Slope-intercept form is:

Given line in standard form:

Convert this to slope-intercept form:

Answer:

[tex]\boxed{y=\dfrac{3}{4}x-\dfrac{3}{4}}[/tex]

[tex]\implies \textsf{Slope}=\dfrac{3}{4}[/tex]

[tex]\implies \textsf{$y$-intercept}=-\dfrac{3}{4}[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

Given equation:

[tex]-3x+4y+3=0[/tex]

To write the given equation in slope-intercept form, rearrange the equation to isolate y.

Add 3x to both sides of the equation:

[tex]\implies -3x+4y+3+3x=0+3x[/tex]

[tex]\implies 4y+3=3x[/tex]

Subtract 3 from both sides of the equation:

[tex]\implies 4y+3-3=3x-3[/tex]

[tex]\implies 4y=3x-3[/tex]

Divide both sides of the equation by 4:

[tex]\implies \dfrac{4y}{4}=\dfrac{3x-3}{4}[/tex]

[tex]\implies y=\dfrac{3}{4}x-\dfrac{3}{4}[/tex]

Compare the rearranged equation with the slope-intercept formula:

[tex]\implies \textsf{Slope}=\dfrac{3}{4}[/tex]

[tex]\implies \textsf{$y$-intercept}=-\dfrac{3}{4}[/tex]

Binary Tree Data Structure: What is it?

A Binary Tree is a Tree data structure with two children or less. We typically refer to them as the left and right child since each element in a binary tree can only have two children.

Representation of a Binary Tree

A pointer to the topmost node of a binary tree serves as its representation. The root's value is NULL if the tree is empty.

The following components are found in a binary tree node:

The true proportion of the similar triangles is [tex]\frac{AC}{AE} = \frac{BC}{BD}[/tex]

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

In other words, similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other.

Therefore,

ΔACE is similar to ΔBCD

Hence,

[tex]\frac{AC}{BC}=\frac{AE}{BD}=\frac{CE}{CD}[/tex]

Therefore, the proportion that is true for the ΔACE and ΔBCD is [tex]\frac{AC}{AE} = \frac{BC}{BD}[/tex]

The proof of Δ SUE is not an isosceles triangle. is shown below.

If there are two points A(a, b) and B( c, d) then the distance between these two points are

AB= √( c-a )² + ( d-b )²

Given:

S(-2, -4), U(2, -1) and E(8, -9)

Using Distance formula

SU= √( 2 -(-2))² + ( -1-(-4))²

SU = √4²+ 3²

SU = √16+9

SU =5

and, UE = √( 8 -(2))² + ( -9-(-1))²

UE = √6²+ 8²

UE = √36+64

UE =10

and, ES= ( 8 +2 ))² + ( -9+4)²

ES = √10²+ 5²

ES = √100+25

ES = 5√5

As, none of the two sides are equal.

Answer:

No real zeros.

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Discriminant of the Quadratic Formula}\\\\$b^2-4ac$ \quad when $ax^2+bx+c=0$\\\\When $b^2-4ac > 0 \implies$ two real zeros.\\When $b^2-4ac=0 \implies$ one real zero.\\When $b^2-4ac < 0 \implies$ no real zeros.\\\end{minipage}}[/tex]

The value of the discriminant shows how many zeros the function has.

Given quadratic function:

[tex]f(x)=5x^2+5x+21[/tex]

Therefore:

Substitute the values into the discriminant and solve:

[tex]\begin{aligned}\implies b^2-4ac&=(5)^2-4(5)(21)\\& = 25 - 20(21)\\&=25-420\\&=-395\end{aligned}[/tex]

Answer:

129 degrees.

Step-by-step explanation:

The Sum of all the interior angles of an a-sided polygon is always (n−2) × 180 degrees.

As this is a seven-sided polygon, the sum of its interior angles is (7−2) × 180 degrees = 5 × 180 degrees = 900 degrees.

Step 1: Find the sum of six of the angles is 130 degrees, 118 degrees, 135 degrees, 128 degrees, 126 degrees, and 134 = 771 degrees

Hence the seventh angle is x = 900 degrees − 771 degrees= 129 degrees.

y=-1/5x

Step by Step

y=mx+b

First find the slope

equation: y2-y1 divided by x2-x1

1-(-1)/-5-5

2/-10

simplified to -1/5

Now that we have the slope we need the y-int

using point slope form: y-y1=m(x-x1)

Let us use the point (5,-1)

y-(-1)=-1/5(x-5)

y+1=-1/5x+1

Subtract 1 to both sides

y=-1/5x

The tip is 18%

From the question, we have

food and beverages cost = $25.30

meals tax = 8%

Tax = (8/100)* 25.3 =  $2.02

After adding a tip, the total lunch cost was $32.24.

Tip = $32.24. -  $27.32  = $4.92

% of Tip  = (4.92 /  27.32) * 100 =  18 %

The probability that at least one number is odd and the sum of the two numbers is even is 1/4

The probability that exactly one number is 6 and the product of the two numbers is at most 15 is 1/9

The easiest way to figure out probability problems with small data sets is to write out your entire sample space and then divide by the total:

Sample size = 6 * 6 = 36

S = {[1,1],[1,2],[1,3],[1,4],[1,5],[1,6],[2,1],[2,2],[2,3],[2,4],[2,5],[2,6],[3,1],[3,2],[3,3],[3,4],[3,5],[3,6],[4,1],[4,2],[4,3],[4,4],[4,5],[4,6],[5,1],[5,2],[5,3],[5,4],[5,5],[5,6],[6,1],[6,2],[6,3],[6,4],[6,5],[6,6]}

The only way to make a number combination that's even while 1 die is odd is to have 2 odd numbers.

{[1,1],[1,3],[1,5],[3,1],[3,3],[3,5],[5,1],[5,3],[5,5]}

This gives us 9 results.

The probability of this happening is 9/36 = 1/4 = 0.25

Now if we have to get a 6 with the product being at most 15 we know that the biggest number that 6 can be multiplied by is 2 which gives us 12.

We are left with 4 options:

{[1,6],[2,6],[6,1],[6,2]}

The probability of this happening is 4/36 = 1/9 = 0.1111...
