Answer:

[tex]4*3=3*4[/tex]

Step-by-step explanation:

The commutative property of multiplication states that [tex]a*b=b*a[/tex].

In the first equation, we have that [tex]4*3=3*4[/tex], which is a clear application of the commutative property.

So, the answer is [tex]4*3=3*4[/tex] and we're done!

Answer:

it's the first one cause the commutative property is multiplying in any order without changing the product.... I think?

24.1 units

Step-by-step explanation:

Step-by-step explanation:

in essence, these 2 points are the Hypotenuse of a right-angled triangle. the legs are the coordinate differences between the 2 points creating the 3rd point of that triangle at (-10, 7) : the x coordinate of one point, and the y coordinate of the other.

now, we are looking for the midpoint. this midpoint cuts the original line/hypotenuse in half creating a scaling factor of 1/2.

when we create now a similar triangle based on that "half- Hypotenuse", we need to use the same scaling factor also on the legs (the coordinate differences).

so, when we cut the coordinate differences also in half, we get the coordinates for the midpoint on the main line.

xm, ym are the coordinates of the midpoint.

xm = (x1 + x2)/2 = (-10-3)/2 = -13/2 = -6.5

ym = (y1 + y2)/2 = (-6+7)/2 = 1/2 = 0.5

so, the midpoint is (-6.5, 0.5)

Answer:

The slope is undefined.

Step-by-step explanation:

If the x value stay the same between a set of points, the slope of the line will be undefined.

Answer:

Step-by-step explanation:

Find the zeroes of the function f ( x ) = x 2 + 12 x + 32

First, because it's a polynomial, factor it f ( x ) = ( x + 8 ) ( x + 4 )

Then, set it equal to zero 0 = ( x + 8 ) ( x + 4 )

Set each factor equal to zero and the answer is x = − 8 and x = − 4 .

4x^2 y^3 × 2xy^4 =

4 × 2 × x^2 × x^1 × y^3 × y^4 =

8 × x^(2 + 1) × y^(3 + 4) =

8 × x^3 × y^7 =

8x^3 y^7

Answer:

  3

Step-by-step explanation:

The square root function (√) only gives positive values, so graphs 1 and 4 make no sense.

When x = -3, the y-value is 0, consistent with graph 3.

Step-by-step explanation:

x=almonds

y=walnuts

z=cashews

9514 1404 393

Answer:

Step-by-step explanation:

We can let a, w, c represent pounds of almonds, walnuts, and cashews, respectively. Then the given relations are ...

  a +w +c = 10 . . . . . total pounds of nut mix

  a = 2w . . . . . . . . . twice as many almonds as walnuts

  1.25a +2.75w +3.15c = 18.90 . . . . total cost of the mix

__

Solving the system of equations can proceed by any of the methods you have learned for systems of two equations in two unknowns. Substitution, elimination, and matrix methods all work. Graphing methods are also available.

We can easily reduce this system to two equations in two unknowns by using the second equation to substitute for 'a'.

  2w +w +c = 10   ⇒   3w +c = 10

  1.25(2w) +2.75w +3.15c = 18.90   ⇒   5.25w +3.15c = 18.90

Solving the first of these equations for c, then substituting into the second of these equations gives ...

  c = 10 -3w

  5.25w +3.15(10 -3w) = 18.90

  -4.20w +31.50 = 18.90 . . . . simplify

  12.60 = 4.20w . . . . . . . . . . . add 4.20w -18.90

  3 = w . . . . . . . . . . . . . . . . . . . divide by 4.20

  c = 10 -3(3) = 1 . . . . . . . . . . . use the expression for c

  a = 2(3) = 6 . . . . . . . . . . . . . use the expression for a

The nut mix used 6 pounds of almonds, 3 pounds of walnuts, and 1 pound of cashews.

Additional comment

The attached graph shows one way to obtain a graphical solution. The first and third equations were solved for c, and those expressions were set equal to obtain the graph for the red line. The blue line is the second equation. Here, we have used (x, y) for (a, w). The solution for these variables is (a, w) = (6, 3). Using the first expression for c gives c = 10 -(6+3) = 1. This is the same solution as above.

Answer: 7 miles per hour

Step-by-step explanation:

3 1/2 miles = 7/2 miles

1/2 hours= 30 minutes

So,

In 30 mins, travelled 7/2 miles

In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles

In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.

Hence, the speed is 7 miles per hour.

Answer:

10 and 12

Step-by-step explanation:

10 and 12

if I divide 3 and 6 by 3 I get 1/2

if I divide 5 and 10 by 5 I get 1/2

1/2 is the first one listed

I cannot reduce 10/12 and get 1/2, I get 5/6

Answer:

$38 for 2 sweaters

Step-by-step explanation:

Every price for all other sweater options are divisible by 24, since it is the unit price (meaning 1 sweater = $24). 38 is not divisible by 24, but by 19. This means it does not follow the unit price. It would be a special sale.

Step-by-step explanation:

Answer:

Unit Cost = 0.6

Cost for 50 mile taxi ride = $30

Step-by-step explanation:

We are given the following information in the question:

Length of taxi ride = 28 miles

Time taken by taxi ride = 42 minutes

Cost of taxi ride = $16.80

We have to find cost of a 50 mile ride.

In order to do so, we have to find the unit cost of distance covered by ride which is the unit cost per mile of the ride that is the cost for 1 mile of taxi ride.

Our Formula:

Unit Cost = Cost for 1 mile of taxi ride = cost of taxi ride / distance covered by taxi ride

Using the values given we can use the formula so

unit cost = 16.80 / 28 = 0.6

Cost of 50 mile taxi ride

0.6 x 50 = 30

Henc costing $30 for a 50 mile taxi ride
