Solve the equation using square roots.

[tex]4x^{2} +9=0[/tex]

Answer:

2

Step-by-step explanation:

We can find the slope by

m = (y2-y1)/(x2-x1)

    = (4-2)/(-1 - -2)

    = (4-2)/( -1 +2)

    =2/1

   = 2

Answer:

2

Step-by-step explanation:

slope= [tex] \frac{y1 - y2}{x1 - x2} [/tex]

Thus, slope of the line

[tex] = \frac{4 - 2}{ - 1 - ( - 2)} \\ = \frac{2}{2 - 1} \\ = \frac{2}{1} \\ = 2[/tex]

Answer:

5 units

Step-by-step explanation:

I used the pythagorean theorem (a^2 + b^2 = c^2) to find the answer. I put 3 in a and 4 in b. I squared them and got 9 + 16 = 25. I found the square root of 25 which is 5 and that is my answer.

The correct answer would be option #2!

The following best describes the motion of the car shown is,

⇒ It travels for 3 hours, then stops for 1 hour, and finally travels again for 1 hour.

The correct option is (B).

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Now, From 0-4 the graph is uniformly increasing which represents 3 hours that's it's moving.

Then from 2-3 there no increment or decrement which represents it is in rest.

Then, from 4 - 5 the graph is uniformly increasing again which represents 1 more hours it is moving.

Hence, We get;

⇒ It travels for 3 hours, then stops for 1 hour, and finally travels again for 1 hour.

Answer:

To find the scale factor, we simply create a ratio of the lengths of two corresponding sides of two polygons. If the ratio is the same for all corresponding sides, then this is called the scale factor and the polygons are similar.

Answer: you are right

Step-by-step explanation:

Answer:

You are correct

Answer:

Please check the attached picture

Step-by-step explanation:

In the first row, there are 5 players in total, 4 of them practice extra time, then 5 - 4 = 1 player does not practice extra time.

In the second row, there are 5 players in total, 2 of them practice extra time, then 5 - 2 = 3 players do not practice extra time.

In the third row, there are 8 players in total, 2 of them practice extra time, then 8 - 2 = 6 players do not practice extra time.

We finally add up each column, to complete the table.

I hope this helps!

Answer:

56 cubic inches

Step-by-step explanation:

Volume of cube box = 6^3 = 6 *6*6 = 216 , Volume of rectangular box = 10*4*4 = 160 . Difference = 216 - 160 = 56 cubic inches. 56 cubic inches greater is the volume of the cube-shaped box than the rectangular box.

Answer:

Step-by-step explanation:

cube volume=side^3

given that the side is 6, the volume is 6^3 or 216 cubic inches

volume regular rectangular prism=length times width times height

given that length=10, width is 4 and height is 4, volume=10*4*4=160 cubic inches

how much greater

216-160=56

it is 56 cubic inches greater

Answer:

The question is asking to choose among the following choices that states the equation that is not necessarily true about the said coordinate plane and in my further calculation, the answer would be G'H' = 8 units.

( I think you made a mistake when writing the answer choice for B, because the correct answer is G'H' = 8 units )

Anyways, Hope this helps!

126 in^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2) h

A = 1/2 ( 12+16)*9

A = 1/2 (28) *9

  = 126

Answer:

126 ^2 in

(12)+(16)/2 * (9)

Area= a+b/s(h)

Answer:

y = 2x - 18

Step-by-step explanation:

There are lots of different methods to do these types of questions, but this is the way i like to do it.

Coordinate (x1, y1) : (4, -10) and Gradient (m): 2

Start with this generic equation:

y- y1 = m(x-x1)

Substitute in the values they have given you:

y - (-10) = 2(x-4)

This becomes:

y + 10 = 2x - 8

Keep solving by moving the 10 over to the other side:

y = 2x -8-10

y = 2x - 18

An easy way to double check:

1) the coefficient of x is the slope. We got 2x, and the slope is 2, so that's correct.

2) Substitute x=4 into the equation, and we get -10, which is the exact coordinate that they gave us. This is also right.

Hope this helped : )

Answer:

$300

Step-by-step explanation:

10% = .1 and each TV costs 120 so .1*120=12 then you take 12*25 since 12 is the money he makes for seeling the tv multiplied by the total TV's sold and you get 300 so Mike makes $300

Answer:

300 just cross multiply to get the answer.

Step-by-step explanation:

Total marbles = 2 + 4 +1 + 8 = 15 marbles

Probability of blue marble = 4 / 15

Probability of green marble = 2 / 15

Answer:

4/105

Step-by-step explanation:

Total number of marbles: 2 + 4 + 1 + 8 = 15

Number of blue marbles: 4

First drawing:

p(blue marble) = 4/15

Now there are 14 marbles left.

Number of green marbles: 2

p(green marble) = 2/14 = 1/7

p(blue then green) = p(blue) * p(green) = 4/15 * 1/7 = 4/105

Answer: 4/105

Answer:

  5.  A) two solutions

  6.   one solution

Step-by-step explanation:

5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:

  b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number

When the discriminant is positive, there are two real solutions.

6. The equation factors as ...

  0 = 3(x +3)^2

This will have one real solution at x=-3.

Answer: 10,488 cu. in.

Step-by-step explanation:

Volume of rectangular prism = l x w x h

= 16 x 18 x 23 = 6624 cu. in

Volumr of triangular prism = 1/2bh (height of prism)

= 1/2 x 23 x 21 x 16

= 3864 cu. in.

Volume of the figure = 6624 + 3864 = 10,488 cu. in

3.5/v^2

Step-by-step explanation:

-21v^6/-6v^8

-21/-6=3.5

v^6-v^8=-2

since -2 cannot be expressed as v^-2 it must be expressed as 1/v^2

so 3.5/v^2 is your answer

Answer:

AM = 26

Step-by-step explanation:

AM = MC

x+20 = 5x-4

Subtract x from each side

x+20-x = 5x-x-4

20 = 4x-4

Add 4 to each side

20+4 = 4x-4+4

24 = 4x

Divide by 4

24/4 = 4x/4

6 =x

We want AM

AM = x+20

       =6+20

      =26

Answer:

26

Step-by-step explanation:

x+20=5x-4

x+24=5x

24=4x

x=6

x+20

substitute 6 for x

6+20

70°

Step-by-step explanation:

By inscribed angle theorem:

[tex] 95° = \frac{1}{2}(c + 120°)\\\\

\therefore 95°\times 2 = c + 120°\\\\

\therefore 190° = c + 120°\\\\
