Which of the following best shows the commutative property of multiplication?
4 x 3 = 3 x 4
4 x 3 = 4
4 x 3 = 4 ÷ 1/3
4 x 3 = (2 x 2) x 3
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?

How to find the rational zeros of a function
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 .

Which of the following does NOT have a unit price of $24 for one sweater?
$38 for 2 sweaters
$72 for 3 sweaters
$96 for 4 sweaters
$120 for 5 sweaters
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.
Doug entered a canoe race. He rowed 3 1/2 miles in 1/2 hour what is his average speed in miles per hour
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.

Find the midpoint of the segment with the given endpoints.
(-10,- 6) and (-3,7)
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)
A mixed nuts factory makes a 10 pound mixture of almonds, walnuts, and
cashews. Almonds cost $1.25 per pound, walnuts cost $2.75 per pound,
and cashews cost $3.15 per pound. The mixture calls for twice as many
almonds as walnuts. The total cost of the mixture is $18.90. How much of
each ingredient did the store use?
This is a System of equations problem
Answer
x+y+z=10
1.25x+2.75x+3.15x+18.90
x=2z
Step-by-step explanation:
x=almonds
y=walnuts
z=cashews

Answer:
6 pounds almonds3 pounds walnuts1 pound cashewsStep-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.

At a little-known vacation spot, taxi fares are a bargain. A 28-mile taxi ride takes 42 minutes and costs $16.80. You want to find the cost of a 50-mile taxi ride. What unit price do you need?
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

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.
