1 answer:

$\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{5})\qquad 
(\stackrel{x_2}{3}~,~\stackrel{y_2}{25})
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{25-5}{3-(-2)}\implies \cfrac{25-5}{3+2}
\\\\\\
\cfrac{20}{5}\implies 4
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-5=4[x-(-2)]
\\\\\\
y-5=4(x+2)\implies y-5=4x+8\implies y=4x+13$

A six-sided number cube is rolled 350 times and the results are recorded as follows: 58 ones, 63 twos, 52 threes, 61 fours, 60 f

garik1379 [7]

Answer:

The Answer is A. 83%

Step-by-step explanation:

The Probability a certain event= 1- Probability of that certain event not to happen.

According to this, it is true that:

Probability (not rolling 5)=1- P(rolling 5) = 1=60/350= 1-6/35 =35-6/35=29/35=0.83

1. ∠1 ≅ ∠3 1. given

∠1 and ∠6 are supplementary angles

∠3, ∠4, and ∠5 are supplementary angles

2. m∠1 = m∠3 2. definition of congruency

3. m∠1 + m∠6 = 180° 3. definition of supplementary angles

m∠3 + m∠4 + m∠5 = 180°

4. m∠3 + m∠4 + m∠5 = m∠1 + m∠6 4. transitive property

5. m∠3 + m∠4 + m∠5 = m∠3 + m∠6 5. substitution property

6. m∠4 + m∠5 = m∠6 6. subtraction property of equality

Which graph shows the solution of the inequality −|x − 2| + 9 > 6?

mariarad [96]

answer is -1 < x < 5

-|x - 2|+ 9 > 6

Rearrange the terms

-|x - 2| > 6 - 9

-|x - 2| > - 3

then divide both sides of the inequality by the co- efficient of variable

|x - 2| < 3

convert the absolute inequality to standard inequality

-3 <x - 2 < 3

separate compound inequalities into system of inequality

{x - 2}> -3

{x - 2 < 3}

Rearrange variable to the left side of the equation

x > -3 + 2

calculate the sum or difference

x > -1

x -2 < 3

Rearrange variable to the left side of the equation

x < 3 + 2

calculate the sum or difference

x < 5

x > -1 and x < 5

Find intersection

-1 < x < 5

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =. Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
