Answer:
pattern P: 8,13,23,43,83
pattern Q: 6,10,18,34,66
The tables that contain the first 5 elements of both patterns are:
Pattern P: 8, 13, 23, 43, 83Pattern Q: 6, 8, 12, 20, 36How to find the first 5 terms of each pattern?For pattern P we start at 8, and to get the next element we multiply by 2, and then subtract 3.
So the first 5 elements are:
[tex]a_1 = 8\\\\a_2 = 2*8 - 3 = 13\\\\a_3 = 2*13 - 3 = 23\\\\a_4 = 2*23 - 3 = 43\\\\a_5 = 2*43 - 3 = 83[/tex]
For pattern Q we start at 6, and then we subtract 2 and multiply by 2 to get the next element.
[tex]b_1 = 6\\\\b_2 = (6 - 2)*2 = 8\\\\b_3 = (8 - 2)*2 = 12\\\\b_4 = (12 - 2)*2 = 20\\\\b_5 = (20 - 2)*2 = 36\\\\[/tex]
Then the tables that contain the first 5 elements of both patterns are:

______ = ______, which simplifies to 2.
7 - 4 3
Therefore, 2 is the slope of this equation.
Answer:
Slope: 2
Step-by-step explanation:
Given points:
(4, 6)(7, 12)Slope formula: (y₂ - y₁)/(x₂ - x₁)
1. Substitue the coordinates of the points in the formula, which will determine the slope of the two points:
[Formula] Slope = (y₂ - y₁)/(x₂ - x₁)[Substitute] Slope = (12 - 6)/(7 - 4)2. Simplify the fraction. The quotient will be the slope of the line.
[Simplify] Slope = (6)/(3) = 2Thus, the slope of the line is 2.

Answer:
A = 28 cm²
Step-by-step explanation:
area of square = 4 × 4 = 16 cm²
area of trapezium = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the height and b₁ , b₂ the parallel bases
here h = 2 , b₁ = 8 , b₂ = 4
area of trapezium = [tex]\frac{1}{2}[/tex] × 2 × (8 + 4) = 1 × 12 = 12 cm²
area of the logo (A) = 16 + 12 = 28 cm²

Let's look at the information given:
base length ⇒ [tex]15\frac{1}{4}[/tex] in ⇒ [tex]\frac{61}{4}[/tex] (when converted into an improper fraction)height length ⇒ 18 inLet's solve:

Write the equation
for this line in
slope-intercept form.
y = ?/?x+ ?
Answer:
y = 2/3x - 1 (or y = 2/3x + -1 to fit the graphic)
Step-by-step explanation:
Slope intercept form is written as (y = mx + b) where m is slope and b is the y intercept.
First you need to find the slope, m. We'll use the two points (-3, -3) and (3, 1)
m = (y2 - y1) / (x2 - x1)
m = (1 - (-3)) / (3 - (-3))
m = 4/6
m = 2/3
Next we need the y intercept, b. On the graph we can see that is -1 but we can also find it substituting the known slope and one point on the line for our values to solve for b. We'll use (3, 1) as the point.
y = mx + b
1 = 2/3 * 3 + b
simplify 2/3 * 3
1 = 2 + b
subtract 2 from both sides
-1 = b
Now we have all the values we need to plug into our slope intercept equation (m = 2/3, b = -1)
y = mx + b
y = 2/3x - 1
[tex]\sf{y=\displaystyle\frac{2}{3} x-1[/tex]
Solution:We are given two points: (3, 1) and (-3, -3).We can use these points to find the slope of the line:m=[tex]\displaystyle\frac{y2-y1}{x2-x1}[/tex][tex]\displaystyle\frac{-3-1}{-3-3} =\frac{-4}{-6} =\frac{2}{3} \longleftarrow\sf{slope}[/tex]Now, we need to identify the line's y-intercept.The y-intercept is the point where the graph touches the y-axis.Since the graph touches the y-axis at (0, -1) the y-intercept is equivalent to (0, -1) or -1.Hope it helps.

a) (2x + 1)(3x - 4)
b) 546
Step-by-step explanation:
a)
We need to try to factor the polynomial.
6(-4) = -24
6x² - 8x + 3x - 4 = 2x(3x - 4) + 1(3x - 4) =
= (2x + 1)(3x - 4)
b)
6(10)² - 5(10) - 4 = 600 - 50 - 4 = 546
Answer:
(a) when x = 2: width = 2 units and length = 5 units
(b) 546 units²
Step-by-step explanation:
Given expression:
[tex]6x^2-5x-4[/tex]
Part (a)
To factor a quadratic in the form [tex]ax^2+bx+c[/tex]
Find 2 two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]
Two numbers that multiply to -24 and sum to -5: -8 and 3
Rewrite [tex]b[/tex] as the sum of these 2 numbers:
[tex]\implies 6x^2+3x-8x-4[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies 3x(2x+1)-4(2x+1)[/tex]
Factor out the common term [tex](2x+1)[/tex]:
[tex]\implies (3x-4)(2x+1)[/tex]
Therefore:
[tex]\implies x=\dfrac{4}{3}, \: x=-\dfrac{1}{2}[/tex]
As distance is positive, [tex]x > \dfrac{4}{3}[/tex]
Let [tex]x=2[/tex]
[tex]\implies (3(2)-4)(2(2)+1)[/tex]
[tex]\implies (2)(5)[/tex]
Therefore, possible dimensions of the rectangle are:
width = 2 units
length = 5 units
Part (b)
Substitute [tex]x=10[/tex] into the equation:

How to analyze second order polynomials graphically
Graphically speaking, second order polynomials are represented by parabolas. In this question we must interpret the graphs to find all the required information.
Question 1The solutions to the graph are those values of x such that the graph goes through the x-axis and the axis of symmetry is a line that goes through the vertex ot the parabola and is perpendicular to the width of the curve.
Thus, the solutions to the graph are x = 2 and x = 4 and the axis of symmetry is x = 3. [tex]\blacksquare[/tex]
Question 3The vertex is the extreme point of a parabola, which may be a minimum or a maximum, but never both. The vertex of the parabola is located at (x, y) = (-3, 5). [tex]\blacksquare[/tex]
Question 4A parabola cannot have both a minimum and maximum point because it is only bounded by its vertex. [tex]\blacksquare[/tex]
Question 5The domain of the function is defined by the set of x-values such that the function exists. Thus, the domain of the quadratic function is [tex]x \in \mathbb{R}[/tex]. [tex]\blacksquare[/tex]
Question 6The range of the function is defined by the set of y-values such that the function exists. Thus, the range of the quadratic function is [tex]y \in [-5, + \infty)[/tex]. [tex]\blacksquare[/tex]

h translates the parabola horizontally
If h > 0 then the translation is h units to the right.
If h < 0 then the translation is h units to the left.
If h = 0 then there is no horizontal translation.
k translates the parabola vertically
If k > 0 then the translation is k units up.
If k < 0 then the translation is k units down.
If k = 0 then there is no vertical translation.

Answer:
IM NOT. NNOT SURE BUT I THINK... the area may be 177? if i did it right, please check my equations though!
Step-by-step explanation:
so we first have to find the area of alllll the rectangles/squares in that weird squiggly shape
lets do the top
the width is 15 ft and the length is 5ft
so to find the area you have to do length times with so
A = lw
A = 15(5)
A = 75
so the first shape is 75
now lets do something real quick (im sorry this is all messed up infromation i have a dba (call) in like 16 mins and i gotta hurry. but illl come back if you need more explinations)
let first shape be f
let second shape be s
let third shape be t
let R be the area of the total shape
f + t + s = R
75 + t + s = R
now to find t
so the width would be 9ft and the length would be 8ft
A = lw
A = 9(8)
A = 72
75 + 72 + s = R
now to find s
the width is 5fth and the length is 6ft
A = lw
A = 6(5)
A = 30
now i think we add?
75 + 72 + 30 = R
75 + 102 = R
177 = R
i think the area is 177? (if i remeber how to do this correctly)
btw I will come back later and upload a pic of how i did it if you like. i must go now cause my teacher is gonna ask me civics questions and im so bad at that subject!!!!
