Step-by-step explanation:

The difference between associative and commutative property is that:

a} In Associative property numbers can be grouped in any way and yet the answer will be same.

<em> </em><em>E</em><em>x</em><em> </em><em>1</em><em>;</em><em> </em><em>(</em><em>2</em><em>+</em><em>3</em><em>)</em><em>+</em><em>2</em><em> </em><em>o</em><em>r</em><em> </em><em>(</em><em>2</em><em>+</em><em>2</em><em>)</em><em>+</em><em>3</em><em> </em><em>g</em><em>i</em><em>v</em><em>e</em><em>s</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>s</em><em>a</em><em>m</em><em>e</em><em> </em><em>r</em><em>e</em><em>s</em><em>u</em><em>l</em><em>t</em><em> </em><em>i</em><em>.</em><em>e</em><em>.</em>

<em>E</em><em>x</em><em> </em><em>2</em><em>;</em><em> </em><em>(</em><em>2</em><em>*</em><em>3</em><em>)</em><em>+</em><em>2</em><em> </em><em>o</em><em>r</em><em> </em><em>(</em><em>2</em><em>+</em><em>2</em><em>)</em><em>*</em><em>3</em><em> </em><em>g</em><em>i</em><em>v</em><em>e</em><em>s</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>s</em><em>a</em><em>m</em><em>e</em><em> </em><em>r</em><em>e</em><em>s</em><em>u</em><em>l</em><em>t</em><em> </em><em>i</em><em>.</em><em>e</em><em>.</em><em> </em><em>1</em><em>2</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>

b} In Commutative property numbers can be arranged in any order yet the result is same

<em>E</em><em>x</em><em> </em><em>1</em><em>;</em><em> </em><em>2</em><em>+</em><em>6</em><em>+</em><em>1</em><em> </em><em>o</em><em>r</em><em> </em><em>1</em><em>+</em><em>2</em><em>+</em><em>6</em><em> </em><em>g</em><em>i</em><em>v</em><em>e</em><em>s</em><em> </em><em>t</em><em>h</em><em>e</em><em> </em><em>s</em><em>a</em><em>m</em><em>e</em><em> </em><em>r</em><em>e</em><em>s</em><em>u</em><em>l</em><em>t</em><em> </em><em>i</em><em>.</em><em>e</em><em>.</em><em> </em><em>9</em>

Find the distance between M(-1,-10) and P(-12,-3) * Round to the nearest tenth.
DedPeter [7]

Answer:

13.0 units

Step-by-step explanation:

To find the distance between two points, we use the formula

d = sqrt( (y2-y1)^2+ (x2-x1)^2)

   sqrt((-3--10)^2 + (-12--1)^2)

   sqrt( (-3+10)^2 + (-12+1)^2)

   sqrt( (7^2  + (-11)^2)

  sqrt( 49+121)

  sqrt( 170)

Find a linear equation whose graph is the straight line with the given property.
jeka57 [31]

Answer:

y = 3/4x - 9/8

Then read explanation and see here with 2 coordinates would make

if 3/4 = -6 then 1 = -8

y = -6x + c

-6 / 3/4  + 9/8 / - 0.5  = -2.25

therefore c = -2.25

y = -6x - 2.25

y = -6x - 9/4  and again 9/4 can be found easily if round up fraction decimal to 225/100 and divide by 4

Step-by-step explanation:

C1)    (0.5 , -0.75)

C2)   ( 1. -3.75)

y = mx + c

-3.75 - - 0.75  /   1 - 0.5  = -3.75 + 0.75 / 0.5

= -3 / 0.5 = m

m = -6

y = -6x + c

then this works given just one coordinate to solve for 1 or 2 sets given points

y - y1 = mx+c

y - - 0.75 =  0.75 (x - x1)

y + 0.75 = 0.75 (x - 0.5)

y + 0.75 = 0.75x - 0.375

y = 0.75 - 0.75   =  0.75x( - 0.375 - 0.75)

y = 0.75x -1.125

y = 3/4x - 9/8    as common denominators of 1125/1000 is 9/8 as we divide by  125 into the fraction as we start at 250 and check its half just like when finding common denominators we 1/4 the lower number and see if we can find its half or its double etc with the other num er as first step for 3sf numbers.

Find the coordinates of the turning point for the equation of the graph below y=x^2+14x+45
USPshnik [31]

Answer:

(- 7, - 4 )

Step-by-step explanation:

Given a quadratic in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the turning point is

x = - \frac{b}{2a}

y = x² + 14x + 45 ← is in standard form

with a = 1, b = 14 , then

x = - \frac{14}{2} = - 7

Substitute x = - 7 into the equation and evaluate for y

y = (- 7)² + 14(- 7) + 45 = 49 - 98 + 45 = - 4

coordinates of turning point = (- 7, - 4 )
