Solve: |x + 2|– 5 = -1

Answers

Answer 1

Answer:

x=−6

x=2

Step-by-step explanation:

Combine like terms and use the properties of equality to get the variable on one side of the equal sign and the numbers on the other side. Remember to follow the order of operations.

∣x+2∣−5=−1

Add 5 to both sides of the equation.

∣x+2∣=4

Use the definition of absolute value.

x+2=4

x+2=−4

Subtract 2 from both sides of the equation.

x=2

x=−6

Step-by-step explanation:

you're welcome :)

The equations of the line that passes throught the point given in the table are as follows;

[tex]y = -\frac{1}{6} x+\frac{1}{3}[/tex]

[tex]y-2=-\frac{1}{6}(x+10)[/tex]

Equation of a straight line

The linear equation of a striaght line is represented as follows:

y = mx + b

where

m = slopeb = y-intercept

Therefore,

m = 1 - 2 / -4 + 10

m = - 1 / 6

Let's find b using (-10, 2)

2 = - 1 / 6(-10) + b

2 = 5 / 3 + b

b = 2 - 5 / 3

b = 6 - 5 / 3

b = 1 / 3

hence,

[tex]y = -\frac{1}{6} x+\frac{1}{3}[/tex]

using y - y₁ = m(x - x₁)

y₁ = 2

x₁ = -10

m = - 1 / 6

Hence,

[tex]y-2=-\frac{1}{6}(x+10)[/tex]

A game involves drawing a single card from a standard deck. One receives 60 cents for an ace, 30 cents for a king, and 5 cents for a red card that is neither an ace nor a king. If the cost of each draw is 10 cents, what is the expected value?

Answers

Answer:

The expected game value is -1 cent

Step-by-step explanation:

Here, we want to calculate the expected value of the game

We have 4 aces and 4 kings, including 26 red cards

The number of aces is 4

Probability of drawing an ace is 4/52 = 1/13

Probability of drawing a king is also 4/52 = 1/13

There are 26 red cards

The number of red cards that are neither ace nor king

There are 2 red aces and 2 red kings

So the number of cards that are red but are not

aces nor kings are 26-2-2 = 22

The probability of selecting this is 22/52 = 11/26

So the expected value is simply the probability multiplied by the amount

Thus, we have;

(60 * 1/13) + (30 * 1/13) + (5 * 11/26)

= 60/13 + 30/13 + 55/26

= (120 + 60 + 55)/26 = 9.038 cents which is approximately 9 cents

we subtract this from the 10 cents we are playing with, thus we are left with 9-10 = -1 cent

-3y + 2x - 4

Step-by-step explanation:

Answer:

-3y - 4 + 2x

Step-by-step explanation:

when it says combine like terms, it means combine the terms that have the same variable

-7y, -2y, and 6y all have the same variable: y

so when you combine them, you get -3y (notice that the variable doesn't change, only the number in front of it does)

-2 and -2 are like terms, they don't have a variable

when you combine them, you get -4

-4x and 6x are like terms, their common variable is x

when you combine these, you get 2x

now put your answers together to get -3y - 4 + 2x

An element with a mass of 650 grams decays by 13.2% per minute. To the nearest minute, how long will it be until there are 220 grams of the element remaining?

Answers

Answer: 8

Step-by-step explanation:

The time taken where there is 220 grams of the element remaining should be considered as the 5 minutes.

Calculation of the time taken:

Since An element with a mass of 650 grams decays by 13.2% per minute. and there is 220 grams of the element remaining.

So, the mass decays be

= 650 - 220

= 430

Now the total percentage be like

[tex]= 430 \div 650[/tex]

= 66.15%

Now the time taken should be

= [tex]66.15\div 13.2[/tex]

= 5 minutes

The time taken where there is 220 grams of the element remaining should be considered as the 5 minutes.

Answer:

x = 3

Step-by-step explanation:

We need it in factorized form to get x.

If the quadratic equation can be divided by a-2 the first part is:

(a-2)

Now to get a², the a must be multpilied by itself. So

(a-2)(a)

To get -10, -2 must be multiplied by 5. So:

(a-2)(a+5)

we can expand to get x

a² + 5a - 2a -10

a² + 3a - 10

a² + ax - 10

i THINK it’s D cuz the other side would also be 65 and it’s a 180 line in total

The measure of x is 115° from the given parallel lines. Therefore, option D is the correct answer.

What are angles of parallel lines?

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

Let the interior alternate angle to 65° be y.

Now, y=65° (Alternate interior angles are equal)

Here, y°+x°=180° (Adjacent angles)

65°+x°=180°

x°=115°

Therefore, option D is the correct answer.
