20 pointsIn the figure below, which answer choice correctly identifies the name of two line segments?
A . B .C. D

Answer:

y = 3x - 20

Step-by-step explanation:

First, we have to find the slope of the equation. We can do by taking the opposite reciprocal of the slope of the original line.

The opposite reciprocal of-1/3 is 3/1 or 3.

So, the slope of our equation will be 3. Our equation so far is:

y = 3x + b.

To find b, or the y-intercept of the line, we can simply substitute the given coordinates into the equation. If we replace x with 6 and y with -2 and solve the equation, we can find the value of b.

-2 = 3(6) + b

-2 = 18 + b

-2 - 18 = b

b = -20

So the equation is,

y = 3x -20.

To check our equation, we can again substitute the coordinates into the equation and solve. If both sides are equal, then the equation is correct.

-2 = 6(3) - 20

-2 = 18 - 20

-2 = -2

The two lines are perpendicular if a 90° angle is formed when they

intersect.

The equation of the line that passes through point Z(6, -2) and is perpendicular to the line [tex]y = -\dfrac{1}{3} \cdot x + 2[/tex] is ; y = 3·x - 20

Reason:

The equation of the required line is, y = 3·x - 20

The given point is Z(6, -2)

Perpendicular to the line, [tex]y = -\dfrac{1}{3} \cdot x + 2[/tex]

Solution:

The slope of a line perpendicular to another line having a slope, m, is [tex]-\dfrac{1}{m}[/tex]

The slope of the given line is [tex]-\dfrac{1}{3}[/tex]

The slope of the perpendicular line is therefore;

[tex]m = -\dfrac{1}{\left(-\dfrac{1}{3}\right)} = \dfrac{3}{1} = 3[/tex]

The point and slope form of the equation of the given line is therefore;

y - (-2) = 3·(x - 6)

y + 2 = 3·x - 3×6 = 3·x - 18

y = 3·x - 18 - 2 = 3·x - 20

y = 3·x - 20

The equation of the line that passes through point Z(6, -2) and is perpendicular to the line [tex]y = -\dfrac{1}{3} \cdot x + 2[/tex] is therefore;

y = 3·x - 20

i guess 3 rd option is correct. ........hope it helps u ♥♥♥♥

Answer:

8

Step-by-step explanation:

if a = -b, then -a = b.

plug that into the (b = -c) problem, and you get -a = -c, or a = c

if a and c ar equal, then and b = -c, b also equals -a.

the problem then becomes a - b +c, where a = 8, c = 8, and b = -8

a = -b -> 8 = -(-8)

b = -c -> -8 = -(8)

a = c -> 8 = 8

Answer:

Step-by-step explanation:

AC = length of flagpole = 12 ft

AB = length of shadow = 14 ft

BC = length from the top of the flagpole to the end of the shadow = x ft

Use Pythagorean theorem to find the length of x,

x² = AC² + BC²

   = 12² + 14²

  = 144 + 196

  = 340

x = √340

x = 18.4 ft

Given -

x² + 4x + 1 = -3

To find -

the discriminant for the quadratic equation and to find how many real number solutions does the equation have. If it's discriminant = b² - 4ac

Concept applied -

As we know, Discriminant = b² - 4ac

A quadratic equation ax²+ bx + c = 0 has -

Solution -

Solving the quadratic equation to bring it in the form of ax² + bx + c = 0,

➛ x² + 4x + 1 = -3

➛ x² + 4x +3 + 1 = 0

➛ x² + 4x + 4 = 0

Here,

a = 1, b = 4 and c = 4.

Putting the values in the the formula, b²- 4ac = 0.

➙ (4)²- 4(1)(4)

➙ 16- 16

➙ 0

As, b²- 4ac = 0 hence the quadratic equation will have two equal roots (i.e., coincident roots).

Answer:

615.44 mm²

Step-by-step explanation:

Before finding the area of the circle, first, let us find the radius of the circle.

Given that,

diameter ⇒ 28 mm

Therefore,

28 = 2r

Divide both sides by 2.

14mm = radius

And now, let us find the area.

The formula to find the area of the circle is :

The expression for the area of the base is x² – 2x – 9. Therefore, the correct answer is (C) x² – 2x – 9.

To use synthetic division, we first need to set up the divisor in the correct form. Since we are looking for the expression for the area of the base of the rectangular prism, we know that the volume of the prism is given by:

volume = (area of base) × (height)

We are given that the height is x + 4, and the volume is x³ + 2x² – 17x – 36. Therefore, we can write:

x³ + 2x² – 17x – 36 = (area of base) × (x + 4)

Now we can use synthetic division to find the expression for the area of the base. The divisor is x + 4, so we write:

-4  | 1 2 -17 -36

    |   -4   8 36

    |-----------------

      1 -2 -9 0

The last number in the bottom row is 0, which means that x + 4 is a factor of the polynomial. The other numbers in the bottom row give us the coefficients of the quotient polynomial. Therefore, we can write:

x³ + 2x² – 17x – 36 = (x + 4)(x² – 2x – 9)

So the expression for the area of the base is x² – 2x – 9. Therefore, the correct answer is (C) x² – 2x – 9.

Step-by-step explanation:

because the sides 15, 25 are corresponding, sides 18, 30 are corresponding, 9 and x (unknown side) are corresponding.  here we discover that the ratio is 3:5 (15:25) and (18:30). so if the ratio of 9 to x is 3:5, the unknown side is 15.

Answer:

2:3 = 66%

Step-by-step explanation:

⇒ Convert the fraction 2/3 into decimal

⇒ 2/3 = 0.666

⇒ Multiply the decimal by 100: 0.66 × 100 = 66%

Therefore, the solution is 66%.

Answer:

3x - 4y + 8 = 0

Step-by-step explanation:

In figure,

When x = 0, y = 2

x = 4, y = 5

Two points on the line are (0, 2) & (4,5).

Slope = (5 - 2)/(4 - 0)= 3/4

Equation is:

=> y - 2 = (3/4)(x - 0)

=> y - 2 = 3x/4

=> 4y - 8 = 3x

=> 3x - 4y + 8 = 0

Check out the diagram below.

Since D and E are midpoints of AB and AC this means midsegment DE is parallel to side BC. Furthermore, it means DE is parallel to PQ because PQ is entirely on BC.

---------

Note how I drew a line from A to O. This forms two triangles ABO and ACO

For triangle ABO, segment DP is a midsegment because D and P are midpoints of AB and OB respectively. This means side DP is parallel to side AO. Keep this in mind as we'll use it later.

For triangle ACO, segment EQ is parallel to AO because EQ is a midsegment for similar reasons as already mentioned (E and Q are midpoints of AC and OC respectively). So this must mean that AO is parallel to EQ

Now chain the arguments together: if DP || AO and AO || EQ, then DP || EQ by the transitive property.

-----------

In short, we've proven two things

This is enough to conclude that DEQP is a parallelogram. By definition, a parallelogram has two pairs of opposite parallel sides.
