Answer:

roots are not real

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 (a ≠ 0 )

Then the nature of the roots can be found using the discriminant

Δ = b² - 4ac

• If b² - 4ac > 0 then roots are real and distinct

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 then roots are not real

Given

9x² - 6x + 2 = 0

with a = 9, b = - 6, c = 2 , then

b² - 4ac = (- 6)² - (4× 9 × 2) = 36 - 72 = - 36

Since b² - 4ac < 0 then the roots are not real

Answer:

C

Step-by-step explanation:

On the left, we have 7 -Xs and 7 1s. So, the left can be represented by the expression:

[tex]-7x+7[/tex]

On the right, we have 5 (positive) Xs and 16 1s. So, the right can be represented by the expression:

[tex]5x+16[/tex]

They are equal to each other. So:

[tex]-7x+7=5x+16[/tex]

Solve for x. Add 7x to both sides:

[tex]7=12x+16[/tex]

Subtract 16 from both sides:

[tex]-9=12x[/tex]

Divide both sides by 12:

[tex]x=-9/12[/tex]

Reduce:

[tex]x=-3/4[/tex]

So, our answer is C.

Answer:

C

Step-by-step explanation:

the definition of an irrational number is an infinite decimal that has no repeating pattern. rational numbers can be converted into fractions.

A is incorrect because a whole number can be converted into a fraction.

      ex: 1 is also 3/3

B is incorrect because the definition of a rational number is that it can be converted into a fraction.

D is incorrect because a terminating decimal can be made into a fraction.

      ex: 4.5 is also 9/2

D)

A Irrational number is a decimal that terminates. I hope this helps! Please rate Brainiest!

Step-by-step explanation:

If two lines lie in the same plane and are perpendicular to the same line they are perpendicular is TRUE.

Two lines in the same plane that are equally spaced apart and never cross each other are said to be parallel lines.

Parallel lines are those lines in which slopes are the same and the distance between them remains constant.

If a line is perpendicular to another then they will make 90 degrees at the intersection.

So if another line is also making 90 degrees it means both lines must be in the same direction so they will be parallel as given in the image below.

Hence "If two lines lie in the same plane and are perpendicular to the same line they are perpendicular is TRUE".

How I would write my paragraph:

If angle 1 is congruent to angle 4, angle 1 must also be congruent to angle 3 by the transitive property. This is because is angle 3 and angle 4 are vertical angles, and they must be congruent. If angle 1 is congruent to angle 3, then the two lines in the middle must also be parallel due to the converse of the corresponding angles theorem. Because the two lines in the middle are parallel, angle 3 must be congruent to angle 2 by the alternate interior angles theorem.

Answer:

a) after 12.59 days the revenue will be equal

b) u just have to graph it

the second one is

a) the two solutions are x=4 and x=-4

b) x=-4 is not reasonable because time can’t be negative

c) after four seconds, the heights will be equal

Step-by-step explanation:

After 12.59 days the revenue for each game is the same. The two solutions of the system equation b(t) and p(t) are 4 and -4, and -4 is not a reasonable solution because time never be negative and after 4 seconds the rocket and the ball reach the same height.

1)

Given :

Math Game --   [tex]\rm M(d) = x^2-9x-10[/tex]

Reading Game --   R(d) = 2x + 10

It is given that after 'x' number of days the revenue for each game is the same, that is:

[tex]\rm x^2 -9x-10=2x+10[/tex]

[tex]\rm x^2 -11x-20=0[/tex]

Simplify the above quadratic equation.

[tex]\rm x = \dfrac{11\pm \sqrt{11^2-(4\times -20)} }{2}[/tex]

[tex]\rm x = \dfrac{11\pm \sqrt{201} }{2}[/tex]

x = 12.59 days

So, after 12.59 days the revenue for each game is the same.

The graph of both the revenue function is attached below.

2)

Given :

[tex]\rm b(t) =- t^2-2t+36[/tex]

p(t) = -2t + 20

The solution of this system can be determined by equating both the above function.

[tex]\rm -t^2 - 2t +36 = -2t +20[/tex]

Simplify the above equation.

[tex]\rm t^2 =16[/tex]

t = 4 and -4

a) The two solutions of the system are 4 and -4.

b) -4 is the solution is not a reasonable solution because time never be negative.

c) After 4 seconds the rocket and the ball reach the same height.

Answer:

im pretty sure its -9

Step-by-step explanation:

the equation explained would look something like this...

-5x-22=23

so you would isolate the variable by first adding 22 to both sides and the dividing by -5 on both sides

-5x-22=23
