Match each step with the property used to get to that step. (Note: the column that lists the algebraic expressions is already in

the correct order.)
(6x+3)-5x


1.(3+6x)-5x. Commutative
2. 3+(6x-5x). Multiplicative identity.
3. 3+(6-5)x. Associative
4. 3+(1)x. Subtraction

Answer:

Commutative property:

a+b= b+a for any a and b

Multiplicative identity:

a \cdot 1 = 1 \cdot a for any a.

Associative property:

a+(b+c) = (a+b)+c for any a, b and c

Distributive property:

a \cdot (b+c) = a\cdot b+ a\cdot c

Given the equation:

(6x+3)-5x

1.

Using commutative property:

(3+6x)-5x

2.

Using associative property.

3+(6x-5x)

3.

Using distributive property:

3+(6-5)x

4.

using subtraction.

3+(1)x

5.

Using Multiplicative identity:

3+x

Now, match each step with the property used to get to that step are as follow:

1. (3+6x)-5x           [Commutative property]

2. 3+(6x-5x)           [Associative property]

3. 3+(6-5)x             [Distributive property]

4.  3+(1)x                  [Subtraction]

5. 3+x                     [Multiplicative property]

(6x + 3) - 5x

(3 + 6x) - 5x.....commutative
3 + (6x - 5x).....associative
3 + (6 - 5)x...distributive
3 + 1x....subtraction
3 + x....multiplicative identity

15 points!! Please help! please explain how you got you answers
Lynna [10]

We observe that a line will pass through 3 points, but to find a slope we only need two.

We see that it passes through points (assuming the scale of graph is 1 : 1) P_1(x_1,y_1)=P_1(0,1) and P_2(x_2,y_2)=P_2(2,-1).

We can use slope formula that applies for any line and produce the same slope for any two different points on the line

m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-1}{2-0}=-1

So the slope is -1 also it intersects y-axis at n=1 so the general form of the linear function is

f(x)=mx+n

That is in your case

\boxed{f(x)=-x+1}

Hope this helps.

Rewrite the fraction using the least common denominator <br><br> 4/9 7/15
denis23 [38]

Answer:

20/45 & 21/45

Step-by-step explanation:

Find a common denominator. What you do to the denominator, you do to the numerator. In this case, the smallest denominator is 45.

(4/9)(5/5) = 20/45

(7/15)(3/3) = 21/45

The two fractions you have is:

20/45 for 4/9

21/45 for 7/15

If all pairs of consecutive angles of a quadrilateral are supplementary, then the quadrilateral is a parallelogram.
____ [38]
This is true.

It comes from the same side interior angles theorem which says that same side interior angles are supplementary, only if the lines are parallel.

Anyone here able to lend a helping hand?
elena55 [62]

Answer:

Step-by-step explanation:

1). Vertical intercept of the graph = Point at which the graph intersects the y-axis.

Therefore, vertical intercept is y = 1000.

In this situation vertical intercept means the initial dose of the drug taken = 1000 mg.

2). From the graph attached, point (x, y) represents,

x = Time 't' or duration

y = concentration of the drug after time 't'

Point (0, 1000) represents concentration = 1000 mg of the drug after t = 0 hour

Similarly, (1, 750) represents concentration = 750 mg after t = 1 hour

Therefore, fraction of drug remained = \frac{750}{1000}

                                                              = \frac{3}{4}

3). Let the equation, representing the concentration of the drug and time is,

y=a(b)^t

Here, a = Initial amount of the drug (at t = 0 hours)

            = 1000 mg

At (t = 1 hours), concentration of the drug = 750 mg

y=1000(b)^t

750=1000(b)^1

b=\frac{750}{1000}

b=\frac{3}{4}

Therefore, equation will be,

y=1000(\frac{3}{4})^t

A 12 sided number cube with the numbers 1 through 12 is rolled.Select from the drop down menu to correctly complete the statemen
ioda
The 12 sided cube with the numbers 1 to 12 is rolled. That means it can land on any number from 1 to 12. The number of total possible outcomes is 12. The number of favourable outcomes, that is, the number of times the cube lands on a number than 4 is 12-1=11.
Probability=Number of favourable outcomes/number of total possible outcomes
= 11/12
= 0.92
I really hope this helps! And pls mark it as brainliest.
