Answer:

a = 5

Step-by-step explanation:

According to the factor theorem, if x + 2 is a factor, then by dividing the polynomial by the binomial, we are meant not to have a remainder

In this case, the remainder would be zero

So, if we set the binomial equals zero and substitute the x-value into the polynomial, we are supposed to have 0

So we have this as;

x + 2 = 0

x = -2

-2^3 -2(-2)^2 -2(a) + 6 = 0

-8-8-2a + 6 = 0

-16 + 2a + 6 = 0

2a -10 = 0

2a = 10

a = 10/2

a = 5

Answer:

JL is not congruent to KM

Step-by-step explanation:

The length of JL is 23-21 = 2.

The length of KM is 25-22 = 3

So, because the lengths are not equal,

JL is not congruent to KM

The graph of y=√x is shifted 2 units up and 5 units left, Which equation represents the new graph?

Zinaida [17]

y = √(x + 5) + 2

<h3>Further explanation</h3>

<u>Given:</u>

The graph of $y = \sqrt{x}$ is

shifted 2 units up, and
5 units left.

<u>Question:</u>

Which equation represents the new graph?

<u>The Process:</u>

The translation is a form of transformation geometry.

Translation (or shifting): moving a graph on an analytic plane without changing its shape.

In general, given the graph of y = f(x) and v > 0, we obtain the graph of:

$\boxed{ \ y = f(x) + v \ }$ by shifting the graph of $\boxed{ \ y = f(x) \ }$ upward v units.
$\boxed{ \ y = f(x) - v \ }$ by shifting the graph of $\boxed{ \ y = f(x) \ }$ downward v units.

That's the vertical shift, now the horizontal one. Given the graph of y = f(x) and h > 0, we obtain the graph of:

$\boxed{ \ y = f(x + h) \ }$ by shifting the graph of $\boxed{ \ y = f(x) \ }$ to the left h units.
$\boxed{ \ y = f(x - h) \ }$ by shifting the graph of $\boxed{ \ y = f(x) \ }$ to the right h units.

Therefore, the combination of vertical and horizontal shifts is as follows:

$\boxed{\boxed{ \ y = f(x \pm h) \pm v \ }}$

The plus or minus sign follows the direction of the shift, i.e., up-down or left-right.

- - - - - - - - - -

Let's solve the problem.

Initially, the graph of $y = \sqrt{x}$ is shifted 2 units up.

$\boxed{y = \sqrt{x} \rightarrow is \ shifted \ 2 \ units \ up \rightarrow \boxed{ \ y = \sqrt{x} + 2 \ }}$

Followed by shifting 5 units left.

$\boxed{y = \sqrt{x} + 2 \rightarrow is \ shifted \ 5 \ units \ left \rightarrow \boxed{ \ y = \sqrt{x + 5} + 2 \ }}$

Thus, the equation that represents the new graph is $\boxed{\boxed{ \ y = \sqrt{x + 5} + 2 \ }}$

The answer is A.

Mr. linton will read 100 pages a day until he finishes the book. Mr. linton thinks it will take seven days to finish the book. I

lakkis [162]

Answer:

No Mr.Linton will not take 7 days to finish the book

Explanation

Since the book has 900 pages, you will have to divide 900 by 100 which equals 9. 9 is the number of days it will take for Mr.Linton to read the book. Therefore he is wrong.
