Answer:

k = 5

Step-by-step explanation:

3x + k

im going to replace the x with the numbers that go there

3 x 1 + k = 8

3 x 1 = 3

8 - 3 = 5

k = 5

3 x 3 + k = 14

3 x 3 = 9

14 - 9 = 5

k = 5

3 x 5 + k = 20

3 x 5 = 15

20 - 15 = 5

k = 5

Answer: z = -11

isolate the variable to solve

Answer:

z= -11

Step-by-step explanation:

add 7 to both sides: -18+7 = z

simplify: -11 = z

Answer:

not a function

Step-by-step explanation:

if x values repeat its not a function

Moving the vertices does not affect the relationship between the diagonals. They bisect each other in all cases.

Answer:

Despite changing the vertices, the opposite sides and opposite interior angles of the parallelogram remain equal.

Step-by-step explanation:

Answer:

y = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Given that y varies inversely with x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition y = [tex]\frac{1}{3}[/tex] when x = [tex]\frac{1}{2}[/tex] , thus

[tex]\frac{1}{3}[/tex] = [tex]\frac{k}{\frac{1}{2} }[/tex] = 2k ( divide both sides by 2 )

k = [tex]\frac{1}{6}[/tex]

y = [tex]\frac{1}{6x}[/tex] ← equation of variation

When x = [tex]\frac{1}{4}[/tex] , then

y = [tex]\frac{1}{6(\frac{1}{4}) }[/tex] = [tex]\frac{1}{\frac{3}{2} }[/tex] = [tex]\frac{2}{3}[/tex]

Answer:

43

Step-by-step explanation:

Answer: twenty-three . seven hundred fourty-nine

fourty = 4

nine = 9

Answer:

W1=0.875.

W2= -1.14

Step-by-step explanation:

(8w-7)(7w+8)

8w(7w+8)-7(7w+8)

56w^2+64w-49w-56

56w^2+15w-56

Solve it by quadratic equation

a=-b+-√(b^2-4ac)/2a

Substitute the values

And you will get 2 answers

a=-56

b=15

c=56

10^-5 = 1/100,000

10^20 = 100,000,000,000,000,000,000

10^-12 = 1/1,000,000,000,000

10^0 = 1

10^3 = 1,000

10^-85 =  a very tiny number (basically 0)

Answer: 10^-85, 10^-12, 10^-5, 10^0, 10^3, 10^20

You can also see that it goes in order so the higher the power, the larger the number.

Answer:

b = 1

Step-by-step explanation:

Move all terms that don't contain  b  to the right side and solve.

Answer:

Add  

8 b  and  2 b =10 b

Step-by-step explanation:

because 8+2 = 10

and the are alike terms

they both have b so that means they are alike terms

hope this helped

Answer:

b = - 6

Step-by-step explanation:

Using the rules of exponents

[tex](a^{m}) ^{n}[/tex] ⇔ [tex]a^{mn}[/tex]

[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

Thus

[tex](y^{b}) ^{4}[/tex] = [tex]y^{4b}[/tex] = [tex]\frac{1}{y^{24} }[/tex] = [tex]y^{-24}[/tex], then equating the exponents

4b = - 24 ( divide both sides by 4 )

b = - 6

Answer:

20 cm

Step-by-step explanation:

the square root of 400 is 20

since all 4 sides are equal and the formula is area = L X B

20 x 20 is 400

Answer:

(3x +2)° + 28° = 180°

=> 3x + 30 = 180

=> 3x = 180–30

=> x = 150/3

=> x = 50

Answer:

  97 ft

Step-by-step explanation:

The Pythagorean theorem is useful for working problems like this. It tells you the relationship between side lengths and the hypotenuse of a right triangle.

Here, the building is presumed to be perpendicular to the ground, so the 100' rope is the hypotenuse of a triangle with legs equal to 23' and the height of the building (b).

  23² +b² = 100²

  b = √(10000 -529) ≈ 97.32

The height of the building is about 97 feet.

Answer:

330.76

Step-by-step explanation:

Answer:

A. 0

General Formulas and Concepts:

Perpendicular Lines always have 1 solution.

Parallel Lines always have no solution.

Same Lines always have infinite amount of solutions.

Step-by-step explanation:

We see from the graph given that the 2 lines are parallel. Since they are parallel, they will never intersect.

Therefore, we would have no solution, or 0 solutions, as our answer.

Answer: 3,917

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

So, again, from the most right column, we can add 5, -6, and -2 to get -3. We now know that every row or column must be equal to -3.

The question is asking if the number square below is -3. We found out from above that is -3 so it's true.

Answer:

A function's zeros can be determined by setting each linear factor equal to 0 and solving.

Step-by-step explanation:

This is because in finding the zero's of a quadratic function, we factorize the quadratic function to obtain its linear factors. Then, each linear factor is then equated to zero to solve for the zeros of the quadratic function.

The solution of the equating to zero of the linear factors give the zeros of the quadratic function.

Answer:  3, 5, 7

Step-by-step explanation:

There is a "trick" to determine divisibility by 3: if the sum of the digits is divisible by 3, the number is divisible by 3.

3 + 1 + 5 = 9 which is a multiple of 3, so 315 is divisible by 3.

It works for 9 also. since the sum of the digits is 9, 315 is divisible by 9.

Divisibility by 5: any number that has the units digit 5 or 0 is divisible by 5.

For 7, I just tried it  315÷7= 45

Only even numbers are divisible by 2.

If a 3-digit number is divisible by 11, the middle digit will be the sum of the first and last digits.   (That is not the case for 315)  But 385 is divisible by 11, also 495, 253, and many others you can try for fun.
