is it always,sometimes,or never true that an equation in slope-intercept from represents a direct variation?Spport your answer with examples.

Answers

When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation.

In simpler terms, that means if A is always twice as much as B, then they directly vary. If a gallon of milk costs $3, and I buy 1 gallon, the total cost is $3. If I buy 10 gallons, the price is $30. In this example the total cost of milk and the number of gallons purchased are subject to direct variation -- the ratio of the cost to the number of gallons is always 3.

To be more "geometrical" about it, if y varies directly as x, then the graph of all points that describe this relationship is a line going through the origin (0, 0) whose slope is called the constant of variation. That's because each of the variables is a constant multiple of the other.Hope I helped

Final answer:

An equation in the slope-intercept form represents a direct variation only when the y-intercept is zero. For instance, y=3x is a direct variation while y=3x+9 isn't due to having y-intercept 9. The differentiation between a direct variation and a simple linear equation helps understand the relationship in algebra.

Explanation:

In mathematics, the slope-intercept form of an equation can represent a direct variation, but it's only sometimes true. An equation in the slope-intercept form represents a direct variation only when the y-intercept (the 'b' in the equation y=mx+b) is zero.

For example, the equation y = 3x represents a direct variation because the y-intercept is 0. Here, the value of y changes proportionately with x, which denotes a direct variation. However, in the equation y=3x+9 (represented in Figure A1), it does not represent a direct variation since the y-intercept is 9 (b ≠0).

Therefore, the direct variation depends on whether the y-intercept is zero or not in a slope-intercept equation. This relationship between the x and y variables in algebra helps scholars understand the difference between a direct variation and a simple linear equation.

Sandy works at a clothing store. She makes $7 per hour plus earns 15% commission on her sales. She worked 74 hours over the last two weeks and had a total of $1,678 in sales before taxes. 

Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?

Answers

15% of $7 is $1.05
7 x 74 = 518
1678 + 518 = 2196

She will earn $2196 in those 2 weeks

Sandy's total earnings before taxes for the two weeks will be $769.70, which includes $518 from her hourly wages and $251.70 from her sales commission.

To solve how much Sandy will earn in hourly wages and commission over two weeks of work at a clothing store, where she makes $7 per hour and earns a 15% commission on her sales of $1,678, we first calculate her hourly wages: Sandy worked 74 hours, and at $7 per hour, her earnings from hours worked are 74 hours x $7/hour = $518.

Next, we calculate her commission earnings: 15% of $1,678 in sales is 0.15 x $1,678 = $251.70.

Adding both earnings gives us Sandy's total earnings before taxes, which is $518 + $251.70 = $769.70.

I have 4 times as many hats as my brother. Together we have 50 hats. How many hats do we each have?

Answers

x = ur hats, y = ur brothers hats
x + y = 50
x = 4y

4y + y = 50
5y = 50
y = 50/5
y = 10 <== ur brother has 10 hats

x + y = 50
x + 10 = 50
x = 50 - 10
x = 40 <== u have 40 hats
x=your number of hats
y=number of hats bro has

x is 4 times y
x=4y
together (x+y) it is 50

x+y=50
since x=4y, replace x with fy
4y+y=50
5y=50
divide both sides by 5
y=10
x=4y
x=4(10)
x=40

you have 40 and bro has 10

To make 1 1/2 dozen muffins, a recipe uses 3 1/2 cups of flour. How many cups of flour are needed for every dozen muffins made? Enter your answer in the box as a mixed number in simplest form.

Answers

i hope this helps you

The number of cups of flour required to make 1 dozen muffin is 2 1/3 cups.

To find out how many cups of flour are needed for every dozen muffins made, we'll use the information given that 3 1/2 cups of flour make 1 1/2 dozen muffins. We need to set up a proportion to scale the amount of flour down to the amount needed for 1 dozen muffins. First, we know that 1 1/2 dozens equals 18 muffins (since a dozen is 12), so we can express the known ratio as:

3 1/2 cups of flour / 18 muffins

To find out how many cups of flour make 12 muffins, we set up the proportion:

(3 1/2 cups / 18 muffins) = (x cups / 12 muffins)

We then cross-multiply and solve for x, which represents the cups of flour:

3 1/2 * 12 = 18 * x

7/3 or 2 1/3 = x

Katrina needs 3/5 kilogram of flour for a recipe. Her mother has 3/7 kilogram of flour in her pantry. Is this enough flour for the recipe? If not, how much more will she need?

Answers

No, if you convert 3/5 and 3/7 into like fractions, you would get 3/5=21/35 and 3/7=15/35 therefor, you will need 6/35 kilogram more flour.

No, the flour is not enough to make the recipe; Katrina will still need 6/35 kilograms of flour.

The amount of flour Katrina needed is 3/5kgThe amount of flour Katrina had is 3/7kgFurther Explanation

To get the amount of kilogram that Katrina will still need, you should subtract the amount of flour Katrina needed from the amount she had.

This implies 3/5-3/7.

You have to find the smallest number that can divide the denominators (5 and 7) and since 35 is the smallest number that can divide both denominators, then it is the lowest common denominator or LCD.

You should now divide the denominators with 35, and also multiply the answer you get with the numerators.

This implies 3/5-3/7 = 21/35-15/35

= 6/35kg.

The final answer is 6/35, which means Katrina will still need 6/35 kilograms more of flour.

As you can see, we arrived at the final answer by subtracting the numerators (21-15) to have 6, and the lowest common denominator remains 35.

If you are faced with questions that require you to find the smallest number or LCD for large numbers, what you should do is to multiply the denominators together and reduces it if necessary.

50-10x=20 what is the value of x in this problem

Answers

So what I did was I wrote down the problem 50 - 10x = 20.

The first step I did was take 50 and subtract it from both sides: 50 - 10x = 20
                                                                                                   -50            -50
After that i cross out the so 50's and take 20 and subtract it to 50 which gave me -30. So when you write this down you rewrite it as: -10x = -30

Last step: take the -10 and divide it by both sides the cross out the two -10's cause it's going to be written as -30/-10 which would give you x = 3. So there is your answer, hope this helps. :)

~Shadow


To find the value of x in the equation 50 - 10x = 20, we subtract 50 from both sides and then divide by -10, leading to x = 3.

To solve the equation 50 - 10x = 20 for the value of x, we need to isolate x on one side of the equation. First, we subtract 50 from both sides, which gives us -10x = -30. Next, we divide both sides by -10 to solve for x, resulting in x = 3. This process demonstrates the systematic approach to solving linear equations, ensuring accurate determination of unknown variables and facilitating problem-solving in various mathematical contexts. Once simplified, the equation x=3 represents the solution where the given expression is true, providing clarity on the value of x that satisfies the equation.

A pencil Company used 60 grams of rubber to make 10 pencils how many pencils can be made with 50 grams of rubber

Answers

with 50 grams of rubber, you can make approximately 8 pencils.

To solve this problem, we need to set up a proportion to find out how many pencils can be made with 50 grams of rubber.

Let's set up the proportion using the given information:

[tex]\[\frac{\text{Grams of rubber}}{\text{Number of pencils}} = \frac{60}{10} = \frac{50}{x}\][/tex]

Where:

- 60 grams of rubber is used to make 10 pencils.

- 50 grams of rubber is the amount we have.

- x is the number of pencils we want to find.

Now, let's solve for x:

[tex]\[\frac{60}{10} = \frac{50}{x}\][/tex]

Cross multiplying:

60x = 500

Dividing both sides by 60:

[tex]\[ x = \frac{500}{60} \][/tex]

x = 8.333

Since you can't make a fraction of a pencil, we need to round down to the nearest whole number because you can't make a fraction of a pencil. Therefore, with 50 grams of rubber, you can make approximately 8 pencils.

The probable question maybe:

A pencil Company used 60 grams of rubber to make 10 pencils how many pencils can be made with 50 grams of rubber?
