Create Write a real-world problem that can be
solved using the equation 9 + 4x = 21 - 2x

Answers

Answer 1
1. you have to subtract 9 from both sides. 21-9= 12
2. you have to add 2x to both sides. 4x+2x= 6x
3. 6x divided by both sides =
4.x=2
Answer 2

The required real-world problem is below that can be solved using the equation.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

A construction company is building a new housing development and wants to know how many houses they need to build to reach a certain profit margin. They know that each house costs $9 to build and they want to sell each house for $21.

If they build x number of houses, the equation to calculate their profit is:

21x - (4x + 9) = profit.

To reach a certain profit margin, the company can set that equation equal to a specific value and solve for x.

equation 6x + 8y = 24. Determine the slope, y-intercept, and x-intercept and illustrate how you found each of these. Finally, explain what they represent in your word problem.

Answers

Answer:

slope is -6/8, y-int is 3, x-int is 4, this is found by setting the other variable to 0 and dividing -6 by 8 when you subtract 6x from the left side

Step-by-step explanation:

The slope is -3/4, y- intercept is 3 and x- intercept is 4.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Equation: 6x+ 8y= 24

As, the slope intercept form is

y = mx+ b

where m is the slope, b is the y- intercept.

Now, 6x+ 8y = 24

8y = 24- 6x

y = 24/8 - 6x/8

y = 3 - 3x /4

Thus, the slope is -3/4, y- intercept is 3.

Now, for x- intercept put y= 0

0 =3- 3x/4

3= 3x/4

x= 3 (4/3)

x= 4

Answers

Answer:

34

Step-by-step explanation:

9x-28 = 5x-8

4x = 20

x = 5

5 times x(aka 5) minus 8=17

9 times x(aka 5) minus 28=17

17+17

ywx=34

The value of the angle YWX will be 34.

What is geometry?

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that the two angles ZWY and ZWX are ( 9x - 28 ) and ( 5x - 8 ) respectively,

The angle will be calculated as:-

9x-28 = 5x-8

4x = 20

x = 5

The angle YWX will be the sum of the angles YWZ and XWZ.

YWX = ( 9 x 5) -28  + ( 5 x 5 ) - 8

YWX = 45 - 28 + 25 - 8

YWX = 17 + 17

YWX = 34

Hence, the measure of the angle YWX is 34.

The life of light bulbs is distributed normally. The variance of the lifetime is 900 and the mean lifetime of a bulb is 520 hours. Find the probability of a bulb lasting for at most 576 hours. Round your answer to four decimal places.

Answers

Answer:

0.969

Step-by-step explanation:

Given that:

Mean lifetime (m) = 520 hours

Variance = 900

Hence, standard deviation (s) = √900 = 30

Probability that bulb will last for at most 576 hours

X ≤ 576

Obtain the standardized score :

Using the relation :

Zscore = (x - m) / s

Zscore = (576 - 520) / 30

Zscore = 56 / 30

Zscore = 1.867

P(Z ≤ 1.867) : using the z probability calculator ;

P(Z ≤ 1.867) = 0.96905

Hence, P(Z ≤ 1.867) = 0.969

Why is this statement false?
If a number has 2 and 4 as factors, then it has 8 as a factor.

Answers

Answer:

It is false

Step-by-step explanation:

It is false because 12 has the factors of 2 and 4 but 8 is not a factor of 12.

The statement is false. If a number has 2 and 4 as factors, it doesn't mean that it has 8 as a factor.

The fact that a number has 2 and 4 as factors, doesn't mean that the number will have 8 as a factor. For example, 4 and 12 have both 2 and 4 as factors but don't have 8 as a factor

Factors of 4 = 1, 2 and 4.Factors of 12 = 1, 2, 3, 4, 6 and 12.

Therefore, the fact that a number has 2 and 4 as factors doesn't mean that it has 8 as a factor.
