The United States has a population of approximately 323 million people. What is this number written in scientific notation?

Answer:

6

Step-by-step explanation:

2x+4=16

2x=12

x=6

Answer: x = 6

Step-by-step explanation: To solve for x, we must first

isolate the term containing x, which in this problem is 2x.

Since 4 is being added to 2x, we subtract 4

from both sides of the equation to isolate the 2x.

On the left, the +4 and -4 cancels

out and on the right, 16 - 4 is 12.

So we have 2x = 12.

Then just divide both sides by 2 so x = 6.

Answer:

Since x=3 and y=2, plug into the equation.

4(3)²-2(2)

= 4(9)-4

= 36-4

= 32

Answer:

you are trying to get up to 180 ( a straight line is 180 degrees).

So 26+32 =58 and go through your answer choices to see which one adds up to 180

and it that case your answer would be A 122+58=180

Answer and explanation:

The domain would be [-9,3]. A closed circle lets you know if you will have to put parenthesis or a bracket when writing the domain. You can use every number between -9 and 3, including -9 and 3.

The domain of the given graph is  -9 ≤ x ≤ 3.

The domain of a function f is the set of all values of x for which f(x) is defined and real.

Now from the given graph it is seen that the graph runs from -9 to 3 on x-axis.

and it is known that the domain of the graph is the set of all possible values of x.

Hence the required domain the given graph is written as,

-9 ≤ x ≤ 3

Thus, the domain of the given graph is  -9 ≤ x ≤ 3.

Answer: 60 yd

Step-by-step explanation:

Here: subdivided into 3 smaller pens (2w + w + w) extra widths for separation purposes (3 smaller pens)

180 yards of fencing material

180yd = 2L + 4w

180dy = 2*60 + 4w

60dy = 4w

w = 15yd, how wide can the rectangle can  be with L = 60yd

Answer:

23

Step-by-step explanation:

2y=46

y=46/2

y=23

hope this helps!!

Answer:

Y=23

Step-by-step explanation:

If you follow pemdas then you know you have to divide both sides by 2 because its oppisite and when you divide 46 by 2 you get 23 and 2y divided by 2 would be 1y also just known as y and your answer is 23=y

Answer: y= -5/7 x + 1/7

Step-by-step explanation:

Answer:

[tex]y=-\frac{5}{7} x+\frac{1}{7}[/tex]

Step-by-step explanation:

Equation of a line: [tex]y = mx+b[/tex]

m is the slope, and b is the y-intercept.

m = [tex]\frac{rise}{run} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{-2-3}{3-(-4)} =-\frac{5}{7}[/tex]

Now, we have [tex]y=-\frac{5}{7} x+b[/tex]

We can insert one set of points in to solve for b.

We will use the first point (-4, 3):

[tex]3=-\frac{5}{7} (-4)+b[/tex]

[tex]\frac{5}{7}* \:4+b=3[/tex]

[tex]\frac{20}{7}+b=3[/tex]

[tex]b=\frac{1}{7}[/tex].

Equation:[tex]y=-\frac{5}{7} x+\frac{1}{7}[/tex]

Answer:

1. Commutative Property of Addition

2. Distributive property

Step-by-step explanation:

Given

[tex]Line 1: 4(8+9x)[/tex]

[tex]Line 2: 4(9x+8)[/tex]

[tex]Line 3: 36x+32[/tex]

Required

Justify each step

From Line 1 to 2:

The property from Line 1 to 2 depicts [tex]a + b = b + a[/tex];

i.e.

[tex]4(8 + 9x) = 4(9x + 8)[/tex]

This is referred to as Commutative Property of Addition

From Line 2 to 3:

The property here depicts [tex]a(b + c) = a * b + b * c[/tex]

i.e.

[tex]4(9x + 8) = 4 * 9x + 4 * 8[/tex]

[tex]4(9x + 8) = 36x + 32[/tex]

This is referred to as Distributive property

Answer:

Line 1 to Line 2: Commutative Property of Addition

Line 2 to Line 3: Associative Property of Addition

Answer:

Step-by-step explanation:

(1) [tex]50y^3=5y\cdot 10y^2[/tex], and

[tex]10y^2\cdot(5y-4)=50y^3-40y^2[/tex]

Subtract this from [tex]50y^3+10y^2-35y-7[/tex] to get a remainder of

[tex](50y^3+10y^2-35y-7)-(50y^3-40y^2)=50y^2-35y-7[/tex]

What we've done here is show that

[tex]\dfrac{50y^3+10y^2-35y-7}{5y-4}=10y^2+\dfrac{50y^2-35y-7}{5y-4}[/tex]

We can keep going as long as the degree of the remainder's numerator is at least the same as the degree of its denominator.

Next, [tex]50y^2=5y\cdot 10y[/tex], and

[tex]10y\cdot(5y-4)=50y^2-40y[/tex]

Subtract this from the previous remainder to get a new remainder of

[tex](50y^2-35y-7)-(50y^2-40y)=5y-7[/tex]

which means

[tex]\dfrac{50y^3+10y^2-35y-7}{5y-4}=10y^2+10y+\dfrac{5y-7}{5y-4}[/tex]

Finally, [tex]5y=5y\cdot1[/tex], and

[tex]1\cdot(5y-4)=5y-4[/tex]

Subtract this from the previous remainder to get

[tex](5y-7)-(5y-4)=-3[/tex]

So we end up with

[tex]\dfrac{50y^3+10y^2-35y-7}{5y-4}=\boxed{10y^2+10y+1}-\dfrac3{5y-4}[/tex]

(the quotient is the expression in the box)

(2) Using the same process as before:

[tex]8m^4=2m\cdot4m^3[/tex]

[tex]4m^3\cdot(2m+1)=8m^4+4m^3[/tex]

[tex](8m^4-4m^2+m+4)-(8m^4+4m^3)=-4m^3-4m^2+m+4[/tex]

[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-\dfrac{4m^3+4m^2+m+4}{2m+1}[/tex]

[tex]-4m^3=2m\cdot(-2m^2)[/tex]

[tex]-2m^2\cdot(2m+1)=-4m^3-2m^2[/tex]

[tex](-4m^3-4m^2+m+4)-(-4m^3-2m^2)=-2m^2+m+4[/tex]

[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-2m^2-\dfrac{2m^2-m-4}{2m+1}[/tex]

[tex]-2m^2=2m\cdot(-m)[/tex]

[tex]-m\cdot(2m+1)=-2m^2-m[/tex]

[tex](-2m^2+m+4)-(-2m^2-m)=2m+4[/tex]

[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-2m^2-m+\dfrac{2m+4}{2m+1}[/tex]

[tex]2m=2m\cdot1[/tex]

[tex]1\cdot(2m+1)=2m+1[/tex]

[tex](2m+4)-(2m+1)=3[/tex]

[tex]\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=\boxed{4m^3-2m^2-m+1}+\dfrac3{2m+1}[/tex]
