Answer:

a= -6

Step-by-step explanation:

Given

a=2+3a+10

In order to find the value of a, we have to isolate a on a single side of the equation

So,

subtracting 3a from both sides

a-3a = 2+10+3a-3a

=>a-3a=12

=> -2a = 12

Dividing both sides by -2

=> -2a/-2 = 12/-2

=> a = -6

The value of a in the given equation is -6 ..

Answer:

Step-by-step explanation:

(1) y = 4x + 5 and (2) y = 4x - 5

substitute (1) to (2):

4x + 5 = 4x - 5         subtract 4x from both sides

5 = -5      FALSE (no solution)

(1) y = 4x + 5 and (2) 2y = 8x + 10

substitute (1) to (2):

2(4x + 5) = 8x + 10          divide both sides by 2

4x + 5 = 4x + 5         subtract 4x from both sides

5 = 5   TRUE (infinitely many solutions)

(1) y = 4x + 5 and (2) y = x + 5

substitute (1) to (2):

4x + 5 = x + 5         subtract 5 from both sides

4x = x          subtract x from both sides

3x = 0         divide both sides by 3

x = 0

Put it to (2):

y = 0 + 5 = 5

One solution (0, 5)

(1) y = 4x + 5 and (2) y = 8x + 10

substitute (1) to (2):

4x + 5 = 8x + 10       subtract 5 from both sides

4x = 8x + 5       subtract 8x from both sides

-4x = 5           divide both sides by (-4)

x = -1.25

Put it to (1):

y = 4(-1.25) + 5 = -5 + 5 = 0

One solution (-1.25, 0)

Answer:   [tex]\bold{\dfrac{1}{19}}[/tex]

Step-by-step explanation:

Let x represent the quantity of yellow cubes

Yellow: x

Blue: three times yellow --> 3x

Green: five times blue --> 5(3x) = 15x

Yellow + Blue + Green = Total cubes

    x      +   3x  +    15x   =       19x

[tex]Probability=\dfrac{yellow}{total}=\dfrac{x}{19x}=\large\boxed{\dfrac{1}{19}}[/tex]

The probability of Sarah taking out a yellow cube from the bag is 0.7 or 5/7.

The fraction of favorable outcomes of an event to the total number of outcomes of the event is said to be the probability. The fraction can also be written in the simplest form.

P(E)= n(E)/n(S) where E -event, n(E) - favorable outcomes and n(S) is the total outcomes.

It is given that a bag contains blue cubes, yellow cubes, and green cubes.

Consider the number of blue cubes = n

So, the number of yellow cubes = 3 times as many as blue cubes

                                                     = 3n

Then, 5 times as many as green cubes = blue cubes

⇒ number of green cubes = n/5

Then the total number of cubes in the bag

= n + 3n + n/5

⇒ [5n + 15n + n]/5

⇒ 21n/5

Then the probability of taking out a yellow cube = (possible outcomes of a yellow cube)/(total number of cubes)

⇒ [tex]\frac{(3n)}{(21n/5)}[/tex]

⇒ 15n/21n

⇒ 5/7

∴ The probability of taking out a yellow cube = 5/7 = 0.7.

Answer:

The correct answer is last option  

10

Step-by-step explanation:

Points to remember

Distance formula

Length of a line segment with end points (x1, y1) and (x2, y2) is given by,

Distance = √[(x2 - x1)² + (y2 - y1)²]

To find the distance between given points

Here  (x1, y1) = R(0, 0)  and (x2, y2)  = S(6, 8)

Distance, RS = √[(x2 - x1)² + (y2 - y1)²]

 = √[(6 - 0)² + (8 - 0)²]

 = √[6² + 8²]

 = √[36 + 64]

In some cases you would have to subtract in order to get the specified angle. That is when the angle given is positive.

b) This time we want to find an that coterminal with [tex]\frac{15\pi}{4}[/tex] radians.

We keep subtracting multiples of [tex]2\pi[/tex] until we get an angle measure within the specified range.

[tex]\frac{15\pi}{4}=\frac{15\pi}{4}-2\pi=\frac{7\pi}{4}[/tex]

Answer:

B) Bisector of an angle  ~apex

Step-by-step explanation:

Option B is correct, bisector of an angle is defined as the set of all points in a plane that are equidistant from the two sides of a given angle.

A system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

The bisector of an angle is a straight line or a line segment that divides an angle into two equal angles.

In other words, the bisector of an angle is the set of all points in a plane that are equidistant from the two sides of a given angle.

The geometric object defined as the set of all points in a plane that are equidistant from the two sides of a given angle is the Bisector of an angle.

Hence, bisector of an angle is defined as the set of all points in a plane that are equidistant from the two sides of a given angle.

Answer:

f(4) = 4

Step-by-step explanation:

F(x)=1/4•2^x

Let x = 4

F(4)=1/4•2^4

      = 1/4 * 2^4

      = 1/4 *16

      = 4

Answer: f(4) = 4

Step-by-step explanation:

f(x) = 1/4 . 2^x

To find f(4) we simply replace x by 4 in the above equation;

f(4) =1/4 . 2^4

f(4) = 1/4 . 16

f(4) = 16/4

f(4) = 4

Therefore f(4) is equal to 4

Answer:

15+25d=t

Step-by-step explanation:

the initial value is 15 it increases(+) by 25 to each kilometer(distance=d) of depth.

The equation that models the relationship between distance d in kilometers and temperature t in degrees Celsius is t = 25d + 15. This means that for each kilometer increase in depth, the temperature increases by 25 degrees Celsius in addition to the initial 15 degrees Celsius surface temperature.

The relationship between the variables, distance (d) and temperature (t), is described as a linear function. Given that the surface temperature is 15 degrees Celsius and it increases by 25 degrees Celsius with every kilometer, the mathematical model is expressed as:

t = 25d + 15

In this equation, t represents the temperature and d is the distance from the surface in kilometers. This implies that for every kilometer increase in depth, the temperature increases by 25 degrees Celsius on top of the initial 15 degrees Celsius surface temperature.

Step-by-step explanation:

Answer:

To test whether or not a number is divisible by 4 is to check to see if the number that’s made from the final two digits of the original number is itself divisible by 4. If it is, then the entire number is divisible by 4 too.

First you must distribute the numbers outside the parentheses to the numbers inside the parentheses

Let's start with the first one:

9(x-2) + 3(5-2x) = 2

9(x - 2)  

9*x + 9*-2

9x + (-18)

9x - 18

so...

9x - 18 +  3(5-2x) = 2

Now on to the second set of parentheses:

9x - 18 + 3(5-2x) = 2

3(5 - 2x)

3*5 + 3*-2x

15 + (-6x)

15 - 6x

so...

9x - 18 + 15 - 6x = 2

Now you must combine like terms. This means the numbers with the same variables must be combined...

First set of like terms:

9x - 18 + 15 - 6x = 2

9x + (-6x)

3x

so...

3x - 18 + 15 = 2

Second set of like terms:

3x - 18 + 15 = 2

-18 + 15

-3

so...

3x - 3 = 2

Now bring -3 to the right side by adding 3 to both sides (what you do on one side you must do to the other). Since -3 is being negative on the left side, addition (the opposite of negative/subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.

3x + (- 3 + 3) = 2 + 3

3x + 0 =5

3x = 5

Next divide 3 to both sides to finish isolating x. Since 3 is being multiplied by x, division (the opposite of multiplication) will cancel 3 out (in this case it will make 3 one) from the left side and bring it over to the right side.

3x/3 = 5/3

x = [tex]\frac{5}{3}[/tex]

The answers to your three problem question are shown

1) the value of p is

p = -1

2) The coordinates of the focus are

Focus =  (-1,0)

3) The equation of the directrix is

Directrix

x = 1

Step-by-step explanation:

The general equation for this parabola is

y^2 = 4px

Problem 1

Find the value of p.

We are told that the equation of the problem is

y^2 = -4x

And the general formula is

y^2 = 4px

From there, we can deduce that

p = -1, because

y^2 = 4(-1)x = -4x

This means that p = -1

Problem 2

Find the focus

To find the focus we can see the equations attached below for the focus, vertex and directrix.

In these case, the equations still apply, even though the variable is inverted, we just need to adjust it

y^2 = -4x =>

x = (-1/4)*y^2

x = a*y^2 + b*y +c

Focus

((4ac -b^2  + 1)/4a, -b/2a)

But, b = 0 and c = 0

=>

(1/4a,0) = (1/4(-1/4),0) = (-1,0)

Focus =  (-1,0)

Problem 3

Find the directrix

The equation is

x = c - (b^2 + 1).4a

But, b = 0 and c = 0

x = -4*a

x = -4* (-1/4) = 1

x = 1

Directrix

x = 1

Answer: P is -1

Focus is (-1,0)

Directrix is X= 1

[tex]6y ^ 6[/tex]

Answer: It is!!!!!!!!

Answer:

The correct option is C.

Step-by-step explanation:

The standard form of a parabola is

[tex]y=ax^2+bx+c[/tex]

The table of values represents the coordinate pairs of the parabola. It means the graph of the parabola must be passes through these coordinate pairs.

From the given table it is clear that the parabola passes through the points (0.5,21), (1,34) and (1.5,39).

[tex]21=a(0.5)^2+b(0.5)+c[/tex]

[tex]21=0.25a+0.5b+c[/tex]             .... (1)

[tex]34=a(1)^2+b(1)+c[/tex]

[tex]34=a+b+c[/tex]                      .... (2)

[tex]39=x(1.5)^2+y(1.5)+z[/tex]

[tex]39=2.15a+1.5b+c[/tex]            .... (3)

On solving (1), (2) and (3), we get

[tex]a=-16, b=50,c=0[/tex]

The equation of parabola is

[tex]y=-16x^2+50x+0[/tex]

[tex]y=-16x^2+50x[/tex]

The graph of parabola is shown below. It is same as graph in option C.

Therefore the correct option is C.

Answer:

x²+y²=16

Step-by-step explanation:

the general equation for a circle is given as :

(x−h)²+(y−k)²=r²

where (h, k) is the coordinate of the center of the circle and r is the radius

in this case h=0, k=0 and r = 4

equation becomes

x²+y²=4²

or

x²+y²=16

Answer: Last option.

Step-by-step explanation:

The equation of a circle in Center-radius form is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where the center is at the point (h,k) and "r" is the radius.

If the center of this circle is at the origin, means that:

[tex]h=0\\k=0[/tex]

Since the radius is 4, then:

[tex]r=4[/tex]

Now we need to substitute these values into the equation of the circle.

[tex](x-0)^2+(y-0)^2=(4)^2[/tex]

Simplifying the equation, we get:

[tex]x^2+y^2=16[/tex]

This matches with the last option.
