What is the Standard Form of the line with x-intercept of 6 and y-intercept of 5?
kolbaska11 [484]

keeping in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

\bf \stackrel{\textit{x-intercept}}{(\stackrel{x_1}{6}~,~\stackrel{y_1}{0})}\qquad \stackrel{\textit{y-intercept}}{(\stackrel{x_2}{0}~,~\stackrel{y_2}{5})} ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{5}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{0}-\underset{x_1}{6}}}\implies -\cfrac{5}{6}

\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{-\cfrac{5}{6}}(x-\stackrel{x_1}{6}) \\\\\\ \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{6}}{6(y-0)=6\left(-\cfrac{5}{6}(x-6) \right)}\implies 6y=-5(x-6) \\\\\\ 6y=-5x+30 \implies 5x+6y=30

PLEASE HELP!! A fair coin is flipped 3 times. What is the probability of the coin landing on heads 3 times? Why is that?
Leokris [45]

Answer:

If the coin is fair, then the odds of getting heads or tails should be equal, 12. Then 3 tosses of tails will have a chance of 12⋅12⋅12=18.

Find each product or quotient.
solniwko [45]

-38(-3) = 114

-72/(-12) = 6

-9 x 23 = -207

-150/5 = -30

564 / -4 = -141

<h3><u>Solution:</u></h3>

Given that, we have to find each product or quotient

<em><u>-38(-3)</u></em>

It is a product, so we have to find product value

-38(-3)=38 \times 3=114

<em><u>-72 / (-12)</u></em>

It is division, so we have to find the quotient

\frac{-72}{-12}=\frac{72}{12}=6

<em><u>-9 x 23</u></em>

It is a product, so we have to find product value

-9 \times 23=-207

<em><u>- 150 / 5</u></em>

It is division, so we have to find quotient

\frac{-150}{5}=-30

<em><u>564 / -4</u></em>

It is division, so we have to find the quotient

\frac{564}{-4}=-141

PLEASE HELPP Write the equation of the line fully simplified slope-intercept form.
Mkey [24]
The answer will be: Y = -2/5x - 4

Slope intercept form: y= Mx+b

You find the slope (M) using: rise/run formula
You find (b) by looking at the y-intercept
