Find the value of x.

D
(Round to the nearest tenth as needed.)

Answer:

x = ± 6

Step-by-step explanation:

To solve the equation let y = 0 , that is

0 = 36 - x² ( add x² to both sides )

x² = 36 ( take square root of both sides )

x = ± [tex]\sqrt{36}[/tex] = ± 6

That is x = - 6 or x = 6

Answer:

77%, yes pass, at least 16

Step-by-step explanation:

so 17/22 is 0.77, convert to percentage is 77%

77% is above 70% so you passed

if you guess and check, 15/22 is 68%. since thats just a bit lower than 70%, u need at least 16 questions to pass

yw in advance :))

Answer:

a) 77%   b) Yes   c) 16

Step-by-step explanation:

17 out of 22 questions correct is set up as

17/22= .7727

round this number down and take it from decimal form to percentage.

.77 x 100 = 77%

You scored a 77% and you did score enough to pass.

The minimum number correct to still be able to pass is 16.

16/22 = .7273 = 73%

Answer:

  left-to-right

Step-by-step explanation:

[There's a lot to read here. If you read it, maybe you'll have a better understanding.]

This is asking you the first step required to solve each of the equations.

The general process of solving an equation involves performing operations that result in the variable of interest being on one side of the equal sign (by itself), and everything else being on the other side. When variable and constant terms are mixed, we generally want to remove the variable term.

The underlying rule for all of this is "whatever is done to one side of the equation must also be done to the other side." The exceptions are simplification and substitution.

"Inverse" operations are of use in this process. That is why you are taught about the "additive inverse" (negative) of a number, and the "multiplicative inverse" (reciprocal) of a number. Adding the additive inverse results in the additive identity element (0). Similarly, multiplying by the multiplicative inverse results in the multiplicative identity element (1). Adding 0 or multiplying by 1 leaves only the original value.

__

With this in mind, we can look at the given equations to see what is needed to solve them.

2 +2y = y

  We see that the left side of the equation has both a constant term and a variable term. To remove the variable term we add its additive inverse: (-2y). Adding a negative value is the same as subtracting a positive value. That is, we can describe what we want to do as "subtract 2y from both sides".

When we do that, the result is ...

  2 +2y -2y = y -2y . . . . . here, we show the subtraction

  2 = -y . . . . . . . . . . . . . and this is the result of simplifying that.

Notice the y term is now on one side of the equal sign and the constant is on the other side. We are one step closer to the solution, which is the whole point.

__

5(y -4) = 2y

  This equation has parentheses. It often works well as a first step to eliminate the parentheses, generally using the distributive property. That is, we "distribute 5".

When we do that, the result is ...

  5(y) -5(4) = 2y . . . . . . . . here, we show the distribution

  5y -20 = 2y . . . . . . . and this is the result of simplifying that

This puts us one step closer to the solution, which is the whole point.

__

5y = 10 -2y

Here, the unwanted variable term is -2y on the right side of the equation. To remove it, we add 2y to both sides.

When we do that, the result is ...

  5y +2y = 10 -2y +2y . . . . . . . showing the addition of 2y

  7y = 10 . . . . . . . . . . . . . . . simplified

This puts us one step closer to the solution.

__

5 = 25y

This equation has the variable term and the constant term already separated. However, there is a coefficient on the variable term that is not equal to 1. We want to make that coefficient be 1. To do that, we multiply it by its multiplicative inverse: 1/25. That is, we divide both sides by 25.

When we do that, the result is ...

  5/25 = 25y/25 . . . . . . showing division by 25

  1/5 = y . . . . . . . . . simplified (and the fraction reduced)

This gives us the solution. There are no more steps required.

Answer:

it’s m= -1/4

Step-by-step explanation:

it’s the slope

The slope of the line is 4.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.2The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

A line is perpendicular to the line y = 4x - 3.

y = 4x - 3 is in the form of y = mx + c

So,

m = 4.

Now,

The line has a y-intercept at (0,-2).

So,

c = -2

Now,

The equation of a line is given by:

y = mx + c

y = 4x - 2

Thus,

Slope is 4.

Step-by-step explanation:

Answer:

18 and 6

Step-by-step explanation:

The sum of two numbers is twice their difference: 18 + 6 = 24, 18 - 6 = 12. 24 is twice of 12.

The larger number is 5 more than twice the smaller. Twice of 6 is 12. 5 more than 12 is 18.

Step-by-step explanation:

the most common form of line equation is

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-intercept (the y value when x = 0).

once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and since for b.

for slope a :

x changes by -6 (from 4 to -2)

y changes by +36 (from -31 to 5)

so, the slope is +36/-6 = -6

and the equation looks now like this

y = -6x + b

let's use the second point

5 = -6×-2 + b = 12 + b

-7 = b

the full equation is

y = -6x - 7

Answer: 2/5

Step-by-step explanation: 2/5 is the answer bozo

The probability that the 2 boys are seated next to each other will be P(A) = 0.16.

Given is that in a movie theater, 2 boys and 3 girls are randomly seated together in a row.

The total number of ways in which all of them can be seated are -

n{S} = (2 + 3) x (2 + 3) = 5 x 5 = 25

n{S} = 25

The total number of ways in which two boys can be seated together are -

n{A} = 4

So, the probability that the 2 boys are seated next to each other will be -

P(A) = n(A)/n(S)

P(A) = 4/25

P(A) = 0.16

Therefore, the probability that the 2 boys are seated next to each other will be P(A) = 0.16.
