Answer:

250

Step-by-step explanation:

She spins the spinner 1 thousand times, there is only 1 blue tile so 25% of 100 would be 25 but since its 1000 just add a zero to 25 and you have 250

Y=3x\4 if y= -6 find the value of x<br>please answer this for me, it's graded​
sveticcg [70]

Answer:

x = -8

Step-by-step explanation:

y = 3x/4

Substitute the value of -6 into y.

-6 = 3x/4

Multiply both sides by 4.

-24 = 3x

Divide both sides by 3.

x = -8.

1) P=2w +2l
46=2w +14
32=2w
16= w or width

2) A=lw
A=7 x 12
A= 84

3) A= 12 x 21
A= 252

Show that the equation x^4/2021 − 2021x^2 − x − 3 = 0 has at least two real roots.
andreev551 [17]

The roots of an equation are simply the x-intercepts of the equation.

See below for the proof that \mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0} has at least two real roots

The equation is given as: \mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}

There are several ways to show that an equation has real roots, one of these ways is by using graphs.

See attachment for the graph of \mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}

Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)

From the attached graph, we can see that \mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0} crosses the x-axis at approximately <em>-2000 and 2000 </em>between the domain -2500 and 2500

This means that \mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0} has at least two real roots
