Write the standard form of the equation of the line through the given point with the given slope. point (-1.0); slope -2/3

Answers

Answer:

Step-by-step explanation:

When given a point and a slope, the best equation to use is the point-slope formula, y - k = m(x - h)

which here becomes:

y - 0 = m(x + 1), or y = (-2/3)(x + 1), or y = (-2/3)x - 2/3

If you want this in standard form, first clear the fractions by multiplying all terms by 3: 3y = -2x - 2

Now add 2x to both sides, obtaining: 2x + 3y = -2 (in "standard form."

-4y-11x= 36

The Becks buy a plastic tarp to cover their firewood. A rectangle that is eight and one-third yards long and six and three-fourths yards wide. Part A Which equation models the best estimate for the area of the tarp?

Answers

Answer:

56 1/4 yards

Step-by-step explanation:

Area of the tarp = length × width

Length = 8 1/3 yards

Width = 6 3/4 yards

Area of the tarp = length × width

= 8 1/3 yards × 6 3/4 yards

= 25/3 × 27/4

= (25 * 27) / (3 * 4)

= 675 / 12

= 56 1/4 yards

Area of the tarp = 56 1/4 yards

He then took a random sample of 6 tests and calculated the minimum of the sample. He replaced those tests

Complete question is;

Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students’ nets is true? Both nets do not form octagonal prisms.

A) Only Alejandro’s net is correct.

B) Only Noya’s net is correct.

C) Neither net is correct.

D) Both nets are correct.

Answer:

C) Neither net is correct.

Step-by-step explanation:

From the second attached image, we can see what an octagonal prism looks like when it is opened to show all the faces.

However, looking at the first attached image showing the net drawings of boya and Alejandro, it is very clear that none of them got the required shape for the octagonal prism. Therefore, we can conclude that neither of the nets are correct.

The graph shown here is the graph of which of the following rational
functions
O A FO) = 2-3x+3
OB. AB) = x= 1962–31x-3
x-2
O C. FX) =

Answers

Given:

The graph of rational function.

To find:

The rational function.

Solution:

If the graph of a rational function has a vertical asymptote at [tex]x=a[/tex], then [tex](x-a)[/tex] must be a factor of the denominator of that rational function.

From the given graph it is clear that the graph has two vertical asymptotes. One is at [tex]x=-1[/tex] and another one is at [tex]x=3[/tex].

It means, [tex](x-3)[/tex] and [tex](x+1)[/tex] are the only two factors of the denominator of the rational function.

In option A, the factors of the denominator are different from [tex](x-3)[/tex] and [tex](x+1)[/tex] .

In option B, the denominator has an extra factor [tex]x-2[/tex].

In option C, the denominator has only two factors [tex](x-3)[/tex] and [tex](x+1)[/tex].

Therefore, the correct option is C.
