What are the coordinates of the x-intercept(s) of the graph of y=(x-6)(x+5)

MissTica

Answer:

(-5 , 0) and (6 , 0)

Step-by-step explanation:

In order to get the coordinates of the x-intercept(s) of the graph of y=(x-6)(x+5)

we need to solve for x the equation (x-6)(x+5) = 0

(x-6)(x+5) = 0

⇌

x - 6 = 0 or x + 5 = 0

⇌

x = 6 or x = -5

therefore

the coordinates are :

(-5 , 0) and (6 , 0)

Help ASAP solve: -3/4n = -6

anyanavicka [17]

Answer:

$\huge\boxed{n=8}$

Step-by-step explanation:

$-\dfrac{3}{4}n=-6\qquad|\text{multiply both sides by (-4)}\\\\(-4\!\!\!\!\diagup)\left(-\dfrac{3}{4\!\!\!\!\diagup}n\right)=(-4)(-6)\\\\3n=24\qquad|\text{divide both sides by 3}\\\\\dfrac{3\!\!\!\!\diagup n}{3\!\!\!\!\diagup}=\dfrac{24\!\!\!\!\!\diagup}{3\!\!\!\!\diagup}\\\\n=8$

!!!!!!!!!I AM CRYINGGGG!!!!!! PLZZZZ

andrey2020 [161]

Answer:

-x^2-2x-3

Step-by-step explanation:

Question 1: Just substitute in the values of f(x) and g(x) and simplify!

f(x) - g(x) = 4x^2-5x+3-(5x^2-3x+6)
f(x)-g(x) = 4x^2-5x+3-5x^2+3x-6
f(x)-g(x) = -x^2-2x-3

Tell me if this helps, and if you still need number 2 or if you can do it by yourself! (Hint: substituting also plays a role in question number 2.)

Hope this helps!!

College students average 8.6 hours of sleep per night with a standard deviation of 35 minutes. If the amount of sleep is normall

Soloha48 [4]

Answer:

4.27%

Step-by-step explanation:

We have been given that college students average 8.6 hours of sleep per night with a standard deviation of 35 minutes. We are asked to find the probability of college students that sleep for more than 9.6 hours.

We will use z-score formula to solve our given problem.

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