Luda [366]2 years ago
4 0

Answer:

x=-0.544727

x=2.294727

Step-by-step explanation:

Given quadratic equation to solve:

  • -4x²+7x+5=0

To solve, use the quadratic formula

x= -b ±  b² - 4ac / 2a

Substitute your values for a, b, & c and solve

x= -7 ± 7² - 4·(-4)·5 / 2·(-4)

x= -7 ± 49 - -80/-8

x= -7 ± 129/-8

Then, reduce the problem

x= -7/-8 ± 129/-8

x=-0.544727

x=2.294727

galina1969 [7]

Answer:

Y < ac      (Y>0)

Step-by-step explanation:

Let Y represent the number of cups of juice Helena has

Let c represent the number of cups of juice Lila has

Let a represent the time number of cups of juice as Lila. Helena has of a cup of juice less than Miren

Because Helena has of a cup of juice less than Miren so we have: Y < ac when ac is the number of cups that Miren  has, so finally, we have 3 variables in this expresion.

Hope it will find you well.

Triss [41]
Hi there!

If you draw a line of best fit on the graph, you'll see that points K and F lie way outside of the line. Therefore, points K and F are outliers.

Hope this helps!! :)
