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]

Answer:

Slope formula:

RISE: y2(second y-coordinate) - y1(first y-coordinate)

        ____________________________________

RUN: x2(second x-coordinate) - x1(first x-coordinate)

y2 - y1 / x2 - x1

Plug in what we have in the order given in the formula:-

Therefore, 2 is the slope of this equation.

Answer:

Slope: 2

Step-by-step explanation:

Given points:

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:

2. Simplify the fraction. The quotient will be the slope of the line.

Thus, the slope of the line is 2.

The price that it cost to seed the inside of this track is $1,040.4

The formula for calculating the area of a rectangle is expressed as:

A  = length * width

Let the length be 51 and the width be 102 yd such that:

Area of the grass = 51 * 102
Area of the grass = 5202 square yard

If it costs $.25 per square yard to seed an area of grass, the price fror the area inside the track is:

Price = 0.2 * 5202
Cost of the track = $1,040.4

Hence the price that it cost to seed the inside of this track is $1,040.4

IF THE TEMPERATURE WAS -5° AT 5:00 am., WHAT WAS THE TEMPERATURE AT 9:00 am?

Answer:

a)  y = (x - 3)²

b)  y = x² - 4

c)  y = (x + 2)²

d)  y = x² + 5

e)  y = (x + 6)² - 7

f)  y = (x - 2)² + 5

Step-by-step explanation:

Parent equation:  y = x²

Transformed equation:  y = (x - h)² + k

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.

a) The parabola moves 3 units to the right:  

⇒ y = (x - 3)² + 0

⇒ y = (x - 3)²

b) The parabola moves 4 units down:

⇒ y = (x - 0)² - 4

⇒ y = x² - 4

c) The parabola moves 2 units left:  

⇒ y = (x + 2)² + 0

⇒ y = (x + 2)²

d) The parabola moves 5 units up:  

⇒ y = (x - 0)² + 5

⇒ y = x² + 5

e) The parabola moves 7 units down and 6 units left:  

⇒ y = (x + 6)² - 7

f) The parabola moves 2 units right and 5 units up:  

⇒ y = (x - 2)² + 5

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

b) 546

Step-by-step explanation:

We need to try to factor the polynomial.

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:

[tex]\begin{aligned}\implies 6(10)^2-5(10)-4&=600-50-4\\&=546\end{aligned}[/tex]

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!!!!

Q1: Solutions: x = 2 and x = 4, Axis of symmetry: x = 3.

Q3: (x, y) = (-3, 5).

Q4: A parabola cannot have both a minimum and maximum point because it is only bounded by its vertex.

Q5: [tex]x \in \mathbb{R}[/tex]

Q6: [tex]y \in [-5, + \infty)[/tex]

Graphically speaking, second order polynomials are represented by parabolas. In this question we must interpret the graphs to find all the required information.

The 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]

The 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]

A parabola cannot have both a minimum and maximum point because it is only bounded by its vertex. [tex]\blacksquare[/tex]

The 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]

The 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]
