Which expression is equivalent to

Answer:

Shape 2 and 3

Step-by-step explanation:

shape 1 is not enclosed so it cannot have area

[tex]\dfrac{10}{1+2i}\\\\\\=\dfrac{10(1-2i)}{(1+2i)(1-2i)}\\\\\\=\dfrac{10-20i}{1 - (2i)^2}\\\\\\=\dfrac{10-20i}{1+4}~~~~~;[i^2 =-1]\\\\\\=\dfrac{10-20i}5\\\\=\dfrac{10}5 - \dfrac{20i}5\\\\=2-4i[/tex]

Answer:

Rate of change is correct; it's -3. And when the x-value is 8, the y-value is just a value, not a coordinate point. It's one number. -3 would not be the answer, and i dont know what the answer would be, but it's between greater than -14 and less than -23. Hope this helps!!

[tex] = \: \: 10 {a}^{4} + 10 {a}^{3} - 10 {a}^{2} [/tex]

Answer:

The domain is all the x values and the range is all the y values.

Since there are 6 points on the figure, just find the coordinates (x, y) for all the points. Then get all the x and y values separated in a table.

I'm just going to assume this is scaled by 1 unit per square

Here are all the points on the graph:

(-6, -1)

(-4, 3)

(-4, -6)

(0, 2)

(2, -2)

(5, 7)

Now just split them into their x and y values

The Domain: -6, -4, 0, 1, 5

The Range: -1, 3, -6, 2, -2, 7

Answer:

Interval notation

Step-by-step explanation:

The domain is the x-value on the x-axis. The range is the y-value on the y-axis.

Find the two highest points on opposite sides in the graph.

After this step has been completed, you can write it in different forms, for example in interval notation:

The domain would be [-6, 5]

The range would be [-1, 7]

Note - for interval notation, when the point is a closed circle, the ending parenthesis would be "[ "or "]". However, when it is an open circle, the parenthesis would be "( "or ")".

Answer:

b) g(x) = Five-sevenths (three-fifths) Superscript negative x

Step-by-step explanation:

both ranges are y<0, you can clearly see this if you plug all of the equations into a graphing calculator

A domain of a function has to do with the set of all possible inputs in a function and contains real numbers.

This refers to the relation or expression that has to do with a number of variables for example, "bx + c" is a function.

Hence, we can see that your question is incomplete so I gave you a general overview to help you get a better understanding of functions and domains.

Step-by-step explanation:

The equation can be rewritten as

37=9-7x

Subtract 9 from both sides

28=-7x

Divide both sides by 7

4=-x

This means that X is equal to -4

Step-by-step explanation:

1. 3 cans cost 90 cents

3=0.90 & x=2.7

by ratio:

3/0.9 = x/2.7

0.9x=8.1

x= 9

So you can buy 9 cans for 2.7 dollars

2. 10 Juice cost 3 dollars

by ratio:

10/3 = 4/x

10x=12

x=1.2

so you will spend 1.2 dollars to buy 4 juice packs

The height of the triangle is 15 meters.

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

Types of triangles

Area of a triangle = 1/2 (base x height)

height = (2 x area ) / base

(2 x 67.5) / 9

= 135 / 9

= 15 meters

Answer:

this is easy 100% in this case equals 100 so 15 Juveniles equals 15%

Step-by-step explanation:

Answer:

y= -1/4x + 2

Step-by-step explanation:

so basicly find the slope first which is "m"

to do that do rise/run or do y2-y1/x2-x1

rise over un in this case is -1/4

slope is negative so its -1/4 = m

that find y intercept which is "b"

in this case its 2

then put it in formula

y=mx+b

y= -1/4x + 2
