Answer:

B

Step-by-step explanation:

Plug in coordinates to see if they match the answer.

It's easier in slope-intercept form, so lets change it first.

-2x+y=7

+2x    +2x

y=2x+7

Now we can plug in the coordinates to see if they match.

Lets try A.

11=2(-2)+7

11=-4+7

11=3

A is incorrect.

Lets try B.

11=2(2)+7

11=4+7

11=11

B is a solution, therefore is on the graph.

For the given equation, y = 4(x) - 1, what is the value of y for x = 2?
Alik [6]

Answer:

The answer is D (7).

Step-by-step explanation:

If you plug in 2 where x is, you get 4*2 -1, which is 8-1, which equals to 7.

13) If AOBC is a rectangle whose three vertices are A(0,3), (0,0) and B(5,0).
Levart [38]

Answer:

(b) 68

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, (x_1,y_1) and (x_2,y_2). The distance between them is given by:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Diagonal:

Diagonals are a line between opposite points in a square.

In this question, it is between A(0,3) and B(5,0), and between (0,0) and (5,3). Both these diagonals have the same measure, and are the distance between these points. So

D = \sqrt{(5-0)^2+(3-0)^2} = \sqrt{5^2 + 3^2} = \sqrt{34}

Then sum of the squares of its both diagonals is units

Both diagonals measure \sqrt{34}. Sum of squares is:

(\sqrt{34})^2 + (\sqrt{34})^2 = 34 + 34 = 68

The correct answer is given by option b.

Find an expression for a rational function f(x) that satisfies the conditions: a slant asymptote of y = 2x, vertical asymptote a
lesantik [10]

Complete Question

The complete Question is attached below

Answer:

Option D

Step-by-step explanation:

From the question we are told that:

Slant asymptote of y = 2x

Vertical asymptote at x = 1,

Points (0,6)

Generally the Denominator  is give as

With

Vertical Asymptote at

x -1=0

Therefore

Denominator = (x-1)

Generally Slant asympote 2x Gives the Coefficient of the numerator

Therefore

The expression for a rational function f(x) that satisfies the conditions

F(x)=\frac{2x^2-2x-6}{x-1}

Option D
