You are trying to forecast coffee sales for the holiday season. You sold 1,500 cups of coffee during the holidays last year, but

Airida [17]

Hello there!

You expect to sell 100% - 20% = 80% of many coffee sales.

0.80 * 1500 = 1200

Your answer is 1200 cups of coffee.

Hope I helped!

Let me know if you need anything else!

X+8=-15 help again sorryyy

suter [353]

X by its self is always 1x

1x+8=-15 you have to get rid of 8 by subtracting on both sides

1x=-23 now get rid of 1 by dividing on both sides

x=-23
