Given the equation:

Alisiya [41]

Answer:

x = 1 and x = $\frac{-4}{5}$

Step-by-step explanation:

In this equation, a=5, b=-1, c=-4.

Plug these into the quadratic formula:

x = $\frac{1+\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}$ and x = $\frac{1-\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}$

Now, simplify the equations:

x = $\frac{1+\sqrt{81} }{10}$ = $\frac{1+9}{10}$ = $\frac{10}{10}$ = 1

and

x = $\frac{1-\sqrt{81} }{10}$ = $\frac{1-9}{10}$ = $\frac{-8}{10}$ = $\frac{-4}{5}$

HELP QUICK LOL THANKS !!!

Answer:

0.6

Step-by-step explanation:

The x increases by 5, while y increases by 3

Lets use the method, which is $\frac{rise}{run}$ .

Keep in mind that x goes horizontally along the axis, while y goes vertically on the axis.

So plug the numbers in.

$\frac{3}{5} =$ 0.6

Hence, the constant proportionality is 0.6.

AleksAgata [21]

Answer:

Circle graph

Step-by-step explanation:

The key words are "as a whole."

A Venn Diagram only compares and contrasts two things.

A line graph shows the rise and/or drops of things.

Idk what a histogram is lol
