Answer:

since it's the lhs we are concerned about, i. e., Y axis, so it must be either up or down. now look at the question, it says 8x2 - (1), it means one lower value of y i. e., 1 unit down

The difference of two numbers, a and b, is 21. The difference of 5 times a and two times b is 18. What are the values of a and b

bixtya [17]

Answer:

The solution set is (-8, -29) (Answer E)

Step-by-step explanation:

Changing the given info into equations, we obtain:

a - b = 21 and

5a - 2b = 18

Let's use elimination by addition/subtraction. Multiply the first equation by -5 to obtain

-5a + 5b = -105

and then add this result to the second equation:

-5a + 5b = -105

5a - 2b = 18

-------------------------

3b = - 87

Dividing both sides by 3 yields:

b = -87/3 = -29

Now substitute -29 for b in a - b = 21

a - (-29) = 21, or a + 29 = 21. Then a = -8.

The solution set is (-8, -29) (Answer E)

PLEASE SOMEONE HELP ME

pentagon [3]

Answer:

(A)

Step-by-step explanation:

The graph of any function (of $x$ ) can be shifted horizontally by a number $h$ by replacing every $x$ in the function with $x - h$ . And, if we want to shift the graph vertically, we simply add the number we want to shift by (which I'll call $k$ ) to every output of the function.

Functionally, if we have any function $f(x)$

We can shift it horizontally by $h$ units and vertically by $k$ units by creating a function $g(x) = f(x - h) + k$ .

Notice that in this case, $g(x) = f(x - (-2)) - 4$ . So the graph of $f(x)$ is shifted 2 units to the left, and 4 units down.

Or if this is too abstract of an explanation, then notice

$\sqrt[3]{x + 2} - 4$ looks similar to $\sqrt[3]{x - h} - k$ . Specifically, if h = -2 and k = -4 (the graph is shifted two units left and 4 units down), then the function becomes equivalent to $g(x)$

A membership committee of three is formed from four eligible members. Let the eligible members be represented by A, B, C, and D.

yKpoI14uk [10]

The correct statement is:

There are four ways to choose the committee.
There are three ways to form the committee if person D must be on it.
If persons B and C must be on the committee, there are two ways to form the committee.

It is given that:

A membership committee of three is formed from four eligible members.

1) There are four ways to choose the committee.

This statement is true.

Since we have to choose 3 members out of the 4 members so we can use the method of combination.

2) There are three ways to form the committee if person D must be on it.

This statement is also true.

Since D has to be in the committee, this means we have to choose 2 more people out of the three people to form the committee.

3) If seven members are eligible next year, then there will be fewer combinations.

This statement is wrong.

Since we have to choose 3 members out of 7 members so the number of possible combinations will be:

There are 35 combinations possible.

4) If persons B and C must be on the committee, there are two ways to form the committee.

If B and C have to be in the committee then we have to choose just one person out of the two people left.

Hence, the statement is true.

5) If persons A and C must be on the committee, then there is only one way to form the committee.

If A and C have to be on the committee then as in the last option we have to choose any one of the two-person left.

So possible number of ways is 2.

Hence, the statement is false.
