-3+5+2y-7y

• first you combine like terms
• -7y and +2y are like terms because they both end with the variable "y"
•which gives you -5y because a negative and a positive you subtract and keep the sign of the larger number in this case would be -7y
• next you combine 5 and -3, since the numbers have opposite signs, you subtract and keep the sign of the larger number, which in this case would be 5 and the answer to +5-3 is 2.

Final answer: -5y+2

Answer:

a) 15:7

b) 1950 ml

c) There were 10 people in the group

Step-by-step explanation:

a) In its basic form, the ratio would be 750:350. However, to get it to it's most basic form, we must find the greatest common factor (GCF) of 750 and 350, which is 50. Then, we divide both numbers by the GCF so that 750 is 15 and 350 is 7. Therefore, the basic form of the ratio is 15:7.

b) First, we can find the amount of chicken stock needed for 12 people, which is just double of the recipe since the recipe is for 6 people. (900 * 2 = 1800). Then, we need to figure out how much chicken stock is required for one person since there are 13 and not 12. We can do this by multiplying 900 by 1/6 (since it's for 1 person out of the 6 people recipe) to get 150. Then, add the amount of chicken stock needed for 12 people and 1 person together. 1800 + 150 = 1950.

c) First, we must figure out how many grams of leeks are required for just one person. We can do this by taking the amount needed in the recipe (for 6 people) and dividing it by 6 to get the amount needed for 1 person. 750 divide by 6 is 125, so 125 g of leeks are required to make soup for 1 person. Then, we take the total amount of leeks that Delia used (1250) and divide that by 125 to get 10.

4. Identify whether each function is linear or non-linear. Then, evaluate the function for the given value of
ozzi

f(x) = x3 + 2x2 + 6  \\ f(3) = (3)3 + 2(3)2 + 6 \\  = 9 + 12 + 6 \\ f(3) = 28 \\  \\ f(x) = 1x  \\ f(8) = 1(8) \\  = 8 \\ f(8) = 8

I need to know if there functions or not (algebra)
faust18 [17]

Answer:

Number 14 is a function and Number 16 is NOT a function.

Step-by-step explanation:

To check if a set of numbers form a function, you can look at the x values or the imput values.

For number 14 the x values are : 4,-3,-4,5,6. When looking at these values, there can only be one of each number.

For example in number 16, there's two 0's and we cannot allow that! So therefore, number 16 is not a function.

Also note, the y values are called the outputs.

A function is only allowed to have ONE imput with each output.

Hope this helps! :)

Answer:C

Step-by-step explanation:

your answer is 390

First area of the rectangle which formula is bxh base time height.
