Answer: The points are, the top left one, (21,3) and the one on the bottom is (6, 12)

Step-by-step explanation: For the slope, we label one of the points, with y or x. For example, (21, 3) we would label 21 either y1 or x1. Say we put y2, then 3 would be x2. Moving on, (6,12) this time we could label 6 as either y1 or x1. Same thing, but this time we are going to label 6 as y1 and 12 x1. Again, it’s DOES NOT matter what you label them as.

Now to solve it, remember y numbers always go on top! M which is slope. M = y2 - y 1 / x2 - x 1 or with the numbers M = 21 - 6 / 12 - 3 = 15/9 simplified = 5/3

Answer:

$\huge\boxed{\tt{x = -5 , y = 2}}$

Step-by-step explanation:

x = y - 7 ---------------------(1)

-y - 2x = 8 --------------------(2)

Put Equation (1) into (2)

- y - 2 ( y-7 ) = 8

-y - 2y + 14 = 8

-3y = 8 - 14

-3y = -6

Divide -3 to both sides

y = -6 / -3

y = 2

Put y = 2 in (1)

x = 2 - 7

x = -5

So,

x = -5 , y = 2

$\rule[225]{225}{2}$

Hope this helped!

What is the Integral of 10^ln x dx?

Serjik [45]

$10^{\ln x}=e^{\ln 10^{\ln x}}=e^{\ln x\cdot\ln 10}=(e^{\ln x})^{\ln10}=x^{\ln10}$

So we have

$\displaystyle\int10^{\ln x}\,\mathrm dx=\int x^{\ln10}\,\mathrm dx}=\dfrac{x^{1+\ln10}}{1+\ln10}+C$

which, as the above manipulation showed, is equivalent to

$\dfrac{x10^{\ln x}}{1+\ln10}+C$

A box contains 3 blue marbles, 5 red marbles, and 4 white marbles. If one marble is drawn at random, find P(not red Inot white).

xz_007 [3.2K]

Answer:

Step-by-step explanation:

p(b)=3/12 = 0.25

p(r)=5/12 = 0.42

p(w)=4/12 = 0.33

p(¬r) = 1-0.42 = 0.58

p(¬w)= 1-p(w) = 0.67

P(not red Inot white)= 0.58/0.67=0.87
