Answer:

D

Step-by-step explanation:

use the formula for point slope form, since all of your choices are in that form : y-y1=m(x-x1) (m is the slope)

we're given that m=2 and the point is (2,9)

Substitute into the equation

y-9=2(x-2)

That means that the answer is D

There are 28 nonfiction books and 35 fiction books in the teacher's collection. Which of the following expresses the ratio of no

Lostsunrise [7]

The answer is B) 4:5

First write the ratio out. To find the simplified expression, divide by the greatest common factor (GCF). In this case, the GCF of 28 and 35 is 7.

28:35
--- ----
7 7
=4:5

4:5 is the simplest form because you cannot simplify it further.

dalvyx [7]

Answer:

(a)|MA|, |MB| and |MC|

(b) |BD|

(c) |BC|

Step-by-step explanation:

An adapted diagram of this question is attached. You can vary the labelled letters as required.

<u>Definition</u>

A <u>radius </u>is a line drawn from the center of a circle to its circumference.
A <u>segment </u>is a line that connects two points.
A <u>diameter</u> is a chord which passes through the center of the circle.
A <u>chord</u> is any line joining two points on the circles' circumference.

By these definitions:

(a)Segments that are radii of this circle.

We have: |MA|, |MB| and |MC|

(b)Segment that is a diameter of this circle.

|BD|

(c)A chord of this circle that is not a diameter.

|BC|

Substitute the values for a, b, and c into b2 – 4ac to determine the discriminant. Which quadratic equations will have two real

adoni [48]

Step-by-step explanation

<h3>Prerequisites:</h3>

<u>You need to know: </u>

$b^2 - 4ac = 0 \Rightarrow 1 solution$

$b^2 - 4ac > 0 \Rightarrow 2 solutions$

$b^2 - 4ac < 0 \Rightarrow No\ real\ solutions$

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

$2x^2-7x-9 = 0$

$b^2 - 4ac$

$-7^2 - 4(2)(-9) = 121$

2 Solutions

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

$x^2-4x+4 = 0$

$b^2 - 4ac$

$-4^2 - 4(1)(4) = 0$

1 Solution

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

$4x^2-3x-1 = 0$

$b^2 - 4ac$

$-3^2 - 4(4)(-1) = 25$

2 Solutions

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

$x^2-2x-8 = 0$

$b^2 - 4ac$

$-2^2 - 4(1)(-8) = 36$

2 Solutions

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

$3x^2+5x+3 = 0$

$b^2 - 4ac$

$5^2 - 4(3)(3) = -11$

No Solutions
