Answer:

See Graph

Step-by-step explanation:

Find the Solution for

1x2+3x−4=0

using the Quadratic Formula where

a = 1, b = 3, and c = -4

x=−b±sqrtb^2−4ac/2a

x=−3±sqrt3^2−4(1)(−4/2(1)

x=−3±sqrt9−−16/2

x=−3±sqrt25/2

Simplify the Radical:

x=−3±sqrt5/2

We get x=22x=−82

which becomes

x=1

x=−4

Here is the graph:

S - 10,000 = 3,753<br><br>A. s = 13,573<br><br>B. s = 13,753<br><br>C. s = 10,375
Lesechka [4]

Answer:

B. s = 13753

Step-by-step explanation:

s - 10000 = 3753

To find value of s, add both sides by 10000

s - 10000 = 3753

   +10000    +10000

s = 13753

Answer:

Best Buy 30% of 379.99=113.99

379.99-113.99=$266.00

Costco 15% 409.99=61.50

409.99-61.50=348.49

Target 25% of 399.99=99.99

399.99-99.99=300

Best Buy has the best offer.
