Answer:

D, 2; 5

Step-by-step explanation:

Sum the equations vertically to eliminate at least one variable.

You will obtain 8y = 40.

Divide both sides by 8. You will get y = 5.

Now we know the value or y. Substitute this value into the second equation (-6x+4y = 8). You will get -6x+(4×5) = 8. Multiply 4 and 5: -6x+20 = 8.

Solve for x by moving 20 to the other side and switching sign: -6x = 8-20.

So: -6x = -12 and therefore x = 2.

So now we know the value of x and y.

(x; y) = (2; 5)

Answer:

Channel 9 conducting this interview would be an example of a convenience sample.

Step-by-step explanation:

Convenience sampling is a kind of non-probability sampling (i.e. all items does not have an equivalent chance of being selected), which does not comprises of random collection of items.

Convenience sampling is where we take in items which are easy to reach.

For instance, gathering information on customer satisfaction by interviewing 6 randomly selected customers from a local store is an illustration of convenience sampling.

In this case Channel 9 selected a very easily available sample. Since, the elderly viewers are usually retired and can be reached easily either at home or on the phone, the sampling method used is convenience sample.

Answer:

2 = 1 + 1

3 = 2 + 1

5 = 3 + 2

8 = 5 + 3

13 = 8 + 5

21 = 13 + 8.

Fibonacci numbers are found in many structures in nature.

We have just found that these cacti enclose Fibonacci numbers 13 and 21.

Answer:

80%

Step-by-step explanation:

% is out of 100 so make the denominator of 4/5 to be 100:

4/5 times 20/20 = 80/100 = 80%

Answer:

80%

Step-by-step explanation:

4 divided by 5 equal .8

.8 x 100 equals 80

It's multiplied by 100 because usually percentages are out of 100.

OR

You can move the decimal in .8 to 2 space to the right

Answer: (-1,2)

Step-by-step explanation:

Step-by-step explanation: Lines up nicely with points A & D.

Answer:

48 in^2

Step-by-step explanation:

To find the area of a triangle is (1/2)*base*height, so (1/2)*4in*24in = 2in*24in = 48 in^2.

Answer:

48 in2

Step-by-step explanation:

when finding area we use the equation A= 1/2bh

b meaning base and h meaning height

so for this we would use A= 1/2(24)(4)

multiply them both to get A=1/2(96)

and then take half of 96 to get 48

so the answer is 48in 2

Answer:

Part 1:

Domain= {2,3,8,9}

Range = {7,9,14}

Part 2: Yes it is not a function

Step-by-step explanation:

Domain is the first number

Range is the second.

Domain= {2,3,8,9}

Range = {7,9,14} ( Notice that 14 is noted twice so just put it as once and this is not part of the answer)

Function: Is any of the domain numbers the same: Answer Yes it's a function.

Final Answer: [tex]x = 12[/tex]

Steps/Reasons/Explanation:

Question: The equation, [tex]6x + 12 = 8x - 12[/tex] has one solution. Solve the equation and show and describe all the steps to show that the solution is of the form [tex]x = a[/tex].​

Step 1: Subtract [tex]6x[/tex] from both sides.

[tex]12 = 8x - 12 - 6x[/tex]

Step 2: Simplify [tex]8x - 12 - 6x[/tex] to [tex]2x - 12[/tex]

[tex]12 = 2x - 12[/tex]

Step 3: Add [tex]12[/tex] to both sides.

[tex]12 + 12 = 2x[/tex]

Step 4: Simplify [tex]12 + 12[/tex] to 24.

[tex]24 = 2x[/tex]

Step 5: Divide both sides by [tex]2[/tex].

[tex]\frac{24}{2} = x[/tex]

Step 6: Simplify [tex]\frac{24}{2}[/tex] to [tex]12[/tex].

[tex]12 = x[/tex]

Step 7: Switch sides.

[tex]x = 12[/tex]

Answer:

x ≥ 3

Step-by-step explanation:

the domain of a graph consists of all the input values shown on the x -axis

The domain of the square root function graphed below would be x ≥ 3

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable , functions are indispensable for formulating physical relationships.

The domain is all  real numbers for x>3 and the range of the square root function graphed is equal to the interval------> [1,∞)

so, the range is all real numbers for x>3

Hence, the domain of a graph consists of all the input values of the x -axis.

Step-by-step explanation:

when adding or subtracting fractions, we will always want the denominators to be the same.

Answer: x= 108

Step-by-step explanation: The triangle is an isosceles triangle, so the two sides are parallel which means the other angle equals to 72 as well. Now we take the triangle rule and do 180-72-72= 36 (the top angle= 36). The triangles are all equal so that means the other angle (in the upside down one) also equals 72 so we take 36+72= 108. Since it is also a parallelogram, the angles are equal.
