A 2-column table with 9 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2, 3, 4, 5, 6. The second

alexandr402 [8]

Answer:

(A)(0, 64)

Step-by-step explanation:

The local maximum of a function at a certain point in its domain is the value which is greater than or equal to the values at all other points in the immediate vicinity of the point.

Given the table:

$\left|\begin{array}{c|c}x&f(x)\\----&---\\-2&0\\-1&45\\0&64\\1&45\\2&0\\3&-35\\4&0\\5&189\\6&640\end{array}\right|$

From the table, (0,64) is a local maximum of the function f(x) as it is greater than the points around it.

Identify the k-value that makes the relationship shown in the table below proportional.

uysha [10]

Answer:

The value of k that makes the relationship shown in the table below proportional is $\mathbf{\frac{1}{2}}$

Step-by-step explanation:

The relation is proportional if $y=kx \:or\:k=\frac{y}{x}$

Putting values of x and y to find k.

For x =2 and y =1 k is: $k=\frac{y}{x}=\frac{1}{2}$

For x =4 and y =2 k is: $k=\frac{y}{x}=\frac{2}{4} =\frac{1}{2}$

For x =6 and y = 3 k is: $k=\frac{y}{x}=\frac{3}{6} =\frac{1}{2}$

For x = 8 and y = 4 k is: $k=\frac{y}{x}=\frac{4}{8} =\frac{1}{2}$

For x =10 and y = 5 k is: $k=\frac{y}{x}=\frac{5}{10} =\frac{1}{2}$

So, The value of k that makes the relationship shown in the table below proportional is $\mathbf{\frac{1}{2}}$

4(5x-6)=2(8x+10) how to solve

Pavel [41]

Hello! :)

Answer:

$\boxed{X=11}$

*The answer must have a POSITIVE sign!*

Step-by-step explanation:

Expand with distributive property: a(b+c)=ab+ac

4*5=20

6*4=24

20x-24

2*8=16

2*10=20

16x+20

20x-24=16x+20

First, you add by 24 both sides of an equation.

20x-24+24=16x+20+24

20x=16x+44

You subtract by 16x both sides of an equation.

20x-16x=16x+44-16x

4x=44

Then, you divide by 4 both sides of an equation.

4x/4=44/4

Divide by the numbers from left to right.

44/4=11

X=11 is the final answer

Hope this helps!

Have a nice day! :)
