Write the equation in function form:
8x + 4y = 20

Answers

Answer 1
Write 8x+4y=20 in function form


Writing a an equation in function form is simply expressing y values in terms of x. In other words when you substitute a particular value for x, you get a particular value for y.

so

8x + 4y = 20

4y = 20 - 8x

y = (20-8x)/4 or y = (20-8x)/4 or y = f(x) = 2(10-4x)/4 = (10-4x)/2 = 5 - 2x = -2x+5

check your answer with a sample values say with a point that solves the equation or a point on the line.....see below....

(2,1)

8(2) + 4(1) = 20......16 + 4 = 20...check.......y=-2(2) + 5 = -4 +5 =1....x=2, y=1...checks....so f(x)=-2x+5

another quick check are the intercepts.....y (x=0)....or x (y=0)

8 (0) + 4 (5) = 20.....(0,5).......y=f(x) = -2 (0) + 5...x = 0..y=5 so again the function checks so

8x + 4y = 20.....is also written as the function y= f(x)= -2x + 5

2. If she wants to eat 175 calories of granola, how many servings should she eat?
3. Write an equation to represent the relationship between the number of calories and the number of servings of granola.

Answer: 350 Calories

Step-by-step explanation:

I did this in school hope this helps!

1. 1750/5=350 (to find out how many calories for 1 bar) 350*2=700
2. 300=1 serving and since you want 175 you set up a faction so you will have 300/1 = 175/? Then you would cross multiple and divide so 175*1= 175 and then divided 175/300= about 0.6 servings
3. 300:1

A basket contains 3 apples and 7 oranges. A fruit is drawn and put back into the basket. This process is repeated 3 times. What is the probability that selected three fruits are orange? **Please answer in fractions only!**

Answers

Answer:

the fraction of oranges in the basket would be 8/15 because we have 8 oranges and 15 fruits in total

Step-by-step explanation:

The probability for selection orange thrice from basket is 343/100.

What is the definition of the probability?Probability is synonymous with possibility. It is a mathematical branch that deals with incidence of a random event. The value ranges from zero to one. Probability has just been introduced in mathematics to predict the likelihood of events occurring.

A basket contains 3 apples and 7 oranges.

Total fruits = 10.

A fruit is selected from the basket three times with replacement.

The probability for the selection of one orange is 7/10.

The probability for the selection of second orange is 7/10.

The probability for the selection of third orange is 7/10.

Thus, the probability for selection orange thrice is;

Probability (3 times orange) = 7/10×7/10×7/10

Probability (3 times orange) = 343/100

Thus, the probability for selection orange thrice from basket is 343/100.

Alonzo will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $50 and costs an additional 0.10 per mile driven. The second plan has no initial fee but costs 0.60 per mile driven. How many miles would Alonzo need to drive for the two plans to cost the same?

Answers

Answer:

100 miles

Step-by-step explanation:

If Alonzo drives 0 miles, then the first plan would cost him 50 dollars and the second plan would cost him nothing.

If Alonzo drives 10 miles, then the first plan would cost him 51 dollars and the second plan would cost him 6 dollars.

From these statements, we can observe that the second plan is increasing at a rate 6 times the first one and will overtake it at one point.

Our solution is the point of intersection between these two functions - where they cost the same.

To find this, equate

0.1x + 50 = 0.6x

where x is the number of miles Alonzo drives,

multiply the equation with 10 to get,

x + 500 = 6x

subtract x,

5x = 500

and divide 5,

x = 100.

So at 100 miles, both plan 1 and 2 will cost 60$. This is our answer. Good Luck!

They both want to purchase a copy of the same book, which normally sells for $24.50 plus 10% sales tax. To check if she has enough to purchase the book, Tess takes 15% of $24.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Dan takes 85% of the normal purchase price and then computes 110% of the reduced price. Is Tess correct? Is Dan correct? Do they have enough money to purchase the book? Explain your answer using complete sentences, and show your work.

Which of the following represents, the difference of a number squared and four is less than or equal to five.

Answers

Answer:

x² - (4 ≤ 5)

Step-by-step explanation:

(I have x representing the number that is squared, it might be a different letter on your options, but regardless it will be the same general answer. You also may not need the parentheses around the 4 ≤ 5)

Difference means subtraction so we know that the second number/group of numbers will be subtracted from the first that is listed.

Next, if you are squaring any number it's going to have the little 2 to the right of it. That's what that means.

Then, we look at that last bit. "Four is less than or equal to five." This means exactly how it sounds. To write this we need the symbol ≤. This symbol means less than or equal to. You would would but the 4 in front and the 5 in back to get 4 ≤ 5.

Now we just put it together. It tells us that 4 ≤ 5 is being subtracted from a number squared. So this means that a number squared needs to be first, and because difference means subtraction, we would subtract 4 ≤ 5 from that. A number squared can be represented by any letter variable, but for this example, I will use x.

This leaves you with x² - (4 ≤ 5)

I hope this helped :)

An orchard sells apples in 5.5‐pound bags. The orchard sells 65 bags of apples each day.

How many pounds of apples does the orchard sell in 1 week?

The orchard sells
pounds in 1 week.

Answers

Answer:

2502.5 pounds

Step-by-step explanation:

Answer:

2,503 pounds

Step-by-step explanation:

Multiply the amount of bags sold by the number of days within a week.

65 x 7 = 455

In 1 week 455 bags of apples are sold.

The next step is to multiply the total amount of bags sold in 1 week by the pound of 1 bag of apples.

455 x 5.5 = 2,502.5lbs

2,503lbs (rounding to the nearest whole number) of apples are sold in 1 week.

Answers

Answer:

10 inches

Step-by-step explanation:

They're 36 degrees, so corresponding angles are the same, so the middle line is parallel to the bottom line of the triangle.

But the middle line bisects one of the waist lines of the triangle, so this is the middle line, which is equal to half the length of the bottom line

Someone please help. Explain why it might be easier to solve the multiplication problem by changing it from this: 5×98×2 , to this: 5×2×98 . Use a property of multiplication to justify your reasoning.

Answers

Answer:

Because it is easy to multiply 5 by 2 which is 10......and then 10 × 98 youbjust have to add 0 to 98.....which will be 980

The multiplication problem can be simplified by the equation A = 5 x 2 x 98 and the value of A = 980

What is an 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.

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 data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 5 x 98 x 2

On simplifying , we get

From the associative property , we get

A = ( 5 x 2 ) x 98

where the value of 5 x 2 = 10

So , the multiplication expression is

A = 10 x 98

A = 980

Therefore , the value of A is 980

Hence , the equation is A = 980
