When graphing the following equation which one will give you a straight line?

Please help I will BRAINLIST if right

katen-ka-za [31]

Answer:

25 $x^{4}$ y²

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length )

A = (5x²y)²

= 5 × 5 × x² × x² × y × y

= 25 $x^{4}$ y²

The slope of the line below is 0.5. Write the equation of the line in point-slope form, using the coordinates of the labeled poi

Arturiano [62]

The complete question is
The slope of the line below is 0.5 Write the equation of the line in point-slope form, using the coordinates of the labeled point. <span>It's on a number line which is (3,-3) Do not use parenthesis on the y side.

we know that

</span>Point slope form is
<span>y - y₁ = m(x - x₁) </span>

<span>Where m= slope and (x₁, y₁) is a point on the line
</span><span>Plug in m = 0.5 and point (3, -3)
</span><span>y-(-3)=0.5*(x-3)------> y+3=0.5*(x-3)

the answer is
</span> y+3=0.5*(x-3)<span>

</span>

Which equation represents a line that passes through (–9, –3) and has a slope of –6?

Dahasolnce [82]

<h2>Hello!</h2>

The answer is:

The last equation,

$y+3=-6(x+9)$

To find which of the given equations represents a line that passes through the point (-9,-3) and has a slope of -6, we need to find an equation that can be satisfied by evaluating the given point.

We can see that the only equation that can be satisfied evaluating the point (-9,-3) is the last equation:

$y+3=-6(x+9)$

Evaluating the point, we have:

$-3+3=-6*(-9+9)$

$0=-6*(0)$

$0=0$

We can see that the equation is satisfied!

Also, we can see that evaluating the point into the other equations, they will not be satisfied.

Let's prove that:

Evaluating:

First equation:

$y-9=-6(x-3)\\-3-9=-6*(-9-3)\\-12=-6*(-12)=72$

The equation is not satisfied.

Second equation:

$y+9=-6(x+3)\\-3+9=-6*(-9+3)\\6=-6*(-6)=36$

The equation is not satisfied.

Third equation:

$y-3=-6(x-9)$

$-3-3=-6(-9-9)$

$-6=-6(-18)=108$

The equation is not satisfied.

Hence, the correct option is the last option, the equation that represents a line that passes through (–9, –3) and has a slope of –6 is the last equation:

$y+3=-6(x+9)$

Have a nice day!

Arsenic is a compound that occurs naturally in very low concentrations. Arsenic blood concentrations in healthy adults are Norma

DENIUS [597]

Answer:

0.7325 to 5.6675 ug/dl

Step-by-step explanation:

The middle 90% will be 45% above the mean and 45% below the mean. This means

0.5-0.45 = 0.05 and

0.5+0.45 = 0.95

We use a z table. Look in the cells; find the values as close to 0.05 and 0.95 as we can get.

For 0.05, we have 0.0505 and 0.0495; since these are equidistant from 0.05, we use the value between them. 0.0505 is z=-1.64 and 0.0495 is z=1.65; this gives us z=-1.645.

For 0.95, we have 0.9495 and 0.9505; since these are equidistant from 0.95, we use the value between them. 0.9495 is z = 1.64 and 0.9505 is z=1.65; this gives us z = 1.645.

Now we use our z score formula,

$z=\frac{X-\mu}{\sigma}$
