2x+3y=12
if y=8
what is x

Answers

Answer 1

Answer:

-6

Step-by-step explanation:

2x + 3(8) = 12

2x + 24 = 12

2x = 12 - 24

2x = -12

x = -12/2

x = -6

2x+3y=12if Y=8what Is X
Answer 2
X=-6

2x+3y=12
2x+3(8)=12
2x+24=12

Jerome went to the store and bought 2 cartons of eggs for $1.30 each and 1 box of pancake mix. His total bill was $6.10. Which equation can be used to correctly find the cost, x, of the box of pancake mix?

Answers

1.30(2) + X = 6.10
This would be one of a few equations to do. 1.30(2) represents the cartons of eggs which are each 1.30. the X will represent the price of pancake mix and the total is 6.10.
6.10-2(1.30) can be used the correctly find the cost, x, of the box of pancake mix.

how can you
change the equation y = mx + b to
shift the graph down?

Answers

Step-by-step explanation: To shift the graphs up and down on the coordinate system, you need to manipulate or change the y-intercepts.

The y-intercept is just the constant term in the equation.

As long as the slopes remain the same, the graphs can be

translated up or down by changing the constant value.

Take a look at these lines graphed below.

Notice that y = x + 11 is the same as y = x + 4 but

y = x + 11 is translated 7 units down to get y = x + 4.

Seventy-five percent of the light aircraft that disappear while in flight in a certain country are subsequently discovered. Of the aircraft that are discovered, 70% have an emergency locator, whereas 89% of the aircraft not discovered do not have such a locator. Suppose a light aircraft has disappeared. (Round your answers to three decimal places.) (a) If it has an emergency locator, what is the probability that it will not be discovered

Answers

Answer:

0.05 = 5% probability that it will not be discovered

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Has an emergency locator

Event B: Not discovered

Probability of having an emergency locator:

70% of 75%(discovered).

100 - 89 = 11% of 100 - 75 = 25%(not discovered). So

[tex]P(A) = 0.7*0.75 + 0.11*0.25 = 0.5525[/tex]

Intersection of events A and B

Having an emergency locator and not discovered, so 11% of 25%

[tex]P(A \cap B) = 0.11*0.25 = 0.0275[/tex]

What is the probability that it will not be discovered?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0275}{0.5525} = 0.05[/tex]

0.05 = 5% probability that it will not be discovered

Which integer represents this scenario?


an elevator goes down 2 floors

Answers

Answer:

We usually define the cases like this as follows:

If we go upwards N units, then we add N.

If we go downwards N units, then we subtract N.

In this case, suppose that the elevator is originally on the floor K (can be any integer number larger or equal than 2)

Then the elevator goes down 2 floors.

Then now the elevator will be on the floor (K - 2)

Then the integer that represents this scenario is -2, which represents the change in the floor number where the elevator is.

One number is 24 more than the other. What are the numbers if their sum is 84

Answers

Answer:

The required numbers are 30 and 54.

Step-by-step explanation:

Let 'x' be the smaller numberLet 'y' be the larger number

Given that one number is 24 more than the other, so

[tex]y = x + 24[/tex]

Given that the sum of the numbers is 84, so

[tex]x + y = 84[/tex]

so we have two equations

[tex]\begin{bmatrix}y=x+24\\ x+y=84\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y-x=24\\ y+x=84\end{bmatrix}[/tex]

subtracting the equartions

[tex]y+x=84[/tex]

[tex]-[/tex]

[tex]\underline{y-x=24}[/tex]

[tex]2x=60[/tex]

now solve 2x = 60 for x

[tex]2x=60[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{60}{2}[/tex]

Simplify

[tex]x=30[/tex]

For y - x = 24 plug in x = 30

[tex]y-30=24[/tex]

Add 30 to both sides

[tex]y-30+30=24+30[/tex]

Simplify

[tex]y=54[/tex]

Thus, the required numbers are 30 and 54.

Verification:

Given that one number is 24 more than the other, so

[tex]y = x + 24[/tex]

substitute x = 30

y = 30 + 24

y = 54

Thus, y is 24 more than x.

Given that the sum of the numbers is 84, so

[tex]x + y = 84[/tex]

sustitute x = 30 and y = 54

30 + 54 = 84

84 = 84

L.H.S = R.H.S

Thus,  the sum of the numbers is indeed 84.

Huy is solving a quadratic equation by completing the square. His first few steps​ (steps 1-4) are shown below. Which of the following statements is true regarding​ Huy's work?

Solution x2+3x=5 step 1
x2+3x+9=5+9 step 2
(x+3)2=14 step 3
x=−3±14−−√ step 4(1 point)

Huy is incorrect. He made a mistake in step 1 when he added a 5 to both sides. He should have only added a 5 to the left side of the equation.

Huy is incorrect. He made a mistake in step 4 when he solved the equation (x+3)2=14 for x.

Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.

Huy is correct. He has done a nice job of completing the square.

The true statement will be;

''Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.''

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The quadratic equation is,

⇒ x² + 3x - 5 = 0

Now,

Huy is solving a quadratic equation by completing the square.

The steps are;

The quadratic equation is,

⇒ x² + 3x - 5 = 0

Solution; x²+3x=5   (step 1)

x²+3x+9 = 5+9        (step 2)

(x + 3)² = 14             (step 3)

x = - 3 ± √14           (step 4)

Clearly, In step 2 when add 9 then it not make the square form.

That is,

x² + 3x + 9 ≠ (x + 3)²

Thus, The true statement will be;

''Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.''
