Mathematics
1 answer:
liraira [26]2 years ago
3 0

Answer:

\displaystyle y = -3x + 9

Step-by-step explanation:

First, find the <em>rate of change</em> of the line:

\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{-1 + 2} = m \hookrightarrow \frac{-3}{1} = m \\ \\ \boxed{-3 = m}

_______________________________________________

Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:

\displaystyle 3 = -3[2] + b \hookrightarrow 3 = -6 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}} \\ \\ OR \\ \\ 6 = -3[1] + b \hookrightarrow 6 = -3 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}}

I am joyous to assist you at any time.

A box contains one yellow, two red, and three green balls. Two balls are randomly chosen without replacement. Define the followi
Vinil7 [7]

Answer:

Step-by-step explanation:

Given that a  box contains one yellow, two red, and three green balls.

Two balls are randomly chosen without replacement.

A) one ball is yellow:

This means one is yellow and other can be any other colour

i.e. drawing one yellow and one from 5 remaining.

This can be as (y,r) (y,g) (r,y) or (g,y)

where y for yellow, r for red and g for green.

B) { At least one ball is red }

This means the two balls should not be different from red.

The favorable outcomes are  two red, (one red, one yellow) (one green, one red). But should not be (green,yellow)

C) :{ Both balls are green }

Here the balls drawn should be only green, green and not any other combination.

D) { Both balls are of the same col

Since yellow is one, there cannot be two yellows

Hence only possibilities are (red, red) or (green, green)

(4x + 3)(4x - 3)<br> Help pls
tekilochka [14]

Answer:

16x^2-9

Step-by-step explanation:

\left(4x+3\right)\left(4x-3\right)

We´ll <u>Apply Difference Two Squares Formula:</u>

  • \left(a+b\right)\left(a-b\right)=a^2-b^2

\longmapsto \left(4x+3\right)\left(4x-3\right)

\longmapsto \left(4x\right)^2-3^2

<u>Apply exponent rule</u>:

  • \left(a\times \:b\right)^n=a^nb^n

\longmapsto 4^2x^2-3^2

\longmapsto 16x^2-9

The battery standby duration (in hours) of a new model of cell phone is known to be normally distributed. Ten pieces of such new
Stells [14]

x = number of hours

want to find probability (P) x >= 13

x is N(14,1) transform to N(0,1) using z = (x - mean) / standard deviation so can look up probability using standard normal probability table.

P(x >= 13) = P( z > (13 - 14)/1) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413

To convert that to percentage, multiply 100, to get 84.13%

This can be thought of as -8a/1 times 1/9. (1/9 is the reciprocal of 9, so were just pulling the fraction apart)
