y = x^3 + 5x + 1
y = x

When they are equal
x^3 + 5x + 1 = x
x^3 + 4x + 1 = 0
x(x^2 + 4) = -1

-0.25((-0.25)^2 + 4) = -0.25(0.0625 + 4) = -1.02

Therefore, the equation is equal at approximately x = -0.25

Hope this helped:) Have a good day!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

If the average volume flow of blood through the aorta is 8.5 × 10-5 m 3/s and the cross-sectional area of the aorta is 3.0 × 10

valkas [14]

The average speed of blood in the aorta is 0.2833 m/s

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

From the question, to calculate the average speed:

Average speed = Volume rate / cross sectional area

Average speed = 8.5 * 10⁻⁵ / (3 * 10⁻⁴) = 0.2833 m/s

The average speed of blood in the aorta is 0.2833 m/s

Given that GJ=70.2, JH=26, and GK=70.2, find the measure of JK

pychu [463]

Answer:

Step-by-step explanation:

The two sides (GJ and GK) are congruent, and the angle of ∠GHJ is 90°.

It means JH ≅ HK.

JH = 26 so you multiply 2.

26 x 2 = 52

JK = 52

Correct answer will get brainliest

Sophie [7]

Answer:

4.) Choice B

5.) Choice A

Step-by-step explanation:

Question 4:

First you have to solve for y to get slope intercept form.

$2x-5y=6\\5y=-2x+6\\y=-\frac{2}{5}x+\frac{6}{5}$

The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.

Question 5:

For this one I we will use this formula $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

I will choose the easy pairs to plug it in $(-12,-2) (20,6)$

$\frac{6--2}{20--12}\\\\\\\frac{8}{32}=\frac{1}{4}$

The slope is a fraction again but you can convert it and that'll be Choice A.

What is slope of the line -3y=8x -5?

professor190 [17]

When finding the slope of a line you need to get it into the form y=mx+b, m being your slope. So if you divide your entire problem by -3 to isolate your y, you get y=-8/3x+5/3. This means that -8/3 will be your slope.
